Bacillus thuringiensis Cry5, Cry21, App6 and Xpp55 proteins to control the plant pest nematodes Meloidogyne javanica and M. incognita

Project description:The global imperative to enhance crop protection while preserving the environment has increased interest in the application of biological pesticides. Bacillus thuringiensis (Bt) is a Gramm-positive bacterium that can produce nematicidal proteins and accumulate them in parasporal crystals. Root-knot nematodes are obligate root plant parasitic which are distributed worldwide, causing severe damages to the infested plants and, consequently, large yield reductions. In this work, we have evaluated the toxicity of the crystal proteins Cry5, Cry21, App6, and Xpp55 against two root-knot nematodes belonging to the Meloidogyne genus (M. incognita and M. javanica). The results show that all four proteins, when solubilized, were highly toxic for both nematode species. To check the potential of using Bt strains producing nematicidal crystal proteins as biopesticides to control plant parasitic nematodes in the field, in planta assays were conducted, using two wild Bt strains which produced Cry5 or a combination of App6 and Cry5 proteins. The tests were carried out with cucumber or with tomato plants infested with M. javanica J2, subjected to irrigation with spore+cristal mixtures of the respective strains. The results showed that the efficacy of the nematicidal activity was plant-dependent, as Bt was able to reduce emerged J2 in tomato plants but not in cucumber plants. In addition, the toxicity observed in the in planta assays was much lower than expected, highlighting the challenge of the crystal proteins to exert their toxicity. This emphasizes the delivery of the Bt proteins as crucial for its use to control root-knot nematodes.

Expression data from brown planthhoper (BPH) infested and non-infested rice

Project description:KMD is genetically engenered to be highly resistant to lepidopteran pests through expressing a synthetic cry1Ab gene and its parent non-transgenic rice is Xiushui 11.The developmental duration of BPH feeding on KMD2 was significantly delayed. And moreover, the fecundity of BPH was significantly lower when fed on Bt rice than on the non-Bt parental plants.To investigate unintended effects in KMD2 that causes changes in BPH performance, we performed microarray (GeneChip) analysis to compare the gene expression profiles between Bt rice and non-transgenic parental plants in response to BPH infestation. We used microarrays to detect Bt-independent variation, which might render Bt rice more defensive or less nutritious to BPH. For BPH treatment, 10 second-instar nymphs were infested onto each 30-day-old seedling. After 72 h, the BPH nymphs were carefully removed and rice shoots of both BPH-infested and non-infested plants were sampled for microarray analysis. There were four treatments: Xiushui 11-non infested, Xiushui 11-BPH infested, KMD2-non infested, KMD2-BPH infested, three biological replications.

Comparative transcriptome profiles of cotton (G. hirsutum L. cv. Bikaneri narma) during boll development stages under bollworm infested biotic stress

Project description:Comparative transcriptome profiles of cotton (G. hirsutum L. cv. Bikaneri narma) during boll development stages (0, 2, 5 and 10 dpa) under bollworm infested biotic stress. Cotton is one of the most commercially important fibre crops in the world and used as a source for natural textile fibre and cottonseed oil. The biotic stress is one of the major constraints for crop production. Cotton bollworm (Helicoverpa armigera) is one the major insect pest in cotton and drastically damages the cotton boll. To decipher the molecular mechanisms involved in cotton boll/fibre cell development, transcriptome analysis has been carried out by comparing G. hirsutum L cv. Bikaneri narma cotton boll samples induced by biotic stress (bollworm infested) and that their respective control cotton bolls collected under field conditions. Cotton bolls were collected at fibre initiation (0, 2 dpa/days post anthesis) and elongation (5, 10 dpa) stages for both control and biotic stress condition and gene expression profiles were analyzed by Affymetrix cotton GeneChip Genome array.

Rice plants infested with planthoppers

Project description:Infestation with white-backed planthopper (WBPH) to rice caused induced resistance to rice pathogens but brown planthopper (BPH) infestation induce weaker resistance to rice pathogens. We compared changes in gene expression in rice plants infested with WBPH and BPH to gain some insight into the WBPH-induced resistance to rice pathogens. An analysis, using microarrays, of gene expression in rice plants infested with these planthoppers revealed that WBPH infestation caused high induction of many defense-related genes including pathogenesis-related (PR) genes than BPH infestation. Furthermore, hydroperoxide lyase 2 (OsHPL2) which is an enzyme to produce C6 volatiles was induced by WBPH infestation, but not by BPH infestation. Keywords: response to herbivory; induced resistance
