Transgenes designed to overexpress anthocyanin genes An6 (encoding dihydroflavonol-4-reductase) or Hf1 (encoding flavonoid-3′,5′-hydroxylase) in Petunia hybrida L. produced flower colour phenotypes similar to those caused by sense cosuppression of chalcone synthase (Chs) genes. However, unlike Chs, sense cosuppression of An6 and Hf1 resulted in female infertility in transgenotes exhibiting complete phenotypic suppression of anthocyanins. Female sterility appeared to be due to embryo abortion, with discolouration of ovules first appearing about 4 d post-fertilization, followed by gradual collapse of the ovule. Pollen from cosuppressed, female-sterile transgenotes placed on wild-type stigmas produced normal seed set, indicating that sterility of cosuppressed plants was maternally controlled. We suggest an hypothesis that cosuppression of An6 and Hf1 leads to accumulation of dihydroflavonols in the seed coat, a maternal tissue, and that this accumulation inhibits embryo growth, either directly or indirectly. In this hypothesis, direct inhibition of embryo growth would require that dihydroflavonols diffuse from the seed coat into the embryo and act there, whereas indirect inhibition would require that dihydroflavonols interfere with some capacity of the seed coat to promote embryo growth.

The complete chloroplast genome of J. flava, an endangered medicinal plant in Saudi Arabia, was sequenced and compared with cp genome of three Acanthaceae species to characterize the cp genome, identify SSRs, and also detect variation among the cp genomes of the sampled Acanthaceae. NOVOPlasty was used to assemble the complete chloroplast genome from the whole genome data. The cp genome of J. flava was 150, 888bp in length with GC content of 38.2%, and has a quadripartite structure; the genome harbors one pair of inverted repeat (IRa and IRb 25, 500bp each) separated by large single copy (LSC, 82, 995 bp) and small single copy (SSC, 16, 893 bp). There are 132 genes in the genome, which includes 80 protein coding genes, 30 tRNA, and 4 rRNA; 113 are unique while the remaining 19 are duplicated in IR regions. The repeat analysis indicates that the genome contained all types of repeats with palindromic occurring more frequently; the analysis also identified total number of 98 simple sequence repeats (SSR) of which majority are mononucleotides A/T and are found in the intergenic spacer. The comparative analysis with other cp genomes sampled indicated that the inverted repeat regions are conserved than the single copy regions and the noncoding regions show high rate of variation than the coding region. All the genomes have ndhF and ycf1 genes in the border junction of IRb and SSC. Sequence divergence analysis of the protein coding genes showed that seven genes (petB, atpF, psaI, rpl32, rpl16, ycf1, and clpP) are under positive selection. The phylogenetic analysis revealed that Justiceae is sister to Ruellieae. This study reported the first cp genome of the largest genus in Acanthaceae and provided resources for studying genetic diversity of J. flava as well as resolving phylogenetic relationships within the core Acanthaceae.
