Rust fungi are important pathogens of trees, ornamental plants, and food crops. Field research targeting rust diseases across Korea uncovered three distinct species of , affecting different members of the family . In our examination of both wild and cultivated grapevine () species, including , , and , we found as well as a previously undescribed rust species, which we describe here as , which was previously identified as a rust pathogen of spp., has been observed to specifically infect . Through molecular sequence analysis of the ITS, LSU rDNA, and 3 mtDNA regions, we determined the phylogenetic placements of these three species. Our morphological studies revealed the distinguishing features of , particularly its unique teliospore layer and urediniospore dimensions. The emergence of on economically valuable grapevines raises concerns about potential agricultural losses, highlighting the urgency for developing specialized management approaches in viticulture.

Advancements in bioinformatic tools and breakthroughs in high throughput RNA sequencing have unveiled the potential role of non-coding RNAs in influencing the overall expression of disease-responsive genes. Owing to the increasing need to develop resilient crop varieties against environmental constraints, our study explores the functional relationship of various non-coding RNAs in wheat during leaf rust pathogenesis. MicroRNAs (miRNAs) and circular RNAs (circRNAs) were retrieved from SAGE and RNA-Seq libraries, respectively, in the susceptible (HD2329) and resistant (HD2329 + Lr28) wheat Near-Isogenic Lines (NILs).

Global warming and extreme climate conditions caused by unsuitable temperature and humidity lead to coffee leaf rust () diseases in coffee plantations. Coffee leaf rust is a severe problem that reduces productivity. Currently, pesticide spraying is considered the most effective solution for mitigating coffee leaf rust.
