common (and generic) name is of obscure origin, but it was used by the French settlers in Florida as early as the sixteenth century. The tree is characteristically a plant of forest margins and clearings, but it also is often somewhat weedy, appearing in old fields, hedgerows, and along roadsides where it rapidly forms clumps by means of suckers and stolons. It is often thought of as being a ra...

The PIN family of trans-membrane proteins mediates auxin efflux throughout the plant and during various phases of plant development. In Arabidopsis thaliana, the PIN family comprised of 8 members, divided into "short" and "long" PINs according to the length of the hydrophilic domain of the protein. Based on sequence homology using the recently published potato genome sequence (Solanum tuberosum...

Plant lipoxygenases (LOXs) are a functionally diverse class of dioxygenases implicated in physiological processes such as growth, senescence, and stress-related responses. LOXs incorporate oxygen into their fatty acid substrates and produce hydroperoxide fatty acids that are precursors of jasmonic acid and related compounds. Here, we report the involvement of the tuber-associated LOXs, designat...

Tulipa edulis (Miq.) Baker is an important medicinal plant with a variety of anti-cancer properties. The stolon is one of the main asexual reproductive organs of T. edulis and possesses a unique morphology. To explore the molecular mechanism of stolon formation, we performed an RNA-seq analysis of the transcriptomes of stolons at three developmental stages. In the present study, 15.49 Gb of raw...

Reactive oxygen species (ROS), especially hydrogen peroxide, H2O2, act as signaling molecules to widely mediate growth, development, and stress response of plants. In the present study, internal ROS accumulation, effects exogenous H2O2 treatment, expression key tuberization-related genes, effect knockout Solanum tuberosum self-pruning 6A (StSP6A) on H2O2-induced tuber formation were investigate...

Calcium-dependent protein kinases, CDPKs, decode calcium (Ca2+) transients and initiate downstream responses in plants. In order to understand how CDPKs affect plant physiology, their specific target proteins must be identified. In tobacco, the bZIP transcription factor Repression of Shoot Growth (NtRSG) that modulates gibberellin (GA) content is a specific target of NtCDPK1. StCDPK3 from potat...

Licorice (Glycyrrhizae radix) is the roots and stolons of Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linnaeus in the Japanese Pharmacopoeia. Glycyrrhizae radix has been widely used as a sweetener and a traditional medicine. A Glycyrrhizae radix extract contains many constituents and has antispasmodic, antitussive, anti-ulcer, and anti-inflammatory effects. However, reports comparing th...

Allene oxide synthase (AOS) enzymes are members of the cytochrome P450 enzyme family, sub-family CYP74. Here we describe the isolation of three cDNAs encoding AOS from potato (StAOS1-3). Based on sequence comparisons, they represent members of either the CYP74A (StAOS1 and 2) or the CYP74C (StAOS3) sub-families. StAOS3 is distinguished from the other two AOS isoforms in potato by its high subst...

Zoysiagrass (Zoysia japonica Steud.) is commonly found in temperate climate regions and widely used for lawns, in part, owing to its uniform green color. However, some zoysiagrass cultivars accumulate red to purple pigments in their spike and stolon tissues, thereby decreasing the aesthetic value. Here we analyzed the anthocyanin contents of two zoysiagrass cultivars 'Anyang-jungji' (AJ) and 'G...
