- Exploiting legume genetics as a tool for a demand driven improvement in agronomical and nutritional qualityPublication . Gonçalves, Letice; Patto, Maria Carlota; Rubiales, Diego; Bronze, Rosário"This study focuses on improving grass pea (Lathyrus sativus L.), a stress-resilient legume crop known for its adaptability to harsh environments and multi-stress resistance. Grass pea is a nutritious cool-season grain legume capable of withstanding climate change impacts, making it an attractive option for ensuring nutritional security in the face of impending climate challenges. Grass pea is characterized by its wide adaptation to various soils and climates, as well as its tolerance to low temperatures, floods, drought, insects, and diseases. Additionally, grass pea offers high protein content for both human and animal consumption and outperforms other legumes in yield, nitrogen fixation, and salinity tolerance. Despite these advantages, its cultivation has been limited due to relatively low yields and the presence of the neurotoxin β-N-oxalyl-l-α,β-diaminopropionic acid (β-ODAP).(...)"
- Olea europaea: contribution to the valorization of the most important Portuguese olive tree variety ‘Galega vulgar’Publication . Sales, Helia"The olive tree (Olea europaea L., subsp. europaea, var. europaea) has played a prominent role in human civilization for thousands of years. This culture exhibits strategic importance in societies, captivating them with its enduring beauty, culinary significance, and remarkable health benefits, along with the impactful socio-economic relevance, contributing to the rural development of olive-producing regions.(...)"
- The genetics and mechanisms of resistance to powdery mildew and rust in LathyrusPublication . Martins, Davide Coelho"Grass pea (Lathyrus sativus L.) is a cool-season legume crop with considerable economic importance as food, fodder, and forage, particularly in the developing nations of South Asia and Sub-Saharan Africa. This species is considered a promising source of calories and proteins. Given its resilience to adverse abiotic and biotic constraints, it has great potential for expansion in drought-prone and marginal areas. "
- Unravelling the genetic control of Fusarium Oxysporum resistance in Lathyrus sativusPublication . Sampaio, Ana Margarida; Patto, Maria Carlota Vaz; Araújo, Susana; Diego Rubiales"Grass pea (Lathyrus sativus) is an annual grain legume crop cultivated worldwide. Although considered underused, grass pea is an important source of protein for human and animal consumption in particular marginal areas. Furthermore, it is characterized by a remarkable resistance to abiotic stresses, such as drought, and biotic stress, such as particular pests and diseases. However, yield inconsistency due to sensitivity to specific diseases strongly limits its cultivation. One of these diseases is fusarium wilt, caused by the soil-borne fungi Fusarium oxysporum (Fo). Fusarium oxysporum promotes a devastating wilt(...)"
- Unravelling the genetic control of combined biotic/abiotic stress resistance in Phaseolus vulgaris L.Publication . Leitão, Susana T."Common bean (Phaseolus vulgaris L.) is among the most important grain legumes for human consumption worldwide. Portugal has a promising common bean germplasm that resulted from more than five centuries of natural adaptation and farmers’ selection. Nevertheless, limited characterization of this resource hampers its exploitation by breeding programs. To support a more efficient conservation of the national bean germplasm and promote its use in crop improvement, we performed, for the first time, a simultaneous molecular marker and seed and plant morphological characterization of 175 accessions collected from Portuguese mainland and islands traditional bean-growing regions. Most of the Portuguese accessions grouped with the race representatives and wild relatives from the Andean region."
- Exploring maize genetic diversity – a quality-driven perspectivePublication . Alves, Mara Lisa"In Portugal, and to a certain extent, farmers keep growing traditional maize populations known for their bread quality, conserving simultaneously their high genetic diversity. Maize populations, genetically more heterogeneous than commercial hybrid varieties, can evolve and better adapt to a changing broader range of edaphic-climatic conditions. Unfortunately, these maize populations suffer from a real risk of disappearing, due to their characteristic low yields. It is, therefore, desirable to improve their agronomic performance while maintaining their valuable diversity levels.(...)"
- Comparative mapping of disease resistance genes in Lathyrus spp. using model legume genetic informationPublication . Almeida, NunoLathyrus cicera L. (chickling pea) and L. sativus L. (grass pea) have great potential among grain legumes due to their adaptability to inauspicious environments, high protein content and resistance to serious diseases. Lathyrus spp. are considered potential sources of high quality and cheap protein. Nevertheless, due to its past underuse, further activities are required to exploit this potential and to capitalise on the present molecular biology advances on Lathyrus spp. breeding programmes.(...)
