A facile test system based on the accumulation of benzo[c]phenanthridine alkaloids in Eschscholzia californica cell suspension culture (an indicator of defense gene activation) has been used to analyze a series of synthetic compounds for elicitor-like activity. Of the 200 jasmonic acid and coronatine analogs tested with this system, representative results obtained with 49 of them are presented ...
Germination is considered a critical step in the development cycle of plant. But no information available regarding seed priming with Putrescine, Jasmonic acid, Kinetin, Potassium Nitrate (KNO3), Salicylic acid at time aged and non-aged seeds sorghum cultivars. However, to know effect aforesaid chemicals cultivars on germination rate, vigour alpha-amylase activity, research was conducted under ...
; Plants respond to various abiotic stimuli by activation and propagation of fast electrical signals, action potentials. To resolve the temporal increase in cytosolic Ca during the action potentials of higher plants, we regenerated transgenic potato plants that expressed the Ca photoprotein apoaequorin. These genetically engineered potato plants were used for simultaneous measurements of transi...
The green alga Chlorella pyrenoidosa was examined for its ability to metabolize 13-hydroperoxylinoleic and 13-hydroperoxylinolenic acids. The study showed that Chlorella extracts possessed hydroperoxide dehydrase and other enzymes of the jasmonic acid pathway. However, under normal laboratory conditions for culture growth, neither jasmonic acid nor metabolites of the jasmonic acid pathway were ...
Experiments with Arabidopsis mutants and sensitive and tolerant pairs in several other species have elucidated the molecular basis of plant ozone sensitivity and ozone lesion development. They have indicated an important role for hormonal signalling in determining the outcome of ozone challenge at the cellular level. The reactive oxygen species (ROS) from ozone degradation can cause either dire...
Jasmonic acid, synthesized from linolenic acid (the octadecanoid pathway), has been proposed to be part of a signal transduction pathway that mediates the induction of defensive genes in plants in response to oligouronide and polypeptide signals generated by insect and pathogen attacks. We report here that the induction of proteinase inhibitor accumulation in tomato leaves by plant-derived olig...
