“…The results of our experiment revealed distinct disease symptoms across different treatment groups (Figure 1). Vine plants inoculated with F. equiseti displayed significant disease symptoms, consistent with previous reports on the pathogenicity of this fungus [2]. On the other hand, the absence of disease symptoms in the yeast treatment group is in line with research highlighting the potential of BCAs, such as M. guilliermondii, to confer resistance against pathogens and promote plant health [15,16].…”

“…M. guilliermondii is a beneficial yeast known for its potential in mitigating abiotic stress effects and enhancing crop performance. On the other hand, F. equiseti is a pathogenic fungus that poses a risk to Vitis vinifera [2]. By including both microorganisms in the experimental setup, it was possible to evaluate their contrasting effects on plant health and growth.…”

“…One notable pathogen that has become a concern in grapevine cultivation is Fusarium equiseti. In 2019, the first infection of Vitis vinifera by Fusarium equiseti was reported in Spain, posing a new risk to grape cultivation [2]. This pathogen, detected in nurseries, has raised alarm within the grape industry.…”

This article emphasizes the crucial importance of yeast Meyerozyma guilliermondii (Patent CECT13190) as a biological control agent (BCA) in eliciting defensive responses in vine plants, and is supported by comprehensive physiological, proteomic, and transcriptomic analyses. The results demonstrate that the BCA M. guilliermondii can induce enhanced defensive responses, as reflected in the regulation of key proteins. Notably, the upregulated expression of calmodulin and pathogenesis-related protein 10 (PR-10) are indicative of a complex interplay between calcium signalling, salicylic acid accumulation, and the elicitation of plant defence responses against pathogens. Furthermore, changes in microtubule dynamics and proteins related to protein synthesis and folding are observed, confirming the elicitation of defence responses. The correspondence between proteomic and transcriptomic analyses for genes codifying pathogenesis-related proteins, such as Vcgns1, VviTL1, and Vcchit1b, reinforces the empirical robustness of our findings. Collectively, our research explores the modulation of plant defences by the BCA, opening promising avenues for innovative agricultural strategies that enhance crop resilience and productivity.

“…Due to Fusarium spp. are well known soilborne fungi, we used root dipping and soil inoculation methods to test the pathogenicity of our isolates according to the protocols required for these fungi 12,[26][27][28] . The pathogenicity tests were focused on determining the pathogenic role of F. oxysporum PV-534 from Portugal because it was isolated in a high consistency from almond trees showing severe symptoms of decline and xylem discoloration with 100% of incidence.…”

Severe Fusarium wilt and crown root symptoms were observed in almond orchards in Portugal. The present study elucidates the etiology of the disease through molecular, phenotypic, and pathogenic characterization. Three Fusarium isolates from Portugal were tested and 12 Fusarium isolates from almond from Spain were included for comparative purposes. Their identity was inferred by phylogenetic analysis combining tef1 and rpb2 sequences. The Portuguese isolates were identified as Fusarium oxysporum sensu stricto (s.s.), and the Spanish isolates as Fusarium nirenbergiae, F. oxysporum (s.s.), Fusarium proliferatum, Fusarium redolens (s.s.), Fusarium sambucinum (s.s.), and Fusarium sp. Fungal colonies and conidia were characterized on potato dextrose agar (PDA) and on Synthetischer Nährstoffarmer agar, respectively. The colonies had a variable morphology and their color ranged from white to pale violet. Typical Fusarium micro- and macroconidia were characterized. Temperature effect on mycelial growth was evaluated on PDA from 5 to 35 °C, with optimal growth temperature ranging between 16.8 and 26.4 °C. The pathogenicity of F. oxysporum was demonstrated by inoculating almond plants (‘Lauranne’) grafted on GF-677 or Rootpac 20 rootstocks. A significant reduction in plant growth, wilting, and xylem discoloration was observed, with Rootpac 20 being more susceptible than GF-677. Infections were also reproduced using naturally infested soils. Almond plants (‘Lauranne’) were inoculated with isolates of all Fusarium species, with F. redolens from Spain and F. oxysporum from Portugal being the most aggressive.
