Breeding of Psidium Species for Root Knot Nematode Resistance in Malaysia
The root knot nematode (Meloidogyne incognita) was reported to cause severe damage in guava cultivation in Malaysia. Several long term approaches were taken to find sustainable control for the root knot nematode through breeding. The approaches include protocol development to screen nematode resistance in Psidium species, genetic resource establishment in the field, screening of accessions agai...
متن کاملScreening and identification of cucumber germplasm and rootstock resistance against the root-knot nematode (Meloidogyne incognita).
Root-knot nematodes (Meloidogyne spp) are destructive agricultural pests that reduce the productivity of cultivated vegetables worldwide, especially when vegetables are cropped continuously in greenhouses. Cucumbers (Cucumis sativus L.), in particular, suffer extensive damage due to root-knot nematodes, and only a few wild species are known to be resistant. Grafting of cultivated plants to root...

متن کامل1982 Engineering durable root-knot nematode resistance in crops by RNAi silencing of a root-knot nematode parasitism gene
Secreted proteins coded by parasitism genes expressed in esophageal gland cells mediate infection and parasitism of plants by root-knot nematodes. An essential parasitism gene, designated as 16D10, encodes a conserved root-knot nematode secretory peptide that stimulates root growth and functions as a ligand for a plant transcription factor. Plants were engineered to silence this parasitism gene...
متن کاملIntrogression of Root-Knot Nematode Resistance into Tetraploid Cottons
Root-knot nematode (RKN) resistance introgression into tetraploid cotton (Gossypium spp.) and its ancestral genome origin were examined. Resistance sources (‘Acala NemX’, ‘Clevewilt 6’, Auburn 623 RNR) were compared with diverse germplasm using simple sequence repeat (SSR) markers from chromosomes 7, 11, and 14 and DNA sequence information. Differences (P < 0.05) were observed for mean root gal...
