Figure 6: Effects of qWS8/ipa1-2D allele in reaching optimal yield potential.
From: A natural tandem array alleviates epigenetic repression of IPA1 and leads to superior yielding rice
(a) Overall morphology of three genotypes in the NIL population. Scale bar, 20 cm. (b) Panicle morphology of three genotypes. Scale bar, 6 cm. (c) Relative expression of IPA1 in three genotypes, normalized to the rice Actin gene. Values are means±s.d. (n=3). (d–i) Yield related trait performance of three alleles in the Shanghai and Hainan experimental stations, including panicle primary branch number (d), panicle secondary branch number (e), spikelet number per panicle (f), tiller number (g), grain weight (h) and yield per plant (i). The homozygous ipa1-2D and IPA1 alleles are denoted by black and white columns and heterozygous allele is denoted by grey columns respectively. Values are means±s.d. (n=67, 124, 62 in Shanghai and 39, 78, 42 in Hainan for three genotypes). Different letters at top of each column indicate a significant difference among genotypes in the respective locations at P<0.05 determined by Tukey’s HSD test.
