Towards breeding of rapeseed (<i>Brassica napus</i>) with alien cytoplasm and powdery mildew resistance from Ethiopian mustard (<i>Brassica carinata</i>)

Tempered mlo broad-spectrum resistance to barley powdery mildew in an Ethiopian landrace

Recessive mutations in the Mlo gene confer broad spectrum resistance in barley (Hordeum vulgare) to powdery mildew (Blumeria graminis f. sp. hordei), a widespread and damaging disease. However, all alleles discovered to date also display deleterious pleiotropic effects, including the naturally occurring mlo-11 mutant which is widely deployed in Europe. Recessive resistance was discovered in Eth...

An Arabidopsis mutant with enhanced resistance to powdery mildew.

We have identified an Arabidopsis mutant that displays enhanced disease resistance to the fungus Erysiphe cichoracearum, causal agent of powdery mildew. The edr1 mutant does not constitutively express the pathogenesis-related genes PR-1, BGL2, or PR-5 and thus differs from previously described disease-resistant mutants of Arabidopsis. E. cichoracearum conidia (asexual spores) germinated normall...

Hydroponically Produced Mini-cucucmber with Improved Powdery Mildew Resistance

Additional Index Words. Cucumis sativus L., greenhouse, protected culture, beit alpha cucumber Abstract. The Beit Alpha (BA) cucumber is a new commodity for the Florida greenhouse industry. In past trials, BA cultivar production and quality were compared to traditional ‘Dutch’ or European cucumber cultivars. The cv. Sarig, a BA-type, produced three times more yield than the Dutch-type cv. Kalun...

Chemical suppressors of mlo-mediated powdery mildew resistance

Loss-of-function of barley mildew locus o (Mlo) confers durable broad-spectrum penetration resistance to the barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh). Given the importance of mlo mutants in agriculture, surprisingly few molecular components have been identified to be required for this type of resistance in barley. With the aim to identify novel cellular factors cont...
