Characteristics and host range of tomato powdery mildew

powdery mildew of tomato in qazvin province of iran: host range, morphological and molecular characterization

powdery mildew is one of the most important disease concerns of tomato production in different regions of the world, which is caused by different species of erysiphales. the most important causal agents of which are leveillula taurica and oidium neolycopersici. in the present study tomato farms in qazvin province were surveyed and tomato leaves with powdery mildew symptoms were collected. after...

Powdery Mildew Resistance in Tomato by Impairment of SlPMR4 and SlDMR1

Genetic dissection of disease susceptibility in Arabidopsis to powdery and downy mildew has identified multiple susceptibility (S) genes whose impairment results in disease resistance. Although several of these S-genes have been cloned and characterized in more detail it is unknown to which degree their function in disease susceptibility is conserved among different plant species. Moreover, it ...

Functional Characterization of a Syntaxin Involved in Tomato (Solanum lycopersicum) Resistance against Powdery Mildew

Specific syntaxins, such as Arabidopsis AtPEN1 and its barley ortholog ROR2, play a major role in plant defense against powdery mildews. Indeed, the impairment of these genes results in increased fungal penetration in both host and non-host interactions. In this study, a genome-wide survey allowed the identification of 21 tomato syntaxins. Two of them, named SlPEN1a and SlPEN1b, are closely rel...
