Project description:Early planting is one of the strategies used to increase grain yield in temperate regions. However, poor cold tolerance in castor inhibits seed germination, resulting in lower seedling emergence and biomass. To date, proteomics studies have identified diverse proteins associated with germinating or developing castor seeds; however, the regulators involved in early imbibed castor seeds under cold stress are rare. Here, the elite castor variety Tongbi 5 was used to identify the differential abundance protein species (DAPS) between cold stress (4 °C) and control conditions (30 °C ) imbibed seeds. As a result, 127 proteins were identified to be differentially accumulated according to iTRAQ strategy. Bioinformatics analyses revealed that 84 DAPS were annotated in 24 GO functional groups, 70 DAPS were classified into 16 COG categories, and 56 DAPS were involved in 16 KEGG pathways. Based on physiological index assays and iTRAQ results, this study provided some invaluable insights into the cold stress responses of early imbibed castor seeds.

Project description:The length of internodes is critical in determining the height of the castor plant (Ricinus communis L.), and is closely associated with internode elongation. However, the exact mechanisms underlying internode elongation, particularly in the main stem of the castor plant, remain uncertain. To investigate further, we conducted a study using the dwarf castor variety 071113, comparing it with the homologous high-stalk Zhuansihao as a control. Our research included cytological observation, physiological measurement, transcriptome sequencing, and metabolic determination. By integrating these findings, we discovered that the dwarf 071113 undergoes earlier main stem lignification development and has a more active lignin synthesis pathway in internode intermediate development. The plant hormone IAA also plays a role in this process. Furthermore, potential enzymes and regulators have been identified, including the auxin influx carrier AUX1 LAX, auxin response protein IAA13, ARF3, auxin-responsive protein SAUR50, peroxidase, and EXPs that regulate cell cycle, cell wall synthesis, as well as growth and development, were also. Based on these findings, we developed a model for castor internode elongation and gained a better understanding of the dwarfing mechanism of the 071113 variety. Our work lays a theoretical foundation for the future breeding of dwarf castor varieties.

Project description:Small noncoding RNA (sncRNA), including microRNAs (miRNAs) and endogenous small-interfering RNAs (endo-siRNAs) are key gene regulators in eukaryotes, playing critical roles in plant development and stress tolerance. Trans-acting siRNAs (ta-siRNAs), which are secondary siRNAs triggered by miRNAs, and siRNAs from natural antisense transcripts (nat-siRNAs) are two well-studied classes of endo-siRNAs. In order to understand sncRNAsM-bM-^@M-^Y roles in plant cold response and stress acclimation, we studied miRNAs and endo-siRNAs in Cassava (Manihot esculenta), a major source of food for the world populations in tropical regions. Combining Next-Generation sequencing and computational and experimental analyses, we profiled and characterized sncRNA species and mRNA genes from the plants that experienced severe and moderate cold stresses, that underwent further severe cold stress after cold acclimation at moderate stress, and that grew under the normal condition. We also included Castor bean (Ricinus communis) to understand conservation of sncRNAs. In addition to known miRNAs, we identified dozens of novel miRNAs as well as ta-siRNA-yielding and nat-siRNA-yielding loci in Cassava and Castor bean, respectively. Among the expressed sncRNAs, many sncRNAs were differentially expressed under cold stresses. Our study provided the results on gene regulation by sncRNAs in cold acclimation of Euphorbiaceous plants and the role of sncRNA-mediated pathways affected by cold stress and stress acclimation in Cassava. Examination of small RNA populations in Cassava cultivar SC124 under the normal condition (NC), gradual cold acclimation (CA), cold shock (CS) and stress acclimation Cold stress after cold acclimation (CCA).

Project description:The aim of the project was to elucidate the inter-organellar interplay of plastids, mitochondria, and peroxisomes during storage reserve mobilization in the endosperm to supply the growing seedling with nutrients upon germination. Organelles from endosperm of etiolated castor bean seedlings were isolated and subjected to liquid chromatography-tandem mass spectrometry. The data were used to build a comprehensive metabolic model for plastids, mitochondria, and peroxisomes.
