This study delves into the combined effects of seasonal climate variations and MIPS1 gene mutations on the germination rates of soybean cultivars TW-1 and TW75. Through comprehensive metabolomic and transcriptomic analyses, we identified key KEGG pathways significantly affected by these factors, including starch and sucrose metabolism, lipid metabolism, and amino acid biosynthesis. These pathways were notably disrupted during the spring, leading to an imbalance in metabolic reserves critical for seedling development. Additionally, MIPS1 gene mutations further altered these pathways, exacerbating the metabolic disturbances. Our results underscore the intricate network of environmental and genetic interactions influencing soybean seed vigor and underscore the importance of understanding these pathways to enhance agricultural resilience and seed quality in fluctuating climates.
本研究深入探讨了季节性气候变化和MIPS1基因突变对大豆品种TW - 1和TW75发芽率的综合影响。通过全面的代谢组学和转录组学分析，我们确定了受这些因素显著影响的关键KEGG途径，包括淀粉和蔗糖代谢、脂质代谢以及氨基酸生物合成。这些途径在春季明显受到干扰，导致对幼苗发育至关重要的代谢储备失衡。此外，MIPS1基因突变进一步改变了这些途径，加剧了代谢紊乱。我们的结果强调了影响大豆种子活力的环境和基因相互作用的复杂网络，并强调了理解这些途径对于在气候变化波动的情况下提高农业抗逆性和种子质量的重要性。
