The tomato floral homeotic protein FBP1-like gene, SlGLO1, plays key roles in petal and stamen development
MADS-box transcription factors play important role in plant growth and development, especially floral organ identities. In our study, a MADS-box gene SlGLO1- tomato floral homeotic protein FBP1-like gene was isolated. Its tissue-specific expression profile analysis showed that SlGLO1 was highly expressed in petals and stamens. RNAi (RNA interference) repression of SlGLO1 resulted in floral orga...
متن کاملThe Arabidopsis floral homeotic gene APETALA3 differentially regulates intercellular signaling required for petal and stamen development.
Cell-cell signaling is crucial for the coordination of cell division and differentiation during plant organogenesis. We have developed a novel mosaic analysis method for Arabidopsis, based on the maize Ac/Ds transposable element system, to assess the requirements of individual genes in intercellular signaling. Using this strategy, we have shown that the floral homeotic APETALA3 (AP3) gene has d...
متن کاملFunctional interaction between the homeotic genes fbp1 and pMADS1 during petunia floral organogenesis.
The petunia MADS box floral binding protein (fbp) gene 1 represents a class B homeotic gene determining the identity of second and third floral whorl organs. Suppression of fbp1, which is highly homologous to the Antirrhinum gene globosa and Arabidopsis gene pistillata, results in the conversion of petals to sepals and stamens to carpels. In contrast to fbp1, the petunia homeotic gene pMADS1, e...
متن کاملDifferential expression of two MADS box genes in wild-type and mutant petunia flowers.
We isolated and characterized two flower-specific genes from petunia. The protein products of these genes, designated floral binding protein 1 (FBP1) and 2 (FBP2), are putative transcription factors with the MADS box DNA binding domain. RNA gel blot analysis showed that the fbp1 gene is exclusively expressed in petals and stamen of petunia flowers. In contrast, the FBP1 protein was only detecta...
متن کاملVascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms
Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
