“…In our analysis, DEF ( LOC103966740 ) was significantly repressed in parthenocarpic and pollinated ovaries. The class E MADS-box genes are essential for all floral whorls involved in specifying organ identities, and AGL9 is an E class gene 52 , 53 . Our studies exhibited that AGL9 was repressed in parthenocarpic fruits.…”

Phytohormones play crucial roles in fruit set regulation and development. Here, gibberellins (GA4+7), but not GA3, induced pear parthenocarpy. To systematically investigate the changes upon GA4+7 induced pear parthenocarpy, dynamic changes in histology, hormone and transcript levels were observed and identified in unpollinated, pollinated and GA4+7-treated ovaries. Mesocarp cells continued developing in both GA4+7-treated and pollinated ovaries. In unpollinated ovaries, mesocarp cells stopped developing 14 days after anthesis. During fruit set process, GA4+7, but not GA1+3, increased after pollination. Abscisic acid (ABA) accumulation was significantly repressed by GA4+7 or pollination, but under unpollinated conditions, ABA was produced in large quantities. Moreover, indole-3-acetic acid biosynthesis was not induced by GA4+7 or pollination treatments. Details of this GA–auxin–ABA cross-linked gene network were determined by a comparative transcriptome analysis. The indole-3-acetic acid transport-related genes, mainly auxin efflux carrier component genes, were induced in both GA4+7-treated and pollinated ovaries. ABA biosynthetic genes of the 9-cis-epoxycarotenoid dioxygenase family were repressed by GA4+7 and pollination. Moreover, directly related genes in the downstream parthenocarpy network involved in cell division and expansion (upregulated), and MADS-box family genes (downregulated), were also identified. Thus, a model of GA-induced hormonal balance and its effects on parthenocarpy were established.

“…The bias of mutant frequency between stamen and petaloid staminodes hints that they suffered the selective pressures, which were the result of an evolutionary balance between producing pollen and attracting pollination. Several lineages of floral organ identity MADS-box genes have been isolated from Zingiberales to investigate their potential roles in the determination of androecial members [1,3,15,16,34,58,61,71]. Compared with model plant systems, broad expression of B-, C-class genes, on the one hand, has expanded the regulatory potential beyond their initial framework, on the other hand, may not be specific in determining petal and androecial member identity.…”

“…Compared with model plant systems, broad expression of B-, C-class genes, on the one hand, has expanded the regulatory potential beyond their initial framework, on the other hand, may not be specific in determining petal and androecial member identity. Previous studies imply that the AGL6 MADS-box gene is required to specify stamen development, and low expression of AGL6 may promote petaloidy in the androecial whorl [33,34,71]. Most, if not all, floral organ identity genes are dosage-dependent [6,20,[67][68][69]72], and the effects of gene dosage on a range of quantitative trait variation may have driven homeosis to occur through gene duplication and loss events.…”

Background: Interpretation of the floral structure of Zingiberaceae has long concentrated on the relationships of the androecial members. It suggested that labellum is composed of two structures rather than three or five, and glands are interpreted either as gynoecial part or as androecial members. Methods: Serial sections were used to observe the vasculature of normal and two-staminate flowers in Alpinia intermedia 'shengzhen'. Floral diagrams were drawn to interpret the morphological category of the floral organs and the relationships of the androecial members. Androecial vascular bundles were associated with carpellary dorsal bundles (CDBs) and parietal bundles (PBs) in a Zingiberales phylogeny setting using ancestral state reconstruction. Results: Anatomical observations demonstrate that the fertile stamen(s) incorporate parietal bundles both in normal and two-staminate flowers. The three appendages represent the three members of the outer whorl of the androecium, while the labellum represents the inner whorl of the androecium in the two-staminate flower. Reconstruction of the origin of the vascular system in the androecium suggests that the outer whorl of androecium receives its vascular supply from the CDBs, and the inner whorl of androecium receives from the PBs in both the basal banana group and the more derived ginger clade. Conclusions: The present study adds to a growing body of literature suggesting that the anatomy of abnormal flowers may not provide enough evidence for elucidating the relationships of the androecial members, and help us to better understand how the vascular system is constructed during the androecial petaloidy evolution.

“…In this model, A‐class genes determine sepal identity, whereas petal identity is controlled by A‐ and B‐class genes, stamen identity is regulated by B‐ and C‐class genes, and carpel formation is mediated by C‐class genes. In A. thaliana , APETALA1 ( AP1 ) and APETALA2 ( AP2 ) are A‐class genes, PESTILLATA ( PI ) and APETALA3 ( AP3 ) are B‐class genes, AGAMOUS ( AG ) is a C‐class gene, and SEPALLATA1 – 4 ( SEP1 – 4 ) are E‐class genes (Ditta, Pinyopich, Robles, Pelaz, & Yanofsky, ; Favaro et al, ; Goto & Meyerowitz, ; Li et al, ; Pelaz, Ditta, Baumann, Wisman, & Yanofsky, ; Pinyopich et al, ). With the exception of AP2 , all of the ABC model genes belong to the MADS‐box gene family.…”

Lettuce (Lactuca sativa L.) is an important leafy vegetable consumed worldwide. Heat‐induced bolting and flowering greatly limit lettuce production during the summer. Additionally, MADS‐box transcription factors are important for various aspects of plant development and architecture (e.g., flowering and floral patterning). However, there has been no comprehensive study of lettuce MADS‐box family genes. In this study, we identified 82 MADS‐box family genes in lettuce, including 23 type I genes and 59 type II genes. Transcriptome profiling revealed that LsMADS gene expression patterns differ among the various floral stages and organs. Moreover, heat‐responsive cis‐elements were detected in the promoter regions of many LsMADS genes. An in situ hybridization assay of 10 homologs of flower‐patterning genes and a yeast two‐hybrid assay of the encoded proteins revealed that the ABC model is conserved in lettuce. Specifically, the APETALA1 (AP1) homolog in lettuce, LsMADS55, is responsive to heat and is specifically expressed in the inflorescence meristem and pappus bristles. The overexpression of LsMADS55 results in early flowering in Arabidopsis thaliana. Furthermore, we observed that the heat shock factor LsHSFB2A‐1 can bind to the LsMADS55 promoter in lettuce. Therefore, a model was proposed for the LsMADS‐regulated floral organ specification and heat‐induced flowering in lettuce.
