Rice Genome Research: An Alternative Approach Based on Molecular Cytology
A genome is a collection of chromosomes and visible chromosomes under a photomicroscope that provide a unique and effective approach to genome analysis. In situ hybridization (ISH) is one of the most effective me...

Chromosome painting as a tool for rice genetics and breeding
Chromosome painting and genomic in situ hybridization (GISH) are both effective methods for basic genetic research and practical breeding. These methods were applied even in the typically small chromosomes of ric...

Trends in site-number change of rDNA loci during polyploid evolution in Sanguisorba (Rosaceae)
To elucidate the evolutionary dynamics of rDNA site number in polyploid plants, we determined 5S and 18S-5.8S-26S rDNA sites for ten species of Sanguisorba (2n=14, 28, 56) and a single species of each of three o...

Chromosome maps of legumes
Legumes are of immense importance as food and feed, and for sustainable agriculture, due to their ability to fix nitrogen. Here, the chromosome maps of the legumes soybean (Glycine max), Lotus (Lotus japonicus), ...

Integration of cytogenetic and genetic linkage maps of Lotus japonicus, a model plant for legumes
To construct a high-resolution pachytene chromosome map, we used the chromosome image analyzing system version 3 and fluorescence in situ hybridization. Two ribosomal RNA genes (45S rDNA and 5S rDNA), two major t...

Molecular insights into the non-recombining nature of the spinach male-determining region
Spinach (Spinacia oleracea L.) is a dioecious plant with male heterogametic sex determination and homomorphic sex chromosomes (XY). The dioecism is utilized for producing commercial hybrid seeds, and hence unders...

Global epigenetic changes of histone modification under environmental stresses in rice root
Abiotic stresses are non-living factors with negative morphological and physiological effects on living organisms. Substantial evidence exists that gene expression changes during plant cell growth are regulate...

Surface structures consisting of chromatin fibers in isolated barley (Hordeum vulgare) chromosomes revealed by helium ion microscopy
The chromosome compaction of chromatin fibers results in the formation of the nucleosome, which consists of a DNA unit coiled around a core of histone molecules associated with linker histone. The compaction o...
