BHLH TRANSCRIPTION FACTOR NTMYC2A REGULATES CARBOHYDRATE METABOLISM DURING THE POLLEN DEVELOPMENT OF TOBACCO (NICOTIANA TABACUM L. CV. TN90)

Basic helix-loop-helix (bHLH) transcription factor MYC2 regulates plant growth and development in many aspects through the jasmonic acid (JA) signaling pathway, while the role of MYC2 in plant carbohydrate metabolism has not been reported.Here, we generated NtMYC2a-overexpressing (NtMYC2a-OE) and RNA-interference-mediated knockdown (NtMYC2a-RI) tra
