Gene editing applications to modulate crop flowering time and seed dormancy.

ABSTRACT

Gene editing technologies such as CRISPR/Cas9 have been used to improve many agricultural traits, from disease resistance to grain quality. Now, emerging research has used CRISPR/Cas9 and other gene editing technologies to target plant reproduction, including major areas such as flowering time and seed dormancy. Traits related to these areas have important implications for agriculture, as manipulation of flowering time has multiple applications, including tailoring crops for regional adaptation and improving yield. Moreover, understanding seed dormancy will enable approaches to improve germination upon planting and prevent pre-harvest sprouting. Here, we summarize trends and recent advances in using gene editing to gain a better understanding of plant reproduction and apply the resulting information for crop improvement.
