“…Peach DAM1, DAM2, and DAM4 were most closely associated with terminal bud formation (Li et al, 2009), whereas peach DAM5 and DAM6 expression was negatively correlated with the time required for terminal bud break in peach (Jimenéz et al, 2010). Negative correlation of peach PpDAM5 and PpDAM6 expression with the time required for bud break was also reported for lateral vegetative (Yamane et al, 2011a) and flower (Yamane et al, 2011b, c) buds. In other temperate fruit trees, down-regulation of the SVP-like gene during dormancy release has been reported in raspberry (Rubus idaeus L.) (Mazzitelli et al, 2007).…”

“…However, questions remain as to whether DAMs play a central role in bud dormancy regulation of Japanese apricot and peach. Firstly, DAMs expression levels were not affected when low-chill peach dormancy was broken by dormancy breaking reagent, cyanamide, in October (Hosaka et al, 2012), although cyanamide could decrease DAM expression when high-chill peach dormancy was broken by cyanamide in December (Yamane et al, 2011a). Secondly, in the early flowering Japanese apricot cultivar 'Taoxingmei', digital expression of DAMs in flower buds was maintained at high levels in ecodormancy (Jan.) in comparison to that observed in endodormancy (Dec.), and decreased during February (Zhong et al, 2013).…”

Bud dormancy allows most deciduous fruit tree species to avoid injury in unsuitable environments, synchronize their annual growth, and adapt to a temperate zone climate. Because bud dormancy affects next season's fruit production and vegetative growth, it is considered one of the most important physiological factors that control fruit production. Recent global climate changes require us to better understand the genetic factors regulating bud dormancy, especially those that induce dormancy release and subsequent bud break. In this review, environmental factors that affect the seasonal dormancy depth of Japanese apricot (P. mume Siebold & Zucc.) and peach [P. persica (L.) Batsch] are first outlined. Next, recent progress of genetic, biochemical, and molecular biological studies of Prunus dormancy regulation is described. Recent advances in functional genomics have promoted the discovery of gene function and gene networks associated with bud dormancy regulation. A group of candidate genes for bud dormancy regulation, the DORMANCY-ASSOCIATED MADS-box (DAM) genes in Prunus, are focused. Recently reported expressional analysis suggests a significant role for DAMs in dormancy release and bud break of Japanese apricot and peach vegetative buds. Transformation studies of PmDAM6 have demonstrated that it has an inhibitory effect on the apical growth of poplar (Populus spp.). As bud dormancy is a quantitative polygenic trait, not only DAMs, but also other genes and gene networks appear to regulate bud dormancy. Ongoing and future studies will undoubtedly facilitate the unveiling of the molecular aspects of bud dormancy regulation in temperate fruit tree species of Prunus.

“…Young leaves of the apricot and Japanese apricot seedlings were collected, immediately frozen in liquid nitrogen, and stored at -80°C until use. Total RNA was extracted from the collected leaves using the hexadecyltrimethyl-ammonium bromide (CTAB) method and cDNA was synthesized as described in Yamane et al (2011). Seeds of apricot and Japanese apricot were rinsed under running tap water overnight, placed on a layer of filter paper moistened with distilled water in petri dishes, and germinated under 4°C, dark conditions.…”

Apple latent spherical virus (ALSV) vectors have been shown to effectively induce stable virus-induced gene silencing (VIGS) in a wide range of plant species, including rosaceous fruit tree species such as apple (Malus × domestica Borkh.), pear (Pyrus communis L.), and Japanese pear (P. pyrifolia Nakai). In this study, we attempted to develop a VIGS-based gene evaluation system for two Prunus fruit tree species, apricot and Japanese apricot, using ALSV vectors. A partial sequence of the P. armeniaca PHYTOENE DESATURASE (ParPDS) gene was cloned and ligated into the T-DNA region of a binary vector, pBICAL2, designed based on RNA2 of ALSV. The resultant pBICAL2-ParPDS was introduced into a disarmed Agrobacterium strain, EHA105. pBICAL1, a binary plasmid for the expression of ALSV RNA1 in plants, was also introduced into EHA105. Leaves of Nicotiana benthamiana were infected with pBICAL1/EHA105 and pBICAL2-ParPDS/EHA105 simultaneously to produce and amplify recombinant ALSV particles. The amplified ParPDS-ALSV in N. benthamiana was isolated and infected into the cotyledons of apricot and Japanese apricot seedlings by particle bombardment. Although our attempts to infect wild and recombinant ALSVs into Japanese apricot seedlings were unsuccessful, uniform discoloration of the upper leaves, a typical phenotype of PDS knock down, was observed several weeks after inoculation in apricot seedlings. We discuss the possible use of this VIGS-based gene evaluation system in Prunus.

“…Furthermore, overexpression of CEN/TFL1 in Populus causes delayed bud break and altered chilling requirements (Mohamed et al 2010). Aintegumenta-like genes (regulators of cell division) and dormancy-induced MADS-box genes are downstream targets of CO/FT (Karlberg et al 2011;Yamane et al 2011). Additional downstream effects related to dormancy induction are the upregulation of genes associated with cold hardiness and drought, defense, carbohydrate synthesis and transport, cell wall biosynthesis or modification as well as RNA metabolism and chromatin modification/remodeling (Ruttink et al 2007;Park et al 2008;Ko et al 2011).…”

Tracing a key player in the regulation of plant architecture: the columnar growth habit of apple trees (Malus × domestica)

Plant architecture is regulated by a complex interplay of some key players (often transcription factors), phytohormones and other signaling molecules such as microRNAs. The columnar growth habit of apple trees is a unique form of plant architecture characterized by thick and upright stems showing a compaction of internodes and carrying short fruit spurs instead of lateral branches. The molecular basis for columnar growth is a single dominant allele of the gene Columnar, whose identity, function and gene product are unknown. As a result of marker analyses, this gene has recently been fine-mapped to chromosome 10 at 18.51-19.09 Mb [according to the annotation of the apple genome by Velasco (2010)], a region containing a cluster of quantitative trait loci associated with plant architecture, but no homologs to the well-known key regulators of plant architecture. Columnar apple trees have a higher auxin/ cytokinin ratio and lower levels of gibberellins and abscisic acid than normal apple trees. Transcriptome analyses corroborate these results and additionally show differences in cell membrane and cell wall function. It can be expected that within the next year or two, an integration of these different research methodologies will reveal the identity of the Columnar gene. Besides enabling breeders to efficiently create new apple (and maybe related pear, peach, cherry, etc.) cultivars which combine desirable characteristics of commercial cultivars with the advantageous columnar growth habit using gene technology, this will also provide new insights into an elevated level of plant growth regulation.
