Project description:Temperature is a critical environmental factor governing plant growth and development. The difference between day temperature (DT) and night temperature (NT), abbreviated as DIF, influences plant architecture. Subjecting plants to artificial DIF treatments is an effective strategy in ornamental horticulture. For example, negative DIF (when DT – NT < 0) generally inhibits stem elongation, resulting in dwarf plants. However, the mechanisms underlying stem growth regulation by DIF remains to be completely elucidated. In this study, we aimed to analyze the growth, transcriptome, and phytohormone profiles of tomato (Solanum lycopersicum) seedlings grown under different DIF treatments. Under positive DIF (when DT – NT > 0), in contrast to the control temperature (25°C/20°C, DT/NT), high temperature (30°C/25°C) increased stem length and thickness, as well as the number of xylem vessels. Conversely, compared with the positive high temperature DIF treatment (30°C/25°C), under negative DIF treatment (25°C/30°C) stem elongation was inhibited, but stem thickness and the number of xylem vessels were not affected. The negative DIF treatment decreased the expression of gibberellin (GA)-, auxin-, and cell wall-related genes in the epicotyl, as well as the concentrations of GAs and indole-3-acetic acid (IAA). The expression of these genes and concentrations of these hormones increased under high temperature compared to those under the control temperature positive DIF. Our results suggest that stem length in tomato seedlings is controlled by changes in GA and IAA biosynthesis in response to varying day and night temperatures.

Project description:Purpose: Many studies have demonstrated that ZFPs have important functions in many biological processes, including plant growth and development, stress response, and phytohormone response. RanBP2-type zinc finger transcription factors have been characterized in animals and humans. However, their functions remain largely unknown in plants. Therefore, the functions of RanBP ZFPs in plants need further study to shed new insights into the importance of these transcription factors in developmental processes. Methods: The transcriptomes of between overexpression of SlRBZ transgenic and wild-type tomato by RNA-seq analysis were evaluated using the Illumina HiSeq⢠2000 sequencing platform. Raw sequences were filtered and the resulting sets of clean reads were used for the following analysis by Tophat and DEGseq software. qRTâPCR validation was performed using SYBR Green assays. Results: In this study, we identified a RanBP2-type zinc finger protein gene (SlRBZ) in tomato. SlRBZ was constitutively expressed in roots, stems, leaves, flowers and fruits. Overexpression of SlRBZ resulted in etiolated and dwarf phenotypes in tomato. Determination of physiological index showed that chlorophyll, carotenoid, and GAs contents were evidently decreased in transgenic plants. Furthermore, the qRT-PCR and RNA-Seq analyses demonstrated that the transcription of the genes involved in these biosynthesis pathways obviously decreased in SlRBZ-OE plants. In addition, ultrastructural observation by transmission electron microscopy indicated that plastids could not develop into mature chloroplasts with normal chloroplast membrane and thylakoid membrane system in SlRBZ-OE plants. Conclusions: The results suggest that overexpression of SlRBZ may impair the biosynthesis of chlorophyll, carotenoid, and gibberellin through blocking chloroplast development, resulting in etiolation and dwarfism in tomato. The transcriptomes of between overexpression of SlRBZ transgenic and wild-type tomato by RNA-seq analysis were evaluated, in duplicate, using the Illumina sequencing platform.

Project description:Abstract Objective: This study was designed to reveal the potential molecular mechanisms of long-term overgrazing-induced dwarf of sheepgrass (Leymus chinensis). Methods: The electrospray ionization-mass spectrometry (ESI-MS) system was used to generate the proteomic data in dwarf sheepgrass from long-term overgrazed rangeland and normal sheepgrass from long-term enclosed rangeland. The differentially expressed proteins (DEPs) between dwarf and normal sheepgrass were identified, following the analyses of potential functions and interactions of DEPs. Additionally, the expressions of DEPs were confirmed by high performance liquid chromatography-mass spectrum (HPLC-MS) system with multiple reaction monitoring (MRM) method. Results: A total of 51 up-regulated proteins and 53 down-regulated proteins were identified in the dwarf sheepgrass, compared with the normal controls. Some proteins like SAT5_ARATH and DAPA_MAIZE were enriched in the pathway of amino acid biosynthesis. In the protein-protein interaction network, RPOB2_LEPTE, A0A023H9M8_9STRA, ATPB_DIOEL, RBL_AMOTI and DNAK_GRATL interacted with each other. Furthermore, 4 modules were extracted from the PPI network. In addition, the HPLC-MS analysis confirmed the up-regulation of ATPB_DIOEL and the down-regulation of DNAK_GRATL in dwarf samples compared with the controls. Conclusion: The up-regulated ATPB_DIOEL and down-regulated DNAK_GRATL, as well as the proteins that interacted with them, such as RPOB2_LEPTE, A0A023H9M8_9STRA and RBL_AMOTI, may be associated with the long-term overgrazing-induced sheepgrass dwarf.

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:Kinase activity of cGMP-dependant, type II, protein kinase (PRKG2) is required for the proliferative to hypertrophic growth transition of growth plate chondrocytes during endochondral ossification. Loss of PRKG2 function in rodent and bovine models results in dwarfism. We compared growth plate cartilage gene expression profiles of PRKG2R678X/R678X, dwarf and PRKG2R678X/+, unaffected Angus cattle using microarray technology to discover pathways regulated by PRKG2. Calves used in this analysis were produced by the mating between a dwarf carrier sire and two dams- a mother (carrier) and daughter (dwarf) pair. Each dam produced three calves by embryo transfer, which were born in two calving groups. Growth plate cartilage was harvested from the tibia of each animal at approximately 215 days of age. Total RNA was extracted by a modified Trizol protocol. The bovine cDNA microarray (GEO Accession: GPL8813) was used for this analysis. Samples were labeled with Cy3 or Cy5 and hybridized by dye swapping the dwarf (4 dwarf animals- 2 per dam/calving group) and unaffected individuals (2 unaffected animals- 1 per dam/ calving group) such that each dwarf was compared to the unaffected full-sib produced in the same calving group. Each cDNA array was analyzed at three different PMT levels (PMT70,80 and 90), resulting in 12 total image files for statistical analysis. Dwarf PRKG2 R678X homozygous cattle were compared to unaffected, age matched samples. Samples were labeled with Cy3 or Cy5 and hybridized by dye swapping the dwarf (4 dwarf animals- 2 per dam/calving group) and unaffected individuals (2 unaffected animals- 1 per dam/ calving group) such that each dwarf was compared to the unaffected full-sib produced in the same calving group (i.e. unaffected samples had 2 technical replicates). Each cDNA array was analyzed at three different PMT levels (PMT70,80 and 90), resulting in 12 total image files for statistical analysis.
