  Reports regarding the chromosomal architecture of Brassica genomes and genome relationship among various species of the genus appeared in the second quarter of the 20th century AD. In the second quarter genome relationship was elaborated through secondary associations, pachytene and somatic karyotypes. Genome analysis and preferential pairing were extensively utilized for characterizing Brassica genomes in the third quarter. In last quarter of the century molecular characterization supplemented the conventional analytical tools for understanding the infrastructure of Brassica genomes. Whether it is the breeding system analysis, chromosome morphology, meiotic associations or molecular characterization proves that Brassica is monophyletic origin and it descended from an unknown six chromosomal prototype. Scientific developments made in Brassica genetics, from genome analysis to genomics during the 20th century AD are generalized in this paper.

  Besides preserving mines of salts, minerals, fossils, archeological and cultural heritage; the mountainous terrain of the Salt Range also has immense potential for its biodiversity in the broadly overlapping “the subtropical dry evergreen and the thorny subtropical semi deciduous” types of forest ecologies. Olea ferruginea, Acacia modesta, Reptonia buxifolia and Salvadora oleoides represent the apparent arboreal landscape of the terrain. More than 92 medicinal plants are not only used for curing ailments ranging from mild infections to the chronic ulcers but are also contributing a lot to the rural economy of the area. Floral diversity in general, the species of Litsea, Neolitsea and Colchicum in particular, are exposed to severe collection and the habitat loss pressures. Commonly known medicinal plants of the Salt Range, Punjab and their therapeutic uses are presented in this paper.

  A study was conducted on male pseudohermaphrodites who got transformed from females to males during the years 1983-85, at the age of eighteen and thirty-two. The younger sister (18 years old) transformed before marriage, whereas, the elder sister (32 years old) remained a housewife for about 20 years. No one else in the family was recorded with similar genital anomaly except one ambiguous female. The clinical reports, morpho-anatomical features and chromosomal pattern reveal their testicular feminization/male pseudohermaphroditism.

  Monoterpene glycosides have been isolated from the ethyl acetate soluble fraction of Indigofera hetrantha and their structures assigned to be 3,7-dimethyl-2(E),6-octadien-5-one-1-O-β-D-6-O-acetylglucopyranoside (1) and 3,7-dimethyl-2(E), 6-octadien-5-one-1-O-[-β-D-6’’-O-acetylglucopyra-nosyl (1’’ → 6’)-β-D-glucopyranoside] (2), on the basis of spectroscopic analysis including 1D and 2D NMR techniques. Compounds 1 and 2 displayed moderate inhibitory potential against the enzyme lipoxygenase.

  This study communicates the result of 24 promising tea genotypes evaluated through 11 Randomly Amplified Polymorphic DNA primers. High level of genetic diversity was observed on DNA level among the genotypes. The results of cluster analysis based on RAPDs revealed that four major groups could be recognized in tea grown in Mansehra District.

  Shawer Valley, District Swat was ethno-medicinally collated during summer, 2003. The study revealed that 88 species of 82 genera belonging to 58 families are traditionally used as medicinal plants. Thirty-two of these plants were medicinally used for the curing of Stomach or Gastric problems. Renal disorders are locally treated with 10 species. Jaundice and its associated fevers are healed with 7 species. For cough and cold 6 species are in practice. Skin diseases and wound healing are treated each with 4 species independently. Some of the plants are used as expectorant, anti diabetic and as general body tonic. Habitat fragmentation and unwise use of these plants are threatening them with extinction. Elaboration of conservation status for checking irreversible losses to the genetic resources of MAP’s and introduction of wise-use practices are imperative for effective conservation of the resources.
