Kaolinite nanoclay-shielded dsRNA drenching for management of Globodera pallida: An environmentally friendly pest management approach.

Globodera pallida, an obligate sedentary endoparasite, is a major economic pest that causes substantial potato yield losses. This research aimed to study the effects of gene silencing of three FMRFamide-like peptides (FLPs) genes to reduce G. pallida infestation on potato plants by using kaolinite nanoclay as a carrier to deliver dsRNAs via drenching.

Identification of genes governing resistance to PCN (Globodera rostochiensis) through transcriptome analysis in Solanum tuberosum.

Potato cyst nematodes (PCNs) are major pests worldwide that affect potato production. The molecular changes happening in the roots upon PCN infection are still unknown. Identification of transcripts and genes governing PCN resistance will help in the development of resistant varieties.

Chaetomium globosum KPC3: An Antagonistic Fungus Against the Potato Cyst Nematode, Globodera rostochiensis.

The potato cyst nematode (Globodera rostochiensis) is one of the most economically important pests of potato (Solanum tuberosum L.), causing significant economic losses worldwide. The identification of biocontrol agents for the sustainable management of G.

An overview of fungal chitinases and their potential applications.

Chitin, the world's second most abundant biopolymer after cellulose, is composed of β-1,4-N-acetylglucosamine (GlcNAc) residues. It is the key structural component of many organisms, including crustaceans, mollusks, marine invertebrates, algae, fungi, insects, and nematodes. There has been a significant increase in the generation of chitinous waste from seafood businesses, resulting in a big amount of scrap.

Resistance Evaluation for Native Potato Accessions against Late Blight Disease and Potato Cyst Nematodes by Molecular Markers and Phenotypic Screening in India.

The potato originated in southern Peru and north-western Bolivia (South America). However, native accessions have also been cultivated in India for many years. Late blight, caused by the fungus , is the most devastating potato disease, while potato cyst nematode ( spp.

Management of potato cyst nematodes with special focus on biological control and trap cropping strategies.

Potato cyst nematodes (PCNs; Globodera spp.) are one of the most difficult pests of potato to manage worldwide. Indiscriminate use of pesticides and their hazardous effects discourage the use of many chemicals for the management of PCNs.

Spraying of dsRNA molecules derived from Phytophthora infestans, along with nanoclay carriers as a proof of concept for developing novel protection strategy for potato late blight.

Background: Phytophthora infestans is a late blight-causing oomycetes pathogen. It rapidly evolves and adapts to the host background and new fungicide molecules within a few years of their release, most likely because of the predominance of transposable elements in its genome. Frequent applications of fungicides cause environmental concerns.

In Vitro Method for Synthesis of Large-Scale dsRNA Molecule as a Novel Plant Protection Strategy.

Double-stranded RNA (dsRNAs) molecules are the precursors and effective triggers of RNAi in most organisms. RNAi can be induced by the direct introduction of dsRNAs in plants, fungi, insects, and nematodes. Until now RNAi is usually established by transformation of the plant with a construct that produces hairpin RNAs.

A new record of Asia II 5 genetic group of (Gennadius) in the major potato growing areas of India and its relationship with tomato leaf curl New Delhi virus infecting potato.

The whitefly, (Gennadius), is responsible for significant yield losses in many crops, including potato, by sucking the phloem sap and transmitting a number of plant viruses. is a complex of cryptic species which is commonly designated as genetic groups. The genetic groups differ biologically with respect to host plant preference, insecticidal resistance, reproduction capacity, and ability to transmit begomoviruses.

Techniques for characterization and eradication of potato cyst nematode: a review.

Correct identification of species and pathotypes is must for eradication of potato cyst nematodes (PCN). The identification of PCN species after completing the life cycle is very difficult because it is based on morphological and morphometrical characteristics. Genetically different populations of PCN are morphologically same and differentiated based on the host differential study.

Comparative pathogenicity of reniform nematode on root-knot resistant and susceptible bidi tobacco.

Comparative pathogenicity of reniform nematode on root-knot resistant ABT 10 and susceptible bidi tobacco A119 revealed that ABT 10 was found significantly superior to A119 with respect to plant growth characters and as good as A119 with respect to multiplication of reniform nematode. Initial inoculum of 1,000 J4 of the nematode found damaging to both ABT 10 and A119 varieties of bidi tobacco.

Estimation of loss and analysis of nicotine, reducing sugar and chloride in bidi tobacco due to reniform nematode under pot conditions.

Estimation of avoidable loss in yield of bidi tobacco due to reniform nematode under pot conditions revealed that variety A 119 suffered heavily than ABT 10 due to reniform nematode. Inoculation of reniform nematode @ 2000 J4 per plant significantly reduced the plant growth characters and increased nematode multiplication preferring A 119 variety. Estimation of avoidable loss in cured shoot yield of bidi tobacco due to infection of reniform nematode in individual variety ABT 10 and A 119 has been estimated to the tune of 30.
