The macronutrient potassium (K) is essential to plant growth and development. Crop yield potential is often affected by lack of soluble K. The molecular regulation mechanism of physiological and biochemical responses to K starvation in soybean roots and shoots is not fully understood. In the present study, two soybean varieties were subjected to low-K(More)
MicroRNAs (miRNAs) are endogenous small RNAs regulating plant development and stress responses. In addition, phosphorus (P) is an important macronutrient for plant growth and development. More than two hundred miRNAs have been identified in Glycine Max and a few of miRNAs have been shown to respond to P deficiency, however, whether there are other miRNAs(More)
The root nodule symbiosis (RNS) between legume plants and rhizobia is the most efficient and productive source of nitrogen fixation, and has critical importance in agriculture and mesology. Soybean (Glycine max), one of the most important legume crops in the world, establishes a nitrogen-fixing symbiosis with different types of rhizobia, and the efficiency(More)
Soybean is an important oil and protein crop in the world. Cotton bollworm (Helicoverpa armigera) is one of primary defoliating insects which seriously damage the soybean production. The wild soybean, ED059, was reported to be highly resistant to H. armigera. However, the molecular mechanism of resistance to H. armigera remains unknown. In this study, we(More)
Nodulation, nodule development and senescence directly affects nitrogen fixation efficiency, and previous studies have shown that inhibition of some cysteine proteases delay nodule senescence, so their nature inhibitors, cystatin genes, are very important in nodulation, nodule development, and senescence. Although several cystatins are actively transcribed(More)
Patellin1 (PATL1) is a plant Sec14-related protein, and several PATL proteins have been discovered in Arabidopsis and zucchini (Cucurbita pepo). However, little knowledge is gained about PATL proteins for crop plants. In this study, we identified seven PATL-like proteins (GmPATL) from soybean (Glycine max). These GmPATL proteins share the typical structure(More)
GATA transcription factors are transcriptional regulatory proteins that contain a characteristic type-IV zinc finger DNA-binding domain and recognize the conserved GATA motif in the promoter sequence of target genes. Previous studies demonstrated that plant GATA factors possess critical functions in developmental control and responses to the environment. To(More)
In this study, Rpp6907, a novel resistance gene/allele to Phakopsora pachyrhizi in soybean, was mapped in a 111.9-kb region, including three NBS-LRR type predicted genes, on chromosome 18. Soybean rust caused by Phakopsora pachyrhizi Sydow has been reported in numerous soybean-growing regions worldwide. The development of rust-resistant varieties is the(More)
