Interplay of auxin, KANADI and Class III HD-ZIP transcription factors in vascular tissue formation.
Class III HD-ZIP and KANADI gene family members have complementary expression patterns in the vasculature and their gain-of-function and loss-of-function mutants have complementary vascular phenotypes. This suggests that members of the two gene families are involved in the establishment of the spatial arrangement of phloem, cambium and xylem. In this study, we have investigated the role of thes...
متن کاملKANADI and class III HD-Zip gene families regulate embryo patterning and modulate auxin flow during embryogenesis in Arabidopsis.
Embryo patterning in Arabidopsis thaliana is highly affected when KANADI or Class III HD-Zip genes are compromised. Triple loss-of-function kan1 kan2 kan4 embryos exhibit striking defects in the peripheral-central axis, developing lateral leaf-like organs from the hypocotyls, whereas loss of Class III HD-Zip gene activity results in a loss of bilateral symmetry. Loss of KANADI activity in a Cla...
متن کاملRoles for Class III HD-Zip and KANADI genes in Arabidopsis root development.
Meristems within the plant body differ in their structure and the patterns and identities of organs they produce. Despite these differences, it is becoming apparent that shoot and root apical and vascular meristems share significant gene expression patterns. Class III HD-Zip genes are required for the formation of a functional shoot apical meristem. In addition, Class III HD-Zip and KANADI gene...
متن کاملRadial Patterning of Arabidopsis Shoots by Class III HD-ZIP and KANADI Genes
BACKGROUND Shoots of all land plants have a radial pattern that can be considered to have an adaxial (central)-abaxial (peripheral) polarity. In Arabidopsis, gain-of-function alleles of PHAVOLUTA and PHABULOSA, members of the class III HD-ZIP gene family, result in adaxialization of lateral organs. Conversely, loss-of-function alleles of the KANADI genes cause an adaxialization of lateral organ...
متن کاملATHB4 and HAT3, two class II HD-ZIP transcription factors, control leaf development in Arabidopsis
In response to plant proximity or canopy shade, plants can react by altering elongation growth and development. Several members of the class II homeodomain-leucine zipper (HD-ZIPII) transcription factor family have been shown to play an instrumental role in the responses to shade. HD-ZIP members of the class III (HD-ZIPIII), by contrast, are involved in basic patterning processes. We recently s...
