“…Without further research to understand the impact of each identified candidate gene individually, it is difficult to model what is likely to be complex interactions of these genes in relation to photoperiod response. Recent work established a regulatory link between the GmTEM1a ortholog, GmTEM1b (GmRAV), and several gibberellins-associated genes in the modulation of plant height in soybean (Xue et al, 2022). It would be interesting to investigate whether there is a similar link between the GmTEM1a, GmGA2OX5, and GmGA2OX6 genes identified in this study in the control of flowering.…”

Candidate Genes Modulating Reproductive Timing in Elite US Soybean Lines Identified in Soybean Alleles of Arabidopsis Flowering Orthologs With Divergent Latitude Distribution

et al. 2022

Adaptation of soybean cultivars to the photoperiod in which they are grown is critical for optimizing plant yield. However, despite its importance, only the major loci conferring variation in flowering time and maturity of US soybean have been isolated. By contrast, over 200 genes contributing to floral induction in the model organism Arabidopsis thaliana have been described. In this work, putative alleles of a library of soybean orthologs of these Arabidopsis flowering genes were tested for their latitudinal distribution among elite US soybean lines developed in the United States. Furthermore, variants comprising the alleles of genes with significant differences in latitudinal distribution were assessed for amino acid conservation across disparate genera to infer their impact on gene function. From these efforts, several candidate genes from various biological pathways were identified that are likely being exploited toward adaptation of US soybean to various maturity groups.

“…A few mutants of the AP2 genes have been reported as candidate genes of dwarf plants, such as ddf1 in Arabidopsis ( Magome et al., 2004 ), ndl1 in rice ( Kusnandar et al., 2022 ), and dil1 in maize ( Jiang et al., 2012 ). AP2 genes have been reported to play a significant role in GA signaling pathways, which are involved in the growth and development of plants ( Magome et al., 2004 ; Xue et al., 2022 ). In a previous study, Zhang778 was proven to be caused by a mutation of the genes related to GA synthesis ( Zhang et al., 2020 ), which is consistent with the function of AP2 genes.…”

The plant height of broomcorn millet (Panicum miliaceum) is a significant agronomic trait that is closely related to its plant architecture, lodging resistance, and final yield. However, the genes underlying the regulation of plant height in broomcorn millet are rarely reported. Here, an F2 population derived from a cross between a normal variety, “Longmi12,” and a dwarf mutant, “Zhang778,” was constructed. Genetic analysis for the F2 and F2:3 populations revealed that the plant height was controlled by more than one locus. A major quantitative trait locus (QTL), PH1.1, was preliminarily identified in chromosome 1 using bulked segregant analysis sequencing (BSA-seq). PH1.1 was fine-mapped to a 109-kb genomic region with 15 genes using a high-density map. Among them, longmi011482 and longmi011489, containing nonsynonymous variations in their coding regions, and longmi011496, covering multiple insertion/deletion sequences in the promoter regions, may be possible candidate genes for PH1.1. Three diagnostic markers closely linked to PH1.1 were developed to validate the PH1.1 region in broomcorn millet germplasm. These findings laid the foundation for further understanding of the molecular mechanism of plant height regulation in broomcorn millet and are also beneficial to the breeding program for developing new varieties with optimal height.

“…Consistent with the nding in rice, GA plays a vital role in soybean plant height. A number of genes involved in GA biosynthesis or signaling pathways have been reported to regulate soybean height, such as GmDW1 (Dwarf Mutant 1) (Li et al 2018b), GmAP1s (Apetala1) (Chen et al 2020), and GmLHY (Late elongated hypocotyl) (Cheng et al 2019), ABI3/VP1 gene GmRAV (Xue et al 2022). It is well known that auxin promotes GA biosynthesis (Wolbang and Ross 2001;Ross et al 2000;Ross et al 2001).…”

Breeding crop varieties with high-yield and ideal plant architecture is a desirable goal of agricultural science. The success of 'Green Revolution' in cereal crops provides opportunities to incorporate phytohormones in crop breeding. Auxin is a critical phytohormone to determinate nearly all the aspects of plant development. Despite the current knowledge regarding auxin biosynthesis, auxin transport and auxin signaling has been well characterized in model Arabidopsis plants, how auxin regulates crop architecture is far from being understood and the introduction of auxin biology in crop breeding stays in the theoretical stage. Here, we give an overview on molecular mechanisms of auxin biology in Arabidopsis, and mainly summarize auxin contributions for crop plant development. Furthermore, we propose potential opportunities to integrate auxin biology in soybean breeding. Full TextTo meet human demand for food, the 'Green Revolution' in agriculture has saved more than a billion people from starvation in 1960s. The 'Green Revolution' refers to the modi cation of cereal crop architecture, like rice and wheat, from tall to short and compact plants which are suitable for high-density planting with high-yielding per acre (
