To identify genes involved in Arabidopsis thaliana petal and stamen organogenesis, we used a gene trap approach to examine the patterns of reporter expression at each stage of flower development of 1765 gene trap lines. In 80 lines, the reporter gene showed petal- and/or stamen-specific expression or lack of expression, or expression in distinct patterns within the petals and/or the stamens, including distinct suborgan domains of expression, such as tissue-specific lines marking epidermis and...

	Secretion trap tagging of secreted and membrane-spanning proteins using Arabidopsis gene traps1 Plant Physiology ; Secreted and membrane-spanning proteins play fundamental roles in plant development but pose challenges for genetic identification and characterization. We describe a "secretion trap" screen for gene trap insertions in genes encoding proteins routed through the secretory pathway. The gene trap

Gene and enhancer trap vectors carrying the [beta]-glucuronidase (GUS) reporter gene were inserted into the poplar genome via Agrobacterium tumefaciens transformation, where they reveal the expression pattern of
	Gene traps: Tools for plant develoopment and genomics Plant Cell ; INTRODUCTION Classical genetic approaches to gene identification rely on disruption of a gene leading to a recognizable phenotype. This approach continues to be an extremely successful one, yielding mutations that result in overt phenotypes reflecting the function of the corresponding gene. Not all

The binary vector contains the promoterless 03-glucuronidase (GUS) reporter gene next to the
	LucTrap Vectors Are Tools to Generate Luciferase Fusions for the Quantification of Transcript and Protein Abundance in Vivo1 Plant Physiology ; Proper plant growth and development strongly rely on the plant's ability to respond dynamically to signals and cues from the intra- and extracellular environment. Whereas many of these responses require specific changes at the level of gene expression, in recent years it has become increasingly
	OsCSLD1, a Cellulose Synthase-Like D1 Gene, Is Required for Root Hair Morphogenesis in Rice1[C][W] Plant Physiology ; Root hairs are long tubular outgrowths that form on the surface of specialized epidermal cells. They are required for nutrient and water uptake and interact with the soil microflora. Here we show that the Oryza saliva cellulose synthase-like D1 (OsCSLD1) gene is required for root hair development,
