Comparative studies on stem anatomical structure of rice plants with various ploidy level
To investigate the effects of ploidy changes on the stem structure, by using flow cytometry (FCM), we distinguished six different ploidy materials (haploid, diploid, and triploid of line FC311 and haploid, diploid, and tetraploid of line FC322), in rice (Oryza sativa L. subsp. Japonica). Also, we co...

| description | To investigate the effects of ploidy changes on the stem structure, by using flow cytometry (FCM), we distinguished six different ploidy materials (haploid, diploid, and triploid of line FC311 and haploid, diploid, and tetraploid of line FC322), in rice (Oryza sativa L. subsp. Japonica). Also, we compared the anatomical stem structure of various ploidy rice plants with paraffin sections. The results show that the increase of the number and size of vascular bundle, and area of stem wall and vascular bundle in internodes were frequently associated with increase in ploidy level of the tested plants, indicating a significant gene dosage effect. However, there were no obvious correlations between different ploidy levels and the following traits, such as, layer number and development of collenchyma cell under epiderm in vascular bundle sheath of outer circle and inner circle, starch grains in ground tissue cells, the ratio of total area of vascular bundle and area of stem wall. The structure of two layers of collenchyma cell was rarely observed in the 1st internode of FC322 tetraploid plant. |
