Abstract:
... Seeds represent an excellent opportunity to investigate the role of reactive oxygen species (ROS) in control of metabolism during germination and seedling establishment. Cotyledons, the storage organs in Vigna, do not display growth/cell division while the embryonic axis shows rapid growth and intense metabolic activity. The present study investigates the possibility of ROS generated during respir ...

Abstract:
... Galactinol is the galactosyl donor for the biosynthesis of both the raffinose family oligosaccharides (RFOs) and galactosyl cyclitols (Gal-C). Its synthesis by galactinol synthase (GolS, EC 2.4.1.123) is the first committed step of the soluble α-d-galactosides biosynthetic pathway in orthodox seeds. The deposition of galactosides in seeds is suggested to be associated with desiccation tolerance (D ...

This study examined the optimal atmospheric CO2 concentration of the CO2 fertilization effect on the growth of winter wheat with growth chambers where the CO2 concentration was controlled at 400, 600, 800, 1000, and 1200ppm respectively. I found that initial increase in atmospheric CO2 concentration dramatically enhanced winter wheat growth through the CO2 fertilization effect. However, this CO2 f ...

We performed a comprehensive nuclear proteome analysis of Citrus sinensis during interaction with host (Xanthomonas citri pv. citri-Xcc) and non-host (Xanthomonas oryzae pv. oryzae-Xoo) pathogens. The nuclear proteome was obtained using a sequential method of organelle enrichment and determine ...
