Abstract: O elevado nível de heterozigose dos parentais utilizados em hibrida es é a principal causa da baixa eficiência dos programas de melhoramento genético do abacaxizeiro em gerar novas cultivares. Por outro lado, os efeitos da autofecunda o s o pouco conhecidos em abacaxi, mas esta estratégia pode proporcionar avan os significativos no melhoramento desta planta. Assim, este trabalho teve como objetivo observar os efeitos da autofecunda o em cultivares de abacaxi. Inflorescências das cultivares Primavera, Perolera, Roxo-de-Tefé, Pérola e Smooth Cayenne foram protegidas antes da antese para possibilitar a ocorrência de autofecunda o. As sementes produzidas foram germinadas em camara de crescimento, utilizando-se como substrato do meio de cultura MS, suplementado com 30 g.L-1 de sacarose e solidificado com 2 g.L-1 de "Phytagel. Durante a germina o, observou-se que cerca de 16% das sementes de 'Roxo-de-Tefé' produziram plantulas albinas. Foram obtidas 43 plantas a partir de 'Primavera', cinco de 'Perolera', onze de 'Roxo-de-Tefé' e nenhuma de 'Pérola' e 'Smooth Cayenne'. Todas as plantas da progênie de 'Primavera' apresentaram folhas sem espinhos nos bordos ("piping"), evidenciando homozigose para esta característica, enquanto na progênie de 'Perolera' três plantas evidenciaram folhas sem espinhos nos bordos e duas com folhas espinhosas, segregando para o caráter espinescência. Na descendência de 'Roxo-de-Tefé', oito plantas apresentaram folhas de cor roxa e três com folhas verdes, com segrega o para a cor da folha, mas todas evidenciaram folhas com espinhos no bordo. As baixas porcentagens de germina o, o crescimento lento e o baixo vigor observados nas plantas em casa de vegeta o, viveiro e campo, evidenciaram a ocorrência de depress o por endogamia nestas fases de desenvolvimento.

Abstract: Hologram QSAR models were developed for a series of 36 inhibitors (29 training set and seven test set compounds) of acetyl/butyrylcholinesterase (AChE/BChE) enzymes, an attractive molecular target for Alzheimer’s disease (AD) treatment. The HQSAR models (N = 29) exhibited significant cross-validated (AChE, q2 = 0.787; BChE, q2 = 0. 904) and non-cross-validated (AChE, r2 = 0.965; BChE, r2 = 0.952) correlation coefficients. The models were used to predict the inhibitory potencies of the test set compounds, and agreement between the experimental and predicted values was verified, exhibiting a powerful predictive capability. Contribution maps show that structural fragments containing aromatic moieties and long side chains increase potency. Both the HQSAR models and the contribution maps should be useful for the further design of novel, structurally related cholinesterase inhibitors.

Abstract: the objective of this research was to evaluate the conservation status and the importance of forest remnants at embu (sp, brazil) for the maintenance of the local plant diversity. a previous classification of the vegetation cover was made with aerial photographs interpretation in order to guide the selection of the forest fragments to be evaluated. in a quick survey, the floristic composition (focused on tree species) and some structural and physiognomic descriptors were recorded to assess the conservation status of the vegetation. nine remaining forests with areas between four and 35 ha were characterized, totaling 140 ha. despite of the short time, 197 species were recorded, being 172 trees typical of the ombrophilous dense forest and some species from the seasonal semideciduous forest. comparing the tree and shrub species between the remaining forests and the morro grande reserve forest - conservation unit located next to the study site - 95 species were found in common and 65 species exclusively occurring at embu forests. moreover, seven threatened species according to the state, national and world red lists were recorded. although these seven species were mostly found in the more mature fragments, some were also found in disturbed ones, indicating that even with the massive occurrence of secondary forests, the maintenance of the forest remnants of embu may help to preserve some species still not protected in the region. the forest can also contribute to protect water and soil resources and to connect native forest patches, facilitating the gene flow of plant and animal species and, consequently, promoting the maintenance of the atlantic forest biodiversity.
