Xanthophylls and abscisic Acid biosynthesis in water-stressed bean leaves.

abstract：:The architecture of wheat (Triticum aestivum) inflorescence and its complexity is among the most important agronomic traits that influence yield. For example, wheat spikes vary considerably in the number of spikelets, which are specialized reproductive branches, and the number of florets, which are spikelet branches t...
