Expression data from rice inflorescences of the sro mutant and wild type

Plant organ primordia develop into final size through accelerated cell proliferation and cell expansion. During the early flower development, the size of plant reproductive organs is precisely regulated by numerous genes influencing either or both of these two processes. SRO, a C2H2 Zinc finger transcription factor orthologous to Arabidopsis SUPERMAN in rice, plays a critical role in regulating the reproductive organ size.We used microarrays to detail the expression of genes that were under the control of SRO during reproductive organ development in rice SRO expression reaches a peak at stage Sp7 (inflorescence length 4-5 mm) when stamen and carpel were initiated in most spikelets. We collected 4-5mm inflorescence of sro and wild type (Japonica variety 9522) in the paddy field, three biological replicates each. Total RNA were extracted using Trizol method and hybridized on Affymetrix microarrays.
