Article Abstract
The eggplant was mutagenized with ethyl methane sulfonate (EMS) to enhance its genetic variability in our previous paper. In this article, we further analyzed the phenotype of M generation of mutant eggplants. A total of 325 independent M families were investigated for phenotypic variation. In addition to the visible phenotypic variation, chlorogenic acid (CGA) concentrations were analyzed in 26 fruits of mutants with High Performance Liquid Chromatography assay. Seventeen fruits exhibited significantly higher concentrations of CGAs than those in wild-type. The anthocyanin concentration of S9-1, the purple black mutant, was higher than WT, meanwhile, the anthocyanin concentration of L6-4 and U36-1 was lower than WT. Furthermore, our RT-PCR result demonstrated that the expression levels of anthocyanin biosynthetic genes, except for SmPAL, were increased in S9-1, and the regulator was decreased in L6-4 and U36-1 mutants. Together, our data indicated that, M generation showed abundant phenotypic variations and the strong potential usage for next step of breeding and molecular genetic mechanisms in eggplant.

Mutations in BrMYB31 lead to a glossy phenotype caused by a deficiency in epidermal wax crystals in Chinese cabbage.

Mutations in BrMYB31 were responsible for glossy phenotype, which was verified in two allelic mutants and gene silencing analysis. BrMYB31 regulated wax biosynthesis by modulating BrCER4 expression in Chinese cabbage. Plant cuticular wax plays a crucial role in resisting both biotic and abiotic stresses, but its deficiency is beneficial for improving the commercial properties of certain leafy vegetables.

Both endogenous and exogenous genotoxins can inflict damage on cellular DNA, leading to reduced genomic stability in plants, which adversely affects development. Apoptosis Antagonizing Transcription Factor (AATF), also referred to as Che-1, has been identified as a binding protein for RNA polymerase II. It plays a crucial role in various cellular processes, including cell proliferation, transcriptional regulation, apoptosis, DNA damage response, and ribosome biogenesis in mammals.

The SOS response contains a set of about 45 genes related to the repair or tolerance to DNA damage. These genes are normally blocked but when lesions upon the genetic material occur an SOS signal is generated allowing their expression. Most types of DNA lesions must be modified or processed to induce SOS.

BrATG5 encoding autophagy protein was fine-mapped through MutMap and KASP analysis, and its function in regulating leaf senescence was verified using virus-induced gene silencing and functional complementation assays in Chinese cabbage. Leaf senescence is the final stage of leaf development, and is accompanied by the breakdown of organelle and catabolism of chlorophyll and macromolecules. The generated nutrients are supplied to developing seeds or other growing organs.

The chromosome aberration test (CAT) is a widely used in vitro assay for detecting structural chromosomal damage induced by clastogenic chemicals. It plays a crucial role in genetic toxicology, helping assess the potential genotoxic effects of pharmaceutical compounds, environmental contaminants, and industrial chemicals. This test is particularly valuable in regulatory studies, as chromosomal aberrations are linked to mutagenicity, carcinogenicity, and hereditary diseases.
