Gene Details:

  • Gene ID:
  • Gene Symbol: PttPHYA
  • Gene Name: PHYTOCHROME A
  • Genome:
  • Species: Populus tremula L. × P. tremuloides

Functional Descriptions:

  • Earlier studies have shown that the photoreceptor phytochrome A (phyA) promotes growth.
  • We describe studies in which the expression of endogenous Populus tremula × P. tremuloides PHYTOCHROME A (PttPHYA) was reduced in Populus trees by antisense inhibition.
  • Strong down-regulation of PttPHYA causes earlier timing of growth cessation and bud set under CDL.
  • The expression of genes involved in daylength detection is altered in aPttPHYA plants under SD.
  • We conclude that the level of PttPHYA expression strongly influences seasonally regulated growth in Populus and is central to co-ordination between internal clock-regulated rhythms and external light/dark cycles through its dual effect on the pace of clock rhythms and in light signaling.
