The pear (Pyrus pyrifolia) is an important accessory fruit in which the core tarter than pulp. However, reason for acidic and diversity taste of same not clear. In this study, we observed that citrate contents were three times higher pulp, while malate content decreased along with development was significantly lower pulp at 110 days after flowering. Overall transcript levels citrate-malate synt...
We examined the effects of urease and hydrogenase assembly gene deletions on NikR activation in H. pylori strains 26695 and G27. The loss of any component of urease assembly increased NikR activity under Ni2+-limiting conditions, as measured by reduced transcript levels and 63Ni accumulation. Additionally, SlyD functioned in urease assembly in strain 26695.
The oxidative burst has been suggested to be a primary event responsible for triggering the cascade of defense responses in various plant species against infection with avirulent pathogens or pathogen-derived elicitors. The molecular mechanisms of rapid production of active oxygen species (AOS), however, are not well known. We isolated homologs of gp91 phox, a plasma membrane protein of the neu...
Brassinosteroids promote soybean epicotyl elongation and regulate expression of BRU1, a gene with homology to xyloglucan endotransglycosylases (XETs). Recombinant BRU1 protein possesses XET activity and in situ hybridization reveals highest BRUl transcript accumulation in inner epicotyl tissue, particularly the phloem and paratracheary parenchyma cells. These results suggest a role for BRUl in ...
Background: Ascorbate biosynthesis in plants occurs mainly via the L-galactose pathway. Results: Chlamydomonas reinhardtii VTC2 encodes a GDP-L-galactose phosphorylase whose transcript levels are induced in response to oxidative stress concurrent with increased ascorbate accumulation. Conclusion: Increased oxidative stress in C. reinhardtii results in an enzymatic and nonenzymatic antioxidant r...
