Abstract An angiosperm seed is formed by the embryo and endosperm, which are direct products of fertilization, maternal coat. These tissues communicate with each other to ensure synchronized development. After auxin produced in endosperm exported integuments where it drives coat formation. Here, we show that signals back promote its proliferation via steroid hormones brassinosteroids (BR). We BR regulate cell wall-related processes biophysical properties this organ determine rate a manner...
Candida albicans is an opportunistic yeast and a member of the normal human flora that commonly causes infections in patients with any type deficiency immune system. The essential oils have been tested for antimycotic activity pose much potential as antifungal agents. This work investigated oil Cymbopogon winterianus against C. by MIC, MFC time-kill methods. (EO) was obtained hydrodistillation using Clevenger-type apparatus. It fifteen strains albicans. MIC determined microdilution method...
Trichophyton rubrum is one of the most common fungi causer dermatophytosis, mycosis that affect humans and animals around world. Researches aiming new products with antifungal activity become necessary to overcome difficulties on treatment these infections. Accordingly, this study aimed investigate essential oil from Cymbopogon winterianus against dermatophyte T. rubrum. The screening was performed by solid medium diffusion method 16 strains, minimum inhibitory concentration (MIC) fungicide...
Abstract Seed development in angiosperms starts with double fertilization, where two paternal sperm cells fertilize the maternal gametes. This leads to formation of embryo and endosperm. These fertilization products are enveloped by maternally-derived seed coat, which is inhibited prior Polycomb Repressive Complex 2 (PRC2). complex deposits repressive histone mark H3K27me3, whose removal necessary for coat formation. Here, we show that JUMONJI-type (JMJ) demethylases expressed coats...

A Floresta Estacional Semidecidual Montana no Pico do Jabre, localizada estado da Paraíba, Brasil, o ponto mais alto Nordeste setentrional com 1.197 m, a 360 km mar foi avaliada objetivo de caracterizar estrutura fitossociológica componente lenhoso. Em 36 parcelas sistemáticas 10x50 foram medidas as alturas e diâmetros dos indivíduos DAP> 4,8 cm. Amostras botânicas coletadas, durante cinco anos depositadas Herbário Universidade Federal Paraíba (JPB). Foram amostrados 2050 distribuídos em...
Traditional communities, such as quilombos, often make use of a variety plant resources. This study aims to describe and classify the state conservation woody species surviving forest remnants used by quilombo community Ipiranga, on Southern coast Paraíba in northeastern Brazil. Data were obtained through semi-structured interviews using snowball sampling method. Plant availability nature was determined phytosociological survey. Species grouped into categories their value (UV), priority...
Seasonal montane forests are found in a variety of land elevation, climatic conditions, isolation and fragility. This study aims to establish the floristic composition assess species contribution from regional woody communities Pico do Jabre seasonal forest (06° 02'12'' 08° 19'18'' S 34° 45'12'' e 38° 45'45''W). area contains highest elevation (1197 m) Northeast Brazil. A survey was carried out during three years, monthly vouchers were incorporated into University Paraiba (JPB) herbarium....
In the course of preparing taxonomic revision Rhamnaceae Brazil for Catalogue Plants and Fungi Brazil, several problems related to typification were detected. Taxonomic observations nomenclatural notes are here reported based on analysis type material, as well classic recent collections, in 63 herbaria abroad, together with analyses virtual herbaria. Types sought, majority which located studied. Eleven synonymies, 37 lectotypes one neotype designated defined seven genera family.
Este trabalho apresenta um levantamento florístico da família Melastomataceae no Litoral Sul do estado Paraíba. A área de estudo abrangeu os municípios Conde, Pitimbu e Alhandra, localizados na microrregião Paraibano, incluindo limites APA Tambaba, uma unidade conservação uso sustentável, Bioma Mata Atlântica. está representada por seis gêneros dez espécies: Clidemia biserrata DC., C. hirta (L.) D. Don, Comolia villosa (Aubl.) Triana, Henriettea sp., Miconia albicans (Sw.) M. amoena ciliata...
A vegetação inserida em áreas urbanas é fundamental para a manutenção do microclima, habitat animais, redução da poluição sonora, melhoria qualidade de vida população. O diagnóstico das espécies nesse ambiente importante o manejo e conservação dessa vegetação. Universidade Federal Paraíba - UFPB um espaço intra-urbano composta por arborizadas com fragmentos Mata Atlântica. Dessa forma objetivo deste estudo diagnosticar quantitativamente qualitativamente as arbóreas local, contribuindo...

O estudo da família Rhamnaceae é parte do levantamento "Flora Serra Cipó, Minas Gerais, Brasil". Esta está representada naquela área pelos seguintes gêneros, com o respectivo número de espécies: Crumenaria (3), Gouania (1), Reissekia Rhamnidium (1) and Rhamnus (1). São apresentadas chaves para descrições e ilustrações.
Este artigo analisa o subsistema termodinâmico, do Campus I da Universidade Federal Paraíba UFPB, correlacionando com as suas diversas formas de cobertura solo. Para a realização coleta dados (temperatura e umidade relativa ar) foram utilizados termohigrometros Hobos®. As medições realizadas no período estiagem (janeiro março) chuvoso (junho agosto), em nove pontos. O nível conforto térmico foi avaliado pelo Índice Thom classificado acordo Santos (2011). Os tipos solo cada ponto monitorado...
A fragmentação da vegetação inserida no ambiente urbano, decorrente ocupação desordenada do solo, gera transformações significativas na dinâmica dos fatores termodinâmicos. Este trabalho analisa o sistema microclimático subsistema termodinâmico Universidade Federal Paraíba, em diferentes níveis de fragmentação. Foram realizadas coletas dados temperatura e umidade relativa ar, três pontos com fragmentações, durante os períodos: chuvoso (março a agosto) seco (setembro fevereiro). Também foi...
