laccase/nicotiana

A biotechnological approach was applied to reduce phenol content in olive mill wastewaters by transgenic tobacco plants. The cDNA laccase of poxC gene from Pleurotus ostreatus, carrying its own signal peptide for extracellular secretion, was transferred into the Nicotiana tabacum genome. Transgenic

Malachite green (MG) was decolorized by laccase (LacA) of white-rot fungus Cerrena sp. with strong decolorizing ability. Decolorization conditions were optimized with response surface methodology. A highly significant quadratic model was developed to investigate MG decolorization with LacA, and the

In contrast to the detailed molecular knowledge available on anthocyanin synthesis, little is known about its catabolism in plants. Litchi (Litchi chinensis) fruit lose their attractive red color soon after harvest. The mechanism leading to quick degradation of anthocyanins in the pericarp is not

Laccase (EC 1.10.3.1) activity was measured in regenerating and non-regenerating protoplasts isolated from tobacco (Nicotiana tabacum, L.) leaves. Laccase activity diminished soon after isolation: thereafter,it steadily increased in regenerating protoplasts during a 6-day culture period, whereas it

A cell suspension culture of a tobacco (Nicotiana tabacum L. cv. Petit Havana) cell line derived from a cultivar transformed with the Tcyt gene from Agrobacterium, which leads to high endogenous levels of cytokinin, has been established. This cell line shows increased cell aggregation, elongated

RNA-dependent RNA polymerase 1 of Nicotiana tabacum modulates ToLCGV pathogenesis by influencing a number of defence-related genes in N. benthamiana plants. Key means of plants protecting themselves from the invading viruses is through RNA silencing. RNA-dependent RNA polymerase-1 (RDR1) is one of
