Especially weakly expressed, fruiting body-specific genes would most likely not be detected as differentially expressed (or at all) in an expression study using only sexual mycelium.
The promoters Ppbec1 and Ppxero2, however, are cold-induced both in Arabidopsis transgenic plants as well as transient expressing fruits, suggesting that the Ppbec1 and Ppxero2 promoters are cold-inducible peach promoters.
ACC oxidases belong to a multigene family and members have been shown to be highly expressed during fruit ripening in climacteric fruits.
Genes responsible for sex expression in cucumber and expressed during fruit development were studied along with their promoter regions.
Three miRNAs, csi-miRN31, csi-miR477a-3p csi-miR477a-3p csi-miR477a-3p to be highly expressed in fruit and probably important regulators of fruit ripening.
Among the 37 TF genes induced in ripe fruit (Cluster A), 25 were exclusively expressed in fruit (Cluster A2, Additional file 17).
PpSUS1, the only studied isoform, is prevalently expressed in fruit compared to leaves and is upregulated during fruit ripening and postharvest storage.
3) What is known about taste receptors in fruit flies, and specifically, which of them are expressed in fruit fly larvae?
Peach has four members of the SEP1-4 clade (PpeMADS19, PpeMADS38, PpeMADS21 and PpeMADS09), most of which were highly expressed in fruit and showed little expression elsewhere.
SlJMJ12, SlJMJ16, SlJMJ5 and SlJMJ13 are particularly expressed in fruit at B10, thus suggesting a role in later processes of fruit and/or embryo/seed development.
Similar metallothioneins to the peach sequence found in our experiment were also expressed during fruit development in apricot and in response to cold stress in apple fruit [ 48].
