We present the first complete genome sequence of a copper-resistant biovar 5 strain of a bacterial pathogen of kiwifruit, Pseudomonas syringae pv. actinidiae. Comparison with the genome sequence of a copper-sensitive biovar 5 isolate indicates that copper resistance is encoded on a plasmid.

Pseudomonas syringae pv. actinidiae is the causal agent of bacterial canker of kiwifruit, a disease that has rapidly spread worldwide. We have fully sequenced and assembled the chromosomal and plasmid DNA from P. syringae pv. actinidiae ICMP 18884 using the PacBio RS II platform.

Pseudomonas syringae pv. actinidiae is a reemerging pathogen which causes bacterial canker of kiwifruit (Actinidia sp.). Since 2008, a global outbreak of P. syringae pv. actinidiae has occurred, and in 2010 this pathogen was detected in New Zealand. The economic impact and the development of resistance in P. syringae pv. actinidiae and other pathovars against antibiotics and copper sprays have ...

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 expressed in kiwifruit (Actinidia deliciosa) identified the gene AdGT4 which was highly expressed ...

Neutrophils are the body's primary defenders against invading pathogens. These cells migrate to loci of infection where they engulf micro-organisms and subject them to an array of reactive oxygen species and antimicrobial proteins to effect killing. Spent neutrophils subsequently undergo apoptosis and are cleared by macrophages, thereby resolving the inflammatory episode. Neutrophils contain hi...

decline in postharvest losses of kiwifruit depended to maintain of quality characteristics during storage and transportation. storage losses caused serious economic losses in kiwifruit. this study was conducted to inhibition of pathogen infection and increasing fruit quality of kiwifruit. hayward kiwifruits inoculated by b.cinerea conidia through pore wounds which formed by removal of the pedic...

to study the effects of postharvest treatments of spermidine and putrescine on storage quality of ‘hayward’ kiwifruit, the present research was performed. in november 2010, fruits were hand picked from fajr orchardist corporation in sari and transported to postharvest physiology laboratory. fruits were dipped for 4 minutes in either spermidine or putrescine solutions (0.5, 1.0 and 1.5 mm), and ...

Abstract In vitro-derived plants with elevated ploidy levels can display distinguishing features from the they are derived from, especially owing to their indirect regeneration. Genome size affects cell and, thus, plant morphological characteristics. Therefore, stomata traits may be used as a diagnostic feature allowing identification of ploidy. Actinidia chinensis var. deliciosa A. Chev. (A. C...

The plant growth regulator ethylene controls the onset of ripening in climacteric fruit (Schuch et al., 1989). Two enzymes are responsible for ethylene biosynthesis from its precursor S-adenosyl methionine: ACC synthase and ACC oxidase (Yang and Hoffman, 1984). Two cDNA clones, pTOM13 and pHTOM5, have been isolated from tomato and shown to encode ACC oxidase by expression in yeast (Hamilton et ...

BACKGROUND Dietary treatment is often recommended as the first line of treatment for women with mild iron deficiency. Although it is well established that ascorbic acid enhances iron absorption, it is less clear whether the consumption of ascorbic acid rich foods (such as kiwifruit) with meals fortified with iron improves iron status. The aim of this study is to investigate whether the consumpt...
