background and objectives: chlorophyceae are important constituents of marine phytoplankton. the taxonomy of chlorophyceae was traditionally based solely on morphological characteristics. in the present research project, genetic diversity was investigated to analyze five species of chlorophyceae from waters of the persian gulf. materials and methods:   a clone library of the ribosomal small sub...

the formation and regulation of vertebrate endogenous intestinal microbiota has been widely studied as the microbiota plays a crucial role in the host nutrition, development, and health. despite the importance of microbiota for host health, it is still unclear whether the endogenous intestinal microorganisms are genetically distinct or whether they are genetically related with each other in dif...

The intestinal bacterial diversity of Stichopus japonicus was investigated using 16S ribosomal RNA gene (rDNA) clone library and Polymerase Chain Reaction/Denaturing Gradient Gel Electrophoresis (PCR-DGGE). The clone library yielded a total of 188 clones, and these were sequenced and classified into 106 operational taxonomic units (OTUs) with sequence similarity ranging from 88 to 100%. The cov...

Coffee cultivation in Indonesia generally only relies on rainfall as a source of water. Drought that occurs the dry season inhibits growth, reduces yields, and even death plants. Not all plants are equally resistant to drought conditions. Drought-resistant coffee clones usually develop several resistance mechanisms, including formation specific compounds protect cells tissues from damage caused...

The depletion of log resources encourages research into alternative ways to sustain the wood supply. Therefore, 4-year-old Rubber Research Institute Malaysia (RRIM) clones series, RRIM 2020 and 2025, were chosen as potential raw materials for particleboard in this study. purpose study was assess effects planting density rubber tree on mechanical physical properties single-layer particleboard. d...
