Receptor-like kinase ERECTA negatively regulates anthocyanin accumulation in grape.

Receptor-like kinase (ERECTA, ER) is essential for mediating growth, development, and stress response signaling pathway in plants. In this study, we investigated the effect of VvER on anthocyanin synthesis as a regulatory factor in transgenic grape callus in response to chilling stress. Results showed that overexpression of VvER reduced the expression of transcription factors VvMYBA1, VvMYB5b, VvMYC2, and VvWDR1, as well as the structural genes VvCHS, VvCHI, VvDFR, VvLDOX, and VvUFGT, and inhibited the anthocyanins synthesis of grape callus at 25℃.

[APPLICATION OF THE DOUBLE SKIN PADDLE ARTERIALIZED VENOUS FLAPS FOR RECONSTRUCTING SOFT TISSUE DEFECTS OF MIDDLE AND PROXIMAL PARTS OF DOUBLE FIGURES].

Objective: To investigate the application of the double skin paddle arterialized venous flaps for reconstruction of soft tissue defects in the middle and proximal parts of double fingers.

Methods: Between September 2011 and December 2014, 6 cases (12 fingers) of soft tissue defects in the middle and proximal parts of double fingers underwent reconstructive surgery with the double skin paddle arterialized venous flaps. There were 5 males and 1 female with an average age of 33.
