Assessing the diversity of sea beet (Beta vulgaris L. ssp. maritima) populations
Ascarini, F.; Nóbrega, H. G.M.; Leite, I. S.; Freitas, G.; Ragonezi, C.; Zavattieri, M. Amely; Carvalho, M. A. A. Pinheiro deBeta vulgaris L. subsp. maritima (L.) Arcang., sea beet, is a morphologically and genetically variable species, belonging to beet primary gene -pool. This crop wild relative is a valuable genetic resource for resistance improvement in beets and could play an important role in crop yield sustainability. Eleven Madeiran sea beet populations were characterized using morphological descriptors and genetic markers. O...
Monitoring system and in situ conservation of endemic and threatened Beta patul...
Nóbrega, H.; Freitas, G.; Zavattieri, M. A.; Ragonezi, C.; Frese, L.; Carvalho, M. A. A. Pinheiro det Madeira Archipelago is a hotspot for crop wild relatives (CWR) of crop cultures. Some of these CWR are present in very specific environments, such as, in Ponta de Sa˜o Lourenc¸o or Desertas Islands. One such species is Beta patula Aiton, a Critically Endan gered species which belongs to the Gene Pool 1b of cultivated beets. A continuous effort has been devel oped for its ex situ conservation through the stora...
Fatty acid composition, TLC screening, ATR-FTIR analysis, anti-cholinesterase a...
Nunes, N.; Rosa, G. P.; Ferraz, S.; Barreto, Maria Carmo; Carvalho, M. A. A. Pinheiro deThree macroalgae collected at Madeira Island were included in this study to determine their potential for drug, nutraceutical, food, or supplement application. Fatty acid content was higher in Zonaria tournefortii (12.32 mg g−1 dw) with 16.58% of PUFAs, eicosapentaenoic acid (C20:5ω3), and arachidonic acid (20:4ω6) having concentrations of 2.59 and 1.17%, respectively. The anti-thrombogenic and anti-atherogenic...
Nutraceutical potential of Asparagopsis taxiformis (Delile) Trevisan extracts a...
Nunes, N.; Valente, S.; Ferraz, S.; Barreto, Maria Carmo; Carvalho, M. A. A. Pinheiro deThe main goal of the present work was to determine the nutraceutical potential of Asparagopsis taxiformis D. extracts from Madeira Archipelago south coast. Extraction methodologies consisted either/or in 72 hours stirring, at room temperature (M1), or 6 cycles of Soxhlet extraction (M2), both with re-extraction. Solvents used were distilled water, ethanol, methanol and ethyl acetate. M1 allowed to obtain the hi...

Propagation of nine endemic plant species from Madeira Island (Portugal)
Henriques, Dina; Fontinha, Susana; Neves, Margarida Costa; Nóbrega, Humberto; Ferro, António; Carvalho, M. A. A. Pinheiro deEfficient propagation of endangered plant species is a critical factor in successful ecological restoration and conscientious habitat management. Hence, propagation trials of nine endemic plant species of Madeira (Anthyllis lemanniana Lowe, Armeria maderensis Lowe, Cedronella canariensis (L.) Webb & Berthel., Erica maderensis (Benth.) Bornm., Genista tenera (Jacq. ex Murray) Kuntze, Helichrysum melaleucum Rchb....
Biochemical composition, nutritional value, and antioxidant properties of seven...
Nunes, N.; Ferraz, S.; Valente, S.; Barreto, Maria Carmo; Carvalho, M. A. A. Pinheiro deBiochemical composition and antioxidant activity were assessed in seven seaweeds from Madeira Archipelago, namely, the chlorophyte (Ulva lactuca), the rhodophytes (Asparagopsis taxiformis, Chondrus crispus, Galaxaura rugosa, Grateloupia lanceola and Nemalion elminthoides), and the phaeophyte (Zonaria tournefortii). Seaweed mineral content varied from 16.60 to 84.16 g (100 g)-1 dry weight (dw). Organic matter, c...
Adapting clonally propagated crops to climatic changes: a global approach for t...
Lebot, V.; Tuia, V.; Ivancic, A.; Jackson, G. V. H.; Saborio, F.; Reyes, G.; Rodriguez, S.; Robin, G.; Traoré, R.; Aboagye, L.; Onyeka, J.Clonally propagated crop species are less adaptable to environmental changes than those propagating sexually. DNA studies have shown that in all countries where taro (Colocasia esculenta (L.) Schott) has been introduced clonally its genetic base is narrow. As genetic variation is the most important source of adaptive potential, it appears interesting to attempt to increase genetic and phenotypic diversity to st...
Genetic diversification and dispersal of taro (Colocasia esculenta (L.) Schott)
Chaïr, H.; Traore, R. E.; Duval, M. F.; Rivallan, R.; Mukherjee, A.; Aboagye, L. M.; Van Rensburg, W. J.; Andrianavalona, V.Taro (Colocasia esculenta (L.) Schott) is widely distributed in tropical and sub-tropical areas. However, its origin, diversification and dispersal remain unclear. While taro genetic diversity has been documented at the country and regional levels in Asia and the Pacific, few reports are available from Americas and Africa where it has been introduced through human migrations. We used eleven microsatellite marke...

Costa, G.; Moreira, E. Melo; Carvalho, M. A. A. Pinheiro deThe helminth parasite fauna of the oceanic horse mackerel Trachurus picturatus Bowdich 1825, caught off the Madeira Islands was composed of six different taxa. Prevalence and abundance of larval Anisakis sp. (Nematoda: Anisakidae) and Nybelinia lingualis (Trypanorhyncha: Tentaculariidae), the most common parasite taxa, were 24.3%, 0.9 and 37.9%, 0.7, respectively. Bolbosoma vasculosum (Acanthocephala: Polymorph...
