Sugar conundrum in plant-pathogen interactions: roles of invertase and sugar transporters depend on pathosystems

Yong-Hua Liu et al.

Summary: Analyses of plant species and pathogens show that specific roles of invertases and sugar transporters in plant-pathogen interactions depend on the lifestyle and infection strategies of pathogens. Cell wall invertase (CWIN), sugar transport proteins (STP), and sugar will eventually be exported transporters (SWEET) play important roles in plant-pathogen interactions. However, there are contradictory findings and conclusions in the literature. Further studies on microbial sugar metabolism and transport in plant-pathogen interactions are needed.

A systematic review about biological control of phytopathogenic Phytophthora cinnamomi

Darling de Andrade Lourenco et al.

Summary: In this study, a systematic review was conducted on alternative methods for the biocontrol of Phytophthora in general and P. cinnamomi in particular. The results suggested that fungal species of the Trichoderma genus, such as T. harzianum, T. virens, and T. asperellum, as well as bacterial species of the Bacillus genus, show promising potential for controlling various Phytophthora species.

Induced biosynthesis of fengycin and surfactin in a strain of Bacillus amyloliquefaciens with oomyceticidal activity on zoospores of Phytophthora capsici

Nancy Ley-Lopez et al.

Summary: A potential alternative to chemical products for controlling Phytophthora capsici in vegetables is the use of antimicrobial metabolites synthesized in Bacillus species. This study induced the biosynthesis of lipopeptides in Bacillus amyloliquefaciens and evaluated their oomyceticidal effect on P. capsici. The lipopeptides fengycin and surfactin were identified and quantified, and they showed 100% germination inhibition on P. capsici zoospores.

Reactive oxygen species in plants: an invincible fulcrum for biotic stress mitigation

Shaily Tyagi et al.

Summary: Climate change has increased the incidence of pests and pathogens on plants, leading to a need for effective management strategies. Plants respond to stresses by regulating cellular mechanisms through complex signaling networks. Reactive oxygen species (ROS) play a crucial role in maintaining normal plant activities and improving stress management. This review explores the signaling and management of ROS during oxidative bursts caused by plant interactions with pathogens and herbivores. The findings highlight the molecular changes and important roles of ROS in phyto-pathogen/herbivore interactions, providing insights into tackling biotic stresses and developing stress management strategies.

Effect and Response of Quercus ilex subsp. ballota [Desf.] Samp. Seedlings From Three Contrasting Andalusian Populations to Individual and Combined Phytophthora cinnamomi and Drought Stresses

Bonoso San-Eufrasio et al.

Summary: The study revealed that Quercus ilex exhibits population-dependent responses to Phytophthora cinnamomi and drought stress, with damage and mortality greater under combined stresses. Proteomic analysis showed differences in protein profiles among populations under individual and combined stresses, with photosynthetic proteins mainly downaccumulated and stress-responsive proteins upaccumulated. Variable proteins were identified as potential markers for resilience in Q. ilex.
