Poinsettia is an economically important ornamental potted plant in which certain bract colour variants are often obtained by mutation breeding. Previously, poinsettia, we identified Bract1, a GST gene involved the sequestration and transport of anthocyanins to vacuole. This carries short, highly mutable 4-bp repeat its coding region. Loss one unit leads loss function for homozygous mutants, ant...

A major component of the evaluation of biological control agents is the study and comparison of their biology, including the reproductive mode. In hymenopteran parasitoids, reproductive modes include thelytoky and arrhenotoky. Since a thelytokous population produces only females, it is assumed that they may be better suited for biological control than an arrhenotokous population. Here we compar...

Background: Euphorbia pulcherrima is highly ornamental value of poinsettia flower, which posses colorful bracts and low temperature resistant leave. Its embryos or adventitious buds were cultivated mainly from stems, petioles tender buds. The cultivation seedlings studied firstly for improving the quality Poinsettia. Methods: A rapid reproducible regeneration system leaves stems with has been e...

Abstract Background Mutation breeding is an extraordinary tool in plant to increase the genetic variability, where mutations anthocyanin biosynthesis are targets generate distinctive phenotypes ornamental species. In poinsettia, ionizing radiation routinely applied programs obtaining a range of colours, with nearly all pink and white varieties being obtained after γ- or X-ray mutagenesis red va...

Bemisia tabaci (Gennadius) is an economically important pest of agricultural and ornamental plants worldwide and is now widely recognized as a cryptic species complex. In North America, B. tabaci is a particularly important pest of greenhouse poinsettia. In poinsettia production, two cryptic species from the B. tabaci complex, Mediterranean and Middle East Minor 1, often infest crops simultaneo...

BACKGROUND Bemisia tabaci, a polyphagous insect with over 900 host plants, is an effective vector of more than 100 plant viruses. Being highly fecund, B. tabaci has the potential to develop insecticide resistance rapidly, as demonstrated by reports of use failures with MEAM1 and MED cryptic species (commonly known as biotypes B and Q respectively). Insecticide resistance management is a key com...
