A study published in the Plant Biotechnology Journal shows that the knockout
of ZmPRR37-CR resulted in the early flowering of maize. The study also found
that the ZmPRR37 gene can potentially enhance salt stress tolerance in

Flowering is a crucial stage in plant reproductive development. However, it
can be affected by various environmental factors, which can either delay or
accelerate the flowering of plants. As a short-day plant, flowering of maize
in long-day environments has been challenging. Hence, the researchers
analyzed and edited the genes of maize to induce flowering and improve salt

The study revealed that the ZmPRR37 gene causes delays in the flowering of
maize under long-day conditions. The findings of the study provide
significant insights into the crucial role of ZmPRR37 in regulating
flowering time and salt stress response in maize.
