Abstract
Aluminum (Al) toxicity poses a significant challenge for plant production on acidic soils, which constitute approximately 30% of the world's ice-free land. To combat Al toxicity, plants have evolved both external and internal detoxification mechanisms. The zinc-finger transcription factor STOP1 (SENSITIVE TO PROTON RHIZOTOXICITY 1) plays a critical and conserved role in Al resistance by inducing genes involved in both external exclusion and internal detoxification mechanisms. Recent studies have uncovered multiple layers of post-transcriptional regulation of STOP1 and have elucidated mechanisms by which plants sense Al and activate signaling cascades that regulate STOP1 function. This review offers a comprehensive overview of the mechanisms through which STOP1 and its homologs confer Al resistance in plants, with a particular focus on Arabidopsis thaliana and rice. Additionally, we discuss recent advances and future perspectives in understanding the post-transcriptional regulation of STOP1, as well as the Al sensing and signaling pathways upstream of STOP1.
期刊介绍：
Plant Communications is an open access publishing platform that supports the global plant science community. It publishes original research, review articles, technical advances, and research resources in various areas of plant sciences. The scope of topics includes evolution, ecology, physiology, biochemistry, development, reproduction, metabolism, molecular and cellular biology, genetics, genomics, environmental interactions, biotechnology, breeding of higher and lower plants, and their interactions with other organisms. The goal of Plant Communications is to provide a high-quality platform for the dissemination of plant science research.
