Biochemical 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...

متن کاملMorphological characteristics of colony development in Micromonospora chalcea.
Colonies of Micromonospora chalcea display two types of mycelia. Vegetative mycelia are nonbranched, have a propensity for parallel disposition, and possess infrequent septa. The reproductive mycelia develop on their apical portion and are characterized by branching, frequent septation, and bearing of spores that are either sessile or at the end of small sporophores.
متن کاملGermination of single bacterial spores.
Changes in refractility and optical density occurring in individual spores of Bacillus cereus T and B. megaterium QM B1551 during germination were investigated by use of a Zeiss microscope photometer. The curves revealed that the germination process in single spores had two distinct phases; an initial rapid phase was followed by a second slower phase. Under the experimental condition employed, ...
متن کاملBiochemical studies of bacterial sporulation and germination. XXII. Energy metabolism in early stages of germination of Bacillus megaterium spores.
Dormant spores of Bacillus megaferium contain DPN+, TPN+, and FAD at levels comparable to those in log phase vegetative cells, but little or no reduced pyridine nucleotides are present. The levels of free nucleotides, the most abundant of which are the adenine nucleotides, are also similar in spores and cells. In cells, however, 80% of the adenine nucleotide pool is ATP, whereas in spores it is...
