Genetic regulatory networks of soybean seed size, oil
The oil content of soybean seeds ranges from 8.3 to 27.9%, and protein concentration varies from 34.1 to 56.8% depending on the soybean varieties and cultivation conditions (Wilson, 2004). Soybean oil is generated and stored mainly as fatty acids (FAs), triacylglycerols (TAGs), and tocopherols (Liu et al., 2022).
GWAS identified a major locus controlling soybean seed oil content on chromosome 5. Previously, we mapped a major QTL (qOil-5-1) controlling seed oil content into a 2.17 Mb region at the end of chromosome 5 using the RIL population derived from Huachun 2 and Wayao (Huang et al., 2020). This QTL has been stably detected in multiple seasons and
Integrative omics analysis elucidates the genetic basis
There were no significant variations in plant architecture and seed number per plant between OX1/2 and wild type (Supplementary Fig. S11, D and E). These findings suggest that GmRWOS1 negatively regulates seed weight and oil content in soybean. Selection of GmRWOS1 during soybean domestication
To further compare the relative expression levels of candidate genes in soybean accessions with different seed oil content, seeds were harvested at 10, 20, 30 and 40 d after flowering (DAF) from Jindou20 (24.08% oil content) and Maliaodou (17.53% oil content) for RNA-isolation and quantitative real time (qRT-)PCR analysis.
Quantitative trait loci analysis of seed oil content
Background Soybean oil is a major source of edible oil, and the domestication of wild soybean has resulted in significant changes in oil content and composition. Extensive efforts have been made to identify genetic loci that are related to soybean oil traits. The objective of this study was to identify quantitative trait loci (QTLs) related to soybean seed oil and compare the fatty acid
Soybean is an important oilseed crop which supplies both industrial processes and animal feed as well as having a number of food uses. The high yields of oil from soybean seed, along with large planting acreage, significant production infrastructure, and its capacity to fix nitrogen, make it the second most valuable crop in the USA and fourth in the world. In this review, we discuss the
Integrative omics analysis elucidates the genetic basis
Notably, allelic variations of GmRWOS1 were strongly selected during domestication of soybean. This study uncovers the genetic basis and network underlying regulation of seed weight and oil content in soybean and provides a valuable resource for improving soybean yield and quality by molecular breeding.
The oxidative stability index, broadly defined as the length of time before the onset of oxidation of an oil, is 8.9, 5.4, 22.7, and 16.7 h for ultra-low-lin, standard soybean oil, partially hydrogenated soybean oil, and high oleic acid (>80%) sunflower (Helianthus annuus) oil, respectively (Warner, 2009). Oils with a high percentage of oleic
QTL mapping of seed protein and oil traits in two recombinant
Soybean seed protein and oil are valuable traits because of the extensive use of soybean in the production of vegetable oil and meal. In 2019, soybean accounted for 59% of the total oilseed production worldwide and 56% of the total vegetable oil consumption in the USA (ASA Citation 2019).
Seed oil content is one of the most important quantitative traits in soybean (Glycine max) breeding. Here, we constructed a high-density single nucleotide polymorphism linkage map using two genetically similar parents, Heinong 84 and Kenfeng 17, that differ dramatically in their seed oil contents, and performed quantitative trait loci (QTL) mapping of seed oil content in a recombinant inbred
- How many QTLs control soybean seed oil and protein content?
- Nowadays, over 700 QTLs controlling soybean seed oil and protein contents have been identified using accessions with different genetic backgrounds, and 57 QTLs have been confirmed (Van & McHale, 2017).
- What is the molecular mechanism of cottonseed oil accumulation?
- The molecular mechanism of cottonseed oil accumulation remains unclear. In the present study, we conducted comparative transcriptome and weighted gene co-expression network (WGCNA) analysis for two G. hirsutum materials with significant difference in cottonseed oil content.
- How to improve soybean seed oil content?
- There are two major goals in improving the soybean seed oil content. The first is to increase the total oil content of the seed, ideally without sacrificing the overall yield. The second is to ¡°improve¡± the oil quality by increasing the beneficial fatty acids while reducing those detrimental ones.
- Does soybean protein content affect seed oil content?
- However, the negative correlations in soybean seeds between protein content and oil content as well as yield render it challenging to increase soybean protein content while maintaining the desired seed oil level and seed yield (Patil et al., 2017; Rincker et al., 2014).
