Jasmonic acid-dependent increase in the level of vegetative storage proteins in soybean

Interplant communication: airborne methyl jasmonate induces synthesis of proteinase inhibitors in plant leaves.

“…Previous studies have shown that methyl jasmonate, or jasmonic acid, when applied directly to plants can produce various responses, including growth inhibition (28,29), promotion of senescence and/or abscission (26,30), and induction of specific leaf proteins in monocots and dicots (31)(32)(33) …”

Induction of soybean vegetative storage proteins and anthocyanins by low-level atmospheric methyl jasmonate.

“…Soybean (Glycine max Merr cv. Wye) seeds were planted in potting compost in 7.6-cm pots and grown in a controlled environment chamber with a photon flux density of 360-400 microeinsteins m-2s-of photosynthetically active radiation at canopy height (1 einstein = 1 mol of photons), 16- various organs were extracted as described (15). Prior to electrophoresis, protein samples were heated at 900C for 5 min and then centrifuged at 13,000 X g for 3-5 min.…”

“…Direct applications of aqueous jasmonic acid also selectively induce the accumulation of two vegetative storage proteins (VSPs) of 27 kDa and 29 kDa in soybean plants and suspension cultures (15,16) and induce the expression of their respective mRNAs (17,18). Soybeans are able to temporarily store nitrogen in the form of these VSPs.…”

Methyl Jasmonate and Transpiration in Barley

“…It has been shown that treatment with low levels ofjasmonates can induce the formation of specific mRNAs and polypeptides (2,9) in leaves. At higher levels of jasmonate treatment, leaves also exhibit symptoms of rapid senescence as measured by the loss of Chl and the decline in Rubisco levels (9,12).…”
