Summary: This study focused on the MADS-box gene family in Prunus campanulata 'Plena' and its role in double-flower formation. The results showed that the double-flower phenotype originated from petaloid stamens. Analysis of MIKC-type MADS-box genes revealed upregulated genes involved in petal development and downregulated genes participating in stamen identity. This research provides a theoretical foundation for understanding the molecular mechanism underlying double flowers in ornamental plants.

Summary: Fruit ripening is regulated by transcription factors, plant hormone ethylene, and DNA methylation. DNA methylation affects fruit ripening by transferring methyl groups. Tomato fruit ripening is dynamically regulated by DNA methylation and demethylation, but the specific molecular mechanism is still unclear.

Summary: This study identified a small regulatory RNA, cja-miR5179, which is exclusively expressed in the ovules of Camellia japonica during early floral development. The miRNA targets a B-class MADS-box gene and its regulation is conserved between Camellia and orchids. The study highlights the evolutionary conservation and functional divergence of small RNAs in floral development.

Summary: In this study, 136 MADS-box genes were identified in the tea plant (Camellia sinensis). The evolutionary relationship, functional characteristics, and expression profiles of these genes were systematically investigated. The expansion of MADS-box genes in the tea plant was mainly contributed by gene duplications, and these genes play important roles in the response to cold stress. Moreover, a floral 'ABCE' model was proposed and confirmed in the tea plant. This study provides valuable insights into the MADS-box genes in the tea plant and lays the foundation for further functional characterizations.

Summary: In this study, 89 MADS-box genes were identified for the first time in the whole genome of C. chekiangoleosa. These genes showed expansion by tandem and fragment duplication and could be divided into type I and type II. Compared to Camellia sinensis and Arabidopsis thaliana, C. chekiangoleosa had a higher proportion of type II genes, suggesting a higher duplication rate or lower loss rate. The type II genes were more conserved and had extra-long amino acid sequences. This study provides important foundation for studying the reproductive organ development of C. chekiangoleosa.

Summary: Lignification of fruit flesh is a common disorder that affects fruit quality during post-harvest storage. In this study, the molecular mechanisms and key genes involved in fruit senescence-induced lignification were investigated in loquat fruit. The results suggest that a senescence-specific MADS-box gene, EjAGL15, functions as a positive regulator of flesh lignification in loquat fruit.

Summary: This study investigated the chromatin occupancy of GATA4 during heart development. The researchers found that GATA4 occupies genomic regions with lineage-specific enhancers in cardiomyocyte and endocardial lineages. They also discovered that non-pioneer transcription factors NKX2-5 and ETS1 guide the activity of GATA4, promoting its binding and opening of chromatin, and regulating endocardial development.

Summary: Photoperiod plays a major role in the development of CH-CL dimorphic flowers in Viola philippica, with only long-day conditions inducing CL flowers. Increased active gibberellin content in CL floral buds under short-day conditions suggests a link between GA biosynthesis and dimorphic flower development, influencing the expression of B-class MADS-box genes in stamen and petal development.

Summary: This study focused on the Rubiaceae plants and identified morpho-anatomical changes during fruit development, distinguishing those derived from the carpel versus the extra-carpellary tissues. Comparative analyses of gene evolution and expression patterns revealed that the Rubiaceae gene complement is simpler compared to Brassicaceae or Solanaceae, and gene expression varies in response to fruit type and developmental stage.

Summary: The developmental regulation of flower organs involves the spatio-temporal regulation of floral homeotic genes. BASIC PENTACYSTEINE genes (BPC genes) are plant-specific transcription factors that play important roles in plant development. In this study, a Class I BPC gene (CjBPC1) from Camellia japonica was characterized. It was found that CjBPC1 is highly expressed in the central whorls of flowers and overexpression of it in Arabidopsis led to severe defects in siliques and seeds. Further analysis revealed that CjBPC1 recruits the Polycomb Repression Complex to suppress the expression of genes involved in ovule and seed development.
