ERA1 is essential for meristem growth in Arabidopsis thaliana

Meristematic tissue is essential for plant growth and development, serving as a fundamental component in these processes. However, the regulatory networks and mechanism involved in its function remain inadequately understood. In this study, we investigated the role of the farnesyltransferase ERA1 in the development of plant meristematic tissues through phenotypic analysis, in situ hybridization and cell biology techniques. Our findings revealed that era1-11 mutant exhibited retarded growth and impaired development of meristematic tissues. Moreover, the expression levels of key genes associated with meristematic tissue development, such as WUS, CLV3, PLT, were significantly altered in this mutant. In summary, ERA1 plays a vital role in the development of plant meristematic tissues by participating in multiple signaling pathways, thus contributing new insights into the regulatory network involved in plant meristematic tissue development.
