Optimizing ABA-based chemically induced proximity for enhanced intracellular transcriptional activation and modification response to ABA.

Sci China Life Sci

December 2024

Jilin Province Engineering Laboratory of Plant Genetic Improvement, College of Plant Science, Jilin University, Changchun, 130062, China.

Abscisic acid (ABA)-based chemically induced proximity (CIP) is primarily mediated by the interaction of the ABA receptor pyrabactin resistance 1-like 1 (PYL1) and the 2C-type protein phosphatase ABI1, which confers ABA-induced proximity to their fusion proteins, and offers precise temporal control of a wide array of biological processes. However, broad application of ABA-based CIP has been limited by ABA response intensity. In this study, we demonstrated that ABA-induced interaction between another ABA receptor pyrabactin resistance 1 (PYR1) and ABI1 exhibited higher ABA response intensity than that between PYL1 and ABI1 in HEK293T cells.

Article Synopsis
  • N-methyladenosine (mA) is a key post-transcriptional marker that regulates biological functions in plants through various pathway components, including writers, erasers, and readers.
  • A study identified over 4000 mA pathway components across 154 plant species and found that while the number of writers is conserved, the ALKBH and YTH families showed significant expansion.
  • The research also explored the expression levels and roles of specific mA sites in gene regulation, revealing that certain conserved mA sites negatively impacted the expression of other genes, contributing to our understanding of plant evolution and function.

Background: In mammals, amino acid metabolism has evolved to control immune responses. Tryptophan (Trp) is the rarest essential amino acid found in food and its metabolism has evolved to be a primary regulatory node in the control of immune responses. Celiac disease (CeD) is a developed immunological condition caused by gluten intolerance and is linked to chronic small intestine enteropathy in genetically predisposed individuals.
