Organellar Genomes of White Spruce (Picea glauca): Assembly and Annotation.
The genome sequences of the plastid and mitochondrion of white spruce (Picea glauca) were assembled from whole-genome shotgun sequencing data using ABySS. The sequencing data contained reads from both the nuclear and organellar genomes, and reads of the organellar genomes were abundant in the data as each cell harbors hundreds of mitochondria and plastids. Hence, assembly of the 123-kb plastid ...
متن کاملShoot-Forming Cultures of White Spruce (Picea glauca) Buds1
Nitrogen-14 and nitrogen-15 nuclear magnetic resonance (NMR) spectra were recorded for freshly dissected buds of Picea glauca and for buds grown for 3, 6 and 9 weeks on shoot-forming medium. Resonances for Glu (and other aNH2 groups), Pro, Ala, and the side chain groups in Gin, Arg, Om, and 'y-aminobutyric acid could be detected in in vivo 15N NMR spectra. Peaks for aamino groups, Pro, N03and N...
متن کاملSeasonal air and soil temperature effects on photosynthesis in red spruce (Picea rubens) saplings.
Net photosynthesis and stomatal conductance were measured in ten red spruce (Picea rubens Sarg.) saplings, growing near Ithaca, New York, throughout the early spring and late-fall growing periods. Gas exchange and daily minimum and maximum soil and air temperatures were also measured. Linear regression analysis showed that rates of net photosynthesis were positively correlated with both minimum...
متن کاملThe effect of reduced glutathione on morphology and gene expression of white spruce (Picea glauca) somatic embryos.
Inclusions of reduced glutathione (GSH) in the maturation medium increased the conversion frequency of white spruce somatic embryos without the need of a partial drying treatment (PDT). This beneficial effect was the result of major alterations in morphology and gene expression during the maturation period. Compared with control embryos, GSH-treated embryos showed a differential accumulation of...
متن کاملModular organization of the white spruce (Picea glauca) transcriptome reveals functional organization and evolutionary signatures
Transcript profiling has shown the molecular bases of several biological processes in plants but few studies have developed an understanding of overall transcriptome variation. We investigated transcriptome structure in white spruce (Picea glauca), aiming to delineate its modular organization and associated functional and evolutionary attributes. Microarray analyses were used to: identify and f...
