U.S. Department of Agriculture Urbana, IL 61801 Biochemical and molecular analysis of a new control pathway in assimilate partitioning Daniel R. Bush, USDA-ARS and Department of Plant Biology, University of Illinois at Urbana- Champaign $72,666 (21 months) Plant leaves capture light energy from the sun and transform that energy into a useful form in the process called photosynthesis. The primary product of photosynthesis is sucrose. Generally, 50 to 80% of the sucrose synthesized is transported from the leaf to supply organic nutrients to many of the edible parts of the plant such as fruits, grains, and tubers. This resource allocation process is called assimilate partitioning and alterations in this system are known to significantly affect crop productivity. We recently discovered that sucrose plays a second vital role in assimilate partitioning by acting as a signal molecule that regulates the activity and gene expression of the proton-sucrose symporter that mediates long-distance sucrose transport. Research this year showed that symporter protein and transcripts turn-over with half-lives of about 2 hr and, therefore, sucrose transport activity and phloem loading are directly proportional to symporter transcription. Moreover, we showed that sucrose is a transcriptional regulator of symporter expression. We concluded from those results that sucrose-mediated transcriptional regulation of the sucrose symporter plays a key role in coordinating resource allocation in plants. 2. U.

The Scientist : Speciation's Roots?
Volume 22 | Issue 5 | Page 19 By Alla Katsnelson Speciation's roots? About four years ago, Janne Lempe, then a graduate student at the Max Planck Institute for Developmental Biology in Tübingen, was hard at work on a series of experiments on the genetic regulation of flowering time in Arabidopsis thaliana. She crossed two strains, chosen for their difference in flowering time, and set off to the greenhouse to leave the seeds A normal Arabidopsis plant (center), surrounded by to grow. different hybrids formed by crossing two healthy plants. Researchers generally raise Kirsten Bomblies and Detlef Weigel, Max Planck Institute for Arabidopsis at 23° C, but with Developmental Biology, Tübingen the lab's main greenhouse full, Lempe plunked her experiment into the 16° C greenhouse next door. A few weeks on, her seedlings had produced stunted, stumpy, deformed versions of the hearty white-flowered weeds she was expecting. Her plants were not only unusually small, but their leaves were also covered in necrotic brown spots, and they'd failed to flower. ARTICLE EXTRAS Slideshow: Crossing Arabidopsis Strains Lempe's two starting strains, UK1 and UK3, were perfectly normal. So why would their offspring be sick? Right away, says Detlef Weigel, an evolutionary geneticist who supervised Lempe's doctoral research, "I thought this might have some bearing on speciation." Perhaps genes from one strain were incompatible with those in the other, creating in the offspring a gene-flow barrier, which is the first step to the evolution of a new species. Researchers have mapped genes in Drosophila that keep two species apart, but such studies can't resolve whether genetic incompatibilities drove speciation, or instead accumulated after the species diverged.
