Article Synopsis
- Noncoding and coding RNAs play crucial roles in the growth, development, and stress responses of plants, particularly during the transition from vegetative to reproductive stages in Coffea arabica.
- Researchers sequenced small RNA libraries and combined this data with messenger RNA sequencing to identify different transcript types at key developmental stages.
- The analysis revealed that various small RNAs accumulate in a stage-specific manner, with particular emphasis on miRNAs and their association with hormonal responses and transcription factor expression during floral development.
LysM receptors in Coffea arabica: Identification, characterization, and gene expression in response to Hemileia vastatrix.
PLoS One
February 2022
Pathogen-associated molecular patterns (PAMPs) are recognized by pattern recognition receptors (PRRs) localized on the host plasma membrane. These receptors activate a broad-spectrum and durable defense, which are desired characteristics for disease resistance in plant breeding programs. In this study, candidate sequences for PRRs with lysin motifs (LysM) were investigated in the Coffea arabica genome.

Background: Fungicides of the succinate dehydrogenase inhibitors (SDHIs) group have been used in soybean to control Asian soybean rust (ASR) caused by Phakopsora pachyrhizi. Fungal populations with less sensitivity to SDHI fungicides have been reported since 2015.
Results: In this study, fungal sensitivity to benzovindiflupyr (BZV) and fluxapyroxad (FXD) was assessed using a total of 770 P.
Coffee leaf rust caused by the fungus Hemileia vastatrix is one of the most important leaf diseases of coffee plantations worldwide. Current knowledge of the H. vastatrix genome is limited and only a small fraction of the total fungal secretome has been identified.

- The study focuses on the interaction mechanisms between the endophytic bacterium Herbaspirillum seropedicae and plant hosts, revealing that its genetic makeup supports versatile colonization and nutrient exchange.
- The genome of H. seropedicae, which has over 4,800 genes, indicates its ability to metabolize various carbon and nitrogen sources, as well as to produce hormones like indole acetic acid that can influence plant growth.
- The presence of multiple protein secretion systems and adhesion-related genes suggests that H. seropedicae is well-equipped to interact with and thrive inside a diverse range of plant species.
