results:
AOC control looks fine, only transcripts in roots seem underrepresented → use different internal standard → b-actin
AC138130_5 PCR failed → repeat, if fails again make new primers
AC175828_16 looks fine, expressed everywhere, somewhat weaker in roots and leaves, but second band in petioles and roots → maybe homologs not known from draft sequence → (i) increase Ta or (ii) make new primers
AC148405_5 looks bad, smaller band seems to have the correct size → make new primers
AC158504_5 looks fine, weakest expression in roots (but might be due to lower amount of cDNA, see 1.)
AC146866_11 looks ok, but two bands (upper band has the correct size → (i) increase Ta or (ii) make new primers
AC152423_24 looks fine, only expressed in petioles and stem → repeat PCR to make sure amplification was fine in the other tissues
