In the present work we investigated the movement pattern of Spartocera (= Corecoris) dentiventris (Berg) (Hemiptera: Coreidae) adults through the mark-release-recapture method in an experimental tobacco crop (Nicotiana tabacum L., Solanaceae) in Porto Alegre, RS, Brazil. We marked 217 specimens from August 1999 to April 2000. Females moved 2.94 +/- 0.198 times and males 1.46 +/- 0.171 times amo...

Quantitative analyses of sexual expression show extensive interspecific variation in the strength of andromonoecy (proportions of hermaphroditic and staminate flowers) among Solanum species in the monophyletic section Lasiocarpa. The roles of phenotypic plasticity and inter- and intra-inflorescence architecture in the diversification of andromonoecy within this small clade were analyzed. Four s...

Plant resistance conferred by nucleotide binding site (NBS)-encoding resistance genes plays a key role in the defense against various pathogens throughout the entire plant life cycle. However, comparative analyses for the systematic evaluation and determination of the evolutionary modes of NBS-encoding genes among Solanaceae species are rare. In this study, 447, 255, and 306 NBS-encoding genes ...

13 We present a higher-level phylogenetic hypothesis for the diverse neotropical butterfly subfamily Ithomiinae, inferred from one of 14 the largest non-molecular Lepidoptera data sets to date, including 106 species (105 ingroup) and 353 characters (306 informative) 15 from adult and immature stage morphology and ecology. Initial analyses resulted in 1716 most parsimonious trees, which were 16 ...

Chemical Investigation of leaves Cestrum nocturnum (Solanaceae) led to the isolation a compound which was characterized as 1-acetylbutane 1,2(S), 3(S)-4-tetraol or 1-acetyl D-erythritol (I) based on spectroscopic studies.

The availability of an entire plant genome allows for many new insights into areas such as chromosome architecture, gene transfer from organelles, frequency and position of transposable elements, and evolutionary relationships. The task of sequencing an entire genome still remains formidable, however the relative ease and precision of sequencing and the efficiency of subsequent annotation and o...

According to the latest phylogenetic and cytogenetic results, Larnax and Deprea should be merged in order to form a natural group. Consequently, we propose 32 combinations of Larnax species names under Deprea: Depreaabra-patriciae (S.Leiva & Barboza) S.Leiva & Deanna, comb. nov., Depreaaltomayoensis (S.Leiva & Quip.) Barboza & Deanna, comb. nov., Depreaandersonii (N.W.Sawyer) Deanna & S.Leiva, ...

During their development, leaves progress through a highly controlled yet flexible developmental program. Transcription factors from the CIN-TCP family affect leaf shape by regulating the timing of leaf maturation. Characterization of mutants in the tomato (Solanum lycopersicum) CIN-TCP gene LANCEOLATE (LA) led us to hypothesize that a threshold LA-like activity promotes leaf differentiation. H...

discovery of 13c nmr and its application in the biosynthetic pathways prompted the synthesis of several 13c labelled precursors. to investigate the metabolism of phenyllactic acid in the solanaceae family, the double labelled acid was synthesized from barium carbonate (13c) and sodium syanide (13c)
