The disclosure provides nucleic acid constructs that include a TPR-domain suppressor of STIMPY (TSS) promoter operably linked to an isopentenyl-transferase 7 (IPT7) coding sequence. The introduction of such a construct into a plant or plant cell generates transgenic plants having increased root mass and greater carbon sequestration capacity. Plants generated using the methods are provided. Such plants can include other desirable traits. L'invention concerne des constructions d'acides nucléiques qui comprennent un suppresseur de domaine TPR de promoteur STIMPY (TSS) fonctionnellement lié à une séquence de codage d'isopentényl-transférase 7 (IPT7). L'introduction d'une telle construction dans une plante ou une cellule végétale génère des plantes transgéniques ayant une masse racinaire accrue et une plus grande capacité de séquestration de carbone. L'invention concerne également des plantes générées à l'aide des procédés. De telles plantes peuvent comprendre d'autres caractères souhaitables.
