“…It is interesting to note that Nipponbare, the rice cultivar used in this work, lacks OsC1 function, a R2R3-MYB gene necessary for OsCHS1 expression and anthocyanin production [43]. Thus, our seedlings do not accumulate anthocyanin even in B light, conditions where flavonoid production in cotyledons and leaves is enhanced in Arabidopsis or commonly seen in wild rice varieties [44].…”

Chloroplast-to-nucleus retrograde signalling (RS) is known to impact plant growth and development. In Arabidopsis , we and others have shown that RS affects seedling establishment by inhibiting deetiolation. In the presence of lincomycin, a chloroplast protein synthesis inhibitor that triggers RS, Arabidopsis light-grown seedlings display partial skotomorphogenesis with undeveloped plastids and closed cotyledons. By contrast, RS in monocotyledonous has been much less studied. Here, we show that emerging rice seedlings exposed to lincomycin do not accumulate chlorophyll but otherwise remain remarkably unaffected. However, by using high red (R) and blue (B) monochromatic lights in combination with lincomycin, we have uncovered a RS inhibition of length and a reduction in the B light-induced declination of the second leaf. Furthermore, we present data showing that seedlings grown in high B and R light display different non-photochemical quenching capacity. Our findings support the view that excess B and R light impact seedling photomorphogenesis differently to photoprotect and optimize the response to high-light stress. This article is part of the theme issue ‘Retrograde signalling from endosymbiotic organelles'.

Accumulation of anthocyanin is a desirable trait to be selected in rice domestication, but the molecular mechanism of anthocyanin biosynthesis in rice remains largely unknown. In this study, a novel allele of chromogen gene C , OrC1, from Oryza rufipongon was cloned and identified as a determinant regulator of anthocyanin biosynthesis. Although OrC1 functions in purple apiculus, leaf sheath and stigma in indica background, it only promotes purple apiculus in japonica . Transcriptome analysis revealed that OrC1 regulates flavonoid biosynthesis pathway and activates a few bHLH and WD40 genes of ternary MYB-bHLH-WD40 complex in indica . Differentially expressed genes and metabolites were found in the indica and japonica backgrounds, indicating that OrC1 activated the anthocyanin biosynthetic genes OsCHI , OsF3H , OsANS , OsINS and OsANR and produced six metabolites independently. Artificial selection and domestication of C1 gene in rice occurred on the coding region in the two subspecies independently. Our results reveal the regulatory system and domestication of C1 , provide new insights into MYB transcript factor involved in anthocyanin biosynthesis, and show the potential of engineering anthocyanin biosynthesis in rice.

“…The high anthocyanin content of many crops results from the increased expression of bHLH transcription factors [10]. WD40 is an ancient and highly conserved family of proteins that is involved in myriad plant cellular processes, such as transcriptional regulation, cell division, vesicle formation and transport, processing, signal transduction and so on [21].…”

Background：‘Yujin 2’ is new variety of Lonicera japonica Thunb and its flower color can change from red to yellow; hence, it is a good model for investigating flower color development mechanisms. Results：High throughput transcriptome sequencing of seven flower development stages of Yujin No.2 was carried out, and 133,487 unigenes were annotated, among which 73,088 were differentially expressed. Then the real-time PCR analysis was carried out. Further, the number of up-regulated DEGs was higher than those that were down-regulated. Of these annotated DEGs, plant hormone signal transduction, phenylpropanoid biosynthesis, and flavonoid biosynthesis were active throughout the flowering process during each stage, whereas carotenoid biosynthesis was inactive in the S1-6 stages. Furthermore, phenylalanine synthesis was enhanced in the S1 phase; however, anthocyanin synthesis was weakened in the S5 and S6 phases, which may be consistent with the changes in petal color of ‘Yujin 2’ from red (S1) to white (S5) and gold (S6). The results showed that 114 unigenes were associated with anthocyanin metabolism, and 72 were significantly upregulated or downregulated. According to the analysis of TFs in anthocyanin metabolism, we obtained 47 transcription factors, which belonged to 18 families. The LjDFR, LjABCB1, LjMYC6, LjDDB2, and LjANS genes rapidly increased during the first three stages. However, only LjF3'5'H expression was significantly down-regulated at S5, which was consistent with anthocyanin accumulation. Conclusions：This study developed a transcriptome profile of flower color generation for L. japonica as well as annotated unigene sets of seven anthesis phases, thereby providing possibilities for improving the germplasm of L. japonica with genetic engineering technologies and cultivating new varieties of different colors.
