A perfusive method combined with an open-system carbon dioxide measurement system was used to assess rhizosphere respiration of Acer saccharum Marsh. (sugar maple) and Betula alleghaniensis Britton (yellow birch) seedlings grown in 8-l pots filled with coarse sand. We compared in vivo and in situ rhizosphere respiration between species, among light regimes (40, 17 and 6% of full daylight) and a...

Multiple polyploidizations with divergent consequences in the grass subtribe Saccharinae provide a singular opportunity to study in situ adaptation of a genome to the duplicated state, heretofore known primarily from paleogenomics. We show that allopolyploidy in a common Miscanthus-Saccharum ancestor ∼3.8 to 4.6 million years ago closely coincides in time with their divergence from the Sorghum ...

Sugarcane is the main source of the world's sugar and is becoming increasingly important as a source of biofuel. The highly polyploid and heterozygous nature of the sugarcane genome has meant that characterization of the genome has lagged behind that of other important crops. Here we developed a method using a combination of quantitative PCR with a transposable marker system to score the relati...

Expressed sequence tags (ESTs) in the sugarcane (Saccharum spp) database (SUCEST) were electronically searched and 402 microsatellites identified. Various dinucleotide and trinucleotide simple sequence repeat (SSR) motifs were found, with these being more frequently observed in ESTs obtained from flower cDNA libraries. PCR primers were designed for 20 of these SSRs and were tested on eight suga...

Sugarcane is a major crop used for food and bioenergy production. Modern cultivars are hybrids derived from crosses between Saccharum officinarum and Saccharum spontaneum. Hybrid cultivars combine favorable characteristics from ancestral species and contain a genome that is highly polyploid and aneuploid, containing 100-130 chromosomes. These complex genomes represent a huge challenge for molec...

Saccharum spontaneum L. is a crucial wild parent of modern sugarcane cultivars whose ploidy clones have been utilized successfully in improving the stress resistance and yield related traits of sugarcane cultivars. To establish knowledge regarding the genetic variances and evolutional relationships of ploidy clones of Saccharum spontaneum collected in China, the rDNA-ITS sequences of 62 ploidy ...

Target region amplification polymorphism (TRAP) is a fairly new PCR-based molecular marker technique which uses gene-based information for primer design. The objective of this study was to evaluate the utility of TRAP markers for assessing genetic diversity and interrelationships in sugarcane germplasm collections. Thirty genotypes from the genera Saccharum, Miscanthus, and Erianthus were used ...
