Methyl jasmonate alleviated salinity stress in soybean
TLDR
It is revealed that MeJA counteracted the negative effects of NaCl stress on plant growth, chlorophyll content, leaf photosynthetic rate, leaf transpiration rate, and proline content.Abstract:
We studied the role of methyl jasmonate (MeJA) in alleviating NaCl-induced salt stress on soybean growth and development in hydroponics medium. Soybean seedlings were exposed to 60 mM NaCl stress for 2 weeks, 24 h after the application of 20 and 30 µM MeJA. NaCl stress induced a significant reduction in plant growth, endogenous bioactive gibberellin (GA4), photosynthesis and transpiration rate, while a marked increase in the endogenous abscisic acid (ABA) and proline contents were recorded. MeJA application greatly mitigated the adverse effects of NaCl on soybean growth and endogenous hormones. MeJA significantly increased ABA levels, while the endogenous amount of GA4 was reduced by the application of NaCl. Our study revealed that MeJA counteracted the negative effects of NaCl stress on plant growth, chlorophyll content, leaf photosynthetic rate, leaf transpiration rate, and proline content.read more

Exogenous jasmonic acid can enhance tolerance of wheat seedlings to salt stress.
TL;DR: It is suggested that JA could effectively protect wheat seedlings from salt stress damage by enhancing activities of antioxidant enzymes and the concentration of antioxidative compounds to quench the excessive reactive oxygen species caused by salt stress and presented a practical implication for wheat cultivation in salt-affected soils.

Breeding for salinity resistance in crop plants: Where next?
TL;DR: It is concluded that soil salinity has not yet become a sufficient agricultural problem, other than on a local scale, to make salt resistance a high priority objective for plant breeders, and that enhancing the salt resistance of at least some crops will be necessary.

TL;DR: Genetic science offers the possibility of developing salt-tolerant crops, which, in conjunction with environmental manipulation, could improve agricultural production in saline regions and extend agriculture to previously unsuited regions.

Jasmonate-inducible plant defences cause increased parasitism of herbivores
TL;DR: It is shown that inducing plants with jasmonic acid increases parasitism of caterpillar pests in an agricultural field twofold, and elicitors of plant resistance may become useful in agriculture.
