In temperate forests, the roots of various tree species are colonized by ectomycorrhizal fungi, which have a key role in the nitrogen nutrition of their hosts. However, not much is known about the molecular mechanisms related to nitrogen metabolism in ectomycorrhizal plants. This study aimed to evaluate the nitrogen metabolic response of oak plants when inoculated with the ectomycorrhizal fungus Pisolithus tinctorius.

Article Synopsis
  • Photosynthesis in red grape berries remains a complex topic for scientists, particularly due to the presence of a thick, gas-impermeable skin packed with anthocyanins.
  • Chlorophyll, typically degraded in many fruits, seems to persist in mature red grapes, as indicated by a study isolating chloroplasts from their skin.
  • The research found that while chloroplasts in green grapes focus on biosynthetic reactions, those in ripe grapes may play a crucial role in providing ATP and oxygen for cellular maintenance and respiration.

Article Synopsis
  • - The study explores the diversity of leguminous species (Fabaceae) in East Timor's cashew agroforestry systems, highlighting their importance for both agricultural sustainability and local nutrition.
  • - Fourteen cashew orchards were sampled, identifying around 50 legume species that serve multiple purposes, including food, fodder, and traditional medicine in the local culture.
  • - Certain bean species were highlighted for their nutritional value, as hunger and limited food variety are common in East Timor, emphasizing the role of legumes in improving community health and well-being.

Mycorrhizas are known to have a positive impact on plant growth and ability to resist major biotic and abiotic stresses. However, the metabolic alterations underlying mycorrhizal symbiosis are still understudied. By using metabolomics and transcriptomics approaches, cork oak roots colonized by the ectomycorrhizal fungus Pisolithus tinctorius were compared with non-colonized roots.

Ectomycorrhizas have been reported to increase plant tolerance to drought. However, the mechanisms involved are not yet fully understood. Membranes are the first targets of degradation during drought, and growing evidences support a role for membrane lipids in plant tolerance and adaptation to drought.
