Key message The study demonstrates the successful management of Meloidogyne incognita in eggplant using Mi-flp14 RNA interference, showing reduced nematode penetration and reproduction without off-target effects across multiple generations. Abstract Root-knot nematode, Meloidogyne incognita, causes huge yield losses worldwide. Neuromotor function...

Plant-parasitic nematodes pose a major threat to crop production where root-knot nematode Meloidogyne incognita is a serious threat. In spite of several recommendations, we still have few nematicidal options to manage this menace. Here, a series of chalcone derivatives (C1-C14) were synthesized and based on their nematicidal potential, 1-(4-Fluoro-...

Key message This study demonstrates multi-gene silencing approach for simultaneous silencing of several functional genes through a fusion gene strategy for protecting plants against root-knot nematode,Meloidogyne incognita. The ability of root-knot nematode (RKN), Meloidogyne incognita, to cause extensive yield decline in a wide range of cultivated...

Root-knot nematodes (Meloidogyne spp.) are notorious plant-parasitic nematodes that affect agricultural crops. These obligate soil-dwelling parasites typically maneuver the host plant physiology by forming specialized feeding cells resulting in heavy yield losses. Scant management tools are available to effectively combat this pest. In an explorato...

Root-knot nematodes (RKNs) of the genus Meloidogyne are agriculturally important pests, causing serious damage to agricultural crops. Biocontrol strategies have gained unprecedented importance to combat RKNs due to their eco-friendly nature. Here, we have developed a repository of fungi selectively isolated using Caenorhabditis elegans as bait. The...

Insect pests are one of the major biotic stresses limiting yield in commercially important crops. The lepidopteran polyphagous spotted pod borer, Maruca vitrata causes significant economic losses in legumes including pigeonpea. RNA interference (RNAi)-based gene silencing has emerged as one of the potential biotechnological tools for crop improveme...

Insect pests are one of the major biotic stresses limiting yield in commercially important food crops. The lepidopteran polyphagous spotted pod borer, Maruca vitrata causes significant economic losses in legumes including pigeonpea. RNAi-based gene silencing has emerged as one of the potential biotechnological tools for crop improvement. We report...

Meloidogyne incognita is an obligate plant-parasitic nematode causing serious damage to agricultural crops. Major constraints in nematode management arose due to the limited availability of non-fumigant nematicides in conjunction with the considerable ill effects of fumigants on human and non-target organisms. Recently, fluensulfone has been report...

The polyphagous spotted pod borer, Maruca vitrata is an important agricultural pest that causes extensive damage on various food crops. Though the pest is managed by synthetic chemicals, exploration of biotechnological approaches for its control is important. RNAi-based gene silencing is one such tool that has been extensively used for functional g...

Plant–parasitic root-knot nematode Meloidogyne incognita uses an array of effector proteins to establish successful plant infections. Mi-msp-1 and Mi-msp-20 are two known effectors secreted from nematode subventral oesophageal glands; Mi-msp-1 being a putative secretory venom allergen AG5-like protein, whereas Mi-msp-20 is a pioneer gene with a coi...

Entomopathogenic nematodes (EPNs) exhibit complex host-seeking behaviour in soil and utilise the insect- and plant-derived odorants to locate and infect their insect hosts. The odorant response defective (odr) genes were identified in Caenorhabditis elegans through a forward genetic screen for worms defective in odour sensing. It is hypothesised th...

Legume pod borer, Maruca vitrata, has lately emerged as one of the major insect pests of pigeonpea causing considerable crop losses. Thus, efficient management of M. vitrata is an important component for sustained pigeonpea productivity for which information on insect diversity could be useful. Present study was undertaken to evaluate the diversity...
