cysts/oryza sativa

The host range of the corn cyst nematode, Heterodera zeae, recently detected in Maryland, was investigated. A total of 269 plant entries, representing 68 families, 172 genera, and 204 species, was inoculated with cysts or a mixture of eggs and second-stage juveniles of H. zeae. The host range of the

Inheritance of resistance to cyst nematode (Heterodera sacchari) in Oryza sativa was investigated by inoculation tests with isolate 244 from Congo in segregating populations derived from hybridisation between O. sativa and its African sister cultivated species, O. glaberrima. We found that the

From June 2018 to November 2019, a survey for cyst-forming nematodes was conducted in rice fields in Henan Province of central China. Cysts were recovered from two rice fields (N32° 14' 048″8 and E115° 4' 008″) at Huangchuan County, leading to more intensive sampling. A further 25 soil samples were

Oryza meyeriana (O. meyeriana), with a GG genome type (2n = 24), accumulated plentiful excellent characteristics with respect to resistance to many diseases such as rice shade and blast, even immunity to bacterial blight. It is very important to know if the diseases-resistant genes exist and express

Eyespot is a fungal disease of the stem base of cereal crops and causes lodging and the premature ripening of grain. Wheat cultivar Cappelle Desprez contains a highly durable eyespot resistance gene, Pch2 on the long arm of chromosome 7A. A cDNA-amplified fragment length polymorphism (AFLP) platform

A resistance (R) gene-rich 2S chromosomal segment from Triticum ventricosum contains a cereal cyst nematode (CCN; Heterodera avenae) R gene locus CreX and a closely linked group of genes (Sr38, Yr17, and Lr37) that confer resistance to stem rust (Puccinia graminis f. sp. tritici), stripe rust (P.

Exposure of dehulled, dormant red rice (Oryza sativa) seeds to dormancy-breaking treatments (10 mm sodium nitrite, 20 mm propionic acid, 30 mm methyl propionate, 40 mm propionaldehyde, or 70 mmn-propanol) induced tissue pH acidification during chemical contact at least 12 h before visible

Root-knot nematodes secrete proteinaceous effectors into plant tissues to facilitate infection by suppressing host defences and reprogramming the host metabolism to their benefit. Meloidogyne graminicola is a major pest of rice (Oryza sativa) in Asia and Latin America, causing important crop losses.
