SALICYLIC ACID INHIBITION OF GERMINATION, ETHYLENE PRODUCTION AND RESPIRATION IN COCKLEBUR SEEDS
Salicylic acid (SA) inhibited germination of cocklebur (Xanthium pennsylvanicum Wlr), lower seeds, which are completely after-ripened and nondormant. SA also inhibited ethylene production during a pre-germination period of the seeds. Exogenous ethylene overcame the inhibtion of the seed germination by SA. Moreover, SA reduced respiration in pre-germinating whole seeds as well as excised axial...
متن کاملPhytochrome regulates gibberellin biosynthesis during germination of photoblastic lettuce seeds.
Germination of lettuce (Lactuca sativa L.) seed is regulated by phytochrome. The requirement for red light is circumvented by the application of gibberellin (GA). We have previously shown that the endogenous content of GA1, the main bioactive GA in lettuce seeds, increases after red-light treatment. To clarify which step of GA1 synthesis is regulated by phytochrome, cDNAs encoding GA 20-oxidase...

متن کاملActivation of gibberellin biosynthesis and response pathways by low temperature during imbibition of Arabidopsis thaliana seeds.
Exposure of imbibed seeds to low temperature (typically 4 degrees C) is widely used to break seed dormancy and to improve the frequency of germination. However, the mechanism by which temperature accelerates germination is largely unknown. Using DNA microarray and gas chromatography-mass spectrometry analyses, we found that a subset of gibberellin (GA) biosynthesis genes were upregulated in res...
متن کاملNucleotide sequence of a cationic peroxidase gene from the tropical forage legume Stylosanthes humilis.
Peroxidases (EC 1.1 1.1.7; donor: hydrogen-peroxide oxidoreductase) have been implicated in numerous physiological processes of potential importance in plant-pathogen interactions, including lignification (Walter, 1992), crosslinking of cell-wall components (Bradley et al., 1992), wound healing (Sherf et al., 1993), auxin oxidation (Grambow and Langenbeck-Schwich, 1979), and systemic acquired r...
