I am actively seeking individuals to serve as Grand Awards Judges for the upcoming event. The ISEF is the premier world-wide showcase for student researchers from grades 9-12. This year students from 45 different countries compete for over $4 million dollars in cash awards, scholarships and special awards. In order to assure the quality of our winners, we need your help. As professionals in the biological sciences, you provide the knowledge and expertise necessary to choose the absolute best student finalists from among the many excellent research projects at this year's Fair. If you or your collegues are interested in becoming a Grand Awards judge this year, please visit the official ISEF website: http://www.sciserv.org/isef/judges/index.asp or feel to contact me via e-mail at kroberts@pgcc.edu or by phone at (301) 386-7544. Thanks for your consideration, and I hope to hear from you. Karl J. Roberts, Ph.D. Plant Sciences Grand Awards Co-Chair Intel ISEF From monroejd from jmu.edu Wed Mar 4 10:03:46 2009 From: monroejd from jmu.edu (Jon Monroe) Date: Wed Mar 4 10:04:18 2009 Subject: [Plant-education] balancing the photosystems Message-ID: <49AE9852.8060704@jmu.edu> Hi Plant-eders, I really like describing the mechanism for balancing light input into the two photosystems of chloroplasts (redox state of PQ, activation state of a protein kinase, phosphorylation state of LHC, location of LHC in stacked or unstacked regions...) but I can't understand part of it and hence my students are frustrated. The reason the two photosystems can be unbalanced is because they operate at different wavelengths (680, 700 nm), and all would make sense if those were the /only/ wavelengths received by the photosystems, but they aren't. Arrays of chl a, b and beta-carotene surround each photosystem allowing photos of many wavelengths to donate their energy to the reaction centers. I recall learning that from mid-day to dusk the quality of light changes and that this was the difference, but is this really enough? Could it be that a leaf shifting between full sun and canopy shade, in which the ratio of red to far red light changes, is part of this story? Help! Thanks.
