Mycoplasma Like Organisms or Pleuro Pneumonia Like Organisms (PPLO)
Abstract: Mycoplasma like Organisms is the smallest of microorganisms causing plant disease. Viruses are acutely small (they can be seen only with the aid of an electron microscope), being composed of nothing more than a protein shell consisting a small amount of genetic material. Plant viruses commonly survive year-round in perennial weeds and trees or insect vectors, and are transmitted to other plants via feeding activities of certain insects, usually aphids, …

Methods of Crop Breeding in Plants: A Review
Abstract: In mass selection, seeds are gathered from (as a rule a couple of dozen to a couple of hundred) desirable appearing individuals in a populace, and the cutting edge is sown from the supply of blended seed. This technique, some of the time alluded to as phenotypic selection, depends on how every individual looks. Mass selection has been used widely to improve old “land” varieties that have been passed down …

Bacterial Diversity of Decomposing Leaf Litters of Polyalthia longifolia (Sonner.) Thw. and Rhododendron arboreum Sm. Under Natural Condition
Abstract: The role of microorganisms in the decomposition of plant material is of immense importance. A large amount of plant litter is added annually to the soil through leaf fall and death of plants. As the plant materials fall on the ground, they are immediately attacked by various groups of soil microorganisms and soon after, the process of decomposition is initiated. Microorganisms being heterotrophic in their mode of nutrition are responsible …

Nitric Oxide & Inducible Nitric Oxide Synthase: A Glimpse on Biological Role
Abstract: Nitric oxide (NO) is a multifunctional molecule having numerous physiological and pathophysiological functions. It is synthesized from L-arginine by three different isoforms of nitric oxide synthase (NOS), which are categorized into two subtypes; constitutive nitric oxide synthase (cNOS) and inducible nitric oxide synthase (iNOS). Constitutive nitric oxide synthase (cNOS) is constitutively expressed in the cells, while inducible nitric oxide synthase (iNOS) is expressed within several hours after the stimulation of …
