Plant Toll/interleukin-1 receptor (TIR) domains function as NADases and ribosyl-transferases generating second messengers that trigger hypersensitive responses. TIR-X (TX) proteins contain a TIR domain with or without various C-terminal domains and lack the canonical nucleotide-binding site and leucine-rich repeat domain. In a previous study, we identified an Arabidopsis thaliana activation-tagging line with severe growth defects caused by the overexpression of the AtTX12 gene.

The root epidermis of Arabidopsis (Arabidopsis thaliana) consists of two distinct cell types: hair (H) cells and non-hair (N) cells, whose patterning is regulated by a network of genes. Among these, the WEREWOLF (WER) gene, encoding an R2R3 MYB transcription factor, acts as a master regulator by promoting the expression of key downstream genes, such as GLABRA2 and CAPRICE. However, the mechanisms controlling WER expression have remained largely unexplored.

Polyimide membranes have been widely investigated in gas separation applications due to their high separation abilities, excellent processability, relatively low cost, and stabilities. Unfortunately, it is extremely challenging to simultaneously achieve both improved gas permeability and selectivity due to the trade-off relationship in common polymer membranes. Diamine modification is a simple strategy to tune the separation performance of polyimide membranes, but an excessive loss in permeability is also generally observed.
