APETALA2/ethylene-responsive factor superfamily (AP2/ERF) is a transcription factor involved in abiotic stresses, for instance, cold, drought, and low oxygen. In this study, a novel ethylene-responsive transcription factor named AdRAP2.3 was isolated from Actinidiadeliciosa

The multistage induction theory is generally regarded as the mechanism of carcinogenesis. In order to prevent the initiation stage of carcinogenesis, it is meaningful to discover the functional components of edible plants. The objective of this research was to test the antimutagenicity of the

Plant infection by a virus is a complex process influenced by virus-encoded factors and host components which support replication and movement. Critical factors for a successful tobamovirus infection are the viral movement protein (MP) and the host pectin methylesterase (PME), an important plant

Glycosides are an important potential source of aroma and flavour compounds for release as volatiles in flowers and fruit. The production of glycosides is catalysed by UDP-glycosyltransferases (UGTs) that mediate the transfer of an activated nucleotide sugar to acceptor aglycones. A screen of UGTs

The gene encoding L-galactose-1-phosphate phosphatase (GPP) plays a central role in ascorbic acid (AsA) biosynthesis in plants. Here, we report AsA contents, GPP expression, and functioning of its promoter in response to light, exogenous stress-signalling hormones, or abiotic stresses in kiwifruit

Kiwifruit bacterial canker, caused by the bacterial pathogen Pseudomonas syringae pv. actinidiae (Psa), is a destructive disease in the kiwifruit industry globally. Consequently, understanding the mechanism of defense against pathogens in kiwifruit could facilitate the development of

Actinidia arguta is commercially grown in New Zealand and few other countries; the fruit are sometimes sold as kiwiberry or hardy kiwi. In New Zealand, two biovars of Pseudomonas syringae pv. actinidiae have recently been found to cause bacterial canker on both A. chinensis and A. deliciosa, which

During the springs from 2006 to 2008, a new disease was observed on 4- to 5-year-old Actinidia chinensis (cv. Jin Tao) trees in different commercial kiwifruit-production areas in northern Italy (Lombardy). Initially, disease occurrence was sporadic but later became widespread. Symptoms on flowers

Chlorophyll is present in many plant organs, including immature fruit where it is usually degraded during ripening. Mature green kiwifruit (Actinidia deliciosa) are an exception, with high concentrations of chlorophyll remaining in the fruit flesh. In gold-fleshed kiwifruit (A. chinensis),

Two co-infecting novel vitiviruses from Actinidia chinensis were identified from mechanically inoculated Nicotiana occidentalis. Both virus genomes were sequenced and share 64% nucleotide identity. Their overall structure is typical of vitiviruses, with five open reading frames (ORFs) and a

Terpene volatiles are found in many important fruit crops but their relationship to flavor is poorly understood. Here we demonstrate using sensory descriptive and discriminant analysis that 1,8-cineole contributes a key floral/eucalyptus note to the aroma of ripe 'Hort16A' kiwifruit (Actinidia

A ssRNA virus from kiwifruit (Actinidia spp.) was identified as a member of the family Betaflexiviridae. It was mechanically transmitted to the herbaceous indicators Nicotiana benthamiana, N. clevelandii, N. glutinosa and N. occidentalis. The complete genome was comprised of three ORFs and a 3'poly

The objective of this research was to examine the radical scavenging activity of traditional Japanese herbs. Samples used in the experiments were gennoshoko (Geranium nepalense var. thunbergii), yomogi (Artemisia vulgaris var.indica), senburi (Swertia japonica), iwa-tobacco (Conandron ramondioides),

Trehalose metabolism and its intermediate trehalose-6-phosphate (T6P) are implicated in sensing and signalling sucrose availability. Four class I TREHALOSE-6-PHOSPHATE SYNTHASE (TPS1) genes were identified in kiwifruit, three of which have both the TPS and trehalose-6-phosphate phosphatase (TPP)

Anthocyanins are a group of secondary metabolites that colour fruit and flowers orange, red, purple or blue depending on a number of factors, such as the basic structure, co-pigmentation, metal ion complexation and vacuolar pH. The biosynthesis of anthocyanin is regulated at the transcriptional
