| Systematic studies of angiosperm fossil woods from sediments of the Río Leona Formation were continued. A new morphospecies of Maloidoxylon with affinity to Rosaceae was described and constitutes, together with the fossil pollen from the same strata, the oldest South American fossil with this familial affinity. Nothofagaceae fossil woods are represented by the morphospecies Nothofagoxylon scalariforme Gothan, Nothofagoxylon kraeuseli Boureau et Salard, Nothofagoxylon triseriatum Torres et Lemoigne, Nothofagoxylon ruei Salard and a new morphospecies of Nothofagoxylon. Three of the four subgenera of Nothofagus were recognized in the fossil woods and a new infrageneric affinity for Nothofagoxylon ruei was proposed. The described woods have affinity to extant... |

| BACKGROUND: The aim of our research work was to quantify total flavonoid contents in the leaves of 13 plant species family Asteraceae, 8 representatives of family Lamiaceae and 9 plant species belonging to familyRosaceae, using the multiplex fluorimetric sensor. Fluorescence was measured using optical fluorescence apparatus Multiplex(R) 3 (Force-A, France) for non-destructive flavonoids estimation. The content of total flavonoids was estimated by FLAV index (expressed in relative units), that is deduced from flavonoids UV absorbing properties. RESULTS: Among observed plant species, the highest amount of total flavonoids has been found in leaves ofHelianthus multiflorus (1.65 RU) and Echinops ritro (1.27 RU), Rudbeckia fulgida (1.13 RU) belonging to the... |

| Prunus persica has been proposed as a genomic model for deciduous trees and the Rosaceae family. Optimized protocols for RNA isolation are necessary to further advance studies in this model species such that functional genomics analyses may be performed. Here we present an optimized protocol to rapidly and efficiently purify high quality total RNA from peach fruits (Prunus persica). Isolating high-quality RNA from fruit tissue is often difficult due to large quantities of polysaccharides and polyphenolic compounds that accumulate in this tissue and co-purify with the RNA. Here we demonstrate that a modified version of the method used to isolate RNA from pine trees and the woody plant Cinnamomun tenuipilum is ideal for isolating high quality RNA from the... |

| The rapid identification of the hybrids between sweet cherry (Prunus avium L.) and sour cherry (Prunus cerasus L.) is not easy. In order to resolve this problem, 18 Spanish sweet, sour and duke cherry cultivars were surveyed and characterized using 43 agromorphological descriptors evaluated in flowers, leaves, dormant 1-yr-old shoots, fruits, and trees during 2005 and 2006. Based on quantitative parameters, ANOVA and stepwise discriminant analysis (SDA) were carried out. For qualitative descriptors, statistical comparisons were done by means of the chi-square (χ2) test. As result of the study, two quantitative (titratable acidity and number of lenticels) and six qualitative descriptors (shape of the central and lateral lobes in the internal bracts... |

| ABSTRACT Rugosa rugosa has high tolerance to various stresses; however, the molecular mechanisms of this behavior under adverse conditions are unclear. The objective of this study is to investigate expression patterns of stress-related genes in response to salinity stress. Changes in transcript levels of R. rugose, grown under different salt stress conditions (0, 25, 50, and 100 mM NaCl) over a long exposure period (30 days), have been investigated. In addition, the effects of salt shock stress on seedlings exposed to a high level (200 mM) of NaCl for a relatively short duration (3 h) have also been investigated. Expression levels of selected differentially expressed genes have been determined using relative reverse transcription polymerase chain reaction... |

| In Peach (Prunus persica) several physiological changes, such as woolliness, triggered by chilling injury are involved in major production losses due to cold storage of the fruits during shipping. Additionally, the low level of polymorphisms among peach varieties is an important limitation in the search for new molecular markers that could be associated with economically important traits. Therefore, a functional approach was employed to associate candidate genes with an informative marker in peach. The data was obtained from the results of an in silico analysis of four different cold peach treatments. Thirty two candidate genes were selected that were aligned against Arabidopsis thaliana genomic sequences to design intron-flanking EST-PCR markers. These... |

| The micromorphology of pits in tracheary elements was examined in 35 species representing 29 genera of Rosaceae and related families to evaluate the assumption that angiosperm pits are largely invariant. In most Rosaceae, pit membranes between fibers and tracheids frequently appear to have amorphous thickenings with an irregular distribution. Although these structures are toruslike under the light microscope, observations by electron microscopy illustrate that they represent ‘‘pseudotori’’ or plasmodesmata-associated thickenings. These thickenings frequently extend from the periphery of the pit membrane and form a cap-like, hollow structure. Pseudotori are occasionally found in few Elaeagnaceae and Rhamnaceae and appear to be related to species with... |

| Phylogenetic relationships among 24 genera of Rosaceae subfam. Maloideae and Spiraeoideae are explored by means of a cladistic analysis; 16 morphological and anatomical characters were included in the analysis. Published suprageneric classifications and characters used in these classifications are briefly reviewed. Additionally, some new features are here reported, such as seed shape, presence or absence of endosperm, and number of cell layers in the seed coat and in the endosperm. Parsimony analyses indicate that Eriobotrya and Rhaphiolepis form a well-supported clade that is the sister to the remainder of the subfamily. This result is in agreement with published ITS sequence data. Other clades are not supported, with the exception of the group... |

| Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysiphaceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to determine evolutionary relationships between Podosphaera and its host plants, we used 152 ITS sequences and 69 28S rDNA sequences of Podosphaera for phylogenetic analyses. As a result, Podosphaera was divided into two large clades: clade 1, consisting of the section Podosphaera on Prunus (P. tridactyla s.l.) and subsection Magnicellulatae; and clade 2, composed of the remaining member of section Podosphaera and subsection Sphaerotheca.

| Grapholita molesta (Busck) is one of the major pests of Rosaceae, causing significant damage to buds and fruits. In Southern Brazil, its population density is reduced during Rosaceae dormancy months. The present study evaluated the influence of different photoperiods (L:D) (10:14, 11:13, 12:12, 13:11, 14:10 and 16:8) at 25 ± 1ºC and 60 ± 10% RH on diapause induction of G. molesta eggs, larvae, prepupae, and pupae. The effects of the photoperiod on the life cycle of non-diapausing insects and on the second generation were also assessed. Prepupal diapause was observed only when eggs and neonates (< 12h-old larvae) were exposed to photophases from 10h to 14h long. Development of non-diapausing individuals and those from the second generation tended to be... |

| O objetivo deste trabalho foi determinar os parâmetros biológicos e a tabela de vida de fertilidade da broca-do-morangueiro (Lobiopa insularis) criada em dieta artificial à base de frutos de morangueiro, em condições de laboratório. A duração e a viabilidade média dos períodos embrionário, larval, pupal e ovo-adulto foram de: 4,1±1,5 dias e 80,6%; 22,2±5,0 dias e 60%; 10,8±2,3 dias e 90%; e 37,1±8,8 dias e 43,5%, respectivamente. Os períodos de pré-oviposição, oviposição e pós-oviposição foram de 96±18,9, 133±27,5 e 77±16,3 dias. A longevidade de machos (271±20,7 dias) foi menor do que a de fêmeas (318±14,9 dias). Há potencial de utilização de dieta artificial à base de morangos para a multiplicação da broca-do-morangueiro em laboratório. |

| Para avaliar o potencial de enraizamento de estacas de ramos lenhosos e semilenhosos de cultivares de ameixeira (Carmesin, Gema de Ouro, Januária e Reubennel), utilizou-se aplicação exógena de ácido indolbutírico (IBA) em diferentes concentrações (0; 1000; 2000 e 3000mg L-1). O trabalho foi desenvolvido na Universidade Federal de Lavras (Lavras-MG), em 1997. Após os tratamentos, as estacas foram plantadas em areia lavada e colocadas em casa de sombreamento (lenhosas) e em casa de vegetação (semilenhosas) para enraizar. Foram avaliadas as variáveis porcentagem de enraizamento, número e comprimento de raízes. As maiores porcentagens de enraizamento foram obtidas com estacas semilenhosas da cultivar Januária (54,62%). A aplicação de IBA favoreceu o... |

| Abstract In contrast to ripening of climacteric fruits knowledge, non-climacteric fruits ripening still poorly understood. In this sense, strawberry (Fragaria x ananassa L. Duch) is a high commercial crop and has an expressive world production that has been used as a model study. Thus, the aim of this study was to evaluate the effect on physicochemical and phytochemical characteristics of strawberry Cv. Camiño Real, in four maturation stages (green, white, pink and red) after the ethylene (Etephon®) and brassinosteroid (epi-brassinolide) exogenous spray. The evaluations were carried out at application time (field assay) and after 24h (post-harvest assay). Brassinosteroid application tends to reduce phenolic compounds content mainly in the red stage,... |
