摘要:

AbstractThis review provides a current perspective on the insertion of genes into plants. Some of the knowledge on the structure and control of plant genes gained recently from genetic engineering approaches is described, together with developments that can be expected to emerge from further exploitation of gene transfer techniques.

摘要:

AbstractLight effects on the activity of several genes have recently been exploited in studies of plant gene expression. We discuss here some examples involving nuclear genes of higher plants, with emphasis on responses mediated by the phytochrome system. Recent work has revealed considerable diversity in the responses of different genes, indicating that several different regulatory programs are probably involved. A start has been made in studies of nuclear events associated with the changes in expression. Transcriptional regulation almost certainly occurs, although many details remain to be studied and effects on mRNA processing and turnover have not been ruled out. Recent in vitro mutagenesis and gene transfer experiments with the gene for the small subunit of RuBP carboxylase indicate that sequences involved in regulating the level of expression in the light are located 5′ to the gene within about 1 kb of the start of transcriptio

摘要:

AbstractBiochemical and genetical analysis of plant transposons has shown that these elements can induce unstable mutations and also that the transposon structure can be altered in different ways. Upon insertion, a transposon can give rise to a variety of chromosomal changes in the vicinity of the insertion site. The alterations range from the nucleotide level to large‐scale rearrangement

摘要:

AbstractWork with plant cell cultures has developed rapidly in recent years, progress being manifested particularly by the development of commercial process technology for the synthesis of selected natural products. The economics of operating a plant‐cell culture process are, however, still questionable, and a great deal still needs to be done to strengthen the underlying science before the technology can be regarded as industrially commonplace. Nonetheless, the great versatility of plants as centres of chemical synthesis suggests that, with appropriate developments in cell culture technology, this area may have a significant role to play in the fine chemicals industry of the futur

摘要:

AbstractThe existence and properties of the chloroplast genome were established by a combination of genetic methods which identified chloroplast mutations and placed them into a linear sequence or map; and by chemical methods, CsCl density gradient ultracentrifugation and base analysis, which identified non‐nuclear DNA extracted from isolated chloroplasts. These studies, carried out in the 1950s and 1960s, primarily with Chlamydomonas, as well as parallel studies of mitochondrial DNA with yeast and Neurospora, laid the framework for distinguishing organelle and nuclear genomes. On this basis, the coding and regulatory functions of three genomes – nuclear, chloroplast, and mitochondrial – are being addressed in modern plant molecular bi
