comparative structural analysis of bru1 region homeologs in saccharum spontaneum and s. officinarum.	sugarcane is a major sugar and biofuel crop, but genomic research and molecular breeding have lagged behind other major crops due to the complexity of auto-allopolyploid genomes. sugarcane cultivars are frequently aneuploid with chromosome number ranging from 100 to 130, consisting of 70-80 % s. officinarum, 10-20 % s. spontaneum, and 10 % recombinants between these two species. analysis of a genomic region in the progenitor autoploid genomes of sugarcane hybrid cultivars will reveal the nature ...	2016	27287040

feeding preferences of the asian elephant (elephas maximus) in nepal.	nepal provides habitat for approximately 100-125 wild asian elephants (elephas maximus). although a small proportion of the world population of this species, this group is important for maintaining the genetic diversity of elephants and conservation of biodiversity in this region. knowledge of foraging patterns of these animals, which is important for understanding their habitat requirements and for assessing their habitat condition, is lacking for the main areas populated by elephants in nepal. ...	2016	27855704
analysis of three sugarcane homo/homeologous regions suggests independent polyploidization events of saccharum officinarum and saccharum spontaneum.	whole genome duplication has played an important role in plant evolution and diversification. sugarcane is an important crop with a complex hybrid polyploid genome, for which the process of adaptation to polyploidy is still poorly understood. in order to improve our knowledge about sugarcane genome evolution and the homo/homeologous gene expression balance, we sequenced and analyzed 27 bacs (bacterial artificial chromosome) of sugarcane r570 cultivar, containing the putative single-copy genes lf ...	2017	28082603
isolation and characterization of centromeric repetitive dna sequences in saccharum spontaneum.	sugarcane (saccharum hybrids spp.) is the most important sugar crop that accounts for ~75% of the world's sugar production. recently, a whole-genome sequencing project was launched on the wild species s. spontaneum. to obtain information on the dna composition of the repeat-enriched region of the centromere, we conducted a genome-wide analysis of the dna sequences associated with cenh3 (a mutant of histone h3 located in eukaryote centromeres) using chromatin immunoprecipitation followed by seque ...	2017	28134354
