RT   and growth by a conserved mechanism that modulates hormone signaling.";

CC   -!- FUNCTION: Involved in the regulation of xylem development and growth.
CC       May regulate secondary wall formation during vascular development by
CC       modulation of brassinosteroid, gibberellin and auxin hormone signaling
CC       pathways. {ECO:0000269|PubMed:24567189}.

CC   -!- TISSUE SPECIFICITY: Expressed in vascular tissues of cotyledons,
CC       rosette leaves, sepals, petals, anther filaments. Expressed in roots,
CC       inflorescence stems and developing seeds.
CC       {ECO:0000269|PubMed:24567189}.
CC   -!- DISRUPTION PHENOTYPE: Collapsed xylem vessels in the inflorescence
CC       stems. {ECO:0000269|PubMed:24567189}.
CC   -!- MISCELLANEOUS: Plants overexpressing VUP1 exhibit severe dwarfism with
CC       extreme short and round shaped organs, and display extreme longevity
CC       before senescence. {ECO:0000269|PubMed:24567189}.
