Semantides are of three types, viz., Primary semantide – DNA Secondary semantide- RNA Tertiary semantides – Proteins Sometimes the semantides together with the larger polysachharides, are …

The chemical substances which have been found very useful in taxonomy are secondary metabolites. Secondary metabolites (secondary plant products) perform non-vital (or at least non- universally vital) functions, and are less widespread in plants. The restricted occurrence of these metabolites among plants renders them valuable as taxonomic information. Secondary plant …

Plant Chemotaxonomy is one of the more fashionable and rapidly extending areas of plant taxonomy that seeks to utilize chemical information to improve classification of plants.It has many diverse and indeed ancient origins. 1. The foremost comes the search by Herbalists, and latterly by pharmacists, for drugs, which has involved …

DIVISION I PRINCIPLES PRINCIPLE I The nomenclature of algae, fungi, and plants is independent of zoological and prokaryotic nomenclature. This Code applies equally to names of taxonomic groups treated as algae, fungi, or plants, whether or not these groups were originally so treated. PRINCIPLE II The application of names of taxonomic …

The International Code of Nomenclature for algae, fungi, and plants (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those “traditionally treated as algae, fungi, or plants”. It was formerly called …
