Mutations associated with floral organ number in rice
Planta, 1996How floral organ number is specified is an interesting subject and has been intensively studied in Arabidopsis thaliana. In rice (Oryza sativa L.), mutations associated with floral organ number have been identified. In three mutants of rice, floral organ number 1 (fon1) and the two alleles, floral organ number 2-1 (fon2-1) and floral organ number 2-2 ...

The formation of floral organs on the meristem follows on the heels of evocation and overlaps with evocation. The conventional angiosperm flower is made up of four whorls of modified leaves constituting the sterile and fertile parts. The sterile parts consist of an outer whorl of sepals that are usually green and enclose the rest of the flower before ...

Perianth organization and intra‐specific floral variability
Plant Biology, 2008AbstractFloral symmetry and fusion of perianth parts are factors that contribute to fine‐tune the match between flowers and their animal pollination vectors. In the present study, we investigated whether the possession of a sympetalous (fused) corolla and bilateral symmetry of flowers translate into decreased intra‐specific variability as a result of ...

Transformation of floral organs with GFP in Medicago truncatula
Plant Cell Reports, 2000A high frequency of embryogenesis and transformation from all parts of flowers of two lines of Medicago truncatula R-108-1 and Jemalong J5 were obtained. Using this flower system, we obtained transgenic plants expressing promoter-uidA gene fusions as well as the gfp living cell color reporter gene.

The ABC model and the diversification of floral organ identity
Seminars in Cell & Developmental Biology, 2010Broad studies of the ABC program across angiosperms have found that interactions between gene duplication, biochemical evolution, shifts in gene expression and modification of existing identity programs have been critical to the evolution of floral morphology. Several themes can be recognized in this context. First, the original concept of "A" function

Floral organ identity: 20 years of ABCs
Seminars in Cell & Developmental Biology, 2010One of the early successes of the application of molecular genetics to study plant development was the discovery of a series of genes that act together, in an apparently simple combinatorial model, to specify the identity of the different organs of a flower.

Transcriptome data of floral organs for pummelo
2021The plant materials used in this subject were from two cultivars of pummelo (Citrus maxima) that were collected from Rong County, Yulin city, Guangxi province, China. One cultivar is a self-incompatible ‘Shatian’ pummelo. The other cultivar is the ‘Guiyou No.1’ pummelo that was derived from a bud sport variation of ‘Shatian’. Floral organs of ‘Shatian’

Induction on Regeneration of Floral Organs and Sexual Organs
1993The present paper introduces the new progress on induction of regeneration of flower organs and sexual organs in China. It mainly includes four parts: 1. Regeneration of tepals, stamens and ovules in hyacinth. 2. Maturity of the regenerative stamens and ovules. 3. Regeneration of spikelet and pistil of wheat. 4.

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.

The Regulation of Tobacco Floral Organ Initiation
Botanical Gazette, 1980Flower buds of tobacco (Nicotiana tabacum), excised before organ primordia are present or, except for the sepals, determined, will continue normal development and produce all floral organs in a usual sequence when placed on a simple, defined medium lacking growth substances By surgically manipulating organ primordia, it was possible to infer the source
