Article Synopsis
  • AM fungi improve wheat growth and resilience against stress, leading to increased biomass and grain yield.
  • This study used a mix of phenotypical, molecular, and metabolomic methods to explore the impact of AM symbiosis on wheat's nutritional quality and disease resistance.
  • Results showed that AM fungi enhance mineral nutrition and activate protective pathways in wheat when exposed to the pathogen Xanthomonas translucens.

Article Synopsis
  • - Arbuscular mycorrhizal fungi (AMF) like Gigaspora margarita can host endobacteria, which are crucial for the fungi's development and energy production during the pre-symbiotic phase.
  • - Genome and proteomic analyses reveal endobacteria notably enhance G. margarita's primary metabolism and respiration, increasing these by 50% compared to fungi without endobacteria.
  • - The presence of endobacteria also leads to a lower oxidative stress level in the AMF, impacting fungal growth, calcium signaling, and overall interactions with host plants.

Article Synopsis
  • cAMP is a crucial second messenger in plants, but most understanding comes from pharmacological studies rather than direct evidence.
  • Researchers transformed tobacco BY-2 cells with a cAMP sponge to directly reduce cAMP levels, leading to significant growth inhibition and delayed mitosis.
  • The cAMP deficiency in these cells caused changes in protein expression, enhancing antioxidant systems and affecting proteins related to cell growth and stress response, suggesting that low cAMP levels are perceived as stress in plant cells.
