Abstract: Cowpea (Vigna unguiculata (L.) Walp.) is currently a legume crop of minor importance in Europe but a highly relevant staple crop in Africa and the second most cultivated legume in Mozambique. In Portugal and Mozambique, cowpea’s phenotypic and genetic variation has been maintained locally by farmers in some areas. We used the molecular markers SSR, SilicoDArT and SNP to analyze the genetic diversity a...

Biodiversity of Root-Nodule Bacteria Associated With the Leguminous Plant Biser...

Vicente, Claudia; Pérez-Fernández, Maria A; Pereira, Graça; Tavares-de-Sousa, Manuel

Biserrula pelecinus is a noteworthy forage legume known for its drought- and acid-resistant properties and nitrogen-fixing ability that forms an extremely specific symbiotic relationship with bacteria from genera Mesorhizobium. To investigate the biodiversity of root- nodule bacteria associated with B. pelecinus, a total of 88 bacterial strains were examined using repYpolymerase chain reaction amplifica- tion. ...


Using microbial seed coating for improving cowpea productivity under a low‐inpu...

Rocha, Inês; Souza‐Alonso, Pablo; Pereira, Graça; Ma, Ying; Vosátka, Miroslav; Freitas, Helena; Oliveira, Rui S.

BACKGROUND Plant‐growth‐promoting rhizobacteria (PGPR) and arbuscular mycorrhizal (AM) fungi have the ability to enhance the growth, fitness, and quality of various agricultural crops, including cowpea. However, field trials confirming the benefits of microbes in large‐scale applications using economically viable and efficient inoculation methods are still scarce. Microbial seed coating has a great potential fo...


Potencialidades do projeto ´Expressa-te!´ para a promoção de sexualidades saudá...

Aragão, Eugénia; Rodrigues, António; Araújo, Rita; Pereira, Graça; Vilaça, Teresa

No âmbito da disciplina de Cidadania e Desenvolvimento (CD) foi dinamizado nas turmas do 7ºano da escola o projeto intitulado “Expressa-te!”, que tem como finalidade desenvolver nos alunos competências na área da comunicação e das emoções, competências que estão descritas na estratégia de educação para a cidadania e no perfil dos alunos à saída da escolaridade obrigatória. O projeto surgiu da importância atribu...


A pluralidade do olhar de alunos/as do 9º ano sobre a sexualidade e género em o...

Aragão, Eugénia; Matos, Henrique; Lago, Alexandra; Pereira, Graça; Vilaça, Teresa

Foucault associa à sexualidade um dispositivo histórico, constituído como uma criação discursiva institucional, cuja função seria o controle dos indivíduos e das populações. Na sua perspetiva, a estimulação dos corpos, a intensificação dos prazeres, a formação dos conhecimentos, os controles e as resistências encadeiam-se uns nos outros segundo algumas grandes estratégias de ‘saber’ e ‘poder’ que atuando sobre ...


Psychological morbidity, social support, and relationship intimacy in pregnant ...

Costa, Eleonora C. V.; Moreira, Litícia; Castanheira, Eva; Correira, Paulo; Pereira, Graça

Pregnancy can predispose women to stress and depression, with social support and intimacy being protective factors for the development of these disorders. This study evaluated the relationship between stress (various stressors), social support, intimacy and depression in a sample of 169 pregnant women attending the Childbirth Preparation classes. Depressive mood was positively correlated with both stress and sa...


Phytochemical profiling of underexploited Fabaceae species: Insights on the ont...

Barreira, João C.M.; Visnevschi-Necrasov, Tatiana; Pereira, Graça; Nunes, Eugénia; Oliveira, Beatriz

There is an increasing trend towards finding alternative sources of valued phytochemicals due to their diverse potentialities in food industry and pharmaceutical applications. Phenolic compounds, in particular, have been the focus of several profiling reports, but isoflavones characterization has been studied in fewer cases and in a very limited group of plant species. Despite their acknowledged bioactivity, th...

European cowpea landraces for a more sustainable agriculture system and novel f...

Carvalho, Márcia Raquel Gomes de; Bebeli, Penelope J; Pereira, Graça; Egea-Gilabert, Catalina; Lazaridi, Efstathia; Duarte, Isabel; Lino-Neto, Teresa

BACKGROUND: Genetic diversity is fundamental to breeding programs and consequently has an important role in obtaining new varieties. To properly use the genetic diversity present in germplasm collections, a good knowledge of the agro-morphological traits of each accession is needed. The aim of this study was to explore the production capacity of 24 cowpea landraces from southern Europe, through phenotypic chara...

Phylogenetic insights on the isoflavone profile variations in Fabaceae spp.: As...

Visnevschi-Necrasov, Tatiana; Barreira, João C.M.; Cunha, Sara C.; Pereira, Graça; Nunes, Eugénia; Oliveira, Beatriz

Legumes (Fabaceae) are important crops, known as sources of food, feed for livestock and raw materials for industry. Their ability to capture atmospheric nitrogen during symbiotic processes with soil bacteria reduces the need for expensive chemical fertilizers, improving soil and water quality. Several Fabaceae species are acknowledged for the high levels of secondary metabolites. Isoflavones are among the most...
