Environmental and Genotypic Control of Assimilate Allocation in PlantsEntry ID: USDA0398
Abstract: "Environmental and Genotypic Control of Assimilate Allocation in
Plants" is a study that identifies mechanisms by which crop
plants adjust their sink capacity in response to growth
environment conditions. Systems examined include the following:
response to drought in maize endosperm and cassava leaf
primordia; response to elevated CO2 and high temperature in
potato tubers. In each system, emphasis ... is on alterations in
cell division mediated by responses to abscisic acid stress
hormone, sugar nutrient levels, and tissue water potential. The
purpose of this study is to identify physiological mechanisms by
which the environment controls assimilate accumulation,
translocation, and utilization in contrasting genotypes.
Quantify the critical physiological mechanisms that enhance
partitioning to grain during the phases of assimilate demands by
