beyond imagination!

To describe something that is slow and boring, we say that it is "like watching grass grow.

Just as the sunrise stimulates the dawn chorus of birds, the sunrise also stimulates the dawn burst activity of plants

Early morning is an important time for plants

This internal biological clock helps plants prepare for the day, such as when to make the most of sunlight, when to open flowers for pollinators, when to release pollen, and when to prepare for drought

The peak of gene activity occurs within an hour before dawn; many of these genes are coding for transcription factors, which are proteins that regulate downstream gene expression, and their effects are related to light, stress and growth hormone, but they are still It is not clear how this peak is controlled

Researchers at the University of Cambridge’s Sainsbury Laboratory (SLCU) and University of York (University of York) began investigating this mutational activity in order to better understand what is happening at the genetic level

"We intend to describe the dynamics of the'dawn burst' in more detail, focusing on the expression of transcription factor genes

"It is known that many of these genes are sensitive to light and temperature, but we want to find out how the transcription of these genes is coordinated

The team integrated their data with published transcription factor-DNA binding data, and at dawn identified a gene regulatory network, the core of which is two key regulators of light signals-HY5 and BBX31

"In fact, multiple BBX genes together with BBX31, HY5 and their homologous gene HYH form part of the dawn outbreak," said Dr.

Dr.

"Describe the gene expression peaks we see at the beginning of the light, which helps us understand how plants respond to light, especially for crops grown under artificial light, how this dawn has a long-term effect on growth.
