Rice breeding in the new era: comparison of useful agronomic traits

Abstract

Understanding agronomic traits at a genetic level enables the leveraging of this knowledge to produce crops that are more productive and resilient, have better quality and are adjusted for consumer preferences. In the last decade, rice has become a model to validate the function of specific genes, resulting in valuable but scattered information. Here, we aimed to identify particular genes in rice related to traits that can be targeted by different mutation techniques in the breeding of crops. We selected gain of function, misfunction, and specific mutations associated with phenotypes of agronomic interest. The review includes specific trait-related genes involved in domestication, stress, herbicide tolerance, pathogen resistance, grain number/quality/weight, plant structure, nitrogen use, and others. The information presented can be used for rice, other cereals, and orphan crops to achieve a superior and sustainable production in challenging farming conditions.

Genomic Variation Underlying the Breeding Selection of Quinoa Varieties Longli-4 and CA3-1 in China

“…However, for the specific stop-gain variations of the CA3-1,the AUR62035617 gene with 68.6% sequence identity value against Waxy 1 (WX1) was identified. WX1 is an important agronomic trait-related gene playing a vital role in grain quality, especially for the amylose content of the grains [47]. In the rice, wx1 mutant produces the opaque, semitranslucent, or transparent grains [47].…”
