Polyhydroxybutyrate-co-hydroxyvalerate (PHBV) is a polyhydroxyalkanoate (PHA) bioplastic group with thermoplastic properties is thus high in quality and can be degradable. PHBV can be produced by bacteria, but the process is not economically competitive with polymers produced from petrochemicals. To overcome this problem, research on transgenic plants has been carried out as one of the solution...

Transient assay systems using protoplasts have been utilized in several plant species and are a powerful tool for rapid functional gene analysis and biochemical manipulations. A protoplast system has not been used in switchgrass (Panicum virgatum L.), even though it is a bioenergy crop that has received considerable attention. Here we report the first protocol to isolate large numbers of viable...

The shoot apical meristem (SAM) of seed plants is the site at which lateral organs are formed. Once organ primordia initiate from the SAM, they establish polarity along the adaxial-abaxial, proximodistal and mediolateral axes. Among these three axes, the adaxial-abaxial polarity is of primary importance in leaf patterning. In leaf development, once the adaxial-abaxial axis is established within...

To investigate the regulation of genes encoding CAB proteins in cotton (Gossypium hirsutum) and identify potentially useful promoters, we determined the structure and expression of two genes (Lhcbl*Z and Lhcb3*l) encoding type I and type 111 proteins of the LHCII subfamily (Table I). Northern analyses of the gene expression pattem in cotton demonstrated substantial LHCII transcript accumulation...

Arabidopsis pinoid mutants show a strong phenotypic resemblance to the pin-formed mutant that is disrupted in polar auxin transport. The PINOID gene was recently cloned and found to encode a protein-serine/threonine kinase. Here we show that the PINOID gene is inducible by auxin and that the protein kinase is present in the primordia of cotyledons, leaves and floral organs and in vascular tissu...

Scientific achievement in molecular biology and genetic engineering have made it possible to create new methods of selection k that are based on genome modification. Todays, more genetically modified plants being intensively tested the field, but their influence has not yet been fully studied environment, biodiversity, human health, animal body.
