Most molecular studies on this species have been performed based on F. vesca reference genome [32] which is a subgenome of F. × ananassa [71]. Expression of the JA-Ile co-receptor FaCOI1 (Fig 7A) was similar to that previously reported in F. × ananassa cv. Elsanta fruit [72]. In general, FaJAZ genes displayed a constant reduction pattern from flowering to ripe fruits, and some genes like FaJAZ1, FaJAZ5 and FaJAZ8.1 showed a pronounced reduction at ripe stages (Fig 7A), according to proanthocyanidins (PAs) reduction and opposite to anthocyanin accumulation during fruit development and ripening of cv. Aromas (S4 Fig). On the other hand, FaJAZ10 was not detected in full ripe fruit (Fig 7A). Recently, similar expression profiles for JAZ genes were reported for a JAZ gene from large green to partial red fruit stages in F. × ananassa cv. Hongyan [31]. In this sense, Sánchez-Sevilla et al. also reported expression reduction for the most JAZ, named like TIFY genes, from RNAseq experiments in achene and receptacle during strawberry (F. × ananassa cv. Camarosa) fruit development and ripening (Panel A in S6 Fig and S10 Table) [73]. Moreover, FaMYC2 and FaMYC2-like genes exhibiting an expression reduction from flowering to ripe stages, similar to that observed for FaJAZs (Fig 7A) and to that previously reported both in achene and receptacle (Panel A in S6 Fig and S10 Table) [73]. MYC2-like genes have been reported in tomato and grape, although their expression patterns in fruit stages are unknown [54,74]. Globally, downregulation of FaJAZs and FaMYC2 genes (Fig 7A) matches with previously reported JA-Ile endogenous levels and expression of JA metabolism-related genes during F. × ananassa fruit development and ripening [7]. This suggests that JA metabolism and signalling are in coordination and JA pathway could have a key role in anthesis and physiological events like PAs biosynthesis that occur during early fruit development in strawberry (S4 Fig).","divisions":[{"label":"Title","span":{"begin":0,"end":100}}],"tracks":[{"project":"2_test","denotations":[{"id":"29746533-21186353-90904163","span":{"begin":396,"end":398},"obj":"21186353"},{"id":"29746533-26835888-90904164","span":{"begin":439,"end":441},"obj":"26835888"},{"id":"29746533-25046752-90904165","span":{"begin":573,"end":575},"obj":"25046752"},{"id":"29746533-28195221-90904166","span":{"begin":1154,"end":1156},"obj":"28195221"},{"id":"29746533-29062051-90904167","span":{"begin":1435,"end":1437},"obj":"29062051"},{"id":"29746533-29062051-90904168","span":{"begin":1687,"end":1689},"obj":"29062051"},{"id":"29746533-24483714-90904169","span":{"begin":1812,"end":1814},"obj":"24483714"},{"id":"29746533-28693415-90904170","span":{"begin":1815,"end":1817},"obj":"28693415"}],"attributes":[{"subj":"29746533-21186353-90904163","pred":"source","obj":"2_test"},{"subj":"29746533-26835888-90904164","pred":"source","obj":"2_test"},{"subj":"29746533-25046752-90904165","pred":"source","obj":"2_test"},{"subj":"29746533-28195221-90904166","pred":"source","obj":"2_test"},{"subj":"29746533-29062051-90904167","pred":"source","obj":"2_test"},{"subj":"29746533-29062051-90904168","pred":"source","obj":"2_test"},{"subj":"29746533-24483714-90904169","pred":"source","obj":"2_test"},{"subj":"29746533-28693415-90904170","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93eccc","default":true}]}]}}
