“…However, overexpressing the gene in the short silique parental line G120 did not have any impact on the phenotype. Further studies revealed that this was due to a single nucleotide deletion in the fifth exon caused a functional alteration in BnC7.ROT3 (Zhou et al, 2022). The number of seeds per silique (NSS) is also a key factor determining overall yield.…”

Brassica napus, commonly known as rapeseed or canola, is a major oil crop contributing over 13% to the stable supply of edible vegetable oil worldwide. Identification and understanding the gene functions in the B. napus genome is crucial for genomic breeding. A group of genes controlling agronomic traits have been successfully cloned through functional genomics studies in B. napus. In this review, we present an overview of the progress made in the functional genomics of B. napus, including the availability of germplasm resources, omics databases and cloned functional genes. Based on the current progress, we also highlight the main challenges and perspectives in this field. The advances in the functional genomics of B. napus contribute to a better understanding of the genetic basis underlying the complex agronomic traits in B. napus and will expedite the breeding of high quality, high resistance and high yield in B. napus varieties.

“…Rapeseed ( Brassica napus L.) is a major oilseed crop and is also used as animal feed and in biodiesel production globally. Developing a high-yielding rapeseed variety has been an important goal to meet the increasing vegetable oil demand 1 , 2 . Rapeseed yield should be improved by increasing the seed number per silique (SPS), which is one of the three direct yield-related components, with the other being silique number and seed weight 3 .…”

“…In another study, BnaC9.SMG7b associated with SPS was identified on chromosome C9 of rapeseed using a map-based cloning strategy 10 . Furthermore, two other major QTL associated with VSL were identified on chromosome C7 ( BnaC7.ROT3 ) and A9 ( BnaA9.CYP78A9 ) of rapeseed and were cloned and characterized using map-based cloning 2 , 9 . Although a few candidate genes for silique traits have been cloned and functionally characterized, key candidate genes for silique traits, especially for SDPS, remain undiscovered.…”

“…Wang et al (2016) 4 obtained 60 consensus QTL for six silique-related traits, including 11 for VSL, 6 for SPS, and 5 for SDPS, by consensus map construction and QTL comparison. Since B. napus has a complex genome, so far only a few QTL associated with SPS or VSL have been mapped or cloned and functionally characterized 2,3,[8][9][10][11] . BnaA.ARF18, the first QTL that affects both seed weight and VSL was identified on chromosome A9 of rapeseed by fine mapping and association analysis 11 .…”

Seed density per silique (SDPS) and valid silique length (VSL) are two important yield-influencing traits in rapeseed. SDPS has a direct or indirect effect on rapeseed yield through its effect on seed per silique. In this study, a quantitative trait locus (QTL) for SDPS was detected on chromosome A09 using the QTL-seq approach and confirmed via linkage analysis in the mapping population obtained from 4263 × 3001 cross. Furthermore, one major QTL for SDPS (qSD.A9-1) was mapped to a 401.8 kb genomic interval between SSR markers Nys9A190 and Nys9A531. In the same genomic region, a QTL (qSL.A9) linked to VSL was also detected. The phenotypic variation of qSD.A9-1 and qSL.A9 was 53.1% and 47.6%, respectively. Results of the additive and dominant effects demonstrated that the expression of genes controlling SDPS and VSL were derived from a different parent in this population. Subsequently, we identified 56 genes that included 45 specific genes with exonic (splicing) variants. Further analysis identified specific genes containing mutations that may be related to seed density as well as silique length. These genes could be used for further studies to understand the details of these traits of rapeseed.

“…The peanut shell is developed from the ovary wall, which protects peanut seeds from biotic and abiotic stresses and continuously provides nutrients for seed development ( Bruce et al, 1975 ). Large shells also provide more environmental space and nutrients for seeds, which are considered a favorable trait for yield improvement ( Zhou et al, 2022 ). The seed develops from double fertilization and seed size is determined when the endosperm cellularization is completed ( Garcia et al, 2003 ).…”

Pod size is one of the most important agronomic features of peanuts, which directly affects peanut yield. Studies on the regulation mechanism underpinning pod size in cultivated peanuts remain hitherto limited compared to model plant systems. To better understand the molecular elements that underpin peanut pod development, we conducted a comprehensive analysis of chronological transcriptomics during pod development in four peanut accessions with similar genetic backgrounds, but varying pod sizes. Several plant transcription factors, phytohormones, and the mitogen-activated protein kinase (MAPK) signaling pathways were significantly enriched among differentially expressed genes (DEGs) at five consecutive developmental stages, revealing an eclectic range of candidate genes, including PNC, YUC, and IAA that regulate auxin synthesis and metabolism, CYCD and CYCU that regulate cell differentiation and proliferation, and GASA that regulates seed size and pod elongation via gibberellin pathway. It is plausible that MPK3 promotes integument cell division and regulates mitotic activity through phosphorylation, and the interactions between these genes form a network of molecular pathways that affect peanut pod size. Furthermore, two variant sites, GCP4 and RPPL1, were identified which are stable at the QTL interval for seed size attributes and function in plant cell tissue microtubule nucleation. These findings may facilitate the identification of candidate genes that regulate pod size and impart yield improvement in cultivated peanuts.
