Published: Feb. 6, 2023

Introduction The south American tomato pinworm (Tuta absoluta), an invasive insect pest species, has established itself in more than 33 Chinese prefectures, where it is mainly damaging crops. Immediate efforts have been initiated to find strategies control this pest. Studies shown that biochar (BC) amendment soil can enhance plant growth and resistance herbivory. Methods First, we quantified the morphological performance of plants grown different coconut bran bamboo charcoal (v/v) combinations selected most beneficial one. Then checked T. absoluta survival on combination. Finally, studied leaf metabolite accumulation gene expression changes after growing Results We found 30:1 ratio as its increased height, stem thickness, chlorophyll content, whereas, decreased. metabolome profiles BC leaves showed flavonoids, terpenoids, phenolic acids compared CK. Transcriptome sequencing resulted identification 244 differentially expressed genes. Most upregulated genes were associated with stress-related hub proteins, flavonoid biosynthesis, MAPK phytohormone signaling, terpenoid biosynthesis. Additionally, many related signaling defense was changed response amendment. Discussion conclude induces biosynthesis acids, which improve tolerance against , thus reducing destructive pests.

Plant-microbe interactions play a crucial role in shaping plant growth and development, as well mediating responses to biotic abiotic stresses. In this study, we used RNA-seq data examine the expression profiles of SlWRKY, SlGRAS, SlERF genes during symbiotic association Curvularia lunata SL1 with tomato (Solanum lycopersicum) plants. We also conducted functional annotation analysis by comparative genomics studies their paralogs orthologs genes, other approaches, such gene protein interaction networks, identify characterize regulatory roles these TFs development association. found that more than half investigated SlWRKY exhibited significant upregulation association, including SlWRKY38, SlWRKY46, SlWRKY19, SlWRKY51. Several SlGRAS were upregulated, SlGLD2, SlGLD1, SlERF.C.5, ERF16, SlERF.B12. Conversely, smaller proportion significantly downregulated Furthermore, possible hormonal regulation plant-microbe interactions. identified several upregulated candidate transcripts likely be involved hormone signaling pathways. Our findings are consistent previous on providing further evidence involvement To validate accuracy, performed RT-qPCR analyses selected which showed similar patterns those observed data. These results confirmed accuracy our provided additional support for differential Taken together, study provides new insights into C. lunata, potential could useful guiding future research ways plants microbes interact, may ultimately lead creation better approaches promoting under stressful conditions.

Highjacked by a pseudoenzyme: How eudicot plants make indole

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 26, 2024

Abstract Indole is crucial for plant defense, where it released as a signaling volatile upon herbivore attack and also serves starting precursor defensive specialized metabolites. known to be synthesized in plants from indole-3-glycerol phosphate by the enzyme lyase. Here we report that core eudicots, indole production defense occurs via an alternative pathway. The α subunit of tryptophan synthase (TSA), metabolism, normally binds β (TSB) produce tryptophan. However, show non-catalytic TSB paralogue (TSB-like) can highjack TSA indole. widespread occurrence TSB-like genes eudicots suggests this mechanism formation throughout kingdom.

Dissimilar patterns of variants affecting genes involved in response to herbivory, including those leading difference VOC production, were identified tomato lines with contrasting Tuta absoluta. absoluta is one the most destructive insect pest causing important yield losses both open field and greenhouse. The selection tolerant varieties T. sustainable approaches control this invasive leafminer. In study, genomic diversity two varieties, other susceptible infestation was explored, allowing us identify chromosome regions highly dissimilar pattern. Genes affected by potential functional several processes, herbivory secondary metabolism. A metabolic analysis for volatile organic compounds (VOCs) also performed, highlighting a classes chemicals genotypes. Taken together, these findings can aid breeding programs aiming develop plants

For integrated pest management (IPM) and organic farming, breeding resistant varieties is one of the most eco-friendly approaches, that goes along botanicals other different cultural practices, as use companion plants. Among many species invaded whole world in last decades, frightening tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), a devastating cultivated worldwide. Tomato important agricultural commodities, including main mean subsistence countries from Africa middle East. As chemical pesticides failed to control de spread led reports populations, alternative methods for leafminer must be quickly developed. Many such alternatives count on wide range compounds. The compounds often responsible “constitutive resistance”, synthetized by are methyl-ketones (2-tridecanone), sesquiterpenes (zingiberene), acyl sugars (acylglucose acylsucrose) while produced plants, used isolated substances or mixtures, which have antifeedant, growth inhibiting, repellent, insecticide effects, azadirachtin, carvacrol, cinnamaldehyde, citronellal, eugenol, linalool, nicotine, pyrethrin, rotenone, thujone, thymol, α-terpineol, 1.8-cineol, etc. them already commercially available but their efficacy differ widely. Therefore, deeper understanding resistance mechanism solanaceous related IPM plans developed against T. required programs.

Host Plant Resistance to Insects in Vegetable Crops

Published: Jan. 1, 2024

Host plant resistance is an effective approach to manage insect pests in vegetable crops. This involves the use of traits that deter or reduce feeding and reproduction involving mechanisms antibiosis, antixenosis, tolerance. These affect plant–insect interactions through production metabolites volatiles, which can modify behavior physiology. Tri-trophic between plants, insects, natural enemies also protect plants from herbivory increase parasitization. The transgenics genome editing provides new opportunities enhance host by introducing modifying genes involved insect-resistant traits. Understanding their with crucial for development pest management strategies are environmentally friendly economically sustainable. Overall, offers a promising reducing reliance on synthetic pesticides crop production, but continued studies required fully realize its potential.

Exploring alternative control methods, such as host plant resistance can contribute diminish reliance on insecticides and promote sustainable integrated pest management (IPM) practices. Thus, the identification of new P. ‐resistant cultivars potential wild sources for breeding programmes remains imperative. We evaluated effect 19 genotypes, comprising 16 domesticated varieties three species, oviposition output female well larval performance under no‐choice conditions using detached leaves. also characterized quantified glandular nonglandular trichomes, exploring their correlation with response plants. RESULTS Generally, fewer eggs were oviposited plants, whereas tomatoes Solanum arcanum S. neorickii Corona F1 impaired development. The larvae consumed limited area leaflets from compared other leading lowest weights in both male pupae. All plants exhibited prevalence over except which higher abundance trichomes. Although trichome density correlated longer settlement leaflets, it did not influence oviposition.
