Genome-wide identification of the CYP82 gene family in cucumber and functional characterization of in regulating resistance to powdery mildew.

The cytochrome P450 (CYP450) gene family plays a vital role in basic metabolism, hormone signaling, and enhances plant resistance to stress. Among them, the CYP82 gene family is primarily found in dicots, and they are typically activated in response to various specific environmental stresses. Nevertheless, their roles remain considerably obscure, particularly within the context of cucumber.

Overexpression of cucumber CYP82D47 enhances resistance to powdery mildew and Fusarium oxysporum f. sp. cucumerinum.

Cytochrome P450s are a large family of protein-encoding genes in plant genomes, many of which have not yet been comprehensively characterized. Here, a novel P450 gene, CYP82D47, was isolated and functionally characterized from cucumber (Cucumis sativus L.).

Changes of DNA methylation of Isoetes sinensis under Pb and Cd stress.

To investigate the molecular response of ancient plants to heavy metal stress and to explore the feature of DNA methylation in endangered plants after exposure to heavy metals, the Isoetes sinensis, an endangered plant, was stressed with three different concentrations of two heavy metals lead (Pb) and cadmium (Cd), respectively. Then the degrees and the patterns of DNA methylation in the leaves were measured on the 14th day using Methylation Sensitive Amplified Polymorphism (MSAP) technique. The results showed that the DNA methylated profile of I.

Effects of Lead on Ultrastructure of Isoetes sinensis Palmer (Isoetaceae), a Critically Endangered Species in China.

Isoetes sinensis Palmer (Isoetaceae) is a critically endangered fern that is a marsh plant (that is an aquatic or amphibious plant) in China. To evaluate damage or influence of lead (Pb) on cell ultrastructure in I. sinensis, we used 2000mg·L-1 Pb(NO3)2 solution to treat I.

Gene cloning and expression of MAP30 in .

MAP30, a single-stranded type-I ribosome inactivating protein found in , shows anti-HIV and anti-tumour activity. It could significantly inhibit the HIV-1 and herpes simplex virus infection. In this study, we tried a safe and convenient expression system supplying MAP30 protein for medical practice.
