Molecular Phylogenetics and Mitochondrial Evolution [PDF]

open access: yes, 2022
The aim of the present Special Issue is to address the state-of-art of mitochondrial genomics and phylogenomics. Mitochondrial markers are widespread in phylogenetics; however, it is becoming increasingly clear that (i) many discordance issues arise with

Sequential breakdown of the Cf‐9 leaf mould resistance locus in tomato by Fulvia fulva

open access: yesNew Phytologist, Volume 243, Issue 4, Page 1522-1538, August 2024.
Summary Leaf mould, caused by Fulvia fulva, is a devastating disease of tomato plants. In many commercial tomato cultivars, resistance to this disease is governed by the Cf‐9 locus, which encodes five paralogous receptor‐like proteins. Two of these proteins confer resistance: Cf‐9C recognises the previously identified F.

Selection of Diploid and Tetraploid Banana Hybrids Resistant to Pseudocercospora fijiensis

open access: yesAgronomy, 2021
Black Sigatoka, a disease caused by the fungus Pseudocercospora fijiensis, can lead to the complete loss of banana and plantain production in the absence of chemical control.

Genetic diversity of the banana Fusarium wilt pathogen in Cuba and across Latin America and the Caribbean

open access: yesEnvironmental Microbiology, Volume 26, Issue 5, May 2024.
Our comprehensive survey investigated the Fusarium wilt of bananas (FWB) across all production zones in Cuba, resulting in a collection of 170 Fusarium isolates. By employing genotyping‐by‐sequencing and whole‐genome comparisons, we identified F. purpurascens, F. phialophorum, and F. tardichlamydosporum as the causal agents of FWB in Cuba.

Taxonomy and phylogeny of the genus Mycosphaerella and its anamorphs [PDF]

open access: yes, 2009
Historically plant pathogenic species of Mycosphaerella have been regarded as host-specific, though this hypothesys has proven difficult to test largely due to the inavailability of fungal cultures.

Decoding the molecular mechanism underlying salicylic acid (SA)‐mediated plant immunity: an integrated overview from its biosynthesis to the mode of action

open access: yesPhysiologia Plantarum, Volume 176, Issue 3, May/June 2024.
Abstract Salicylic acid (SA) is an important phytohormone, well‐known for its regulatory role in shaping plant immune responses. In recent years, significant progress has been made in unravelling the molecular mechanisms underlying SA biosynthesis, perception, and downstream signalling cascades.

Variable genome evolution in fungi after transposon-mediated amplification of a housekeeping gene

open access: yesMobile DNA, 2019
Background Transposable elements (TEs) can be key drivers of evolution, but the mechanisms and scope of how they impact gene and genome function are largely unknown.

Next‐generation methods for early disease detection in crops

open access: yesPest Management Science, Volume 80, Issue 2, Page 245-261, February 2024.
Innovative alternative diagnostics allow easier and quicker plant disease detection than traditional methods. These latter methodological approaches require specialized personnel and they usually are more expensive than innovative methods based on field detection with portable instruments which are accessible to non‐specialized personnel.
