Encapsulation and application of cell ‐free extracts produced by Penicillium chrysogenum R1 in tomato plants for the control of Fusarium oxysporum
This study aimed to encapsulate and characterize the extracts produced byPenicillium chrysogenum R1 and evaluate their antifungal activity in the plant assay. The capsules were prepared with a chitosan (0.5 mg/mL) and sodium alginate solution (2% w/v), and 20% (v/v) cell-free extract recovered from theP. chrysogenum R1 fermentation. The capsules were synthesized in a 2.5% CaCl2 solution at room temperature. The capsules were characterized by DLS and SEM. To determine the efficiency of the free and encapsulated extract, they were applied to tomato plants infected withFusarium oxysporum. Once the symptoms were observed, th...

The impact of microplastics on yield and economic losses in selected agricultural food commodities
This study aims to estimate the production losses suffered by key crops —rice, wheat, maize, tomato, and peas—due to MPs, along with the resulting economic consequences arising from the direct damage inflicted by MPs. To assess production losses caused by MPs, secondary data from diverse sources were employed for five plant varieties. The economic losses resulting f rom MPs were calculated for the period spanning 2017–2023, with cumulative data aggregated from all states. The study's findings indicate that the presence of MPs corresponds to an annual global output decline ranging from 0.4% to 34.7%. This decline tran...

Analysis of five near-complete genome assemblies of the tomato pathogen Cladosporium fulvum uncovers additional accessory chromosomes and structural variations induced by transposable elements effecting the loss of avirulence genes
Fungal plant pathogens have dynamic genomes that allow them to rapidly adapt to adverse conditions and overcome host resistance. One way by which this dynamic genome plasticity is expressed is through effector... (Source: BMC Biology)

Dietary experience alters predatory behavior of two ladybird species on tomato potato psyllid
In this study, one nonnative resident ladybird,Hippodamia variegata, and one native ladybird,Coccinella transversalis, were investigated. Dietary experience withB. cockerelli as a prey species significantly increased preference for the psyllid in a short term (6 h) Petri dish study where a choice of prey was given. Greater suppression ofB. cockerelli populations by experienced ladybirds was also observed on glasshouse grown tomato plants. This was presumably due to altered prey recognition by experience. The result of this study suggest the potential to improve the impact of biological control agents on invasive pests by p...

Identification of RNA silencing suppressor encoded by citrus chlorotic dwarf-associated virus
ConclusionOverall, the results of this study demonstrate that CCDaV-V2 acts as an activity of silencing suppression. This is the first reported RNA-silencing suppressor encoded by Citlodavirus and will be valuable in revealing the molecular mechanism of CCDaV infection. (Source: Frontiers in Microbiology)

Fine-mapping of a major locus for Fusarium wilt resistance in flax (Linum usitatissimum L.)
Theor Appl Genet. 2024 Jan 21;137(1):27. doi: 10.1007/s00122-023-04528-2.ABSTRACTFine-mapping of a locus on chromosome 1 of flax identified an S-lectin receptor-like kinase (SRLK) as the most likely candidate for a major Fusarium wilt resistance gene. Fusarium wilt, caused by the soil-borne fungal pathogen Fusarium oxysporum f. sp. lini, is a devastating disease in flax. Genetic resistance can counteract this disease and limit its spread. To map major genes for Fusarium wilt resistance, a recombinant inbred line population of more than 700 individuals derived from a cross between resistant cultivar 'Bison' and susceptible ...

Genes, Vol. 15, Pages 115: Conserved Role of Heterotrimeric G Proteins in Plant Defense and Cell Death Progression
tella
Programmed cell death (PCD) is a critical process in plant immunity, enabling the targeted elimination of infected cells to prevent the spread of pathogens. The tight regulation of PCD within plant cells is well-documented; however, specific mechanisms remain elusive or controversial. Heterotrimeric G proteins are multifunctional signaling elements consisting of three distinct subunits, Gα, Gβ, and Gγ. In Arabidopsis, the Gβγ dimer serves as a positive regulator of plant defense. Conversely, in species such as rice, maize, cotton, and tomato, mut...

Structural-Functional Correlations between Unique N-terminal Region and C-terminal Conserved Motif in Short-chain cis-Prenyltransferase from Tomato
Chembiochem. 2024 Jan 15:e202300796. doi: 10.1002/cbic.202300796. Online ahead of print.ABSTRACTNeryl diphosphate (C10 ) synthase (NDPS1), a homodimeric soluble cis-prenyltransferase from tomato, contains four disulfide bonds, including two inter-subunit S-S bonds in the N-terminal region. Mutagenesis studies demonstrated that the S-S bond formation affects not only the stability of the dimer but also the catalytic efficiency of NDPS1. Structural polymorphs in the crystal structures of NDPS1 complexed with its substrate and substrate analog were identified by employing massive data collections and hierarchical clustering a...
