144 prioritized genes of flooding-tolerance (FTgenes) in soybean

<p><span>Soybean [</span><em>Glycine max</em><span> (L.) Merr.] is one of the most important legume crops abundant in edible protein and oil in the world. Due to the drastic climate change, flooding, drought and unevenly distributed rainfall have gradually increased in terms of the frequency and intensity worldwide. In particular, severe flooding has caused extensive losses to soybean production. In light of the harsh situation, there has been an urge to breed strong soybean seeds with high flooding tolerance. We collected and integrated genetic data that relevant to flooding-tolerant responses in soybean from </span>multiple dimensional data sources. A step-function adjusted factor prioritization algorithm was proposed to prioritize these integrated genetic data. A total of 144 candidate genes of flooding-tolerance (FTgenes) in soybean were <span>prioritized, </span>using a cut-off threshold of combined score of 42,<span> from 36,705 test genes that collected from multidimensional genomic features linking to soybean flooding tolerance</span>. <span>Several validation results using independent samples from SoyNet, GWAS, SoyBase, </span><span>GO database</span><span> and transcriptome databases all exhibited excellent agreement, suggesting these 144 FTgenes were significantly superior than others.</span><span> </span><span>Our results provide valuable information, meaningful insight, and contribution to varieties selection of soybean</span><span>. The FTgenes demonstrated the potential for uncovering important insights underlying flooding-tolerant response in soybean in systems biology stuydies.</span></p>
