The lateral organ boundaries domain transcription factor LBD20 functions in Fusarium wilt Susceptibility and jasmonate signaling in Arabidopsis.
The LATERAL ORGAN BOUNDARIES (LOB) DOMAIN (LBD) gene family encodes plant-specific transcriptional regulators functioning in organ development. In a screen of Arabidopsis (Arabidopsis thaliana) sequence-indexed transferred DNA insertion mutants, we found disruption of the LOB DOMAIN-CONTAINING PROTEIN20 (LBD20) gene led to increased resistance to the root-infecting vascular wilt pathogen Fusari...
متن کاملArabidopsis lateral organ boundaries negatively regulates brassinosteroid accumulation to limit growth in organ boundaries.
Leaves and flowers begin life as outgrowths from the edges of shoot apical meristems. Stem cell divisions in the meristem center replenish cells that are incorporated into organ primordia at the meristem periphery and leave the meristem. Organ boundaries, regions of limited growth that separate forming organs from the meristem, serve to isolate these two domains and are critical for coordinatio...
متن کاملLATERAL ORGAN FUSION1 and LATERAL ORGAN FUSION2 function in lateral organ separation and axillary meristem formation in Arabidopsis.
Plant organs are generated from meristems throughout development. Patterning and elaboration of organ primordia occur as a result of organized cell division and expansion, processes that are likely to be controlled, in part, by meristem-derived signals. Communication between the meristem and lateral organs is crucial for meristem maintenance and organ patterning, and organ boundaries are though...
متن کاملDifferential recruitment of WOX transcription factors for lateral development and organ fusion in Petunia and Arabidopsis.
Petal fusion in petunia (Petunia x hybrida) results from lateral expansion of the five initially separate petal primordia, forming a ring-like primordium that determines further development. Here, we show that MAEWEST (MAW) and CHORIPETALA SUZANNE (CHSU) are required for petal and carpel fusion, as well as for lateral outgrowth of the leaf blade. Morphological and molecular analysis of maw and ...
متن کاملChrysanthemum transcription factor CmLBD1 direct lateral root formation in Arabidopsis thaliana
The plant-specific LATERAL ORGAN BOUNDARIES DOMAIN (LBD) genes are important regulators of growth and development. Here, a chrysanthemum class I LBD transcription factor gene, designated CmLBD1, was isolated and its function verified. CmLBD1 was transcribed in both the root and stem, but not in the leaf. The gene responded to auxin and was shown to participate in the process of adventitious roo...
