Mikania micrantha Kunth is native to tropical America and has invaded subtropical Asia numerous Pacific Islands. It forms dense thickets reduces species diversity populations in its introduced range. This invasive vine also seriously impacts many agricultural crops listed as one of the world’s 100 worst alien species. Its life history characteristics, such production large numbers wind-dispersed seeds, vegetative reproduction, rapid growth, genetic all contribute invasiveness. In this review, we focus on how mechanisms defend against natural enemies boost invasiveness M. micrantha. possesses potent defenses pathogenic fungi, herbivorous insects, parasitic nematodes, exhibits allelopathic potential plant competitors. These defensive abilities, concert with formidable micrantha, potentially leading further naturalization. Several other reviews have summarized biology management species, but ours first review likely enhance Relatively little known about array capabilities micrantha; therefore, there considerable scope for research chemical defenses.

Biocontrol of plant parasitic nematodes by bacteria and fungi: a multi-omics approach for the exploration of novel nematicides in sustainable agriculture

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Июль 26, 2024

Plant parasitic nematodes (PPNs) pose a significant threat to global crop productivity, causing an estimated annual loss of US $157 billion in the agriculture industry. While synthetic chemical nematicides can effectively control PPNs, their overuse has detrimental effects on human health and environment. Biocontrol agents (BCAs), such as bacteria fungi rhizosphere, are safe promising alternatives for PPNs control. These BCAs interact with plant roots produce extracellular enzymes, secondary metabolites, toxins, volatile organic compounds (VOCs) suppress nematodes. root exudates also play crucial role attracting beneficial microbes toward infested roots. The complex interaction between plants rhizosphere against is mostly untapped which opens new avenues discovering novel through multi-omics techniques. Advanced omics approaches, including metagenomics, transcriptomics, proteomics, metabolomics, have led discovery nematicidal compounds. This review summarizes status bacterial fungal biocontrol strategies mechanisms importance omics-based approaches exploration future directions addressed. highlighted potential significance techniques ensure sustainable agriculture.

The annual global production of citrus fruits is over 150 million tons, and 40–50% the are processed into juices other products. processing generates a large amount waste causes environmental issues. In order to reduce impacts, several approaches for management were proposed. fruit contains functional compounds, but extraction these compounds requires adequate facilities. not suitable carry long distances due high percent water content its heavy weight, it store time occurrence fermentation. Some target use in proximity factories. application crop agricultural fields close faculties one possible options. evidence as herbicidal, nematocidal, insecticidal, anti-fungal materials has been accumulated literature three decades. Several involved functions have also identified fruits. However, there no review article focusing on pesticidal activity against weeds, herbivore insects, parasitic nematodes, pathogenic fungi.

Root-knot nematode assessment: species identification, distribution, and new host records in Portugal

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Авг. 8, 2023

Considered one of the most devastating plant parasitic nematodes worldwide, Meloidogyne spp. (commonly known as root-knot (RKNs)) are obligate sedentary endoparasites that establish in roots, causing hyperplasia and hypertrophy surrounding cells, triggering formation galls. These galls will affect root development physiology, leading to substantial yield losses. During 2017-2022, an extensive survey species was undertaken Portugal (mainland islands). A total 1,071 samples were collected by National Plant Protection Organization (DGAV) private farmers from different regions country analysed at Laboratory Nematology (NemaINIAV). Samples which presence sp. detected used perform bioassays obtain females juveniles for further studies. Since accurate identification RKNs is important aspect crop management, morphological biochemical characterisation performed. The common features observed, showing consistency with previous descriptions genus. using esterase (EST) phenotype revealed phenotypes arenaria, M enterolobi, M. hispanica, hapla, incognita, javanica, luci. incognita javanica found be prevalent followed arenaria hapla. This first distribution report performed on RKNs, contributing management strategies updated information status these pests Europe.
