چکیده

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 Uredinales species Puccinia coronata f. sp lolli and Melampsora linii to H. vastatrix was tested. A low level of transferability of SSRs was detected, and only 4 potential markers that can be used to fingerprint the coffee rust races were identified.

Annotation of a hybrid partial genome of the coffee rust (Hemileia vastatrix) contributes to the gene repertoire catalog of the Pucciniales

Coffee leaf rust caused by the fungus Hemileia vastatrix is the most damaging disease to coffee worldwide. The pathogen has recently appeared in multiple outbreaks in coffee producing countries resulting in significant yield losses and increases in costs related to its control. New races/isolates are constantly emerging as evidenced by the presence of the fungus in plants that were previously r...

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...

Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee Arabica. In this work, a 454-pyrosequencing transcriptome analysis of H. vastatrix germinating urediniospores (gU) and appressoria (Ap) was performed and compared to previously published in planta haustoria-rich (H) data. A total of 9234 transcripts were identified and annotated. Ca. 50% of these tr...
