Ptychostomum rubens; Thamnium alopecurum decipiens Scorpiurium circinatum; and Trichostomum mediterraneum algeriae Müll. Hal. ex Geh. Hydrogonium bolleanum. Funaria altiss...

A new species, Cryptomonas tropica sp. nov., is described from Cat Tien National Park (Vietnam) based on morphological and molecular data. Strains of the species were isolated soil, which an unusual environment for photosynthetic cryptomonads. This has elliptical cells in ventral view a single plastid notched into several irregular lobes without microscopically visible pyrenoids. Phylogenetic r...

The impact of water stress on antioxidant enzyme activities, proline, soluble sugars, and carotenoids contents found in Digitaria commutata Cenchrus ciliaris plants was investigated. Two different watering regimes were used over a period three months. Water decreased total chlorophyll content plants, but increased content. Interestingly, no change observed the quantum yield PSII photochemistry ...
