Summary: Biological nitrogen fixation catalyzed by nitrogenase contributes greatly to the global nitrogen cycle.Nitrogenase expression is subject to regulation in response to nitrogen availability.However, the mechanism through which the transcriptional activator NifA regulates nitrogenase double door security bars expression by interacting with PI
Beneficial effects of silicon (Si) on plants have primarily been studied in crop species under single stress.Moreover, nutrient acquisition-based responses to combination of biotic and abiotic stresses (a common situation in natural habitats) have rarely been reported, in particular in conjunction with soil amendments with Si.Pedunculate oak (Querc
Mutation in TP53 is a common genetic alteration in human cancers.Certain tumor associated p53 missense mutants acquire gain-of-function (GOF) properties and confer oncogenic phenotypes including enhanced chemoresistance.The colorectal cancers ultra violette lip balm (CRC) harboring mutant p53 are generally aggressive in nature and difficult to trea
