Subtilisin-like protease 4 regulates cold tolerance through cell wall modification in rice.

Rice is susceptible to cold temperatures, especially during the seedling stage. Despite extensive research into the cold tolerance mechanisms of rice, the number of cloned genes remains limited. Plant subtilisin-like proteases (SUBs or SBTs) are protein-hydrolyzing enzymes which play important roles in various aspects of plant growth as well as the plant response to biotic and abiotic stress.

Peptidomics comparison of plant-based meat alternatives and processed meat after in vitro digestion.

Plant-based meat alternatives (PMAs) is a new type of food that meets people's health needs, but the lack of awareness of its nutritional properties limits product development and promotion. Here, we compared the similarities and differences of the nutritional properties of PMAs and meat before and after in vitro simulation of gastrointestinal digestion by chemical composition analysis, peptidomics and bioactivity tests. The molecular weights of Plant-based meat alternatives derived peptides (PDPs) as well as meat-derived peptides (MDPs) in the beef and pork groups were mainly concentrated in the low mass range from 800 Da to 1500 Da.

Expression of Sucrose Transporters from Confer High Yield and Enhances Drought Resistance in Arabidopsis.

Sucrose is the predominant form of sugar transported from photosynthetic (source) to non-photosynthetic (sink) organs in higher plants relying on the transporting function of sucrose transporters (SUTs or SUCs). Many SUTs have been identified and characterized in both monocots and dicots. However, the function of sucrose transporters (SUTs or SUCs) from is not clear.

Overexpression of a Grapevine Sucrose Transporter (VvSUC27) in Tobacco Improves Plant Growth Rate in the Presence of Sucrose .

The import of sugar from source leaves and it further accumulation in grape berries are considerably high during ripening, and this process is mediated via sucrose transporters. In this study, a grape sucrose transporter (SUT) gene, , located at the plasma membrane, was transferred to tobacco (). The transformants were more sensitive to sucrose and showed more rapid development, especially roots, when cultured on MS agar medium containing sucrose, considering that the shoot/root dry weight ratio was only half that of the control.

Comparative Proteomic Insights into the Lactate Responses of Halophilic Salinicoccus roseus W12.

Extremophiles use adaptive mechanisms to survive in extreme environments, which is of great importance for several biotechnological applications.
