Накратко на български

Взаимодействието между бактерията Micromonospora cremea и граха се изследва, за да се види как микроорганизмите помагат на растението да расте при наличие на тежки метали. Това помага за разработването на устойчиви земеделски практики и по-добро управление на почвите.

Unraveling the molecular dialogue in microbial-assisted plant growth in the presence of heavy metals

Agriculture is currently confronting an increasing human population and limitations of soil use due to, among other reasons, pollution levels above food safety threshold values. Some agricultural practices increase the heavy metal (HM) content of agricultural soils, representing an important threat for human health and ecosystems. The use of microorganisms (bacteria, fungi) as plant growth promoters has been increasingly studied for a number of years, but it has only recently been proposed to improve plant HM tolerance. Regrettably, plant-microorganism-pollutant interactions are still poorly understood, and the molecular underlying mechanisms are mostly unknown. The abovementioned challenges for agricultural production require the study of these mechanisms to better promote a more efficient and sustainable agriculture. Deciphering the molecular interactions between plants and microorganisms under HM stress is necessary to provide new pathways for improved soil management. This project addresses a crucial objective in food security, i.e. the development of sustainable agricultural practices to control potentially adverse effects of HM exposure on plant health and growth. Objectives of the project: - To demonstrate the plant growth promotion capacity of the actinobacterial strain Micromonospora cremea CR30T on a highly valuable crop (Pisum sativum) in the presence and absence of HMs - To identify genes implicated in P. sativum response to the presence of M. cremea CR30T - To identify genes implicated in P. sativum response to HMs - To identify genes implicated in P. sativum response to HMs in the presence of M. cremea CR30T - To determine HM accumulation in P. sativum tissues in the presence and absence of M. cremea CR30T.

Цел на проекта

Agriculture is currently confronting (i) an increasing human population and (ii) limitations of soil use due to, among other reasons, pollution levels above food safety threshold values. Some agricultural practices increase the heavy metal content (HM) of agricultural soil, representing an important threat for the European agricultural development. The use of microorganisms as plant growth promoters has been increasingly studied for a number of years, but it has only recently been proposed to improve plant metal tolerance. Regrettably, plant-microorganism-pollutant interactions are still poorly understood and the molecular underlying mechanisms are mostly unknown. The abovementioned challenges for agricultural production require the study of these mechanisms to better promote a more efficient and sustainable agriculture. This project will venture into new unchartered territory by focusing on the molecular interactions between a probiotic actinobacterium (Micromonospora cremea) and its host, Pisum sativum (garden pea), in the presence of HMs. We will evaluate the capacity of M. cremea CR30 to improve plant tolerance to HM polluted soils, in addition to unraveling the molecular dialogue during the first and late steps of their interaction. Early step interactions are crucial in plant promotion and protection against external stresses, like pollution by HM. Here, we propose the use of new -omic technologies to study these molecular interactions between plants and microorganisms under metal stress, providing a new pathway for an improved soil management. This project addresses a crucial objective in food security, the development of sustainable agricultural practices to control potentially adverse HM effects on plant health.
