Regulation of soybean seed germination through ethylene production in response to reactive oxygen species.
BACKGROUND AND AIMS Despite their toxicity, reactive oxygen species (ROS) play important roles in plant cell signalling pathways, such as mediating responses to stress or infection and in programmed cell death, at lower levels. Although studies have indicated that hydrogen peroxide (H(2)O(2)) promotes seed germination of several plants such as Arabidopsis, barley, wheat, rice and sunflower, the...
متن کاملStimulation of lettuce seed germination by ethylene.
Ethylene increased the germination of freshly imbibed lettuce (Lactuca sativa L. var. Grand Rapids) seeds. Seeds receiving either red or far-red light or darkness all showed a positive response to the gas. However, ethylene was apparently without effect on dormant seeds, those which failed to germinate after an initial red or far-red treatment. Carbon dioxide, which often acts as a competitive ...
متن کاملSeed germination in response to chemicals: effect of nitrogen and pH in the media.
Seed germination generally presents a peak in the next growing season after a fire. Among other factors associated with fire are the increase of soil nitrogen and changes in the pH of the soil. In this study, we addressed the question, whether or not the germination response of eight species is linked with the increase in pH and nitrogenous compounds in the germination media? We assessed the se...
متن کاملInvestigation Germination Characteristics of Wheat (Triticum aestivum L., cv. Chamran) in Response to Seed Aging
BACKGROUND: Seed aging is an important problem in developing countries which seeds stored in inappropriate condition. OBJECTIVES: Current research was carried out to study the effect of seed aging on quantitative parameters of wheat seeds (Chamran cultivar). METHODS: Experiment was carried out based on randomized complete block desi...
متن کاملEthylene-orchestrated circuitry coordinates a seedling's response to soil cover and etiolated growth.
The early life of terrestrial seed plants often starts under the soil in subterranean darkness. Over time and through adaptation, plants have evolved an elaborate etiolation process that enables seedlings to emerge from soil and acquire autotrophic ability. This process, however, requires seedlings to be able to sense the soil condition and relay this information accordingly to modulate both th...
