“…We speculate that x = 12 may represent the ancestral chromosome number of the Solanaceae family. Some of these chromosome fusions in Petunia may have occurred only recently, as the Petunia sister taxon Calibrachoa has the karyotype n = x = 9 (reviewed by Stehmann et al 2009). Generally, chromosome fragmentation and fusion are known to happen and represent an important speciation factor in plants.…”

“…Pollination syndromes are suites of floral characters, such as petal color, fragrance, reward production, and morphological traits that are adaptations to specific pollinators. The genus Petunia counts 14 species, all endemic to southern South America (Stehmann et al 2009). Petunia axillaris and Petunia parodii are pollinated by nocturnal hawkmoths, P. inflata is pollinated by solitary bees, and P. exserta displays a typical hummingbird pollination syndrome (Fig.…”

Two linkage maps were constructed for the model plant Petunia. Mapping populations were obtained by crossing the wild species Petunia axillaris subsp. axillaris with Petunia inflata, and Petunia axillaris subsp. parodii with Petunia exserta. Both maps cover the seven chromosomes of Petunia, and span 970 centimorgans (cM) and 700 cM of the genomes, respectively. In total, 207 markers were mapped. Of these, 28 are multilocus amplified fragment length polymorphism (AFLP) markers and 179 are gene-derived markers. For the first time we report on the development and mapping of 83 Petunia microsatellites. The two maps retain the same marker order, but display significant differences of recombination frequencies at orthologous mapping intervals. A complex pattern of genomic rearrangements was detected with the related genome of tomato (Solanum lycopersicum), indicating that synteny between Petunia and other Solanaceae crops has been considerably disrupted. The newly developed markers will facilitate the genetic characterization of mutants and ecological studies on genetic diversity and speciation within the genus Petunia. The maps will provide a powerful tool to link genetic and genomic information and will be useful to support sequence assembly of the Petunia genome.

“…However, no records from these states were found in the databases or in the published literature. The species is a terricolous sciophilous treelet (Agra et al, 2009;Feliciano and Salimena, 2011) found in semi-deciduous seasonal forest (Stehmann et al, 2009), moist upland forest ("brejos de altitude", (Agra et al, 2009)), and shaded areas of coastal forests in the Atlantic forest domain (Feliciano & Salimena, 2011;Stehmann et al, 2014).…”

Reproductive biology of endemic Solanum melissarum Bohs (Solanaceae) and updating of its current geographic distribution as the basis for its conservation in the Brazilian Cerrado

The genus Solanum (family Solanaceae) includes more than 1400 species and has buzz-pollinated flowers with poricidal anthers. The present study aimed to describe the distribution, breeding system and pollination mechanism of Solanum melissarum, a species endemic to Brazil. The study of breeding system was conducted in an urban forest fragment in Jataí, GO. Distribution data were gathered from floristic surveys and digital plant databases. The floral morphology and the pollination mechanism were studied on through field observations and preserved flowers. The breeding system was determined through hand pollination treatments. The species has a distribution only in the Brazilian Atlantic forest coastal, and this study provides the first records of S. melissarum for the state of Goiás. The pendulous flowers have poricidal anthers close to the stigma, with membranous thecae joined by a connective bearing osmophores that attract males of Euglossa cordata bees. As they collect fragrances, the bees press the thecae and pollen is released through a bellows mechanism. Based on the hand-pollination treatments, this species is self-incompatible. Isolated forest fragments may not include enough pollinators to ensure the pollination of plants with specialized systems. However, they are essential for the conservation of species with interesting phytogeographic patterns, such as the vicariance observed in S. melissarum, and for the conservation of regional diversity.Keywords: bellows mechanism, Euglossa cordata, osmophores, self-incompatibility, fragrance collection.Biologia reprodutiva da endêmica Solanum melissarum Bohs (Solanaceae) e atualização da distribuição geográfica atual, como base para a sua conservação no Cerrado Brasileiro Resumo O gênero Solanum (família Solanaceae) inclui mais de 1400 espécies e apresenta polinização vibrátil e flores com anteras poricidas. O estudo tem o objetivo de descrever a distribuição, sistema reprodutivo e o mecanismo de polinização de Solanum melissarum, uma espécie endêmica do Brasil. O estudo da biologia reprodutiva foi conduzido em um fragmento florestal urbano em Jataí, GO. As informações de distribuição foram obtidas através de trabalhos florísticos e de banco de dados digitais de plantas. A morfologia floral e o mecanismo de polinização foram estudados através de observações diretas em campo e em flores preservadas. O sistema reprodutivo foi determinado a partir de tratamentos de polinização manual. A espécie apresentava distribuição somente na Mata Atlântica litorânea brasileira, e este estudo demonstrou o primeiro registro de S. melissarum para o estado de Goiás. As flores são pendentes e com anteras poricidas próximas ao estigma, com tecas membranosas envoltas por um conectivo giboso com osmóforos que atraem machos da abelha Euglossa cordata. Na coleta de fragrâncias, as abelhas pressionam as tecas e o polén é liberado por um mecanismo de fole. Baseado nos tratamentos de polinização manual, a espécie é autoincompatível. Fragmentos florestais isolados podem não incluir p...

Abstract:The experiment was conducted in winter-spring 2015-2016 in Thua Thien Hue to identify different foliar fertilizer for Petunia hybrida having good growth and development, beautiful colors and long lifetime under local conditions. The experiment included four treatments with three kinds of forliar fertilizers-Dau Trau MK 30-10-5, gibberellin 25-10-10 and abscisic acid. The control treatment (T 0 ) used sterilized water without foliar fertilizer. The results showed that all the foliar fertilizers influenced well on growth and development of Petunia hybrida. Dau Trau MK 30-10-5 helped Petunia hybrida have high quality and high value/cost ratio than the others.
