“…MdMYC2 Enhances the Transcription of MdERF3, Which Positively Regulates the MdACS1 Promoter Previously, we reported that ERF transcription factors regulate the expression of MdACS1 (Li et al, 2016), and in this study, we examined the expression of three ERFs, MdERF1, 2, and 3 (Wang et al, 2007;Li et al, 2016). The expression of MdERF1 and 2 in apple fruit was not affected by MeJA treatment (Figures 4A and 4B), but the expression of MdERF3 was substantially induced by this treatment ( Figure 4C).…”

“…On the whole peach genome, 74 ERF genes were predicted including only one copy of ERF4. Most reported fruit ERFs have been shown to be induced with ripening or ethylene treatment, including plum, apple, tomato and kiwi (Tournier et al, 2003;Wang et al, 2007;El-Sharkawy et al, 2009;Yin et al, 2010). Subfamily VII (comprising ERF4) of ERF genes has been particularly associated with fruit ripening.…”

The present study investigates the genetic determinism of flowering and maturity dates, two traits highly affected by global climate change. Flowering and maturity dates were evaluated on five progenies from three Prunus species, peach, apricot and sweet cherry, during 3-8 years. Quantitative trait locus (QTL) detection was performed separately for each year and also by integrating data from all years together. High heritability estimates were obtained for flowering and maturity dates. Several QTLs for flowering and maturity dates were highly stable, detected each year of evaluation, suggesting that they were not affected by climatic variations. For flowering date, major QTLs were detected on linkage groups (LG) 4 for apricot and sweet cherry and on LG6 for peach. QTLs were identified on LG2, LG3, LG4 and LG7 for the three species. For maturity date, a major QTL was detected on LG4 in the three species. Using the peach genome sequence data, candidate genes underlying the major QTLs on LG4 and LG6 were investigated and key genes were identified. Our results provide a basis for the identification of genes involved in flowering and maturity dates that could be used to develop cultivar ideotypes adapted to future climatic conditions.

In fruit tree orchards, flowering phenology has an indirect influence on spring frost damage, pollination, dormancy and maturity. Even though in a warming scenario, the current risk of frost damage might remain a preoccupation for growers subsequently to advanced flowering time and more irregularities of temperature conditions. Moreover, new risks are emerging as disruptions in floral phenology synchronization, which may disturb pollination for varieties that necessitate cross pollination. In addition, marked changes in the order of flowering time within a varietal range or between adjacent cropping areas may modify the orders of fruit maturity time and consequently disturb commercial specificities.The Prunus genus, within the Rosaceae family, is characterized by species that produce drupes as fruit, and can be divided into three major subgenera: Amygdalus (peach (Prunus persica (L.) Batsch) and almond (Prunus dulcis Mill.)), Prunophora (apricot (Prunus armeniaca L.)), Cerasus (sweet cherry (Prunus avium L.) and sour cherry (Prunus cerasus L.)). All these species are grown in climates with well-differentiated seasons where they have adapted to survive to low winter temperatures and summer drought. In Prunus, as in most woody perennials, the physiology and biochemistry of the flowering

The Role of Ethylene and Cold Temperature in the Regulation of the Apple POLYGALACTURONASE1 Gene and Fruit Softening

et al. 2010

Fruit softening in apple (Malus 3 domestica) is associated with an increase in the ripening hormone ethylene. Here, we show that in cv Royal Gala apples that have the ethylene biosynthetic gene ACC OXIDASE1 suppressed, a cold treatment preconditions the apples to soften independently of added ethylene. When a cold treatment is followed by an ethylene treatment, a more rapid softening occurs than in apples that have not had a cold treatment. Apple fruit softening has been associated with the increase in the expression of cell wall hydrolase genes. One such gene, POLYGALACTURONASE1 (PG1), increases in expression both with ethylene and following a cold treatment. Transcriptional regulation of PG1 through the ethylene pathway is likely to be through an ETHYLENE-INSENSITIVE3-like transcription factor, which increases in expression during apple fruit development and transactivates the PG1 promoter in transient assays in the presence of ethylene. A coldrelated gene that resembles a COLD BINDING FACTOR (CBF) class of gene also transactivates the PG1 promoter. The transactivation by the CBF-like gene is greatly enhanced by the addition of exogenous ethylene. These observations give a possible molecular mechanism for the cold-and ethylene-regulated control of fruit softening and suggest that either these two pathways act independently and synergistically with each other or cold enhances the ethylene response such that background levels of ethylene in the ethylene-suppressed apples is sufficient to induce fruit softening in apples.
