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 (Ba...
متن کاملDiversity of the Bacterial Microbiome in the Roots of Four Saccharum Species: S. spontaneum, S. robustum, S. barberi, and S. officinarum
Endophytic bacteria are nearly ubiquitously present in the internal tissues of plants, and some endophytes can promote plant growth. In this study, we sampled the roots of four ancestral species of sugarcane (two genotypes per species) and two sugarcane cultivars, and used 16S rRNA and nifH gene sequencing to characterize the root endophytic bacterial communities and diazotroph diversity. A tot...

15 صفحه اولDetailed alignment of saccharum and sorghum chromosomes: comparative organization of closely related diploid and polyploid genomes.
The complex polyploid genomes of three Saccharum species have been aligned with the compact diploid genome of Sorghum (2n = 2x = 20). A set of 428 DNA probes from different Poaceae (grasses) detected 2460 loci in F1 progeny of the crosses Saccharum officinarum Green German x S. spontaneum IND 81-146, and S. spontaneum PIN 84-1 x S. officinarum Muntok Java. Thirty-one DNA probes detected 226 loc...
متن کاملLine x tester analysis in sugarcane (Saccharum officinarum)
Combining ability variances and effects were estimated for important agronomic and biochemical traits in sugarcane using line x tester mating design. Five commercially grown varieties and one line from germplasm collection were involved in this study of which three were used as females (lines) and three as males (testers). The six agronomic characters studied were number of millable stalk per s...
