Vegetative storage protein (VSP) and VSP mRNA levels in soybean (Glycine max) leaves correlated with the amount of NH(4)NO(3) provided to nonnodulated plants. The mRNA level declined as leaves matured, but high levels of N delayed the decline. This is consistent with the proposed role for VSP in the temporary storage of N. Wounding, petiole girdling, and treatment with methyljasmonate (MeJA) in...

Jasmonates, derivatives of jasmonic acid, are lipid-derived oxylipins with cyclopentanone ring, produced as a result dioxygenation mediated by lipoxygenases. The biosynthesis acid is catalysed series different enzymes, starting from lipoxygenase, allene oxide synthase, cyclase and 12-oxophytodienoic reductase to the final three rounds β-oxidation. Consequently, few metabolites known jasmonates ...

Complementary biochemical and genetic approaches are being used to dissect the signaling network that regulates the innate immune response in plants. Receptor-mediated recognition of invading pathogens triggers a signal amplification loop that is based on synergistic interactions between nitric oxide, reactive oxygen intermediates and salicylic acid. Alternative resistance mechanisms in Arabido...

COMATOSE (CTS) encodes a peroxisomal ATP-binding cassette transporter required not only for beta-oxidation of storage lipids during germination and establishment, but also for biosynthesis of jasmonic acid and conversion of indole butyric acid to indole acetic acid. cts mutants exhibited reduced fertilization, which was rescued by genetic complementation, but not by exogenous application of jas...
