BBX32: A Protein that helps in Plant Growth Regulation

In a significant discovery, a team of scientists from the Indian Institute of Science Education and Research (IISER), Bhopal, recently identified a protein - BBX32 - that plays a critical role in plant growth regulation.

Context

• After a seed germinates, dicot plants develop two embryonic leaves called cotyledons. These remain in a folded state while the little seedling grows underneath the soil to reach the surface.
• Once the plant is exposed to light the cotyledons unfold, exposing the plant tip called the ‘shoot apical meristem’, which gives rise to all the aerial parts of the adult plant.
• It is important ....
