Genome-Wide Analysis of the <i>RbcS</i> Gene Family and Expression Analysis Under Light Response in <i>Brassica napus</i> L.

ABSTRACT: Enhancing photosynthetic efficiency represents a key approach for improving crop biomass, with its translation into higher grain yield being contingent upon the efficiency of photosynthate partitioning toward harvestable organs. The Rubisco small subunit (RbcS) gene family plays an essential role in this process by stabilizing and regulating Rubisco assembly and activity during photosynthesis. In this study, we identified 61 RbcS genes across B. napus, B. juncea, and B. carinata, and their diploid progenitors B. rapa, B. nigra, and B. oleracea by genome-wide screening and bioinformatic approaches.
