Wheat and barley contain at least four classes of starch synthases in the endosperm, granule bound starch synthase I (GBSSI) and starch synthases I, II and III (SSI, SSII, SSIII). In this work, SSII in barley is shown to be associated with the starch granule by using antibodies. A cDNA from barley encoding SSII and the genes for SSII from barley and(More)

 The most important commercial coffee species, Coffea arabica, which is cultivated in about 70% of the plantations world-wide, is the only tetraploid (2n=4x=44) species known in the genus. Genomic in situ hybridization (GISH) and fluorescent in situ hybridization (FISH) were used to study the genome organization and evolution of this species. Labelled total(More)
Radiation-induced wheat-rye chromosome translocation lines resistant to Hessian fly, Mayetiola destructor (say), were analyzed by in situ hybridization using total genomic and highly repetitive rye DNA probes pSc119 and pSc74. In situ hybridization analysis revealed the exact locations of the translocation breakpoints and allowed the estimation of the sizes(More)
Introduction of large-DNA fragments into cereals by Agrobacterium-mediated transformation is a useful technique for map-based cloning and molecular breeding. However, little is known about the organization and stability of large fragments of foreign DNA introduced into plant genomes. In this study, we produced transgenic rice plants by(More)
To examine the role of isoamylase1 (ISA1) in amylopectin biosynthesis in plants, a genomic DNA fragment from Aegilops tauschii was introduced into the ISA1-deficient rice (Oryza sativa) sugary-1 mutant line EM914, in which endosperm starch is completely replaced by phytoglycogen. A. tauschii is the D genome donor of wheat (Triticum aestivum), and the(More)
Studies of maize starch branching enzyme mutants suggest that the amylose extender high amylose starch phenotype is a consequence of the lack of expression of the predominant starch branching enzyme II isoform expressed in the endosperm, SBEIIb. However, in wheat, the ratio of SBEIIb and SBEIIa expression are inversely related to the expression levels(More)
Due to the ease with which chromosomes can be observed, the Allium species, and onion in particular, have been familiar materials employed in cytogenetic experiments in biology. In this study, centromeric histone H3 (CENH3)-coding cDNAs were identified in four Allium species (onion, welsh onion, garlic and garlic chives) and cloned. Anti-CENH3 antibody was(More)
Non-flagellated vegetative green algae of the Trebouxiophyceae propagate mainly by autosporulation. In this manner, the mother cell wall is shed following division of the protoplast in each round of cell division. Binary fission type Nannochloris and budding type Marvania are also included in the Trebouxiophyceae. Phylogenetic trees based on the actin(More)
A robust image processing technique capable of detecting and localizing objects accurately plays an important role in many computer vision applications. In this paper, a feature based detector for birds is proposed. By combining Histogram of Oriented Gradients (HOG) and Center-Symmetric Local Binary Pattern (CS-LBP) as the feature set, detection of crows(More)
