Genome-wide identification and expression analysis of the SPL transcription factor family and its response to abiotic stress in Pisum sativum L.

Squamous promoter binding protein-like (SPL) genes encode plant-specific transcription factors (TFs) that play essential roles in modulating plant growth, development, and stress response. Pea (Pisum sativum L.) is a coarse grain crop of great importance in food production, biodiversity conservation and molecular genetic research, providing genetic information and nutritional resources for improving agricultural production and promoting human health.

Effects of high hydrostatic pressure on the growth and beta-carotene production of Rhodotorula glutinis.

The effects of high hydrostatic pressure (HHP) on the biomass and beta-carotene biosynthesis of Rhodotorula glutinis R68 were studied. After treatment with five repeated cycles at 300 MPa for 15 min, the barotolerant mutant PR68 was obtained. After 72 h of culture, the biomass of mutant PR68 was 21.

[Mutation effect of ultra high pressure on microbe].

(Ultra) high pressure had many influences on microbe. It could regulate the expression of gene and protein, influence DNA's structure and function as well as change cell morphology and cell component. These effects not only make (ultra) high pressure to be applied into food sterilization, conserving and some processing, but also indicate it would play an important role in mutagenic breeding of microbe.
