Abstract

A new study reports creation of spliceosomal introns in multiple related fungal species by proliferation of cryptic elements. Resonances to a case in unrelated algae suggest such elements hold general answers to long-standing mysteries of intron evolution.

摘要

一项新的研究报告称，通过隐匿元件的增殖，在多个相关真菌物种中创造了剪接体内含子。与一种不相关藻类的案例的共鸣表明，这些元件普遍解答了内含子进化的长期谜团。
