متن کاملTransferability of SSR markers from related Uredinales species to the coffee rust Hemileia vastatrix.
The aim of the present research was to test the transferability of simple sequence repeat (SSR) markers developed in two Uredinales species to Hemileia vastatrix, coffee rust. The development of efficient techniques for the identification of H. vastatrix isolates is imperative, given the continuous development of new races. The transferability of 25 SSR markers developed in the related Uredinal...
متن کاملEvidence for hyperparasitism of coffee rust (Hemileia vastatrix) by the entomogenous fungus, Lecanicillium lecanii, through a complex ecological web
The entomogenous fungus, Lecanicillium lecanii is hyperparasitic on Hemileia vastatrix , the cause of coffee leaf rust in the laboratory, and has frequently been observed attacking it in the field. The existence of a complex ecological web involving the spatially clustered mutualism of an ant ( Azteca instabilis ) with a scale insect ( Coccus viridis ), where the scale insect was infected by L....
متن کاملIntraguild predation provides a selection mechanism for bacterial antagonistic compounds.
Bacteriocins are bacterial proteinaceous toxins with bacteriostatic or bacteriocidal activity towards other bacteria. The current theory on their biological role concerns especially colicins, with underlying social interactions described as an example of spite. This leads to a rock-paper-scissors game between colicin producers and sensitive and resistant variants. The generality of this type of...
متن کاملCryptosexuality and the Genetic Diversity Paradox in Coffee Rust, Hemileia vastatrix
BACKGROUND Despite the fact that coffee rust was first investigated scientifically more than a century ago, and that the disease is one of the major constraints to coffee production--constantly changing the socio-economic and historical landscape of the crop--critical aspects of the life cycle of the pathogen, Hemileia vastatrix, remain unclear. The asexual urediniospores are regarded as the on...
