13. Germination Ecology of Lathyrus aphaca, a Problematic Weed of Wheat Crop under Semi-Arid Conditions of Pakistan
RESUMO: Lathyrus aphaca é uma planta daninha dicotiledônea agressiva. O efeito de diferentes componentes e fatores agroecológicos na ecologia da germinação dessa planta daninha foi investigado sob condições de estufa e laboratório em 2014. Foi observada menor resposta germinativa de L. aphaca em condições de alta temperatura, ao passo que a germina

14. Ecophysiology of Germination of Parkia platycephala Benth. Seeds
ABSTRACT Water is considered the most important environmental resource for the germination process. This study aimed to evaluate the germination performance of Parkia platycephala seeds under different conditions of water and saline stress. Seed germination was tested with solutions of poly (ethylene glycol) 6000 and sodium chloride (NaCl) at seven osmotic

15. Identification of a pore-forming protein from sea anemone Anthopleura dowii Verrill (1869) venom by mass spectrometry
Abstract Background: Pore-forming proteins (PFP) are a class of toxins abundant in the venom of sea anemones. Owing to their ability to recognize and permeabilize cell membranes, pore-forming proteins have medical potential in cancer therapy or as biosensors. In the present study, we showed the partial purification and sequencing of a pore-forming protein f

16. Elastic and Osmotic Adjustment of Talipariti elatum (Sw) Frixell Grown in Organic Substrates
ABSTRACT The aim of the present study was to evaluate the water response of Talipariti elatum cultivated in different substrates. Sugarcane straw, peat, biochar and mixtures of sugarcane straw and biochar, and peat and biochar were used. The physical properties of each substrate and the water parameters of the species were determined based on the pressure-v

17. Hemolytic, anticancer and antigiardial activity of Palythoa caribaeorum venom
Abstract Background Cnidarian venoms and extracts have shown a broad variety of biological activities including cytotoxic, antibacterial and antitumoral effects. Most of these studied extracts were obtained from sea anemones or jellyfish. The present study aimed to determine the toxic activity and assess the antitumor and antiparasitic potential of Palythoa

18. Drying and reduction in sensitivity to desiccation of seeds of Alibertia edulis: the influence of fruit ripening stage
ABSTRACT The intense environmental degradation in tropical regions suitable for agriculture has decreased native forest populations of plants with important fruits and medicinal properties. Alibertia edulis is a native tree from the Brazilian Cerrado. Knowledge about the effects of drying and storage on the physiological behavior of its seeds may aid in its

19. Physiological response of Cucurbita pepo var. pepo mycorrhized by Sonoran desert native arbuscular fungi to drought and salinity stresses
ABSTRACT Plants response to symbiosis with arbuscular mycorrhizal fungi (AMF) under water stress is important to agriculture. Under abiotic stress conditions native fungi are more effective than exotics in improving plant growth and water status. Mycorrhization efficiency is related to soil fungi development and energy cost-benefit ratio. In this study, we a

20. Decades of research in drug targeting using gastroretentive drug delivery systems for antihypertensive therapy
ABSTRACT The limitations in absorption of drugs with narrow absorption window, or those unstable in the intestinal pH or those exhibiting low solubility at high pH are primary candidates for gastroretentive drug delivery systems (GRDDS). The delivery system has been widely explored for its commercial potential for a wide variety of therapeutic agents. GRDDS

21. Effect of some environmental factors on seed germination of Eryngium caeruleum M. Bieb. populations
ABSTRACT The effects of alternating and constant temperatures and light regimes, osmotic and salt stress and pH were tested on seed germination in four populations of Eryngium caeruleum. Laboratory experiments revealed that the four populations exhibited different responses to alternating temperature and light conditions. Alternating temperature and photoper

22. Effects of Arbuscular Mycorrhiza on Osmotic Adjustment and Photosynthetic Physiology of Maize Seedlings in Black Soils Region of Northeast China
ABSTRACT To investigate the effect of arbuscular mycorrhiza fungi on maize growth, osmoregulation substances and photosynthetic physiology, a popular maize variety ZD 958 was measured under potted condition. Arbuscular mycorrhiza (AM) symbiosis promoted plant growth, and enhanced plant height, leaf length, mean leaf width and dry weight. Higher soluble sugar

24. Proteomic analysis of halotolerant proteins under high and low salt stress in Dunaliella salina using two-dimensional differential in-gel electrophoresis
Abstract Dunaliella salina, a single-celled marine alga with extreme salt tolerance, is an important model organism for studying fundamental extremophile survival mechanisms and their potential practical applications. In this study, two-dimensional differential in-gel electrophoresis (2D-DIGE) was used to investigate the expression of halotolerant proteins u
