Telomere-to-telomere genome of the model plantPhyscomitrium patens

Abstract

AbstractThe model plantPhyscomitrium patens(P. patens) has played a pivotal role in enhancing our comprehension of plant evolution, growth, and development. However, the current genome harbors numerous intricate regions that remain unfinished and erroneous. To address these issues, we present an exemplary assembly of theP. patensnuclear genome, which incorporates telomeres and centromere regions, thereby establishing it as the telomere-to-telomere (T2T) genome in a non-seed plant. This T2T genome not only dispels the prevailing misconception regarding chromosome number inP. patensbut also provides indispensable resources for conducting in-depth studies in moss genomics and biology.
