Polyamine biosynthesis of apple callus under salt stress: importance of the arginine decarboxylase pathway in stress response.
To clarify the involvement of the arginine decarboxylase (ADC) pathway in the salt stress response, the polyamine titre, putrescine biosynthetic gene expression, and enzyme activities wereExpand

Expression of arginine decarboxylase and ornithine decarboxylase genes in apple cells and stressed shoots.
Arginine decarboxylase (ADC) and ornithine decarboxylase (ODC) are two important enzymes responsible for putrescine biosynthesis. In this study, a full-length ADC cDNA (MdADC) was isolated from appleExpand

Molecular cloning and functional characterization of two apple S-adenosylmethionine decarboxylase genes and their different expression in fruit development, cell growth and stress responses.
Two full-length S-adenosylmethionine decarboxylase (SAMDC) cDNAs, MdSAMDC1 and MdSAMDC2, were isolated from apple [Malus sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.]. Both cDNAs encoded tinyExpand

Role of polyamines in peach fruit development and storage.
To investigate the role of polyamines in pre- and post-harvest fruit development of 'Akatsuki' peach (Prunus persica (L.) Batsch.) we measured polyamine concentrations, activities of polyamineExpand

Two types of spermine synthase gene: MdACL5 and MdSPMS are differentially involved in apple fruit development and cell growth.
Three cDNAs with high homology to spermine (Spm) synthases in Arabidopsis were isolated from apple [Malus sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.]. MdACL5-1 and MdACL5-2 have highExpand

Interrelationship between polyamine and ethylene in 1‐methylcyclopropene treated apple fruits after harvest
To investigate the interrelationship between polyamine and ethylene, apple fruits (Malus domestica Borkh.) were treated with 1-methylcyclopropene (1-MCP). Without 1-MCP treatment, ethylene productionExpand

Identification of polyamine oxidase genes from apple and expression analysis during fruit development and cell growth
Two cDNAs (MdPAO1 and MdPAO2a) encoding polyamine oxidases (PAOs) were isolated from apple. Some notable features related to substrate specificity, catalytic activity and localization of MdPAO wereExpand

Apple aminopropyl transferase, MdACL5 interacts with putative elongation factor 1-α and S-adenosylmethionine synthase revealed
Abstract Several lines of evidence suggest different allocations of the physiological roles of aminopropyl transferase genes, SPMS and ACL5 in plants. To get deeper insights into the physiologicalExpand

Nuclear localization of sweet cherry DREB1/CBF ortholog (CIG) and low temperature-inducible activity of CIG promoter
The fluorescent signal of GFP fused to CIG-B, which is one of the three DREB1/CBF (dehydration responsive element binding protein 1/C-repeat binding factor) homologs isolated from sweet cherry, wasExpand
