Reproductive Structures of Pteridophyte

  Reproductive Structures of Pteridophyte The Pteridophyte sporophyte, besides being a prominent component of soil and vegetation, is an important ornamental plant in gardens and lawns. Indoors, its gracefulness and shape fit it ideally as a plant for pot culture in hallways and living rooms, especially during the months of November to March. Transportation of whole plants from one place to another without damage is attempted by packing them in sand, decomposed silt, ashes, or sawdust. Despite their rich horticultural value, many Pteridophytes are vanishing from nature due to indiscriminate destruction of their natural habitats and capturing of species for ornamental purposes. The best means of conservation is an adequate botanical knowledge of these plants, together with their habitats. The approaches of the non-destructive collection of herbarium specimens are now being stressed. The collection is also supplemented with data regarding the locality and habitat, so as to make it de...

CHROMODOMAIN AND BROMODOMAIN

  Chromodomain A chromodomain is a protein structural domain of around 40-50 amino acid residues that is frequently found in proteins involved in chromatin remodelling and manipulation. Additionally, it is referred to as a chromatin organisation modifier. It was discovered for the first time in Drosophila moderators of variegation.The chromodomains remodel chromatin into the condensed shape of heterochromatin, a cytologically observable state of suppressed gene expression.Both plants and animals have a high degree of conservation within the domain.It is encoded by a huge number of proteins found in a wide variety of genomes.Certain genes with chromodomains have several alternative splicing isoforms that lack the chromodomain altogether.Chromodomain-containing proteins are involved in many aspects of gene regulation in mammals, including chromatin remodelling and the development of heterochromatin areas. Additionally, proteins with chromodomains bind methylated histones and are incl...
