In-gel protein kinase assays using myelin basic protein (MBP) as substrate have been used to demonstrate that abscisic acid (ABA) activates an MBP kinase (AMBP kinase) in epidermal peels prepared from leaves of the Argenteum mutant of pea, Pisum sativum L. AMBP kinase has the characteristics of a mitogen-activated protein kinase (MAPK): it utilizes MBP preferentially as an artificial substrate,...

Dehydrins are intrinsically disordered plant proteins whose expression is upregulated under conditions of desiccation and cold stress. Their molecular function in ensuring plant survival is not yet known, but several studies suggest their involvement in membrane stabilization. The dehydrins are characterized by a broad repertoire of conserved and repetitive sequences, out of which the archetypi...

Dehydrins (DHNs) play a crucial role in enhancing abiotic stress tolerance in plants. Although DHNs have been identified and characterized in many plants, there is little known about Capsicum annuum L., one of the economically important vegetable crops. In this study, seven CaDHNs in the pepper genome were identified, which could be divided into two classes: YnSKn- and SKn-type, based on their ...

Dehydrins (DHNs) compose a family of intrinsically unstructured proteins that have high water solubility and accumulate during late seed development at low temperature or in water-deficit conditions. They are believed to play a protective role in freezing and drought-tolerance in plants. A full-length cDNA encoding DHN (designated as ClDhn) was isolated from an oriental medicinal plant Codonops...

High temperature is a major environmental stress that devastatingly affects wheat production. Thenceforth, developing heat-tolerant and high-yielding genotypes has become more critical to sustaining production particularly under abrupt climate change fast-growing global population. The present study aimed evaluate parental their cross combinations normal heat conditions, exploring diversity bas...
