Gene Details:

• Gene ID: TEA014193.1
• Gene Symbol: CsMYB73
• Gene Name: R2R3-MYB transcription factor 73
• Genome:
• Species: Camellia sinensis

Functional Descriptions:

• CsMYB73 negatively regulates theanine accumulation mediated by CsGGT2 and CsGGT4 in tea shoots.
• CsMYB73 was confirmed to act as a nucleus-localized transcription factor (TF), directly interacts with the CsGGT2 and CsGGT4 promoters, serving as an activator of CsGGT2 and a suppressor of CsGGT4. Consequently, this leads to a negative association with theanine accumulation in tea shoots.
• Further experiments demonstrated that the transcription factor CsMYB73 bound directly to CsGGT2 and CsGGT4 promoters and negatively regulated theanine accumulation in the shoots of ‘Shuchazao’ from different seasons and in the shoots of ‘Huangkui’ during seasonal greening.
• CsMYB73 is negatively correlated with theanine accumulation mediated by CsGGT2 and CsGGT4 in tea shoots.
