Comparative transcriptome analysis of manganese transportation in different leaves in soybean under manganese stress

Project description:Manganese (Mn) stress is known to be a major limitation for development of soybean, and legume crop productivity globally. However, very little information is available on the adaptive mechanisms, particularly in the important legume crop soybean (Glycine Max L.), which enable leaves to respond to high-Mn availability. Thus, to elucidate these mechanisms in soybean leaves at molecular level, we used an RNA sequencing approach to investigate transcriptomes of the leaves under Mn-sufficient and Pi-excessive conditions. Our investigation revealed that more genes showed altered expression patterns in old leaf than in young leaf under Mn excess, suggesting that the Mn excess-more-sensitive old leaf required expression change in a larger number of genes to cope with high-Mn stress than the Mn excess-less-sensitive young leaf. The functional classification of differentially expressed genes (DEGs) was examined to gain an understanding of how leaves respond to Mn stress, caused by soil Mn excess. As a result, more DEGs involved in nodulation, detoxification, nutrient/ion transport, transcriptional factors, key metabolic pathways, Mn remobilization and signalling were found in Mn-excessive induced old leaves than in Mn-excessive induced young leaves. Our findings have enabled the identification of molecular processes that play important roles in the acclimation of leaves to Mn excess, ultimately leading to the development of Mn-efficient soybean suitable for Mn-excessive soils.

Quantitative proteomics analysis of soybean leaves under low and high phosphate conditions

Project description:Low phosphate (LP) availability is a critical limiting factor affecting soybean production. Soybean plants develop a series of strategies to adapt phosphate limitation condition. To know the underlying molecular mechanisms responsible for LP stress response. A label-free quantification (LFQ) analysis of soybean leaves grown under low and high phosphate condition was performed.

RNAseq data of two week-old soybean leaves response to cold stress

Project description:Transcriptome analysis of cold-treated leaves (unifoliates) of soybean seedlings were performed. RNAseq analysis was performed using two lanes on a Illumina HiSeq2000 and sequenced on a 100bp, paired-end run.

Decoding the global transcriptomic profile under extreme manganese toxicity

Project description:To achieve extreme manganese stress, we used DmntP E. coli strain. We identified the pathways that are altered under manganese stress. Mainly, manganese altered the metabolism of iron in the cell. Therefore, we have shown that iron supplementation mitigates manganese toxicity. Overall, our data explains the basis of manganism in higher organisms.

Expression data from Soybean leaves under drought stress and normally irrigated

Project description:BiP overexpression confers resistance to drought, through an as yet unknown mechanism that is related to ER functioning, has been described that the delay in leaf senescence by BiP overexpression might relate to the absence of the response to drought. We used microarrays to detail the global programme of gene expression underlying in soybean leaves overexpressing BiP and with different water potentials to elucidate the mechanisms by which BiP protects plant cells against cell death induced by dehydration. BiP overexpressing plants and wild type as a control were subjected to dry slowly for 25 days. Third or fourth trifoliate leaves were collected from plants in water potential next 1.0 MPa, 1.5 MPa and 1.7 MPa for test weak and strong stress and subject RNA extraction and hybridization on Affymetrix microarrays maintaining the hybridization of two chips per treatment.

Transcriptomics Analyses of soybean leaves and roots sample during water-deficit

Project description:Microarray experiments were performed on the roots and leaves samples seperately using custom based Nimblgen platform (12plex). This is a time-course study. The plants were grown in controlled growth chamber condiditons ambiient to soybean growth and development using a hydrophonics system. The tissues were harvested after 30days of growth in six time points- 0min, 30mins, 1hour, 2hours, 3hours and 5hours of dehydration.

Complex regulatory mechanisms underlying mineral nutrient acquisition in soybean roots responsive to low pH stress

Project description:Proton toxicity is one of the major environmental stresses limiting crop production, and becomes increasingly serious because of anthropogenic activities. To understand acid tolerance mechanisms, the plant growth, mineral nutrient accumulation and global transcriptome changes in soybean (Glycine max) in response to long-term acid stress were investigated. Results showed that acid stress significantly inhibited soybean root growth, but exhibited slight effects on the shoot growth. Moreover, concentrations of essential mineral nutrients were significantly affected by acid stress, mainly dependent on soybean organs and mineral nutrient types. The concentrations of phosphorus (P) and molybdenum (Mo) in both leaves and roots, nitrogen (N) and potassium (K) in roots and magnesium (Mg) in leaves were significantly decreased, respectively. Whereas, the concentrations of calcium (Ca), sulfate (S) and iron (Fe) were increased in both leaves and roots. Transcriptome analyses in soybean roots resulted in identifying 419 up-regulated and 555 down-regulated genes under acid conditions. A total of 38 differentially expressed genes (DEGs) were involved in mineral nutrient transportation. Among them, all the detected five GmPTs and GmZIPs, two GmAMTs and GmKUP genes, together with GmIRT1, GmNramp5, GmVIT2.1, GmSKOR, GmTPK5 and GmHKT1, were significantly suppressed. Moreover, the genes encoding transcription factors (e.g., GmSTOP2s and a GmPHL1), and genes involved in pH stat metabolic pathways were significantly up-regulated by low pH stress in soybean roots. Taken together, it strongly suggested that maintaining pH stat and mineral nutrient homeostasis are adaptive strategies of soybean responses to acid stress, which might be regulated by a complex signaling network.
