Comparative genomics reveals lineage‐associated structural variation and diversification in a barley fungal pathogen

New Phytologist, EarlyView.
Genome‐wide copy‐number variation landscape highlights structural divergence across Puccinia hordei isolates and potentially links Cyp51 amplification to fungicide insensitivity. Summary Leaf rust, caused by Puccinia hordei, is a major barley disease worldwide.

Sistemática das Plantas Vasculares

, 2021
A domesticação das plantas e a invenção da agricultura não têm mais de 12 500 anos (Brown et al., 2009). O Homem foi caçador-recoletor em mais de 95% da sua história. Para sobreviver, os caçadores-recoletores ancestrais tinham de se lembrar dos tipos, formas, qualidades e comportamentos de milhares de espécies de animais, plantas e fungos.

Genome‐Wide Association Study Elucidates the Genetic Architecture of Manganese Tolerance in Brassica napus

Plant, Cell &Environment, EarlyView.
ABSTRACT Brassica napus (canola) is a significant contributor to the world's oil production and is cultivated across continents, yet acidic soils with aluminium (Al3+) and manganese (Mn2+) toxicities limit its production. The genetic determinants underlying natural variation for acidic soil tolerance in canola are unknown and need to be determined ...

Spatiotemporal Dynamics of Cytosolic NADPH in Living Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT In plants, an adequate supply of Nicotinamide adenine dinucleotide phosphate (NADPH) in the cytosol is crucial for maintaining a variety of biosynthetic and antioxidant reactions. Cytosolic NADPH is mainly generated via four enzymatic pathways: NADP‐dependent malic dehydrogenase (NADP‐ME), cytosolic oxidative pentose phosphate pathway (cOPPP),

Rice Orange Leaf Phytoplasma Imp Protein Blocks G–M Interaction by Binding Glycoprotein G to Suppress Rice Stripe Mosaic Virus Infection

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants frequently encounter multiple pathogens concurrently, yet the molecular bases of pathogen–pathogen interactions during mixed infections remain largely unresolved. Here we show that co‐infection of rice by Rice orange leaf phytoplasma (ROLP) and Rice stripe mosaic virus (RSMV) markedly suppresses RSMV proliferation in both host plants ...

Modulation of Anaphase‐Promoting Complex Genes Regulates Root‐Knot Nematode Gall Development and Plant Susceptibility

Plant, Cell &Environment, EarlyView.
ABSTRACT The anaphase‐promoting complex/cyclosome (APC/C) is a multi‐subunit E3 ubiquitin ligase that regulates cell cycle progression, but its role in plant‐pathogen interactions is poorly understood. Here, we demonstrate that regulation of the ubiquitin–proteasome system, involving APC/C‐associated components, is critical for coordinating host cell ...

Perturbation of Spermine Homoeostasis Uncouples Hypersensitive Cell Death From Systemic Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

VARIACIÓN ESTACIONAL DE LAS ASCOSPORAS DE Helicogermslita (XYLARIACEAE) EN LA ATMÓSFERA DE BAHÍA BLANCA, ARGENTINA.

Polibotánica, 2020
Helicogermslita (Xylariaceae, Ascomycota) se caracteriza por poseer ascosporas cuyo carácter distintivo es su surco germinativo en forma de ranura helicoidal que va de un extremo a otro con dos o más giros visibles en la superficie.
