An S-domain receptor-like kinase, OsESG1, regulates early crown root development and drought resistance in rice.

Plant receptor-like kinase (RLKs) are serine/threonine protein kinases that play fundamental roles in development, innate immunity, and abiotic stress response. Here, we identified an S-domain receptor-like kinase OsESG1 from rice (Oryza sativa), and identified its involvement in early crown root (CR) development and drought response. The OsESG1 kinase domain possessed auto-phosphorylation activity and was able to phosphorylate MBP and His proteins.

Evaluating the Effect of Expressing a Peanut Resveratrol Synthase Gene in Rice.

Resveratrol (Res) is a type of natural plant stilbenes and phytoalexins that only exists in a few plant species. Studies have shown that the Res could be biosynthesized and accumulated within plants, once the complete metabolic pathway and related enzymes, such as the key enzyme resveratrol synthase (RS), existed. In this study, a RS gene named PNRS1 was cloned from the peanut, and the activity was confirmed in E.

Overexpression of peanut diacylglycerol acyltransferase 2 in Escherichia coli.

Diacylglycerol acyltransferase (DGAT) is the rate-limiting enzyme in triacylglycerol biosynthesis in eukaryotic organisms. Triacylglycerols are important energy-storage oils in plants such as peanuts, soybeans and rape. In this study, Arachis hypogaea type 2 DGAT (AhDGAT2) genes were cloned from the peanut cultivar 'Luhua 14' using a homologous gene sequence method and rapid amplification of cDNA ends.

[Effects of early growth stage shading on rice flag leaf physiological characters and grain growth at grain-filling stage].

In a pot experiment, rice plants were shaded during the period from transplanting to booting, aimed to study the effects of early growth stage shading on the rice growth at grain-filling stage. Comparing with the control, early growth stage shading decreased the tiller number by 26.72%, but increased the flag leaf area and soluble sugar content by 33.
