Prsrw: An Expert System for Postulating Andinferring Resistance Genes to Wheat Stripe Rust [PDF]

, 2009
Postulating and inferring resistance genes to wheat stripe rust are a complicated process and need abundant expertise. An expert system for postulating and inferring resistance genes to wheat stripe rust (PRSRW) was developed by China Agricultural University. The process of PRSRW was described on the basis of the user's requirement.

Postulation of seedling stem rust resistance genes of Yunnan wheat cultivars in China [PDF]

Plant Protection Science, 2016
To determine stem rust resistance genes of wheat varieties in Yunnan province, 11 Chinese strains of Puccinia graminis f.sp. tritici with different virulence and 1 artificial mutant strain were used in 110 wheat varieties. The results indicated that among the 45 Sr genes, Sr31, Sr5, SrTmp, Sr30, Sr36, Sr8a, Sr11, Sr24, Sr29, Sr34, Sr9e, Sr26, Sr38 ...

Identification of genes for leaf rust resistance in seedlings of wheat cultivars from the Yellow-Huai Basin in China and slow rusting observations in field trials

Czech Journal of Genetics and Plant Breeding, 2023
Wheat leaf rust is a devastating disease worldwide. Identification of leaf rust resistance genes in seedlings and of genes for slow rusting are important in resistance breeding and for gene deployment to control the disease.

Molecular mapping of leaf rust resistance genes in the wheat line Yu 356-9

Journal of Integrative Agriculture, 2015
The Chinese wheat line Yu 356-9 exhibits a high level of resistance to leaf rust. In order to decipher the genetic base of resistance in Yu 356-9, gene postulation, inheritance analyses, and chromosome linkage mapping were carried out.

Dihydropteroate synthase gene mutations in Pneumocystis and sulfa resistance [PDF]

, 2004
Pneumocystis pneumonia (PCP) remains a major cause of illness and death in HIV-infected persons. Sulfa drugs, trimethoprim-sulfamethoxazole (TMP-SMX) and dapsone are mainstays of PCP treatment and prophylaxis.

Non-Authenticity of Spring Barley Genotypes Revealed in Gene Bank Accessions

Plants, 2022
Plant research and breeding depends on plant genotypes; therefore, genotype authenticity of accessions is the basic requirement for users of gene banks. Surprisingly, this extremely important topic is rarely reported in the scientific community.

Potato R1 resistance gene confers resistance against Phytophthora infestans in transgenic tomato plants [PDF]

, 2010
Tomato is challenged by several pathogens which cause loss of production. One such pathogen is the oomycete Phytophthora infestans which is able to attack all the aerial parts of the plant.

Mapping and candidate-gene screening of the novel Turnip mosaic virus resistance gene retr02 in Chinese cabbage (Brassica rapa L.) [PDF]

, 2013
The extreme resistance to Turnip mosaic virus observed in the Chinese cabbage (Brassica rapa) line, BP8407, is monogenic and recessive. Bulked segregant analysis was carried out to identify simple sequence repeat and Indel markers linked to this ...
