Scholarcy highlights

  • Phytohormones are plant growth regulators synthesized within plants that participate in many aspects of the plant life cycle, including responses to biotic and abiotic stress
  • While metabolism provides the energy needed for plant survival, hormones regulate the pace of plant growth
  • Strigolactones were recently defined as new phytohormones that regulate plant metabolism and, in turn, plant growth and development. This group of phytohormones is derived from carotenoids and has been implicated in a wide range of physiological functions including regulation of plant architecture, photomorphogenesis, seed germination, nodulation, and physiological reactions to abiotic factors
  • It was reported that cross-talk between SL and abscisic acid plays an important role in integrating stress signals to regulate stomatal development and function
  • There has been extensive research showing how important interactions between SLs and other phytohormones are for the regulation of plant growth and development
  • Past research has led to considerable insight into the physiological roles of SLs, it is obvious that new functions of SLs have yet to be discovered
  • Interdisciplinary research is an important tool to broaden the knowledge in this area
