Molecular markers are used for germplasm characterization, genetic mapping, gene tagging, and gene introgression from exotic species in brassica. Genetic maps aids to the understanding of genome in terms of structure, function and evolution and represents an important tool for crop enhancements on genetic level. Present study aims at reviewing the use of molecular markers for mapping and tagging qualitative and quantitative traits in brassica so that this information can be easily available to researchers as a reference. A number of important traits in light of molecular genetics in Brassica are described in detail.

In corpus linguistics, part-of-speech tagging (POS tagging or POST), also called grammatical tagging or word-category disambiguation, is the process of marking up the words in a text (corpus) as corresponding to a particular part of speech, based on both its definition, as well as its context —ie. relationship with adjacent and related words in a phrase, sentence, or paragraph. A simplified form of this is commonly taught to school-age children, in the identification of words as nouns, verbs,adjectives, adverbs, etc. Once performed by hand, POS tagging is now done in the context of computational linguistics, using algorithms which associate discrete terms, as well as hidden parts of speech, in accordance with a set of descriptive tags.

Molecular design software is software deals with molecular modeling, that provides special support for developing molecular models de novo. In contrast to the usual molecular modeling programs such as the molecular dynamics and quantum chemistry programs, such software directly supports the aspects related to the construction of molecular models: Molecular graphics interactive molecular drawing and conformational editing building of polymeric molecules, crystals and solvated systems partial charges development geometry optimization support for the different aspects of Force Field development
Septoria leaf spot caused by Septoria lycopersici Speg. and late blight caused by Phytopthora infestans (Mont.) de Bary are two important foliar diseases of tomato (Solanum lycopersicum L.). Identification of DNA markers linked to these diseases is a prerequisite for accelerating resistance breeding through marker-assisted selection (MAS). The objectives of the present study were to investigate the inheritance pattern of septoria leaf spot resistance and identify molecular markers linked to septoria leaf spot and late blight resistance in tomato. The inheritance of resistance to septoria leaf spot was based on a single dominant gene. Transgressive segregation for resistance and susceptibility to late blight was also observed. Out of the 34 RAPD polymorphic markers 11 primers (32.35%) were polymorphic between resistant and susceptible bulks of septoria leaf spot and 16 (47%) produced polymorphic bands between resistant and susceptible bulks of late blight lines.
A comprehensive look at empirical approaches to molecular discovery, their relationships with rational design, and the future of both Empirical methods of discovery, along with serendipitous and rational design approaches, have played an important role in human history. Searching for Molecular Solutions compares empirical discovery strategies for biologically useful molecules with serendipitous discovery and rational design, while also considering the strengths and limitations of empirical pathways to molecular discovery. Logically arranged, this text examines the different modes of molecular discovery, empha-sizing the historical and ongoing importance of empirical strategies. Along with a broad overview of the subject matter, Searching for Molecular Solutions explores: The differing modes of molecular discovery Biological precedents for evolutionary approaches Directed evolutionary methods and related areas Enzyme evolution and design Functional nucleic acid discovery Antibodies and other recognition molecules General aspects of molecular recognition Small molecule discovery approaches Rational molecular design The interplay between empirical and rational strategies and their ongoing roles in the future of molecular discovery Searching for Molecular Solutions covers several major areas of modern research, development, and practical applications of molecular sciences. This text offers empirical-rational principles of broad relevance to scientists, professionals, and students interested in general aspectsof molecular discovery, as well as the thought processes behind experimental approaches.

Due to lack of suitable selection criteria, the development of highly salt tolerant high yielding varieties in rice remain as an incomplete episode & in this cross road the molecular markers finds appropriate place to be used upon. These are more potential; having better resolution and not gets affected by the changing environment. In the present study efforts were made to tag salt tolerant gene(s) in a F3 mapping of Pokkali X IR 28 with concurrent phenotyping in response to excess salt under artificial condition. The result shows ample polymorphism in respect of 10 decamer primers, which is essential for a molecular marker programme in mapping gene of interest. From this study, it can be concluded that RAPD may be used in tagging gene(s) for salt tolerance in rice with no hesitation. The present information suffice amply that RAPD could be used as a reliable, easy to handle and cheap marker system in molecular profiling of F3 segregants.
