A reference-free pipeline for detecting shared transposable elements from pan-genomes to retrace their dynamics in a species - Genome Biology Background The role of transposable elements (TEs) in host adaptation has gained interest in recent years. Individuals of the same species undergo independent TE insertions, providing genetic variabil...

We are pleased to announce the publication of panREPET, a pipeline that identifies TE insertions shared by groups of individuals.

Nématode: ce ver microscopique ravageur menace les forêts de pins de cette région de France Le nématode, un ver microscopique, a été détecté pour la première fois en France à Seignosse dans les Landes. Un ver ravageur venu d'Amérique du Nord et qui est très dangereux pour les pins.

"Dans les cas extrêmes, le #nématode du pin va provoquer la mort de l’arbre en quelques semaines”, détaille #MélineSaubin, chercheuse en épidémiologie végétale à #UMR-Biogeco @inrae-france.bsky.social.
