Comparative Analysis Highlights Uniconazole’s Efficacy in Enhancing the Cold Stress Tolerance of Mung Beans by Targeting Photosynthetic Pathways

Project description:Soybean (Glycine max) and mung bean (Vigna radiata) are key legumes with global importance, but their mechanisms for coping with cold stress—a major challenge in agriculture—have not been thoroughly investigated, especially in a comparative study. This research aimed to fill this gap by examining how these two major legumes respond differently to cold stress and exploring the role of uniconazole, a potential stress mitigator. Our comprehensive approach involved transcriptomic and metabolomic analyses, revealing distinct responses between soybean and mung bean under cold stress conditions. Notably, uniconazole was found to significantly enhance cold tolerance in mung bean by upregulating genes associated with photosynthesis, while its impact on soybean was either negligible or adverse. To further understand the molecular interactions, we utilized advanced machine learning algorithms for protein structure prediction, focusing on photosynthetic pathways. This enabled us to identify LOC106780309 as a direct binding target for uniconazole, confirmed through isothermal titration calorimetry. This research establishes a new comparative approach to explore how soybean and mung bean adapt to cold stress, offers key insights to improve the hardiness of legumes against environmental challenges, and contributes to sustainable agricultural practices and food security.

Rhizobia Contribute to Salinity Tolerance in Common Beans ( Phaseolus vulgaris L.)

Project description:Rhizobia are soil bacteria that induce nodule formation on leguminous plants. In the nodules, they reduce dinitrogen to ammonium that can be utilized by plants. Besides nitrogen fixation, rhizobia have other symbiotic functions in plants including phosphorus and iron mobilization and protection of the plants against various abiotic stresses including salinity. Worldwide, about 20% of cultivable and 33% of irrigation land is saline, and it is estimated that around 50% of the arable land will be saline by 2050. Salinity inhibits plant growth and development, results in senescence, and ultimately plant death. The purpose of this study was to investigate how rhizobia, isolated from Kenyan soils, relieve common beans from salinity stress. The yield loss of common bean plants, which were either not inoculated or inoculated with the commercial R. tropici rhizobia CIAT899 was reduced by 73% when the plants were exposed to 300 mM NaCl, while only 60% yield loss was observed after inoculation with a novel indigenous isolate from Kenyan soil, named S3. Expression profiles showed that genes involved in the transport of mineral ions (such as K+, Ca2+, Fe3+, PO43-, and NO3-) to the host plant, and for the synthesis and transport of osmotolerance molecules (soluble carbohydrates, amino acids, and nucleotides) are highly expressed in S3 bacteroids during salt stress than in the controls. Furthermore, genes for the synthesis and transport of glutathione and γ-aminobutyric acid were upregulated in salt-stressed and S3-inocculated common bean plants. We conclude that microbial osmolytes, mineral ions, and antioxidant molecules from rhizobia enhance salt tolerance in common beans.

Expression data from different photosynthetic rate in Populus.

Project description:Despite the significance of nucleus genes in plant growth and development, little is known of the molecular bases of regulation of photosynthesis in woody plants.Hence discovering the genetic basis for photosynthesis related phenotypic variation and identifying the major genes controlling these complex traits in trees is essential. Combining the microarray technique and bulked segregant analysis strategy, we used poplar as a model to detect the nucleus genes differentially expressed in segregation population of photosynthesis traits. We measured the F1 interspecific population and segregated the stable extrem samples into two groups including three pools containing five incividuals.Use the Affymetrix poplar gene chip to decrypt the gene functions and mechanisms in different photosynthetic rate. Leaves were taken from high and low photosynthetic rate individuals for RNA extraction and hybridization on Affymetrix microarrays. H_A, H_B, H_C are from the high photosynthetic rate individuals. L_D,L_E, L_F are from the low photosynthetic rate incividuals.

Genetic Dissection of Photosynthetic Organs Contribution to Seed Oil Accumulation in Arabidopsis seeds

Project description:We report the application of RNA-seq technology for highthroughput profiling of photosynthetic and non-photosynthetic seeds of Arabidopsis chlorophyll synthase mutant seeds. By generating over 21 GB of sequence data from these seeds, we showed that genes involved in oil accumulation in non-photosynthetic seeds were significantly induced compared to photosynthtic seeds. Additionally we found that genes involved in the plastidal oxidative pentos phosphate pathway were significantly upregulated in the non-photosynthetic seed opposite to photosynthetic seeds. Overall our RNA-seq analysis revealled the genes and pathway interaction underpinining oil accumulation in non-photosynthetic seeds.

Proteomic and peptidomic UHPLC-ESIProteomic and peptidomic UHPLC-ESI MS/MS analysis of cocoa beans fermented using the Styrofoam box method MS/MS analysis of cocoa beans fermented using the Styrofoam box method

Project description:Fermentation is essential for cocoa flavour development, as during this process key flavour precursors are formed from the degradation of the major cocoa bean storage proteins. This work characterises the peptide and protein profiles of Theobroma cacao beans of the genotype IMC 67 at different fermentation stages, using the Styrofoam box fermentation method and employing UHPLC-ESI MS/MS for the analysis of peptides and proteins extracted from the beans. A total of 1058 endogenous peptides were identified and quantified over four fermentation time points. The majority of these peptides were formed during the early stage of fermentation and originated predominantly from the proteolysis of two storage proteins - vicilin and a 21 kDa albumin. The changes in the peptide profile over fermentation were subsequently evaluated, and potential markers for assessing the degree of fermentation were identified. In particular, changes of the relative abundance of the major cocoa proteins detected can be proposed as potential markers for the fermentation stage. Furthermore, PCA analysis of both the peptidomic and proteomic data has allowed differentiation of beans at different fermentation stages.
