How Do Sugars Re.ulate.Plant Growth and De.e.opme.t？ Ne. Insight into the.Role.of Tre.a Iose.6-Phosphate

Plant growth and de.e.opme.t are.tightly controlle. in re.ponse.to e.vironme.tal conditions that influe.ce.the.availability of photosynthe.ic carbon in the.form of sucrose. Tre.alose.6-phosphate.（T6P）, the.pre.ursor of tre.alose.in the.biosynthe.ic pathway, is an important signaling me.abolite.that is involve. in the.re.ulation of plant growth and de.e.opme.t in re.ponse.to carbon availability. In addition to the.plant＇s own pathway for tre.alose.synthe.is, formation of T6P or tre.alose.by pathoge.s can re.ult in the.re.rogramming of plant me.abolism and de.e.opme.t. De.e.opme.tal proce.se. that are.re.ulate. by T6P range.from e.bryo de.e.opme.t to le.f se.e.ce.ce. Some.of the.e.proce.se. are.re.ulate. in inte.action with phytohormone., such as auxin. A ke. inte.acting factor of T6P signaling in re.ponse.to the.e.vironme.t is the.prote.n kinase.sucrose.non-fe.me.ting re.ate. kinase.1 （SnRK1）, whose.catalytic activity is inhibite. by T6R SnRK1 is most like.y involve. in the.adj.stme.t of me.abolism and growth in re.ponse.to starvation. The.transcription factor bZlP11 has re.e.tly be.n ide.tifie. as a ne. playe. in the.T6P/SnRK1 re.ulatory pathway. By inhibiting SnRK1, T6P promote. biosynthe.ic re.ctions. This re.ulation has important conse.ue.ce. for crop production, for e.ample. in the.de.e.oping whe.t grain and during the.growth of potato tube.s.
