Upregulation of genes involved in DNA damage repair and sperm cell differentiation leads to restoration of pollen viability in synthetic allotetraploid B. carinata after chromosome doubling. Apart from the well-known contribution of polyploidy to crop improvement, polyploids can also be induced for other purposes, such as to restore the viability of sterile hybrids.

- Scientists studied a type of plant called Brassica juncea hybrids and found that problems with their chromosomes and cell processes made the pollen not work properly, which is called pollen abortion.
- They discovered that some important genes that help with pollen and sperm cell development were less active, leading to issues during the plant's growth.
- The study helped reveal how these problems happen in the plant's cells and why the pollen doesn't form correctly in the hybrid plants.
Polyploidy plays a crucial role in plant evolution and speciation. The development of male and female gametes is essential to the reproductive capacity of polyploids, but their gene expression pattern has not been fully explored in newly established polyploids. The present study aimed to reveal a detailed atlas of gene expression for gamete development in newly synthetic allohexaploids that are not naturally existing species.
