Identification of cold-inducible microRNAs in grapevine.

Low temperature is one of the most important environmental factors that limits the geographical distribution and productivity of grapevine. However, the molecular mechanisms on how grapevine responds to cold stress remains to be elucidated. MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs that play an essential role during plant development and stress responses.

In silico analysis on structure and DNA binding mode of AtNAC1, a NAC transcription factor from Arabidopsis thaliana.

NAC (NAM/ATAF/CUC) transcription factors regulate the expression of the target genes by formation of NAC-DNA complex, which are involved in development, stress responses and nutrient distribution in many metaphyta plants. AtNAC1, a NAC transcription factor from Arabidopsis thaliana, plays an important role in auxin signaling and root development. In order to understand the structure and DNA binding model of AtNAC1, the 3D structure model of AtNAC1 was constructed and docked with its target DNA.
