This is the oldest English language journal in genetics. Founded by W. Bateson and R. C. Punnett in 1910, the Journal of Genetics was later edited by J. B. S. Haldane; later, Haldane and his wife, Helen Spurway brought the journal with them to India. After his death in 1964, Mrs. Haldane continued publication of the journal, with Madhav Gadgil and H. Sharat Chandra (Indian Institute of Science, Bangalore) and Suresh Jayakar (Laboratorio de Genetica Biochimica ed Evoluzionistica, Pavia) as editors, until her own death in 1977. In 1985, with the permission of Haldane’s heirs, the Indian Academy of Sciences resumed publication of the journal. The journal retains its traditional interest in evolutionary research that is of relevance to geneticists, even if not explicitly genetic in nature.

Natural products with medicinal value are gradually gaining importance in clinical research due to their well-known property of no side effects as compared to drugs. Tinospora cordifolia commonly named as "Guduchi" is known for its immense application in the treatment of various diseases in the traditional ayurvedic literature. Recently the discovery of active components from the plant and their biological function in disease control has led to active interest in the plant across the globe. Our present study in this review encompasses (i) the genetic diversity of the plant and (ii) active components isolated from the plant and their biological role in disease targeting. The future scope of the review remains in exploiting the biochemical and signaling pathways affected by the compounds isolated from Tinospora so as to enable new and effective formulation in disease eradication.

Lentil (Lens culinaris ssp. culinaris), is a self-pollinating diploid (2n = 2x = 14), cool-season legume crop and is consumed worldwide as a rich source of protein (∼24.0%), largely in vegetarian diets. Here we report development of a genetic linkage map of Lens using 114 F2 plants derived from the intersubspecific cross between L 830 and ILWL 77. RAPD (random amplified polymorphic DNA) primers revealed more polymorphism than ISSR (intersimple sequence repeat) and SSR (simple sequence repeat) markers. The highest proportion (30.72%) of segregation distortion was observed in RAPD markers. Of the 235 markers (34 SSR, 9 ISSR and 192 RAPD) used in the mapping study, 199 (28 SSRs, 9 ISSRs and 162 RAPDs) were mapped into 11 linkage groups (LGs), varying between 17.3 and 433.8 cM and covering 3843.4 cM, with an average marker spacing of 19.3 cM. Linkage analysis revealed nine major groups with 15 or more markers each and two small LGs with two markers each, and 36 unlinked markers. The study reported assigning of 11 new SSRs on the linkage map. Of the 66 markers with aberrant segregation, 14 were unlinked and the remaining 52 were mapped. ISSR and RAPD markers were found to be useful in map construction and saturation. The current map represents maximum coverage of lentil genome and could be used for identification of QTL regions linked to agronomic traits, and for marker-assisted selection in lentil.

Ethnobotany gives an understanding of interrelationships between people and plants. It deals with the documentation of the indigenous traditional knowledge of plants possessed by ethnic people and primitive communities who also are the custodians of this knowledge. They practice the traditional way of treatment for various ailments. Now, this knowledge holds both cultural as well as scientific value. The ethnobotanical knowledge also provides the source for the discovery of many drugs. Usage of Himalayan plant species for food and medicine has been well known for a long time. This knowledge is depleting rapidly in recent times due to globalization and modernization. This investigation provides ethnobotanical information from selected studies that truly focuses on the traditional medicinal plants used by the local people of the Kangra district. Information for the present study was collected through publications available on the ethnobotanical studies of the area. These studies provide relevant literature and inventories of useful plants. As the search for natural products and new drugs from plants is an important element, it becomes important to create awareness about biodiversity conservation as well as their role in healthcare. Measures are needed to support biodiversity prospecting and for conserving useful plants which are harvested only from the wild. Paying special attention to sustainable use of the ethnomedicinal plants found in the area may help lessen the impact of harvesting specific plant resources.
