The Genetic Control of Nectary Development

The nectary gland mediates the interactions between flowering plants and their pollinators defenders. Nectar is main reward to for pollination services. Understanding molecular basis of development has economic evolutionary significance. In rosids asterids, CRABS CLAW (CRC) a master regulator development. addition, CRC orchestrates carpel floral meristem termination controlled by B-, C-, E-class genes. basal eudicots, STY genes play key role in formation through auxin biosynthesis pathway. most important offered Since pollinator decline emerged as major threat agriculture, food demand growing globally, studying nectar utmost importance. Although genetic mechanisms that control angiosperm flowers have been quite well understood many years, maturation secretion synchrony with sexual organs appears be one flower’s best-kept secrets. Here we review findings controlling these processes. We also raise questions need addressed develop crop ecological functions take into consideration pollinators’ needs. putative TF controls processes such development, termination, formation. sugar-rich, phloem-derived solution contains products primary secondary metabolism. secretory nectar-producing organ formed anywhere on plant besides root. molecule binds DNA-regulatory sequence modulate rate gene transcription. concentric ring organs. family named after CRC-like appearance apically unfused carpels crc-1 mutant.
