This paper identifies AtLa1 as an essential RNA-binding factor for Arabidopsis telomerase function, revealing its role in telomerase complex assembly and highlighting evolutionary conservation with yeast and ciliate proteins.

The paper analyzes chromatin organization in the early land plant Marchantia polymorpha, revealing an ancestral role of H3K27me3 in transposon silencing and heterochromatin formation.

This study identifies the minimal functional telomere length in Arabidopsis by analyzing a hypomorphic TERT allele, finding 400 bp as necessary and sufficient for viability.
