Evolution of the Christmas Tree:  Firs Tie Oaks in Fitness Race

first_imgIn the struggle for existence, the conifers should have lost, because when angiosperms appeared, they had fancier valve jobs.  That’s the feeling of a story introduced by Elizabeth Pennisi on Science Now.  “Those of us who celebrate Christmas tend to take fir and spruce trees for granted around the holiday season,” she quipped, “But without a special modification that allows these trees to efficiently transport water, we might be hanging our ornaments on a ficus instead, according to a new study.”  She explained:In order for photosynthesis to occur, tall trees must supply their uppermost leaves with water, which is pulled up from the roots by evaporation.  Angiosperms such as oaks and willows accomplish this using a series of centimeters-long, tube-shaped cellular pipes.  Tiny valves made of cellulose membranes connect each “pipe” and help keep air bubbles out.  Christmas trees and other conifers have much shorter pipe cells, however, and therefore must use many more valves than angiosperms.  This should create more resistance and make it harder for them to transport water.  But they don’t have any trouble at all, says John Sperry, a plant biologist at the University of Utah in Salt Lake City.   (Emphasis added in all quotes.)Sperry’s team measured water flow in 18 conifers, including bald cypress, junipers and redwoods, and compared results with 29 species of angiosperms.  There was no essential difference.  Conifers hoisted the water with equal ease, despite the shorter pipe cells.  How do they do it?The reason, says [Jarmila] Pittermann, has to do with key differences in the valves.  Angiosperm valves are simple membranes full of miniscule pores.  In conifers, the valves consist of a circle of impermeable tissue surrounded by porous tissue.  The conifer’s pores are 100 times larger than those in angiosperms and allow water to pass through relatively easily.  This efficiency more than makes up for the additional valves on the way to the tree top, Pittermann says.The researchers said that this helps scientists understand water transport in wood.  “But the work also points to how conifers, which predate angiosperms and are often considered primitive, were able to survive once angiosperms populated Earth,” Pennisi explains.  “Without these very special cells, one biologist claimed “there wouldn’t be any conifers anymore” – presumably because they could not compete against the angiosperms.  The work was published in Science.1  In the paper, the authors did not explain how or when the unique structure of the conifer valve evolved.  They just said that without the adaptation, angiosperms would have a 38-fold advantage in water transport:The superior hydraulics of the conifer pit are crucial for minimizing sapwood resistivity.  If conifer tracheids had the pit resistance of angiosperms, their sapwood resistivity would increase by 38-fold…. This, added to the narrow diameter range of tracheids, would make it much more difficult for conifers to compete effectively with angiosperms.    …. We conclude that the evolution of the torus-margo membrane within the gymnosperm lineage from homogenous pits was equivalent to the evolution of vessels within the angiosperms.  The towering redwoods and the sweep of the boreal coniferous forest exist in no small part because of this clever microscopic valve.1Pitterman et al., “Torus-Margo Pits Help Conifers Compete with Angiosperms,” Science, 23 December 2005: Vol. 310. no. 5756, p. 1924 | DOI: 10.1126/science.1120479.What did evolution have to do with this story, really?  Did it contribute anything of value, even an ornament to hang on the tree?  The results were not what evolutionists expected.  Conifers ruled the Jurassic forests, then along come angiosperms with superior plumbing, and there should have been no contest.  Those old, primitive conifers should have gone the way of the dinosaurs, and our Christmas trees would look very different.  Sweep away the Darwinian mythology, and what remains?  Two well-designed, highly successful groups of plants.  They may have different ways of lifting water, but so what?  From a design perspective, it would be just as productive a research program to find reasons for the difference.  Clearly the conifers are doing well.  The tallest trees in the world are conifers (see 04/22/2004).  Conifers seem to do even better than angiosperms in many locations, such as at timberline, where they survive numbing cold storms and snow without even having to drop their needles.  Nobody told them they were at a disadvantage against the new trees on the block.    The gem of this story is the beautifully-designed valves in conifers that allow them to pump thousands of gallons of water straight up, hundreds of feet into the air, to fill our world with beauty and dignity (see photos #1, #2, #3) while adding to the life-giving oxygen in the atmosphere.  Pennisi jokingly entitled her article, “The Grinch Who (Almost) Stole Christmas” pitting angiosperms in a phony battle against their friends, the conifers.  Not funny.  The Grinch is Charles Darwin.(Visited 20 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Shedding some light on corn tassels

first_imgShare Facebook Twitter Google + LinkedIn Pinterest John BrienTasseling is just around the corner for most corn fields. The acres of green will soon be topped with shades of yellow, green or purple. What an exciting time in the life of a corn plant. The emergence of tassels not only marks the halfway point of the corn’s plant life but also signifies a major change within the corn plant.A major shift of priorities occurs once a corn plant tassels. Prior to tasseling, the corn plant is in a vegetative growth stage. The corn plant is focused on producing vegetation such as stalks, leaves and roots and maintaining a healthy defense system. Soon after tasseling the corn plant no longer is concerned about growth or maintaining a strong defense system, but the sole purpose of the corn plant becomes producing grain. All of the plants resources are redirected from plant growth to the formation of the largest ear possible.Driving down the road, the tassel is easy to recognize, but what is involved with the tassel? The tassel is a male flower. Remember that the corn plant contains both male flowers and female flowers (corn silks) on the same plant. The tassel consists of many smaller parts that work together to release pollen. The tassel itself consists of a center spike with varying amounts of branches. The center spike and branches hold structures called spikelet flowers. The spikelet flowers then hold the anthers (look like double barreled shotguns) and finally the anthers hold and release the pollen.The tassel has many built in safety control features to ensure the corn plant carries out a successful pollination. The first safety measure surrounds the emergence of the tassel from the corn plant. Pollen will not begin shedding until the tassel is fully emerged. The second safety measure ensures pollen is present when silks are most receptive. Tassels typically begin releasing pollen two or three days prior to silk emergence. By having pollen present when silks emerge, there is ample opportunity for silks to be pollinated. The third safety measure focuses on the fact that not all the silks emerge at once. Therefore, the entire tassel does not release pollen at once, but instead pollen shed usually begins at the center of the spike and then continues upward, downward, and outward over time with the lower branches being the last to release pollen. Pollen is shed for a total of five to eight days depending on the hybrid. The heaviest pollen shed period occurs on the third day. The extended pollen release almost eliminates the possibility of a total pollination failure.Pollen shed is critical to pollination success. To ensure pollination success, the tassel has built in a redundancy factor into the tassel. Pollen grains are developed in and dispersed by the anthers. The anthers are the structures that hang from the tassel during pollination. Each tassel contains two to five million grains of pollen; this equates to 2,000 to 5,000 grains of pollen for each silk. More than enough pollen will be present since only one grain of pollen is needed to fertilize a single silk.During pollination, pollen shed is not a continuous process. Pollen is released from the anthers only when temperature and moisture conditions are favorable. The anthers open and allow the pollen to pour out after dew has dried off the tassel. All the pollen from a single anther may be released in as little as three minutes. Spent anthers eventually drop from the tassel and are sometimes mistaken for the pollen itself when observed on the leaves or ground. The peak pollen shed period is in the morning between 9 a.m. and 11 a.m. A second pollination period can occur in late afternoon or evening as temperatures begin to cool.The tassel is a critical part of the corn plant’s ability to produce grain. There are many amazing details about how the corn plant works, the redundancy of over producing pollen, the tassel’s ability to shed pollen only under favorable conditions or when the silks are present, to name just a few. The corn plant is an amazing creation that when understood and managed can produce large rewards.last_img read more

20 hours agoWoodward’s suddenly talking: Why it’s good for Man Utd & fans

first_imgTagsTransfersOpinionAbout the authorChris BeattieShare the loveHave your say Woodward’s suddenly talking: Why it’s good for Man Utd & fansby Chris Beattie20 hours agoSend to a friendShare the loveCOMMENT: The timing couldn’t have been worse. He’d set himself up for a right hammering. Mockery. Scorn. Take your pick. This decision from Ed Woodward to go public for the first time in his six years in charge at Manchester United was, ahem, courageous…But in the end fortune, inevitably, favoured the brave. That interview with the United We Stand fanzine. Just weeks after a lengthy and open address to shareholders. It was no PR job. If it had been, the publishing and roll out of it would not have happened over the past week. And thanks to a strong performance from the players against runaway leaders Liverpool on Sunday, there was little room for the cynics to pore over and twist Woodward’s words into another never before considered reason why United are in the state that it is.Of course a thumping at home – and to the club’s most bitter of rivals – could’ve led to a very different reaction. But it can be argued the backlash would not have been as bad as anything that flashed across Woodward’s mind.So the message to United’s vice-chairman exec should be: more of the same please. As mentioned, Woodward has said more publicly in the past month than the support have heard from him for the past six years. And the club, the fans and their relationship are better for it. After Woodward’s conference with United shareholders last month, this column encouraged him to speak more publicly. Our idea was a regular spot on the club’s in-house TV channel. But he went one better.Bypassing the media. Ducking their filter. Woodward went straight to the most valuable stakeholders of them all. And reading through the interview, it appears next to nothing was off limits.And the result is – or at least should be – a far happier supporter base and a less tense atmosphere around the club. Woodward did go into detail – deep detail – on various topics: the overhaul of the scouting team, the position of the Glazers, even the three-year scouting process of Daniel James. And fans should be examining everything carefully. Woodward was effectively giving you the blueprint of what United are now working from.Mistakes had been made. Problems had been allowed to grow, “…recruitment wasn’t at its best in recent years”. But a line’s now been drawn. The plan has been drawn up and put into action. The gist of it being, as this column’s sources have insisted since Christmas, United are going back to their roots. Their traditions.Discussing the prototype of today’s Manchester United signing, Woodward echoed the words of Dave McPherson, the former Hearts and Rangers captain, when discussing with this column the players of his era. It was about being “humble, but arrogant too”. In other words, United are rightly looking back to go forward.As Woodward said, “…we want players to come in who respect their teammates, the club, the history. They must understand that they are creating a legacy by coming to Manchester United. Nobody is bigger than the club.”There should be both a humbleness and an arrogance. Humble when you are on the team coach and you wear the club suit, you do up your top button and wear your tie, you represent the club in the right way. Then you sign autographs for the people who pay your wages.”Then, when you go into the dressing room, you put the red shirt on and you feel arrogant, self assured.”Essentially, Woodward was putting a bit more meat on the bones he offered shareholders – as it should be. And as much as the support can feel a little better about knowing the club’s plans; by being so open about their new approach Woodward also helps his manager in his work.Just as he did on that conference call, Woodward spelt out the reasons for Ole Gunnar Solskjaer’s appointment and the board’s expectations. Which are fundamentally based around the long-term.”As Michael Carrick said in his book, you want to take the ball, you want the ball in tight spaces, you want a never-say-die spirit. Ole has brought a lot of the discipline back,” said Woodward, revealing he had actually read the recently released book of United’s assistant coach.“Whatever manager we have has to buy into that philosophy and Ole is a walking, talking version of that. Let’s let this play out with Ole in terms of the culture reboot.” Which effectively puts paid to all that talk about Max Allegri’s English lessons. The situation around Mauricio Pochettino and Tottenham. Plus any old tenuous link between United and the likes of Thomas Tuchel, Julian Nagelsmann et al. The stories will be raised and floated. But they’ll also have a hollow ring to them. All thanks to Woodward’s words. Again, the club is in a better state thanks to the vice-chairman going public.This interview was a service to the support. Every United fan that reads it is better informed and has a more clear understanding of where the club wants to go. It may’ve been courageous, but it was needed.And no matter the timing or circumstances Woodward – for the good of Manchester United – needs to do more of it. last_img read more
