Transcript levels of kiwifruit genes involved in carbohydrate metabolism. Transcript levels measured during fruit development of four Actinidia deliciosa genotypes: G3, high starch and large fruit (filled squares); G25, low starch and large fruit (open squares); G30, high starch and small fruit (filled circles); and G17, low starch and small fruit (open circles). Gene codes: sucrose synthase, (A–B) SUS1, (C–D) SUSA; sucrose phosphate synthase, (E–F) SPS Family A; vacuolar invertase, (G–H) INV3; neutral invertase, (I–J) INK; ADP-glucose pyrophosphorylase, (K–L) APS1, (M–N) APL2, (O–P) APL4; sucrose non-fermenting related kinase, (Q–R) SnRK1; DOF2 zinc finger transcription factor, (S–T) DOF2; α-amylase, (U–V) AMY2, (W–X) AMY3; β-amylase, (Y–Z) BAM1, (AA–AB) BAM9; monosaccharide transporters, (AC–AD) STP1, (AE–AF) STP14; sucrose transporter, (AG–AH) SUC4; hexokinase, (AI–AJ) HKL1, (AK–AL) HK3; fructokinase, (AM–AN) FK4, (AO–AP) FK6, (AQ–AR) FK8. Values are averages of four technical replicates of the reverse-transcribed RNA sample of six pooled biological replicates ±SEM. Housekeeping gene: protein phosphatase 2A (PP2A). Fruit age is given in days after anthesis (DAA). Data refer to 2009 outer pericarp samples.
