Abstract Phenolics are vital for the adaptation of plants to terrestrial habitats and species diversity. Phenoloxidases (catechol oxidases, COs, laccases, LACs) responsible oxidation polymerization phenolics. However, their origin, evolution, differential roles during plant development land colonization unclear. We performed phylogeny, domain, amino acids, compositional biases, intron analyses ...
Plankton composition and physicochemical properties of Ajiwa water reservoir were assessed over a twelve (12) month period. The biological parameters determined using conventional methods procedures at three sampling points. outcome was revealed. phytoplankton Chlorophyta (57.66%), Bacillariophyta (25.70%), Cyanophyta (14.73%), Dinophyta (1.91%), with Rotifera (30.55%), Copepoda (29.33%), Proto...
BACKGROUND AND AIMS Consensus higher-level molecular phylogenies present a compelling case that an ancient divergence separates eukaryotic green algae into two major monophyletic lineages, Chlorophyta and Streptophyta, and a residuum of green algae, which have been referred to prasinophytes or micromonadophytes. Nuclear DNA content estimates have been published for less than 1% of the described...
مطالعه مستمر اکولوژیک دریای خزر، بخصوص پراکنش و شناسایی ترکیب گونهای ، تراکم و زیتوده، نوسانات فصلی و منطقهای فیتوپلانکتون ها قبل از هر مطالعه ای ضروری بنظر میرسد. با توجه به شرایط متنوع فیزیکوشیمی آبهای رودخانه های منتهی به دریا، وضعیت مختلف توپوگرافی بستر دریا بنظر می رسد که تولید اولیه در مناطق مختلف دریای خزر در فصول مختلف، متفاوت می باشد. این تحقیق طی سال 1389 در فصول بهار، تاب...
Many reports have revealed that the abundance of microalgae in shrimp ponds vary with changes in environmental factors such as light, temperature, pH, salinity and nutrient level throughout a shrimp culture period. In this study, shrimp cultivation period was divided into three stages (initial = week 0-5, mid = week 6-10 and final = week 11-15). Physical and chemical parameters throughout the c...
