Germination of soybean embryonic axes: nucleotide sugar metabolism and initiation of growth.
UDP-Sugars comprise the dominant class of nucleotide sugars in isolated soybean axes during early germination. While "dry" axes contain 1 nanomole per axis of UDP-sugars, further synthesis is initiated upon imbibition such that the concentration of total UDP-sugars reaches 8 nanomoles per axis or roughly 1 millimolar after 10 hours, when the axes begin to elongate. The GDP-sugars are essentiall...
متن کاملTranscriptome analysis uncovers key regulatory and metabolic aspects of soybean embryonic axes during germination
Soybean (Glycine max) is a major legume crop worldwide, providing a critical source of protein and oil. The release of the soybean genome fuelled several transcriptome projects comprising multiple developmental stages and environmental conditions. Nevertheless, the global transcriptional patterns of embryonic axes during germination remain unknown. Here we report the analysis of ~1.58 billion R...
متن کاملOxidative Stress Affects [alpha]- Tocopherol Content in Soybean Embryonic Axes upon Imbibition and following Germination.
The content of [alpha]-tocopherol ([alpha]T) in isolated soybean (Glycine max, var Hood) embryonic axes was measured upon germination. Dry, high-vigor axes contained 1.2 [plus or minus] 0.1, nmol/axis and after an increase during the initial 6 h of imbibition, there was a decline to 1.0 [plus or minus] 0.1 nmol/axis at 24 h of incubation. Incubation in the presence of the redox-cycling agent pa...
متن کاملPurine nucleotide metabolism of germinating soybean embryonic axes.
Isolated soybean (Glycine max L. cv. Kent) embyronic axes metabolized [(14)C]glycine to ATP within the 1 hour of imbibition. Radioactivity was not detected in GTP until the 3rd hour. Throughout most of the first 24 hours of germination about 10 to 26 times as much label from [(14)C]glycine appears in ATP as GTP. About five times as much [(14)C]hypoxanthine and [(14)C]inosine was converted into ...
متن کاملAdenylate metabolism of embryonic axes from deteriorated soybean seeds.
RNA and protein syntheses in axes excised from dry soybean (Glycine max L.) seeds at different levels of deterioration were assayed. Low rates of protein synthesis in slightly deteriorated seeds were not due to losses in ribosomal or soluble fraction activities. However, the lowered rates of RNA and protein syntheses of deteriorated seeds were associated with reduced ATP content of the tissues....
