Project description:In the study, two soybean genotypes were selected to conduct high and low P, high and low Mg, and AM fungal inoculation treatments, combined with RNA-seq sequencing technique in order to investigate the physiological and molecular mechanisms of the symbiosis between soybean and AM fungi affected by P and Mg treatments. The results showed that both Mg application and AM fungal inoculation were beneficial to promote soybean growth under low P condition. And there was a synergistic effect between the Mg concentration and the P concentration in the root of HN112 under the inoculation condition. RNA-seq sequencing was carried out using the roots of P-efficient soybean HN89 under different Mg and inoculation treatments with low P condition, and the difference of gene expression profiles was analyzed between high and low Mg treatments, and different inoculation treatments. According to the analysis of GO function classification and KEGG enrichment, under high Mg condition, the metabolic pathway was mainly enriched in lipid metabolism and glucose metabolism pathway under the inoculation treatment compared with the non-inoculation treatment, which regulated carbon metabolism pathway. Under the low Mg condition, the metabolic pathway was mainly enriched in the photosynthesis- antenna protein pathway to regulate the photosynthesis pathway under the inoculation treatment compared with the non-inoculation treatment. At the same time, the inoculation treatment significantly increased soybean root starch concentration under low Mg condition, compared with the non-inoculation treatment, suggesting that the significant up-regulation of a large number of photosynthesis related genes might be related to the significant increase of starch concentration at this treatment.

Project description:As an important adaptation to drought stress, several agronomic species, such as soybean and maize, can maintain the primary root substantial elongation rates at low water potentials, whereas shoot growth stops completely. In soybean, kinematic characterization of the spatial patterns of cell expansion within the root elongation zone showed that at low water potentials, elongation rates were preferentially maintained toward the root apex but were progressively inhibited at more basal locations, resulting in a shortened growth zone. To explore the molecular mechanism of root elongation in response to water stress, we set out to examine the expression of soybean genes in different root regions after 5 hours (5h) and 48 hours (48h) water stress treatment using the Affymetrix Soybean GeneChip containing 37,500 G. max probe sets.

Project description:Increased root H+ secretion is known as a strategy of plant adaption to low phosphorus (P) stress by enhancing mobilization of sparingly soluble P-sources. However, it remains fragmentarywhether enhanced H+ exudation could reconstruct the plant rhizosphere microbial community under low P stress. The present study found that P deficiency led to enhanced H+ exudation from soybean (Glycine max) roots. Three out of all eleven soybean H+-pyrophosphatases (GmVP) geneswere up-regulated by Pi starvation in soybean roots. Among them, GmVP2 showed the highest expression level under low P conditions. Transient expression of a GmVP2-green fluorescent protein chimera in tobacco (Nicotiana tabacum) leaves, and functional characterization of GmVP2 in transgenic soybean hairy roots demonstrated that GmVP2 encoded a plasma membrane transporter that mediated H+ exudation. Meanwhile, GmVP2-overexpression in Arabidopsis thaliana resulted in enhanced root H+ exudation, promoted plant growth, and improved sparingly soluble Ca-P utilization. Overexpression of GmVP2 also changed the rhizospheric microbial community structures, as reflected by a preferential accumulation of acidobacteria in the rhizosphere soils. These results suggested that GmVP2 mediated Pi-starvation responsive H+ exudation,which is not only involved in plant growth and mobilization of sparingly soluble P-sources, but also affects microbial community structures in soils.

Project description:Brassinosteroids (BRs) are a series of sterol hormones in plants, which play important physiological roles in many aspects of plant growth and development processes. Exogenous application of BR and its inhibitors PPZ to investigated the roles of BR in soybean root growth and development. Transcriptome sequencing analysis was performed to identified lots number of differential expression genes(DEGs) by eBL (2,4-epicastasterone, 24-epiCS) and PPZ (propiconazole) treatment of soybean root tips(1 cm).

Project description:The regulatory effects of uneven phosphorus supplies on phosphorus transport in soybean roots is still unclear. To further analyze the regulatory effects of low-phosphorus stress on phosphorus transport in soybean roots and the effects of uneven phosphorus application on the physiological mechanism of phosphorus transport in soybean roots, dual-root soybean plants were prepared via grafting, and a sand culture experiment was performed.

Project description:Gene expression profiling in soybean under aluminum stress: Transcriptome response to Al stress in roots of Al-tolerant genotype (PI 416937). Aluminum (Al) toxicity is a major constraint of crop production on acid soils. Many commercial soybean cultivars and advanced breeding lines have been evaluated for Al tolerance. Aluminum tolerance is quantitatively inherited trait in soybean making it difficult for genetic improvement. Understanding the molecular and genetic mechanisms of tolerance is crucial for developing efficient and effective programs aimed at improving Al tolerance trait The molecular mechanisms of Al tolerance is poorly understood in soybean. The objective of the research was to identify candidate aluminum tolerance genes in soybean Al-tolerant soybean genotype PI 416937 seedlings were exposed to zero or 10 µM Al in growth chamber under hydroponic conditions for four time span of 2, 12, 48 and 72 hrs in a randomized complete block design with three replications. Microarray analysis was made on mRNA isolated from 1 cm log tap root tips using Affymetrix soybean array with over 68,000 probe sets Glycine max L and wild soybean combined. Both novel and known genes were discovered in response to Al treatment. They include Al tolerance relevant proteins, families of transcription factors, zinc finger, bZIP, WRKY, MYB, ADR6, and NAC domain proteins were induced likely regulating Al tolerance downstream genes. Stress related proteins, cytochrome P450, glutathione-s transferase, glutaredoxin family and ascorbic acid biosynthesis protein were induced as signatures of cellular detoxification mechanisms. An ABC type multidrug resistance protein that could act as citrate transporter or Al exporter was up-regulated, a key Al tolerance mechanisms in several species. A cell wall loosening enzyme endoxylglucan hydrolases were also up-regulated probably reversing the wall rigidification caused by Al and promoting root growth under Al stress. Phytosulfokines growth factor involved in cell division and proliferation was up-regulated likely as a direct counter action to Al toxicity which inhibits root growth by limiting cell division and elongation. In conclusion, the Al tolerance candidate genes identified herein are potential targets for future genetic engineering and molecular breeding work on Al tolerance trait in soybean which in turn would contribute to gain in soybean productivity on acid soils.
