Project description:This study explored the transcriptomic response of couch grass rhizome meristhematic region exposed to mild, medium and severe drought. The couch grass stress response was compared with the response of two contrasting barley cultivars and the specificities and commonalities in transcriptomic stress response of both species were identified.

Project description:Resistance to herbicides in weeds can be due to alteration(s) in the gene encoding the herbicide target site, or to herbicide degradation via a deviation in plant general metabolism. If target-site-based resistance is easy to study, the multigenic control of metabolism-based resistance renders it much more complex to study. Metabolism-based resistance to herbicides represents the major part of herbicide resistance in black-grass. Its most likely basis is an overexpression of genes encoding enzymes degrading herbicides. We thus seek to identify such overexpressed genes by comparing the transcriptomes of resistant and sensitive black-grass individuals belonging to an F2 line segregating for two resistance genes. Given there are no genomic tools developed for black-grass, this approach will use heterologous hybridisation onto a wheat Affymetrix microarray. Comparison using heterologous hybridisation onto a wheat whole-genome microarray of transcriptome of three pools of black-grass plants obtained 2h30 after herbicide spraying at field rate. The three pools correspond to: · Sensitive plants (killed by herbicide). · Moderately resistant plants (growth impaired by herbicide but plants still alive) · Resistant plants (growth unimpaired by herbicide)

Project description:Grass carp (Ctenopharyngodon idellus), the world’s largest aquaculture fish species, exhibits superior growth in females compared to males. However, the lengthy sexual maturation period of four to five years poses a significant obstacle to the genetic reproduction and breeding of grass carp. Consequently, classical methods such as gonadogenesis or sex reversal through steroid treatment, employed for breeding all-female grass carp, demand considerable time and effort. In this study, we developed an super-fast breeding strategy for generating all-female grass carp in a total of half a year, using a surrogate production method. We first characterized grass carp female germline stem cells (GSCs) from genetic female juveniles at three months post-fertilization (mpf). The female GSCs with XX chromosomes were then transplanted into germ cell-depleted zebrafish larvae at five days post-fertilization (dpf). The transplanted grass carp XX germ cells underwent rapid spermatogenesis in the zebrafish recipient. At three months after transplantation, all zebrafish recipients had developed into males capable of producing the all-X sperm of the grass carp. By using these sperm to fertilize wildtype grass carp eggs, we successfully produced an all-female grass carp offspring. This groundbreaking achievement highlights the potential of surrogate production in the genetic breeding of valuable fish species, and opens a new avenue for advancing genetic breeding in aquaculture.

Project description:Purpose:Salinity is an important environmental factor that affects the physiological activities of fish. The goals of this study are investigating the effect of different saline-alkali stress on grass carp (Ctenopharyngodon idella). Methods: Grass carp individuals, averaging 12 cm in body length, were obtained from Duofu fish farm (Wuhan, China) and cultured at recirculating aquaculture system for 2 weeks before the experiment began. For the challenge, all grass carp were randomly divided into three groups, and then cultured at saline-alkali water with the concentration of 0, 3‰ and 6‰. After 30 days, some grass crap cultured at 3‰ and 6‰ saline-alkali water were injured. At the same time, gill samples of grass carp were collected from 0, 3‰ (grass carp was not injured), 3‰ (grass carp was injured), 6‰ (grass carp was not injured) and 6‰ (grass carp was injured)saline-alkali groups. Total RNA of all samples was isolated using TRIzol® Reagent (Invitrogen) according to the manufacturer's introduction. RNA integrity was assessed using an Agilent 2100 bioanalyzer (Agilent, USA). Samples with RNA integrity numbers (RINs) ≥ 7.5 were subjected to cDNA library construction using TruseqTM RNA sample prep Kit (Illumina). Results:A total of 15 were processed for transcriptome sequencing, generating 94.99Gb Clean Data. At least 5.76Gb clean data were generated for each sample with minimum 91.87% of clean data achieved quality score of Q30. Clean reads of each sample were mapped to specified reference genome. Mapping ratio ranged from 88.59% to 92.84%. The expression of genes was quantified and differentially expressed genes were identified based on their expression.Criteria for differentially expressed genes was set as Fold Change(FC)≥1.5 and Pvalue<0.05. Fold change(FC) refers to the ratio of gene expression in two samples. These DEGs were further processed for functional annotation and enrichment analysis. Conclusions: Our study represents Effects and molecular regulation mechanisms of saline-alkali stress on the healthy grass carp by using RNA-seqtechnology. Our results show that saline-alkali stress will impair the immune system of grass carp.

Project description:SERPINA1, a member of the serine protease inhibitor family, plays a role in viral infection and inflammation by regulating the activities of serine and cysteine proteases. To further investigate the antiviral role SERPINA1 played in GCRV (Grass carp Reovirus) infection, a polyclonal antibody of SERPINA1 was prepared, and the protein interacting with SERPINA1 was screened by CoIP/MS in grass carp hepatopancreas tissue. Samples of hepatopancreas tissues from grass carp (n=3) before (healthy) and 8 days after the infection (post-infection) were selected. Grass carp were infected by intraperitoneal injection. The total tissue proteins were extracted according to the manufacturer’s instructions for cell lysate (Beyotime, Shanghai, China). The types and abundance of proteins bound to SERPINA1 before and after the infection were detected and analyzed using CoIP-MS.

By integrating multi-omic data, we reveal novel links between microbial activity, epithelial cell function, and grassland foraging, providing critical insights into mechanisms underlying grass prevalence and their implications for optimizing ruminant health and productivity. This research enhances our understanding of the grass-microbiome- rumen axis and its role in sustainable grazing systems.
