The evolutionary trajectories of specialized metabolites towards antiviral defense system in plants

Molecular Horticulture, Journal Year: 2024, Volume and Issue: 4(1)

Published: Jan. 12, 2024

Abstract Viral infections in plants pose major challenges to agriculture and global food security the twenty-first century. Plants have evolved a diverse range of specialized metabolites (PSMs) for defenses against pathogens. Although, PSMs-mediated plant-microorganism interactions been widely discovered, these are mainly confined plant-bacteria or plant-fungal interactions. PSM-mediated plant-virus interaction, however, is more complicated often due additional involvement virus spreading vectors. Here, we review classes PSMs their emerging roles involved antiviral resistances. In addition, evolutionary scenarios between plant, virus-transmitting vectors presented. These advancements comprehending biochemical language during not only lay foundation understanding potential co-evolution across life kingdoms, but also open gateway fundamental principles biological control strategies beyond. Graphical The putative co-evolutionary triad plant (PSM) mediated viruses insect This dynamic trio depicted through interplay represented by pink green arrows, signifying PSM bidirectional occurring virus, host vector.

A Horizontally Transferred Plant Fatty Acid Desaturase Gene Steers Whitefly Reproduction

Advanced Science, Journal Year: 2023, Volume and Issue: 11(10)

Published: Dec. 25, 2023

Abstract Polyunsaturated fatty acids (PUFAs) are essential nutrients for all living organisms. PUFA synthesis is mediated by Δ12 desaturases in plants and microorganisms, whereas animals usually obtain PUFAs through their diet. The whitefly Bemisia tabaci an extremely polyphagous agricultural pest that feeds on phloem sap of many do not always provide them with sufficient PUFAs. Here, a plant‐derived desaturase gene family BtFAD2 characterized B. it shows the BtFAD2‐9 enables to synthesize PUFAs, thereby significantly enhancing its fecundity. role reproduction further confirmed transferring Drosophila melanogaster , which also increases fruit fly's reproduction. These findings reveal extraordinary evolutionary scenario whereby phytophagous insect acquired plant genes nutrients, lessening nutritional dependency allowing feed reproduce host plants.

Canonical terpene synthases in arthropods: Intraphylum gene transfer

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(51)

Published: Dec. 13, 2024

Insects employ terpenoids for communication both within and between species. While terpene synthases derived from isoprenyl diphosphate synthase have been shown to catalyze terpenoid biosynthesis in some insects, canonical (TPS) commonly found plants, fungi, bacteria were previously unidentified insects. This study reveals the presence of TPS genes likely originating via horizontal gene transfer noninsect arthropods. By examining 361 insect genomes, we identified five species Sciaridae family (fungus gnats). Additionally, Collembola (springtails) Acariformes (mites) among diverse Selected enzymes Sciaridae, Collembola, display monoterpene, sesquiterpene, and/or diterpene activities. Through comprehensive protein database search phylogenetic analysis, be most closely related those Acariformes, suggesting Sciaridae. In model Bradysia coprophila , all are highly expressed adult males, a sex- developmental stage-specific role their products. The finding insects possible evolutionary origin through intraphylum arthropods sheds light on metabolic innovation

Database Bias in the Detection of Interdomain Horizontal Gene Transfer Events in Pezizomycotina

Biology, Journal Year: 2024, Volume and Issue: 13(7), P. 469 - 469

Published: June 26, 2024

Horizontal gene transfer (HGT) is a widely acknowledged phenomenon in prokaryotes for generating genetic diversity. However, the impact of this process eukaryotes, particularly interdomain HGT, topic debate. Although there have been observed biases HGT detection, little exploration has conducted on effects imbalanced databases. In our study, we experiments to assess how different databases affect detection using proteomes from Pezizomycotina fungal subphylum as focus group. Our objective was simulate database imbalance commonly found public biological databases, where bacterial and eukaryotic sequences are unevenly represented, demonstrate that an increase uploaded leads decrease predicted HGTs. For experiments, four with varying proportions but consistent were utilized. We significant reduction detected candidates proportion eukaryotes increased within database. data suggest bias highlights challenges associated confirming presence among fungi potentially other groups Eukarya.

Phenotypic plasticity plays an essential role in the confrontation between plants and herbivorous insects

CABI Agriculture and Bioscience, Journal Year: 2023, Volume and Issue: 4(1)

Published: Dec. 13, 2023

Abstract The interaction between insects and plants is a classic case of coevolution. During the arms race that has continued for 400 million years, mutualistic (such as pollination defense assistance) antagonistic relationships gradually formed complicated under selection pressure from phytophagous insects. Thus, have developed diverse strategies, constantly balancing relationship growth. At same time, evolved ability to adapt resist plant defenses. Throughout this process, phenotypic plasticity continuously helped both groups new environments niches. Epigenetic changes play an important role in formation plastic phenotype. These allow parental traits be passed on offspring, helping offspring insect feeding. genetic variation provide basis phenotypes, can form stable long-term feeding pressure. In review, we summarize strategies counter-defense insects, suggest plays interaction, discuss epigenetics phenotypes.
