Heading date is a major determinant of adaptability and yield potential in rice (Oryza sativa L.) and is influenced by photoperiod.Among chromosome segment substitution lines (CSSLs), the introgressio
In plants, endogenous small RNAs, including microRNAs (miRNAs) and trans-acting small interfering RNAs play an important role in biological processes such as development and stress responses.While the
Alkaline/neutral invertases (A/N-Invs) have attracted more attention due to the increasing findings in their physiological significance, subcellular locations and enzymatic properties.In Hevea brasili
NF-Y (NUCLEAR FACTOR-Y), a heterotrimeric transcription factor, is composed of NF-YA, NF-YB, and NF-YC proteins in yeast, plant, and animal systems.In plants,each of the NF-YA/B/C subunits forms a mul
Anthocyanins are natural food colorantsproduced by plants.They play important roles in the growth and development of these plants.Mulberry fruits are rich in anthocyanins, which have many potentially
