Harnessing stem carbohydrate dynamics in grasses offers an opportunity to help meet future demands for plant-based food, fiber and fuel production, but requires a greater understanding of the genetic controls that govern the synthesis, interconversion and transport of such energy reserves. We map out a blueprint of the genetic architecture of rice (Oryza sativa) stem nonstructural carbohydrates (NSC) at two critical developmental time-points using a subpopulation-specific genome-wide association approach on two diverse germplasm panels followed by quantitative trait loci (QTL) mapping in a biparental population. Overall, 26 QTL are identified; three are detected in multiple panels and are associated with starch-at-maturity, sucrose-at-maturity and NSC-at-heading. They tag OsHXK6 (rice hexokinase), ISA2 (rice isoamylase) and a tandem array of sugar transporters. This study provides the foundation for more in-depth molecular investigation to validate candidate genes underlying rice stem NSC and informs future comparative studies in other agronomically vital grass species.

Isoelectric focusing was used to investigate the distribution of enzymes exhibiting phosphoglucose isomerase, phosphoglucose mutase, malate dehydrogenase, esterase, hexokinase, glucose-6-phosphate dehydrogenase, peroxidase and fructose-1,6-bisphosphatase activities in a central Ontario population of the lichen Peltigera rufescens (Weis) Mudd. Samples of thalli were collected in order to estimate enzymatic variation in thalli collected within a site (separated by distances of 1-10 m) and between sites (separated by 5-15 km). A total of 85 different enzyme bands were identified in the 27 samples analysed. The results indicated that, at some locations, within site variation was as large as between site variation. The importance of this variation in the design of physiological studies of lichens is discussed.
