• Inhibition of petal expansion in Arabidopsis

As most of the work of jasmonates did in model plant Arabidopsis, so numerous roles of JA could be found in Arabidopsis, but some positive roles are also found in

The twin challenges like declining food and nutritional security and changing climatic scenario require the use of such biotechnological, physiological, genetical, and agronomical strategies to accomplish the demands of food to exploding population. Increasing abiotic stress made land barren or unutilizable for crop production. Tolerance to biotic and abiotic stresses is a challenge of agro-economic impact. Moreover, in a field condition additive effect of a number of stresses may further result in decreased soil fertility and crop yields. Researches on tolerance mechanisms and cross talks by phytohormones proved to be constructive for researchers in developing tolerant plants against particular stress. From the above information on jasmonates, the role of jasmonates in plant development is very well established but there is limited information available in the literature on how plant processes vary from species to species with JA application; a large number of components/ genes of JA/MeJA including its receptors have been identified, but their appropriate functions still need to be explored, also various genes involved in growth regulation

Other key roles of jasmonates are:

• Delay of flowering in Arabidopsis

• Promotion of trichome formation

• Gravitropism in plants
