Adaptation of the Photosynthetic Apparatus in Maize Leaves as a Result of Nitrogen Limitation : Relationships between Electron Transport and Carbon Assimilation.

abstract：:Inoculation of 2-day-old cowpea (Vigna unguiculata [L.] Walp.) seedlings with Rhizobium fredii USDA257 results in proficient nodulation of the tap root. The most abundant nodulation occurs in a region roughly corresponding to the position of the root tip at the time of inoculation. We have examined plant gene expressi...

abstract：:TAP46 is a protein phosphatase2A (PP2A)-associated protein that regulates PP2A activity in Arabidopsis (Arabidopsis thaliana). To study how PP2A is involved in abscisic acid (ABA) signaling in plants, we studied the function of TAP46 in ABA-regulated seed maturation and seedling development. Expression of TAP46 coinci...
