Genome-Wide Identification of Brassica napus PEN1-LIKE Genes and Their Expression Profiling in Insect-Susceptible and Resistant Cultivars

open access: yesCurrent Issues in Molecular Biology, 2022
Recently, it has been reported that a gene (PEN1) in Arabidopsis thaliana is highly resistant to Plutella xylostella. We screened all the homologous genes of PEN1 in Arabidopsis thaliana and found that the motif of these genes was very conserved.

Multiple cytochrome P450 genes: conferring high levels of permethrin resistance in mosquitoes, Culex quinquefasciatus

open access: yesScientific Reports, 2021
Insecticides, especially pyrethroids, are the most important in the insect pest control and preventing insect vector-borne human diseases. However, insect pests, including mosquitoes, have developed resistance in the insecticides that used against them ...

Common resistance mechanisms are deployed by plants against sap-feeding herbivorous insects: insights from a meta-analysis and systematic review

open access: yesScientific Reports, 2022
Despite their abundance and economic importance, the mechanism of plant resistance to sap-feeding insects remains poorly understood. Here we deploy meta-analysis and data synthesis methods to evaluate the results from electrophysiological studies ...

Characterizing the Mechanism of Serotonin Alleviates Rice Resistance to Brown Planthopper Nilaparvata lugens (Homoptera: Delphacidae) Nymphs

open access: yesAgronomy, 2022
Serotonin is a well-known secondary metabolite that plays an important role in many growth and developmental processes, as well as biotic and abiotic stress responses of plants.

miRNA–mRNA Conflux Regulating Immunity and Oxidative Stress Pathways in the Midgut of Blood-Fed Anopheles stephensi

open access: yesNon-Coding RNA, 2015
Blood feeding in Anopheles stephensi initiates a cascade of events that modulate several physiological functions in the mosquito. The midgut epithelium activates several of its molecules, most important among these being microRNAs, which regulate some of

CopE and TLR6 RNAi-mediated tomato resistance to western flower thrips

open access: yesJournal of Integrative Agriculture, 2023
The western flower thrips (WFT; Frankliniella occidentalis) is a mesophyll cell feeder that damages many crops. Management of WFT is complex due to factors such as high fecundity, short reproduction time, ability to feed on a broad range of host plants ...

Maize Combined Insect Resistance Genomic Regions and Their Co-localization With Cell Wall Constituents Revealed by Tissue-Specific QTL Meta-Analyses

open access: yesFrontiers in Plant Science, 2018
Combinatorial insect attacks on maize leaves, stems, and kernels cause significant yield losses and mycotoxin contaminations. Several small effect quantitative trait loci (QTL) control maize resistance to stem borers and storage pests and are correlated ...

Insect Resistance

open access: yes, 2022
Abstract Studies to-date have shown the availability of enough genetic diversity in the wheat genetic resources (land races, wild relatives, cultivars, etc.) for resistance to the most economically important insect pests such as Hessian fly, Russian wheat aphid, greenbug, and Sun pest. Many R genes – including 37 genes for Hessian fly,

Dynamic expression of miRNAs across immature and adult stages of the malaria mosquito Anopheles stephensi

open access: yesParasites & Vectors, 2015
Background MicroRNAs are small non-coding RNAs that are involved in various biological processes including insect development. Anopheles stephensi serves as primary vector of malaria parasite in Asia and exhibits holometabolous life cycle that involves ...

Developmental Regulation of Mi-Mediated Aphid Resistance Is Independent of Mi-1.2 Transcript Levels

open access: yesMolecular Plant-Microbe Interactions, 2004
Mi-1.2, a member of the intracellular, nucleotide-binding site-leucine-rich repeat family of resistance genes, confers resistance in tomato (Lycopersicon esculentum) against both root-feeding nematodes and leaf-feeding aphids.
