Scholarcy highlights

  • The plant being sessile, need to manage their lifestyle under ongoing ecological constraints
  • The positive regulation of drought and high salinity responses in Arabidopsis was observed by SLs and this feature was associated with shoot- rather than root-related traits
  • The Arabidopsis max3 and max4 mutants are sensitive to drought and salt stress and display higher stomatal density and delayed abscisic acid-induced stomatal closure compared to wild type plants
  • It has been observed that the SL-deficient and SL-response mutants exhibited hypersensitivity to drought and salt stress and the features was associated with shoot related traits
  • The current list of these candidates involves both the classical and newly discovered phytohormones and the list is still continuing with the advent of novel growth stimulatory phytochemicals
  • The recent outlook for key hormones like ABA, ET, jasmonic acid, salicylic acid has put the clear categorization of plant hormones under two separate heads i.e., development and stress related
  • The SL has been recognized as an important emerging player in plant stress management
