Molecular Weight Heterogeneity

The quaternary structures of ribulose-1, 5-bisphosphate carboxylase–oxygenase from cold-hardened and unhardened Puma rye were examined by two-dimensional gel electrophoresis according to the method of O'Farrell. The results indicate that major changes in charge heterogeneity occur in the large subunit of this enzyme during growth at cold-hardening temperatures. The extent of charge heterogeneity decreased upon adaptation of Puma rye to cold-hardening temperatures. In addition to charge heterogeneity, molecular weight heterogeneity was also evident in the large subunit polypeptides of the enzyme from cold-hardened and unhardened Puma rye.

Hydrangea and Schizophragma are popular horticultural and ornamental plants. This study was designed to identify unknown accessions of Hydrangeaceae that have leaf morphological characters different from Hydrangeaanomala subsp. petiolaris and Schizophragma hydrangeoides in Jeju, Korea. A total of 29 accessions of Hydrangea and Schizophragma from the wild were collected and analyzed using randomly amplified polymorphic DNA (RAPD) and single nucleotide polymorphisms (SNPs) from the ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit (rbcL) gene. Morphological characteristics of leaves and shoot apices of several accessions were also examined. Based on the RAPD markers, SNPs of the (rbcL) gene and morphological characteristics of apical buds, the unknown accessions were identified as H. anomala var. petiolaris.

Dimensional Distribution

As shown previously, Euglena cells grown in Hutner’s medium in the dark without agitation accumulate wax as well as paramylum, and contain proplastids showing no internal structure except for a single prothylakoid existing close to the envelope. When the cells are transferred to an inorganic medium containing ammonium salt and the cell suspension is aerated in the dark, the wax was oxidatively metabolized, providing carbon materials and energy 23 for some dark processes of plastid development. Under these conditions, pyrenoid-like structures (called “pro-pyrenoids”) are formed at the sites adjacent to the prolamel larbodies (PLB) localized in the peripheral region of the proplastid. The single prothylakoid becomes paired with a newly formed prothylakoid, and a part of the paired prothylakoids is extended, with foldings, in to the “propyrenoid”. In this study, we observed a concentration of RuBisCO in the “propyrenoid” of Euglena gracilis strain Z using immunoelectron microscopy.
