Regulatory small RNAs which range in size from 20 to 24 nucleotides are ubiquitous components of endogenous plant transcriptomes as well as common responses to exogenous viral infections and introduced double stranded RNA dsRNA Endogenous small RNAs derive from the processing of helical RNA precursors and can be categorized
·The various taxa or ranks used in plant classification following ICBN in ascending hierarchy are Species Genus Family Order Class Subdivision Division and Kingdom The naming of plants and understanding of the species relationship to other species is essential for botanists pharmacognosists phytochemists and other
Polysaccharides are the most abundant naturally occurring macromolecular polymers which are obtained from renewable sources such as algae plants and microorganisms such as fungi and bacteria Fig 1 [] Together with other biomolecules like proteins and nucleotides polysaccharides are an essential component and exert many activities in the biological
· i On the basis of a place where a plant grows its habitat plants are classified into three groups Mesophytes Plants which grow on land and need moderate amount of water Examples Potato tomato Hydrophytes Plants that need maximum water to grow and hence live in water They may be floating or partially/completely submerged
