Vitamin E is essential for seed longevity and for preventing lipid peroxidation during germination.
Tocopherols (vitamin E) are lipophilic antioxidants synthesized by all plants and are particularly abundant in seeds. Despite cloning of the complete suite of tocopherol biosynthetic enzymes and successful engineering of the tocopherol content and composition of Arabidopsis thaliana leaves and seeds, the functions of tocopherols in plants have remained elusive. To address this issue, we have is...
متن کاملChanges of Seed Germination during the Year
It is possible to conclude that typical course of graph which analyse course of germinability during the year at every cultivar is observable. Germination usually shows a minimum in December, but mainly in January and in February. Maximum of germinability is observed in the spring and summer time. This phenomenon isn’t result of the dormancy or secondary dormancy because during of long term see...
متن کاملNew Roles of Phytochromes during Seed Germination
Among the most important environmental sensors in plants are the phytochromes, members of a duplicatedgene family of photoreceptors. We characterized the functional diversification of this gene family with respect to a single ecologically important and highly environmentally sensitive process—germination—and thereby addressed the consequence of gene duplication in the evolution of environmental...
متن کاملExpression of an expansin is associated with endosperm weakening during tomato seed germination.
Expansins are extracellular proteins that facilitate cell wall extension, possibly by disrupting hydrogen bonding between hemicellulosic wall components and cellulose microfibrils. In addition, some expansins are expressed in non-growing tissues such as ripening fruits, where they may contribute to cell wall disassembly associated with tissue softening. We have identified at least three expansi...
متن کاملBiochemical Aspects of Protein Changes in Seed Physiology and Germination
Seed storage proteins are synthesized as sources of carbon, nitrogen and sulfur for the next generation of plants. Reactive oxygen species serve as second messengers for signal transduction; however, molecular targets of oxidant signaling have not been defined. Here, many researchers showes that ligand–receptor mediated signaling promotes reactive oxygen species– dependent protein carbonylation...
