Crop Improvement
Understanding how rice pollen works at the genetic level could help breeders develop more reliably fertile rice varieties, protecting yields for the billions of people who depend on rice as a staple food.
For a rice plant to make seeds, its pollen has to sprout and grow a tiny tube to reach the egg. Researchers found a group of genes that help control this process. By studying these genes, scientists are learning what makes rice reproduction work — and what could go wrong in heat, drought, or other stressful conditions.
Key Findings
A family of OsENTH genes was comprehensively identified and catalogued in the rice genome.
Functional characterization confirmed that OsENTH genes play active roles in pollen germination and pollen tube growth.
The study provides a genetic foundation for future work on improving rice fertility and seed set under variable conditions.

Scientists identified and studied a family of genes in rice called OsENTH that play a role in pollen germination and pollen tube growth — the process by which rice fertilizes itself to produce grain.

Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
