O uso da semente de tremoço como fertilizante azotado
Teixeira, Gonçalo; Katrochan, Kay; Varennes, A.; Martins, João Neves; Stuetzel, HartmutWe studied the use of lupine seeds as fertilizer to provide a slow release N source. The main objective was to compare different strategies to apply lupine seeds (Lupinus angustifolius L. cv. Azuro and cv. Boruta) as N-fertilizers for a white cabbage crop (Brassica oleracea capitata L. cv. Impuls). Since during the germination process the seedlings use storage carbohydrates as an energy source by respiration, t...
The distinctive population structure of Colletotrichum species associated with ...
Oliveira, Helena; Talhinhas, Pedro; Martins, João Neves; Sreenivasaprasad, SurapareddyAnthracnose (Colletotrichum spp.) is an important disease of olive fruits. Diversity and biogeographic relationships of the olive anthracnose pathogens in the Algarve (Portugal) were investigated, along with host association patterns and disease levels during 2004–2007, to test the hypothesis that this region is a host–pathogen diversity hot spot. Diverse Colletotrichum acutatum and Colletotrichum gloeosporioid...
Agrobacterium-mediated transformation and insertional mutagenesis in Colletotri...
Oliveira, Helena; Talhinhas, Pedro; Martins, João Neves; Muthumeenakshi, S.; Sreenivasaprasad, S.Colletotrichum acutatum is a cosmopolitan pathogen causing economically important diseases known as anthracnose on a wide range of hosts. This fungus exhibits varied pathogenicity lifestyles and the tools essential to understand the molecular mechanisms are still being developed. The transformation methods currently available for this species for gene discovery and functional analysis involve protoplast transfo...
Collection of Lupinus angustifolius L. germplasm and characterisation of morpho...
Talhinhas, Pedro; Leitão, José; Martins, João NevesLupinus angustifolius L. is a Mediterranean species, domesticated in the 20th century, representing an important grain legume crop in Australia and other countries. This work is focused on the collection of wild germplasm and on the characterisation of morphological and molecular diversity of germplasm accessions. It reports the collection of 81 wild L. angustifolius accessions from the South and Centre of Port...
Molecular and phenotypic analyses reveal association of diverse Colletotrichum ...
Oliveira, Helena; Talhinhas, Pedro; Sreenivasaprasad, S.; Martins, João NevesAnthracnose (Colletotrichum spp.) is an important disease causing major yield losses and poor oil quality in olives. The objectives were to determine the diversity and distribution pattern of Colletotrichum spp. populations prevalent in olives and their relatedness to anthracnose pathogens in other hosts, assess their pathogenic variability and host preference, and develop diagnostic tools. A total of 128 Colle...
