    Abstract Halophytes are an excellent choice for the study of genes conferring salt tolerance to salt-sensitive plants and, they are suitable for reclamation and remediation of saline soil. We develop an in vitro plant propagation protocol and studies of genes involved with GB and Pro biosynthesis in Suaeda edulis. Axillary buds were used as explants and cultured in different treatments on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of plant growth regulators. The highest number of multiple shoots was on MS medium containing 1 mg/L Benzyladenine (BA) and / or 2 g/L activated… More >

    Leaf and stem anatomy of three halophytic Salicornieae (Chenopodiaceae) from Argentina

    Pérez Cuadra V y PM Hermann

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 369-377, 2014, DOI:10.32604/phyton.2014.83.369

    Abstract Species belonging to the tribe Salicornieae (Chenopodiaceae), called jumes, are rich in salts, reflecting its halophytic nature. The leaf and stem anatomy of Allenfolfea patagonica, Heterostachys olivascens and H. ritteriana were studied. The material, collected in the Salitral de la Vidriera located 30 km from Bahia Blanca (Buenos Aires, Argentina), was fixed, dehydrated, embedded and stained with traditional techniques for plant anatomy. The foliar abaxial epidermis of the three species had papillate cells, while the adaxial one, usually did not. The stomata were sunken in the abaxial epidermis of the three species, and of the adaxial one… More >

    Comparative vegetative anatomy between halophytic Chloridoideae (Poaceae) with forage importance

    Pérez Cuadra V y V Cambi

    Phyton-International Journal of Experimental Botany, Vol.79, pp. 69-76, 2010, DOI:10.32604/phyton.2010.79.069

    Abstract Pappophorum phillippianum and Trichloris crinita grow in areas where traditional forages cannot establish. They are not food resources for excellence, but have some nutritional value to domestic livestock. Leaves and stems collected in a natural halophytic field were treated using current techniques for describing their epidermic and anatomical characteristics. Blades of both species have papillose adaxial epidermis, and it is also the case for the abaxial epidermis in T. crinita. Silica bodies are double-axe shaped or cross shaped. Both species show foliar glandular and eglandular trichomes. Only T. crinita shows prickles. Anatomically, both species show groups of fibers in… More >

    Photosynthetic Behaviour and Mineral Nutrition of Tamarix gallica Cultivated Under Aluminum and NaCl Combined Stress

    Dhouha Belhaj Sghaier1, Insaf Bankaji1, Sylvia Pedro2, Isabel Caçador2, Noomene Sleimi1,*

    Phyton-International Journal of Experimental Botany, Vol.88, No.3, pp. 239-252, 2019, DOI:10.32604/phyton.2019.06887

    Abstract The lack of knowledge of plant tolerance and differential response to aluminum (Al) encouraged many researchers, in the last decade, to elucidate Al toxicity and tolerance mechanisms. The current study reported the impact of Al, a toxic element with negative effects on plant growth and development, in halophytic plant Tamarix gallica. Plants were subjected to different Al concentrations (0, 200, 500 and 800 μM) with or without NaCl (200 mM) supplementation. Growth, photosynthesis and mineral content were assessed. Al stress had a significant decrease on shoots’ biomass production between 19 to 41%, and a little variation… More >
