“…The SNP marker S2_18992724y is located approximately in the same position as a ParSOC1 gene that has already been described as being linked to chilling requirements in apricot (Olukolu et al 2009;Trainin et al 2013). Furthermore, relatively high correlation has been observed between chilling requirements and specific ParSOC1 alleles (Trainin et al 2013).…”

Reproductive phenological traits of great agronomical interest in apricot species, including flowering date, ripening date and fruit development period, were studied during 3 years in two F 1 progenies derived from the crosses 'Bergeron' × 'Currot' (B × C) and 'Goldrich' × 'Currot' (G × C). Results showed great variability and segregation in each population, confirming the polygenic nature and quantitative inheritance of all the studied traits. Genetic linkage maps were constructed combining SSR and SNP markers, using 87 markers in the 'B × C' population and 89 markers in 'G × C'. The genetic linkage maps in both progenies show the eight linkage groups (LGs) of apricot, covering a distance of 394.9 cM in 'Bergeron' and of 414.3 cM in 'Currot'. The 'Goldrich' and 'Currot' maps were of 353.5 and 422.3 cM, respectively. The average distance obtained between markers was thus 7.59 cM in 'Bergeron' and 7.53 cM in 'Currot', whereas the 'Goldrich' and 'Currot' averages were 5.6 and 7.5 cM, respectively. According to the polygenic nature of the studied phenology traits, QTLs linked to flowering date, ripening date and the fruit development period were identified during the 3 years of the study in all LGs except for LG 8. Among the QTLs identified, major QTLs for flowering and ripening date and the fruit development period were identified in LG 4, especially important in the 'G × C' population.

“…We performed a maximum likelihood phylogenetic analysis using randomized axelerated maximum likelihood (Stamatakis et al, 2008), which showed that Fv SOC1 groups with other known SOC1 homologs from Rosaceae (e.g., Trainin et al, 2013), within the same clade as SOC1 homologs from other rosids (e.g., Hecht et al, 2005; see Supplemental Figure 1 and Supplemental Data Set 1 online). Moreover, a syntenic view generated by CoGe (Lyons and Freeling, 2008) showed that the microsynteny around SOC1 and Fv SOC1 is conserved (see Supplemental Figure 2 online).…”

In the annual long-day plant Arabidopsis thaliana, SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1) integrates endogenous and environmental signals to promote flowering. We analyzed the function and regulation of the SOC1 homolog (Fragaria vesca [Fv] SOC1) in the perennial short-day plant woodland strawberry (Fragaria vesca). We found that Fv SOC1 overexpression represses flower initiation under inductive short days, whereas its silencing causes continuous flowering in both short days and noninductive long days, similar to mutants in the floral repressor Fv TERMINAL FLOWER1 (Fv TFL1). Molecular analysis of these transgenic lines revealed that Fv SOC1 activates Fv TFL1 in the shoot apex, leading to the repression of flowering in strawberry. In parallel, Fv SOC1 regulates the differentiation of axillary buds to runners or axillary leaf rosettes, probably through the activation of gibberellin biosynthetic genes. We also demonstrated that Fv SOC1 is regulated by photoperiod and Fv FLOWERING LOCUS T1, suggesting that it plays a central role in the photoperiodic control of both generative and vegetative growth in strawberry. In conclusion, we propose that Fv SOC1 is a signaling hub that regulates yearly cycles of vegetative and generative development through separate genetic pathways.

“…Although PmDAMs were identified as candidates for bud dormancy regulation in Japanese apricot, many other genes, proteins, and metabolites are likely to be involved in this trait. For example, the association of a SOC1-like MADS-box gene with chilling requirements was recently found in apricot (Trainin et al, 2013), and European plum (P. domestica) trees overexpressing poplar FT1 have a reduced chilling requirement for bud break (Srinivasan et al, 2012). There is accumulating evidence of the possible involvement of MADS-box genes and other flowering-related genes in dormancy regulation (Horvath, 2009).…”

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.
