Published: Dec. 19, 2022

Plant–pathogen interactions induce a signal transmission series that stimulates the plant’s host defense system against pathogens and this, in turn, leads to disease resistance responses. Plant innate immunity mainly includes two lines of system, called pathogen-associated molecular pattern-triggered (PTI) effector-triggered (ETI). There is extensive exchange recognition process triggering plant immune signaling network. messenger molecules, such as calcium ions, reactive oxygen species, nitric oxide, hormone salicylic acid, jasmonic ethylene, play key roles inducing In addition, heterotrimeric G proteins, mitogen-activated protein kinase cascade, non-coding RNAs (ncRNAs) important regulating transduction This paper summarizes status progress pathway research recent years; discusses complexities of, among, pathways; forecasts future prospects provide new ideas for prevention control diseases.

Sclerotinia sclerotiorum (Lib.) de Bary is a broad host-range fungus that infects an inclusive array of plant species and afflicts significant yield losses globally. Despite being notorious pathogen, it has uncomplicated life cycle consisting either basal infection from myceliogenically germinated sclerotia or aerial ascospores carpogenically sclerotia. This unique among necrotrophic pathogens in inevitably colonizes aging tissues to initiate infection, where saprophytic stage follows the pathogenic phase. The release cell wall-degrading enzymes, oxalic acid, effector proteins are considered critical virulence factors necessary for effective pathogenesis S. sclerotiorum. Nevertheless, molecular basis still imprecise remains topic continuing research. Previous comprehensive sequencing genome revealed new insights into its organization provided deeper comprehension sophisticated processes involved growth, development, virulence. review focuses on genetic genomic aspects fungal biology pathogenicity summarize current knowledge utilized by parasitize hosts.

Controlled-release delivery systems have been widely used to improve the efficacy and bioavailability of pesticides minimize environmental risks. Herein, a fungicide carbendazim (CBZ)-loaded, kind nanovalve including trimethylammoniumpillar[5]arene (AP5), methyl orange (MO)-functionalized mesoporous selenium (MSe) nanopesticides (CBZ@AP5/MSe⊃MO) were prepared. The endowed CBZ@AP5/MSe⊃MO with pH-responsive property, so can respond microenvironment pathogen Sclerotinia sclerotiorum (S. sclerotiorum). First, MO was shed due protonation, AP5-functionalized MSe gradually dissolved in an acid environment. Finally, CBZ released rapidly. It is reported that AP5 as host guest functionalized never applied agriculture. In vitro release experiments showed cumulative rate at pH 4.5 1.74 times higher than neutral addition, we found contact angle maize rape leaves effectively decreased, which could retain more after washout. also decrease dry biomass reducing sugar S.sclerotiorum. holds good safety profile for plants, animal cells, environment owing targeted properties.

Summary De novo allopolyploidization in Brassica provides a very successful model for reconstructing polyploid genomes using progenitor species and relatives to broaden crop gene pools understand genome evolution after polyploidy, interspecific hybridization exotic introgression. B. napus (AACC), the major cultivated rapeseed third largest oilseed world, is young with limited genetic base resulting from its short history of domestication, cultivation, intensive selection during breeding target economic traits. However, pool has been significantly enriched recent decades that benefit worldwide effects by introduction abundant subgenomic variation novel genomic via intraspecific, intergeneric crosses. An important question this respect how utilize such breed crops adapted changing global climate. Here, we review diversity, structure, population‐level differentiation relation known introgressions various Brassicaceae, especially those elucidated genome‐sequencing projects. We also summarize progress cloning, trait‐marker associations, editing, molecular marker‐assisted genome‐wide prediction, describe challenges opportunities these techniques as platforms exploit their value pool.

Sclerotinia sclerotiorum causes severe yield and economic losses for many crop vegetable species, especially Brassica napus . To date, no immune B. germplasm has been identified, giving rise to a major challenge in the breeding of resistance.

Abstract Sclerotinia stem rot (SSR), caused by the necrotrophic fungus sclerotiorum , is one of most devastating diseases for several major oil-producing crops. Despite its impact, genetic basis SSR resistance in plants remains poorly understood. Here, through a genome-wide association study, we identify key gene, BnaA07. MKK9 that encodes mitogen-activated protein kinase confers oilseed rape. Our functional analyses reveal BnaA07.MKK9 interacts with BnaC03.MPK3 and BnaC03.MPK6 phosphorylates them at TEY activation motif, triggering signaling cascade initiates biosynthesis ethylene, camalexin, indole glucosinolates, promotes accumulation H 2 O hypersensitive response, ultimately conferring resistance. Furthermore, variations coding sequence alter activity improve ~30% cultivars carrying advantageous haplotype.
