Insights From the ‘Black Box’: Survival Strategies of Wheat Rusts and Their Epidemiological Significance

Plant Pathology, Volume 74, Issue 6, Page 1504-1518, August 2025.
Literature demonstrates that wheat rusts can survive through sexual reproduction on alternate hosts, asexual reproduction on wild grasses or volunteers and migration to more favourable areas during critical periods. ABSTRACT Survival between cropping seasons is a challenge for crop pathogens and can dramatically impact epidemic recurrence and ...

Avaliação da atividade fungicida de extratos e óleos essenciais sobre ferrugem asiática da soja

Revista Ciência Agronômica
Os extratos e óleos essenciais extraídos de plantas têm grande potencial no controle de fitopatógenos, por sua ação fungitóxica direta, inibindo o crescimento micelial e a germinação de esporos, e pela capacidade de induzir o acúmulo de fitoalexinas nas ...

Analysis of plant metabolomics data using identification‐free approaches

Applications in Plant Sciences, Volume 13, Issue 4, July-August 2025.
Abstract Plant metabolomes are structurally diverse. One of the most popular techniques for sampling this diversity is liquid chromatography–mass spectrometry (LC‐MS), which typically detects thousands of peaks from single organ extracts, many representing true metabolites.

Occurrence of Telia of Phakopsora pachyrhizi on Kudzu in Texas

Plant Disease, 2008
The first discovery of Asian soybean rust (ASR) caused by Phakopsora pachyrhizi H. Sydow & Sydow in the continental United States was in Louisiana in 2004 (3). In Texas, the uredial stage of this fungus was first found on kudzu (Pueraria lobata) in November 2005 and 3 months later on soybean (Glycine max) (2). The telial stage of P. pachyrhizi was

White Light Orchestrates Mycoparasitic and Infection Activities by Regulating Expression of Effectors in Trichothecium roseum

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
White light‐mediated mycoparasitic and infection activities of Trichothecium roseum. ABSTRACT The fungal developmental processes are orchestrated by white light. Despite the genome assembly of Trichothecium roseum being available, the underlying molecular mechanisms of the white light‐mediated developments of T. roseum remain obscure. It was found that
