Project description:Phytophthora blight is a highly destructive soil borne disease caused by Phytophthora capsici Leonian, which seriously threatens global pepper production. Grafting is one of the important means to improve plant disease resistance and prevent soil borne diseases in vegetable production. However, the molecular mechanism by which grafting enhances the resistance of pepper to Phytophthora blight is still unclear. This study used Phytophthora capsici resistant strain ‘ZCM334’ and susceptible strain ‘Early Calwonder’ as rootstocks, and ‘Early Calwonder’ as scions for grafting. Phenotypic observation and cytological analysis showed that compared with the ‘Early Calwonder’ self rooted plants, the ‘ZCM334’ grafted plants had a later onset of disease, stronger resistance, and less damage to leaf cells, indicating that grafting can significantly improve the resistance of pepper to Phytophthora capsici. This study identified differentially expressed proteins (DEPs) in the leaves and roots of ‘ZCM334’ grafted plants and ‘Early Calwonder’ self rooted plants through proteomic analysis based on iTRAQ technology, and 478 and 349 DEPs were identified between their leaves and roots, respectively. These DEPs were mainly involved in metabolic process, cellular process, response to stimulus and catalytic activity processes. We identified and screened 12 DEPs with consistent expression trends in the leaves and roots of ‘ZCM334’ grafted plants and ‘Early Calwonder’ self rooted plants, including seven DEPs related to Phytophthora capsici resistance (CA01g31060, CA02g15780, CA02g30850, CA01g11410, CA05g12260, CA03g35150, and CA03g36980) and five proteins with unknown functions (CA01g26190, CA11g10620, CA12g02730, CA01g20890 and CA02g11340). Through qRT-PCR analysis, a significant correlation was observed between the protein and transcript levels of these 12 DEPs, and their expression characteristics were analyzed in the roots and leaves of ‘ZCM334’ grafted plants and ‘Early Calwonder’ self rooted plants at different stages (0h, 12h, 24h, and 36h) after inoculation with Phytophthora capsici. This study provides valuable information for exploring the molecular mechanisms by which grafting enhances the resistance of pepper to Phytophthora blight and the excavation of these key genes provides research ideas for studying the regulatory network of pepper resistance to Phytophthora capsici.

Project description:Chrysanthemum is a garden plant with good economic benefit and high ornamental value. Chrysanthemum in the key period of flowering in autumn and winter, vulnerable to cold damage, affecting the normal growth of the chrysanthemum plant and even death. little is known regarding the study of histone crotonylation in plant cold response. In this study, we first obtained reference chrysanthemum transcriptome data via RNA sequencing. Next, we quantitatively investigated the chrysanthemum proteome, crotonylation, and the association between them in chrysanthemum following low temperature. In total, 365669 unigenes, 6693 proteins and 2017 crotonylation sites were quantified under low temperature stress. There were 24631 up-regulated and 22648 down-regulated unigenes (absolute log2-fold change > 1 and P value<0.05), 393 up-regulated and 500 down-regulated proteins using a 1.2-fold threshold (P<0.05). The lysine crotonylation mainly influenced in photosynthesis, ribosome, antioxidant enzyme and ROS system. In the process of low temperature, 61 lysine crotonylation sites in 89 proteins were up-regulated and 87 lysine crotonylation sites in 72 proteins are down-regulated (1.2-fold threshold, P<0.05).

Project description:In this study, Solexa sequencing technology has been used to discover small RNA populations of self-grafted watermelon and grafted watermelon (bottle gourd and squash were used as rootstocks). A total of 11,458,476, 11,614,094 and 9,339,089 raw reads representing 2,957,751, 2,880,328 and 2,964,990 unique sequences were obtained from the scions of self-grafted watermelon and watermelon grafted on-to bottle gourd and squash at two true-leaf stage, respectively. 39 known miRNAs belonging to 30 miRNA families and 80 novel miRNAs were identified in our small RNA dataset. Compared with self-grafted watermelon, 20 (5 known and 15 novel miRNAs) and 51 (21 known miRNAs and 30 novel miRNAs) miRNAs were expressed significantly different with higher abundance or lower abundance in watermelon grafted on to bottle gourd and squash, respectively. The differentially expressed miRNA target various transcriptional factors and other genes which involved in a wide range of biological processes. This study was firstly conducted to identify and compare miRNAs on genome-wide scale in watermelon grafting system. The miRNAs expressed differentially when watermelon was grafted onto different rootstocks suggesting that miRNAs might play an important role in diverse biological and metabolic processes in watermelon and grafting may possibly by changing miRNAs expression to regulate plant growth and response to stresses. The small RNA transcriptomes obtained in this study provided insights into molecular basis of miRNA regulation of genes expressed in self-grafted and grafted watermelon.

Project description:According to the field observation result, the grafting treatment used in this study was found that 101-14MG rootstocks grafted with Crimson Seedless had a positive influence on fruit coloring. Combined metabolomic and transcriptomic analyses were conducted with different treatment grape of own rooted Crimson Seedless cultivar, and grafted 101-14MG, 110R, SO4 rootstocks with Crimson Seedless cultivar. Peonidin 3-O-glucoside, Delphinidin 3-O-glucoside, Cyanidin 3-O-glucoside, Malvidin 3-O-glucoside, Petunidin 3-O-glucoside were identified as the pigments responsible for the purplish red color peels. The results showed that the grafting material of rootstock 101-14MG could promote the accumulation of anthocyanins in grapefruit in advance. Transcriptome analysis revealed the anthocyanins biosynthetic related genes from the upstream (phenylalanine ammonia-lyase) to the downstream (anthocyanidin 3-O-glucosyltransferase, anthocyanidin synthase) were almost upregulation during anthocyanins increased. However, all these genes were highly expressed in samples G715 (Crimson Seedless/ Crimson Seedless), suggested that self-grafting rootstocks might have an earlier response to fruit color-related metabolism. A transcription factors-scale protein interaction (PPI) analysis showed that MYB4, MYB44, MYB80, and dead-box RNA helicases might be the core regulatory genes. Our results provide global transcriptional changes in grape peel color regulation under different grafting conditions for improving the breeding process.
