Genetic Diversity and Population Structure of Cowpea (Vigna unguiculata (L.) Wa...
Guimarães, Joana Bagoin; Nunes, Cátia; Pereira, Graça; Gomes, Ana; Nhantumbo, Nascimento; Cabrita, Paula; Matos, José; Simões, FernandaAbstract: 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...
Genome-wide clonal variability in European pear “Rocha” using high-throughput s...
Serra, Octávio; de Sousa, Rui Maia; Guimarães, Joana Bagoin; Matos, José; Vicente, Patricia; de Sousa, Miguel Leão; Simões, FernandaPears (Pyrus) are one of the most economically important fruits worldwide. The Pyrus genus is characterized by a high degree of genetic variability between species and interspecific hybrids, and several studies have been performed to assess this variability for both cultivated and wild accessions. These studies have mostly been limited by the resolving power of traditional molecular markers, although in the rec...
Genetic Diversity and Population Structure of Wild Beets (Beta spp.) from the W...
Veloso, Maria Manuela; Simões-Costa, Maria Cristina; Guimarães, Joana Bagoin; Ribeiro, Carla Marques; Evaristo, Isabel; Espírito-Santo, DalilaIn this work, using simple sequence repeat (SSR) markers, we present new insights into the genetic diversity, differentiation, and structure of Beta vulgaris subsp. maritima of western Iberia and the Azores and Madeira islands and of B. macrocarpa from southern Portugal. B. macrocarpa occurs only in southern Portugal and frequently in sympatry with B. vulgaris subsp. maritima, showing genetic introgression. B. ...

Comparative transcriptomic response of two Pinus species to infection with the ...
Gaspar, Daniel; Trindade, Cândida; Usié, Ana; Meireles, Brigida; Fortes, Ana Margarida; Guimarães, Joana Bagoin; Simões, Fernanda; Costa, Rita LourençoPine wilt disease (PWD) caused by pine wood nematode (PWN), Bursaphelenchus xylophilus, is a serious threat to global forest populations of conifers, in particular Pinus spp. Recently, the presence of PWN was reported in dead Yunnan pine (Pinus yunnanensis) trees under natural conditions. To further understand the potential impact caused by PWN in Yunnan pine populations, a transcriptional profiling analysis wa...
Genetic diversity and structure of the portuguese pear (Pyrus communis L.) germ...
Queiroz, Álvaro; Guimarães, Joana Bagoin; Sánchez, Claudia; Simões, Fernanda; Sousa, Rui Maia; Viegas, Wanda; Veloso, Maria ManuelaA rich heritage of traditional pear varieties is kept in national Portuguese collections. Out of these varieties, “Rocha” dominates national pear production. Although a noticeable phenotypic variation among clones of this variety has been reported, little is known about its genetic variability, as to date molecular studies have been performed on a single “Rocha” clone. Eleven Simple Sequence Repeats (SSR) marke...
