However, the influence of polymorphisms in the TDIF peptide motif on activity remains poorly understood. The model plant, <i>Arabidopsis</i> provides a fast and effective tool for assaying the activity of <i>TDIF</i> homologs. Five <i>TDIF</i> homologs from a group of 93 <i>CLE</i> genes in switchgrass (<i>Panicum virgatum</i>), a perennial biomass crop, named <i>PvTDIF-like</i> (<i>PvTDIFL</i>) genes were studied. The expression levels of <i>PvTDIFL1, PvTDIFL3</i> ^<i>MR</i>3, and <i>PvTDIFL3</i> ^<i>MR</i>2 were relatively high and all of them were expressed at the Frontiers in plant scienceInfluence of Switchgrass <i>TDIF-like</i> Genes on <i>Arabidopsis</i> Vascular Development.PMC84965052662020YLPY0262662018PY071Tang JLarkin RMZhang ZLuo LZheng BTian DDu KShi XfalseInfluence of Switchgrass <i>TDIF-like</i> Genes on <i>Arabidopsis</i> Vascular Development.As a member of the CLAVATA3 (CLV3)/EMBRYO SURROUNDING REGION (CLE) family, the dodecapeptide tracheary element differentiation inhibitory factor (TDIF) has a major impact on vascular development in plants.
