Virus-induced gene silencing unravels multiple transcription factors involved in floral growth and development in Phalaenopsis orchids
Orchidaceae, one of the largest angiosperm families, has significant commercial value. Isolation of genes involved in orchid floral development and morphogenesis, scent production, and colouration will advance knowledge of orchid flower formation and facilitate breeding new varieties to increase the commercial value. With high-throughput virus-induced gene silencing (VIGS), this study identifie...
متن کاملDevelopment of Phalaenopsis Orchids for the Mass-Market
INTRODUCTION It is widely recognized that potted Phalaenopsis production has increased tremendously in last few years. The specific statistics for Phalaenopsis are not available, for the US Department of Agriculture only keep records on total orchid production and sales. However, over 75% of all orchids sold are Phalaenopsis (American Orchid Society, pers. commun.). In 2000, wholesale orchid sa...
متن کاملPyrrolizidine alkaloid biosynthesis in Phalaenopsis orchids: developmental expression of alkaloid-specific homospermidine synthase in root tips and young flower buds.
Pyrrolizidine alkaloids (PAs) are typical compounds of plant secondary metabolism and are believed to be part of the plant's chemical defense. Within the monocotyledonous plants, PAs have been described in only a few genera, mainly orchids, including Phalaenopsis. Because phylogenetic analyses suggest an independent origin of PA biosynthesis within the monocot lineage, we have analyzed the deve...
متن کاملFloral scent emitted by white and coloured morphs in orchids.
Polymorphism of floral signals, such as colour and odour, is widespread in flowering plants and often considered to be adaptive, reflecting various pollinator preferences for particular floral traits. Several authors have recently hypothesized that particular associations exist between floral colour and scent, which would result from shared biochemistry between these two floral traits. In this ...
متن کاملMenthofuran regulates essential oil biosynthesis in peppermint by controlling a downstream monoterpene reductase.
(+)-Pulegone is a central intermediate in the biosynthesis of (-)-menthol, the most significant component of peppermint essential oil. Depending on environmental conditions, this branch point metabolite may be reduced to (-)-menthone en route to menthol, by pulegone reductase (PR), or oxidized to (+)-menthofuran, by menthofuran synthase (MFS). To elucidate regulation of pulegone metabolism, we ...
