Vesicle trafficking delivers proteins to intracellular and extracellular compartments, cellulose synthase to the plasma membrane, and non-cellulosic polysaccharides to the cell wall. The Arabidopsis genome potentially encodes 19 proteins with sequence similarities to ARFs (ADP-ribosylation factors) and its relatives such as ARLs (ARF-like proteins). ARFs(More)
Hydration at low temperatures, commonly referred to as cold stratification, is widely used for releasing dormancy and triggering germination in a wide range of species including wheat. However, the molecular mechanism that underlies its effect on germination has largely remained unknown. Our previous studies showed that methyl-jasmonate, a derivative of(More)
Flavonoids have broad cross-kingdom biological activity. In Arabidopsis, flavonoid accumulation in specific tissues, notably the root elongation zone and root/shoot junction modulate auxin transport, affect root gravitropism, and influence overall plant architecture. The relative contribution made by aglycones and their glycosides remains undetermined, and(More)
Interest in the production of carbon commodities from photosynthetically fixed CO2 has focused attention on cyanobacteria as a target for metabolic engineering and pathway investigation. We investigated the redirection of carbon flux in the model cyanobacterial species, Synechococcus elongatus PCC 7942, under nitrogen deprivation, for optimized production(More)
