Polyamines (PAs) are nitrogenous molecules that are indispensable for cell viability and with an agreed-on role in the modulation of stress responses. Tobacco plants with downregulated SAMDC (AS-SAMDC) exhibit reduced PAs synthesis but normal levels of PA catabolism. We used AS-SAMDC to increase our understanding on the role of PAs in stress responses. Surprisingly, at control conditions AS-SAM...
Shallot (Allium cepa L. var. aggregatum) cultivation is performed using True Seed (TSS) to obtain seedlings. However, it difficult handle when sowing directly, due the seed’s small and irregular shape. Therefore, encapsulation technology needed make TSS seeds have a larger size regular Shallots enable be more significant, roundshaped through encapsulation. This research was conducted combinatio...
seeds of most crops including those of range plants follow orthodox behavior. however, these seeds undergo aging even under favorable conditions, so that decreased viability and vigor related parameters are the main characteristics of deteriorated seeds. the effects of hormonal priming with auxin, cytokinin, gibberellin and abscisic acid at 0, 50, 100 and 150 ppm on physiological quality of tal...

Effects of Storage Temperature and Relative Humidity on Viability and Vigor of Treated Soybean Seeds
To assess whether heterozygosity of the donor cell genome was a general parameter crucial for long-term survival of cloned animals, we tested the ability of embryonic stem (ES) cells with either an inbred or F(1) genetic background to generate cloned mice by nuclear transfer. Most clones derived from five F(1) ES cell lines survived to adulthood. In contrast, clones from three inbred ES cell li...
Seed corn (Zea mays L.) producers in the Midwest region of the United States are affected by an early fall frost approximately every five years. The negative effects of frost on seed quality vary according to genotype and thus possibly seed composition. Our objective was to determine the effect of seed composition (oil and protein) and seed maturity on seed viability and vigor of artificially f...
