“…The Zm00001d003257 gene encodes the 26 S proteasome regulatory subunit Rpn7/COP9 signaling complex subunit 1. This gene has been shown to upregulate or downregulate gibberellins (GAs) in rice in response to external stresses [ 25 ], playing a crucial role in plant growth and development, and immune responses. Both endogenous and exogenous GAs have been found to induce disease resistance and susceptibility in rice against different pathogens [ 26 ].…”

Background Understanding the genetic mechanisms underlying gray leaf spot (GLS) resistance in maize is crucial for breeding GLS-resistant inbred lines and commercial hybrids. Genome-wide association studies (GWAS) and gene functional annotation are valuable methods for identifying potential SNPs (single nucleotide polymorphism) and candidate genes associated with GLS resistance in maize. Results In this study, a total of 757 lines from five recombinant inbred line (RIL) populations of maize at the F7 generation were used to construct an association mapping panel. SNPs obtained through genotyping-by-sequencing (GBS) were used to perform GWAS for GLS resistance using a linear mixture model in GEMMA. Candidate gene screening was performed by analyzing the 10 kb region upstream and downstream of the significantly associated SNPs linked to GLS resistance. Through GWAS analysis of multi-location phenotypic data, we identified ten candidate genes that were consistently detected in two locations or from one location along with best linear unbiased estimates (BLUE). One of these candidate genes, Zm00001d003257 that might impact GLS resistance by regulating gibberellin content, was further identified through haplotype-based association analysis, candidate gene expression analysis, and previous reports. Conclusions The discovery of the novel candidate gene provides valuable genomic resources for elucidating the genetic mechanisms underlying GLS resistance in maize. Additionally, these findings will contribute to the development of new genetic resources by utilizing molecular markers to facilitate the genetic improvement and breeding of maize for GLS resistance.

“…RT-qPCR was used to analyze the expression of eight OsCSN genes in 14-day-old rice seedlings. The results showed that the expression of these eight OsCSN genes was significantly reduced after GA treatment, and the transcript level of OsCSN1 was slightly increased after ABA treatment [23]. These results suggest that OsCSN genes may respond to plant hormones and perform different functions [23].…”

These results suggest that OsCSN genes may respond to plant hormones and perform different functions [23]. The length of the CSN1 homologous gene in rice is the same as that in Arabidopsis, with a total 441 amino acids of CSN1, and the amino acid sequence homology with AtCSN1 is 67% [24].…”

OsCSN1 Regulates the Growth and Development of Rice Seedlings through the Degradation of SLR1 in the GA Signaling Pathway

The constitutive photomorphogenesis 9 (COP9) signalosome (CSN) is involved in various regulations during plant development. The CSN is a highly conserved protein complex with nine subunits, and CSN1 acts in a network of signaling pathways critical for plant development. Although CSN1 has been widely studied in Arabidopsis thaliana, there have been few investigations on CSN1 in rice. In this paper, using the CRISPR/Cas9 system, CSN1 was edited from Oryza sativa subsp. japonica (rice). After screening out the OsCSN1 knockout mutant and OsCSN1 reduce mutant, the phenotype and protein expression were identified under different light conditions. Experiments showed that in OsCSN1 knockout mutant and OsCSN1 reduce mutant, the SLR1 protein was rapidly degraded at the rice seedling. In this study, the OsCSN1 acted as a negative regulator to affect seedling growth and development through CUL4-based E3 ligase, which is involved in the degradation of SLR1 in the GA signaling pathway. However, its direct target and mechanism of action are not clear.
