spirodela punctata/ニコチン

We have studied the mechanism of UV protection in two duckweed species (Lemnaceae) by exploiting the UV sensitivity of photosystem II as an in situ sensor for radiation stress. A UV-tolerant Spirodela punctata G.F.W. Meyer ecotype had significantly higher indole-3-acetic acid (IAA) levels than a

We have used a variety of methods to localize the genes for ribosomal proteins S7 and S12 on Spirodela chloroplast DNA. Heterologous hybridization with a rps12 gene specific probe from Euglena has revealed the presence of rps12 homologous sequences within the inverted repeat of Spirodela chloroplast

In order to determine the localization of ribosomal protein genes on the chloroplast genome of Spirodela, we have followed two different approaches: First, antisera were prepared against purified 30S, 50S and 70S chloroplast ribosomal proteins from Spinacia. These antisera react with about two third
