Carrying out of indoor radon studies have been done in the 50 dwellings of Bathinda district (Punjab), India using LR-115 type II cellulose nitrate films in the bare mode. The films were exposed into four consecutive trimesters, i.e. from March 2010

Allopolyploids are organisms possessing more than two complete sets of chromosomes from two or more species and are frequently more vigorous than their progenitors. To address the question why allopolyploids display hybrid vigor, we compared the natu

We examined nine Y chromosome short tandem repeats (Y-STRs) and the mitochondrial DNA (mtDNA) hypervariable segment 1 region in the Fijian island populations of Viti Levu, Vanua Levu, Kadavu, the Lau islands and Rotuma. We found significant genetic s

Polyploidization is an important mechanism for introducing diversity into a population and promoting evolutionary change. It is believed that most, if not all, angiosperms have undergone whole genome duplication events in their evolutionary history,

Embryogenic callus was initiated by culturing in vitro taro corm slices on agar-solidified half-strength MS medium containing 2.0 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) for 20 days followed by transfer to 1.0 mg/L thidiazuron (TDZ). Callus was s

Callus was initiated in three different “esculenta” taro cultivars by culturing corm slices in the dark on half-strength MS medium supplemented with 2.0 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) for 20 days followed by subculture of all corm sl

Changes in chromosome number have a critical role in the evolution and formation of plant species. Triploids, which carry three complete sets of chromosomes, in particular produce offspring with different chromosome numbers, including diploid and tet

The application of the droplet vitrification cryopreservation technique to taro accessions from a range of Asia Pacific countries is presented. The optimum protocol involves excision of about 0.8 mm shoot-tips from in vitro plants, 20–40 min PVS2 e

Polyploids are common and arise frequently by genome duplication (autopolyploids) or interspecific hybridization (allopolyploids). Neoallopolyploids display sterility, lethality, phenotypic instability, gene silencing and epigenetic changes. Little i

Although allopolyploids are common in nature and in agriculture, knowledge of their origin, evolution and genomic regulation is limited. We study synthetic allotetraploids of Arabidopsis thaliana and Arabidopsis arenosa as well as the natural allotet
