In vitro development of angiosperm floral buds and organs
Plant Cell Tissue and Organ Culture (PCTOC), 1989In the last twenty-five years, young inflorescences, floral buds and individual floral organs of a number of species have been cultured in vitro. There is considerable variability in the requirement of plant growth regulators and nutritional factors for flower development of different species.

IiSVP of Isatis indigotica can reduce the size and repress the development of floral organs
Plant Cell Reports, 2023IiSVP of Isatis indigotica was cloned and its expression pattern was analyzed. Ectopic expression of IiSVP in Arabidopsis could delay the flowering time and reduce the size of the floral organs. SVP (SHORT VEGETATIVE PHASE) can negatively regulate the flowering time of Arabidopsis. In the present work, the cDNA of IiSVP, an orthologous gene of AtSVP in

Development of Floral Organs of the Soy Bean
Botanical Gazette, 19311. The mature flower of the soy bean consists of a calyx tube with five unequal lobes, five distinct petals, ten stamens (nine united and one free), and a single carpel. Both unicellular and multicellular trichomes are found on the calyx and pistil. 2. The flower primordium appears first as a protuberance in the axil of a bract.

Transcript profiling on developing Petunia hybrida floral organs
Sexual Plant Reproduction, 2003The cDNA-AFLP transcript profiling technique was used to analyse gene expression during flower development in Petunia hybrida. Reproductive and vegetative floral organs were sampled at five developmental stages and gene expression profiles were compared.

Early floral development and androecium organization in Fouquieriaceae (Ericales)
Plant Systematics and Evolution, 2005Early floral development with focus on the androecium was studied with the help of scanning electron microscopy and serial microtome sectioning in Fouquieria columnaris and F. splendens. Perianth organs appear in a spiral pattern on the floral apex. The spiral may be a clockwise or anti-clockwise.

AtSAMS regulates floral organ development by DNA methylation and ethylene signaling pathway
Plant Science, 2023S-adenosylmethionine synthase is the key enzyme involved in the biosynthesis of S-adenosylmethionine, which serves as the universal methyl group donor and a common precursor for the biosynthesis of ethylene and polyamines. However, little is known about how SAMS controls plant development.

Morphology and development of floral shoots and organs in certain Zannichelliaceae
Botanical Journal of the Linnean Society, 1977Development of reproductive shoots and associated organs in Vleisia aschersoniana, Althenia filiformis, Lepilaena bilocularis and L. cylindrocarpa (Zannichelliaeeae, sensu Dumortier) has been examined using an epi-illumination technique to provide photographic documentation. Floral shoots share a similar basic developmental pattern.

Initiation patterns of flower and floral organ development in Arabidopsis thaliana
Development, 1996ABSTRACT Sector boundary analysis has been used to deduce the number and orientation of cells initiating flower and floral organ development in Arabidopsis thaliana. Sectors were produced in transgenic plants carrying the Ac transposon from maize inserted between the constitutive 35S promoter and the GUS reporter gene.

Development of the Floral Organs
2007AbstractIt is becoming clear that flower development is a cascade, with flowering time integrators activating floral meristem identity genes which activate floral organ identity genes. The floral organ identity genes themselves encode transcription factors, and are predicted to activate the many structural genes required to form the new organs, as well

Development of floral organ identity: stories from the MADS house
Current Opinion in Plant Biology, 2001Recent studies on AGAMOUS-LIKE2-, DEFICIENS- and GLOBOSA-like MADS-box genes in diverse seed plant species have provided novel insights into the mechanisms by which the identity of the different floral organs is specified during flower development. These advances in understanding may lead to major refinements in the classical ABC model of floral organ ...
