Abstract Background: Tree peony (Paeonia suffruticasa) is an economically, medicinally ornamentally important woody flowering woody plants in East Asia and is a common also ornamental shrub in Europe and North America. It is well known and prized for their beautiful flowers in many different forms. Samen petalody has been shown to be the most effective way to modify flower forms. However, there is limited information on the molecular mechanisms of stamen petalody and flower form formation in tree peony.Results: In this study, RNA sequencing was used to assemble and annotate the unigenes in the tree peony to identify the critical genes related to flower parts formation and verify the key genes in different flower forms of tree peony cultivar. A total of 76,007 high quality unigenes were assembled and 30,505 were successfully annotated. A total of 1,833 TFs were identified in our study, among them 16 MADS-box genes were found and characterized. Six key genes were selected to verity their functions in stamen petalody. AG and SEP showed high expression level in carpals and sepals separately both in stamen petalody group and non-stamen petalody groups. PI and AP3 showed high expression levels in inter-petals in stamen petalody groups than in staments in non-stamen petalody.Conclusion: Sixteen MADS-box genes were identified for the first time in tree peony through RNA-seq method. We identified six key genes based on their differential expression levels in different flower parts. These six key genes represented all categories in the ABCDE model to verify the functions in stamen petalody. PI and AP3 were verified to likely play important roles in regulating stamen petalody in tree peony. Our study has helped establish the flower development model in tree peony, identified key molecular mechanisms in the development of different flower forms, and provided valuable information in improving genetic diversity of tree peony and many other woody plants.

Mads Box Gene

MADS-box transcription factors (TFs) have fundamental roles in regulating floral organ formation and flowering time in flowering plants. In order to understand the function of MIKC-type MADS-box family genes in Cyclocarya paliurus (Batal.) Iljinskaja, we first implemented a genome-wide analysis of MIKC-type MADS-box genes in C. paliurus. Here, the phylogenetic relationships, chromosome location, conserved motif, gene structure, promoter region, and gene expression profile were analyzed. The results showed that 45 MIKC-type MADS-box were divided into 14 subfamilies: BS (3), AGL12 (1), AP3-PI (3), MIKC* (3), AGL15 (3), SVP (5), AGL17 (2), AG (3), TM8 (1), AGL6 (2), SEP (5), AP1-FUL (6), SOC1 (7), and FLC (1). The 43 MIKC-type MADS-box genes were distributed unevenly in 14 chromosomes, but two members were mapped on unanchored scaffolds. Gene structures were varied in the same gene family or subfamily, but conserved motifs shared similar distributions and sequences. The element analysis in promoters’ regions revealed that MIKC-type MADS-box family genes were associated with light, phytohormone, and temperature responsiveness, which may play important roles in floral development and differentiation. The expression profile showed that most MIKC-type MADS-box genes were differentially expressed in six tissues (specifically expressed in floral buds), and the expression patterns were also visibly varied in the same subfamily. CpaF1st24796 and CpaF1st23405, belonging to AP3-PI and SEP subfamilies, exhibited the high expression levels in PA-M and PG-F, respectively, indicating their functions in presenting heterodichogamy. We further verified the MIKC-type MADS-box gene expression levels on the basis of transcriptome and qRT-PCR analysis. This study would provide a theoretical basis for classification, cloning, and regulation of flowering mechanism of MIKC-type MADS-box genes in C. paliurus.

Abstract Background: Tree peony ( Paeonia suffruticasa ) is an economically, medicinally and ornamentally important woody flowering plant in East Asia. It is also a common ornamental shrub in Europe and North America. They are well known and prized for their beautiful flowers in many different shapes. Stamen petalody has been shown to be the most effective way to modify flower shapes. However, there is limited information on the molecular mechanisms of stamen petalody and flower shape formation in tree peony. Results: In this study, RNA sequencing was used to assemble and annotate the unigenes in tree peony to identify the critical genes related to flower parts formation and verify the key genes in different flower shapes of tree peony cultivars. A total of 76,007 high quality unigenes were assembled and 30,505 were successfully annotated. A total of 1,833 transcription factors (TFs) were identified in our study, among them 16 MADS-box genes were found and characterized. Six key genes were selected to verify their functions in stamen petalody. AG and SEP showed high expression level in carpels and sepals separately both in stamen petalody and non-stamen petalody groups. PI and AP3 s howed higher expression levels of inter-petals in the stamen petalody group, compared to stamens of non-stamen petalody. Conclusion: S ixteen MADS-box genes were identified in tree peony through RNA-seq. We identified six key genes based on their differential expression levels in different flower parts. These six key genes represented all categories in the ABCDE model to verify the functions in stamen petalody. We speculate that PI and AP3 may trigger the stamen petalody in tree peony. Our study has helped establish the flower development model in tree peony, to identify key molecular mechanisms in the development of different flower shapes, and to provide valuable information for improving the genetic diversity of tree peony and many other woody plants.

BACKGROUND: Black raspberry is a vital fruit crop with a high antioxidant function. MADS-box genes play an important role in the regulation of fruit development in angiosperms. OBJECTIVE: To understand the regulatory role of the MADS-box family, a total of 80 MADS-box genes were identified and analyzed. METHODS: The MADS-box genes in the black raspberry genome were analyzed using bioinformatics methods. Through an analysis of the promoter elements, the possible functions of different members of the family were predicted. The spatiotemporal expression patterns of members of the MADS-box family during black raspberry fruit development and ripening were systematically analyzed. RESULTS: The genes were classified into type I (Mα: 33; Mβ: 6; Mγ: 10) and type II (MIKC *: 2; MIKCC: 29) genes. We also obtained a complete overview of the RoMADS-box gene family through phylogenetic, gene structure, conserved motif, and cis element analyses. The relative expression analysis showed different expression patterns, and most RoMADS-box genes were more highly expressed in fruit than in other tissues of black raspberry. CONCLUSIONS: This finding indicates that the MADS-box gene family is involved in the regulation of fruit ripening processes in black raspberry.
