Nudibranchs that exclusively eat scleractinian corals provide a rare opportunity to study specialist predation in the marine environment. To measure the diet breadth of 4 Phestilla species on Guam, we offered the nudibranchs different corals in choice and no-choice feeding assays. Larval preferences were determined by measuring the percent metamorphosis in response to different coral species. W...

Spices and herbs have been used for many years by different cultures. The aim of the present study is (1) to investigate in-vitro antimicrobial effects of different spices and herbs (5 species: Rosmarinus officinalis (Rosemary), Coriandrum sativum (coriander), Micromeria fruticosa (L.) Druce subsp. Brachycalyx P.H. Davis (White micromeria), Cumium cyminum (cumin), Mentha piperita (Peppermint) a...

In vertebrates, COX-1 and COX-2, two cyclooxygenase isozymes with different physiological functions and gene regulation, catalyze identical reactions in prostaglandin synthesis. It is still not understood why there are multiple forms of COX enzyme in the same cell type and when the evolutionary duplication of the COX gene occurred. Here we report the structure of two genes encoding for COX isoz...

Sages are medicinal and aromatic plants that constitute a large pool from which active compounds of great pharmaceutical potential can be derived, while at the same time, they also have ornamental value. The purpose this study was to develop micropropagation protocols Salvia fruticosa, S. officinalis, ringens, tomentosa, pomifera ssp. facilitate their exploitation in floriculture industries. In...

Anatomical characteristics play a pivotal role in understanding the evolutionary relationship among various plant taxa and identifying species of pharmacological importance. Though anatomical features family Apocynaceae have been widely recognized, there is limited research on stem wood anatomy Kopsia fruticosa, whereas nothing was previously known about its root anatomy. The present work descr...

Caryological studies were carried out on ten species of the genus Suaeda belonging to 27 samples of different populations in Iran. Important chromosome features including numbers, lengths, centromere locations and caryotypes were studied. All the species have basic chromosome numbers of x=9. Chromosome counts of S. acuminata (C.A.Mey.) Moq. (2n=18), S. aegyptiaca (Hasselq.) Zoh., (2n=l8)...
