EBB3 gene

EBB3 gene is a plant gene and it stands for early bud-break 3. It is a positive regulator of ‘bud breaking’ i.e. the emergence of plants from a dormant vegetative phase to form buds. It gives a direct link to cell cycle activation during bud breaking. This is a temperature sensitive gene and is hence being affected by climate change leading to earlier bud breaks than normal. Another positive regulator of bud break is EEB1. SVL or short vegetative phase gene is a negative regulator of bud break.
