1. Evolução e desenvolvimento de gavinhas em Bignonieae (Bignoniaceae) / Evolution and development of tendrils in Bignonieae (Bignoniaceae)
Angiosperm leaves have undergone major functional and structural modifications over time, and currently exist in a wide diversity of forms, sizes, and arrangements. For example, in the tribe Bignonieae (Bignoniaceae), leaves are generally 2-3-foliolated, and the terminal leaflet is often modified into tendrils.These tendrils present varied morphologies (simp

3. A Floricaula/Leafy gene homolog is preferentially expressed in developing female cones of the tropical pine Pinus caribaea var. caribaea
In angiosperms, flower formation is controlled by meristem identity genes, one of which, FLORICAULA (FLO)/LEAFY (LFY), plays a central role. It is not known if the formation of reproductive organs of pre-angiosperm species is similarly regulated. Here, we report the cloning of a conifer (Pinus caribaea var. caribaea) FLO/LFY homolog, named PcLFY. This gene h

4. EgLFY: o homólogo em Eucalyptus grandis do gene LEAFY de Arabidopsis é expresso em tecidos vegetativos e reprodutivos
O gene EgLFY, clonado de Eucalyptus grandis, possui homologia de seqüência com o gene de identidade meristemática LEAFY (LFY) de Arabidopsis e FLORICAULA (FLO) de Antirrhinum. EgLFY é, preferencialmente, expresso nos órgãos florais em desenvolvimento de eucalipto, obedecendo a um padrão similar ao descrito para o gene LFY de Arabidopsis. Experimentos

5. NEEDLY, a Pinus radiata ortholog of FLORICAULA/LEAFY genes, expressed in both reproductive and vegetative meristems
The LEAFY/FLORICAULA genes from Arabidopsis and Antirrhinum are necessary for normal flower development and play a key role in diverse angiosperm species. A homologue of these flower meristem-identity genes, NEEDLY (NLY), has been identified in Pinus radiata. Although the NLY protein shares extensive sequence similarity with its angiosperm counterparts, it i

6. VFL, the Grapevine FLORICAULA/LEAFY Ortholog, Is Expressed in Meristematic Regions Independently of Their Fate1
The flowering process in grapevine (Vitis vinifera) takes place in buds and extends for two consecutive growing seasons. To understand the genetic and molecular mechanisms underlying this process, we have characterized grapevine bud development, cloned the grapevine FLORICAULA/LEAFY (FLO/LFY) ortholog, VFL, and analyzed its expression patterns during vegetat

7. NFL, the tobacco homolog of FLORICAULA and LEAFY, is transcriptionally expressed in both vegetative and floral meristems.
The homologous genes FLORICAULA (FLO) of Antirrhinum and LEAFY (LFY) of Arabidopsis regulate the formation of determinate floral meristems. Transcripts of these single-copy genes are confined to floral meristems and some floral organs as well as to the leaflike bracts that subtend Antirrhinum flowers. Based on these observations, we hypothesized that the tra

8. Down-regulation of RFL, the FLO/LFY homolog of rice, accompanied with panicle branch initiation
FLORICAULA (FLO) of Antirrhinum and LEAFY (FLY) of Arabidopsis regulate the formation of floral meristems. To examine whether same mechanisms control floral development in distantly related species such as grasses, we isolated RFL, FLO-LFY homolog of rice, and examined its expression and function. Northern analysis showed that RFL is expressed predomi
