USDA’s National Plant Germplasm System scientists have systematically gathered and maintained the agricultural plant species that undergird our food system. Just 0.000008 percent of the federal budget, they safeguard our food system worth ~$1.5 trillion. Now at risk after attack by DOGE.
Seed and tuber collections are really, really, REALLY important.

Découverte d’un nouveau compartiment cellulaire chez les plantes
L’origine et l’évolution des compartiments intracellulaires des cellules eucaryotes, c’est-à-dire celles qui possèdent un noyau, restent une énigme.
