The aim of this study was to investigate the effective concentration of ethanolic extract  of bee pollen on liver, spleen and heart tissues of fish. Bee pollen extract in various concentrations (0.5, 2.5, 5, 10, 20 and 30 ppm) was administered to fish for 96 h under aquarium conditions. The malondialdehyde (MDA) levels, total antioxidant status (TAS), total oxidant status (TOS), oxidative stres...

Germinated pollen grains form pollen tubes that accomplish rapid polarized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more comprehensive understanding of proteins involved in pollen development, germi...
