rikkakasviyhteisöjen

Rikkakasviyhteisöjen (RCK) are symbiotic associations between plants and fungi that are crucial for the health and productivity of many plant species. These associations are characterized by the presence of specialized fungal structures called arbuscules within the plant root cells. The fungi involved in RCK are typically members of the Glomeromycota phylum, which includes the genera Glomus and Acaulospora.

The primary function of RCK is to enhance the nutrient uptake of the host plant. The fungi in these associations have the ability to fix atmospheric nitrogen, converting it into a form that plants can use. Additionally, they improve the plant's ability to absorb phosphorus and other essential minerals from the soil. This mutualistic relationship is beneficial for both the plant and the fungus, as the plant provides the fungus with carbohydrates produced through photosynthesis.

RCK are found in a wide range of plant species, including many economically important crops such as rice, wheat, and soybeans. The presence of RCK can significantly increase the yield and quality of these crops. However, the specific requirements and optimal conditions for the establishment and functioning of RCK can vary among different plant species and fungal strains.

The study of RCK has gained attention in recent years due to their potential role in sustainable agriculture and the development of plant growth-promoting fungi. Understanding the mechanisms underlying these associations can lead to the identification of strategies to enhance crop productivity and resilience to environmental stresses.
