Snapdragon () serves as a model system for dissecting floral morphogenesis mechanisms. Petal malformation in impacts ornamental value, but its genetic basis remains poorly understood. We compared transcriptomes of the wild-type (Am11) and a petal-malformed mutant (AmDP2) to identify 2303 differentially expressed genes (DEGs), including E-class MIKC-type MADS-box genes () and (). Weighted gene co-expression network (WGCNA), protein-protein interaction (PPI), qRT-PCR and virus-induced gene silencing (VIGS) analyses revealed interactions between SEP2/SEP3 and C/A/B-class genes (, , ), co-regulated MADS transcription factors (MTFs) AGL15 (AmMADS16), and auxin signaling genes (, ). qRT-PCR validated upregulation of and downregulation of in AmDP2. Our results suggest that E-class MADS-box genes are associated with petal malformation through coordinated interactions with hormonal pathways. These findings provide candidate targets for further functional studies in snapdragon.

Purpose: Fetal nucleated red blood cells (fNRBCs) in the peripheral blood of pregnant women contain comprehensive fetal genetic information, making them an ideal target for non-invasive prenatal diagnosis (NIPD). However, challenges in identifying, enriching, and detecting fNRBCs limit their diagnostic potential.
Methods: To overcome these obstacles, we developed a novel biomimetic chip, replicating the micro-nano structure of red rose petals on polydimethylsiloxane (PDMS).

The ARF gene family plays a vital role in regulating multiple aspects of plant growth and development. However, detailed research on the role of the ARF family in regulating flower development in petunia and other plants remains limited. This study investigates the distinct roles of and in flower development.

Background: Touch interventions such as massage and skin-to-skin contact relieve neonatal pain. The Parental touch trial (Petal) aimed to assess whether parental stroking of their baby before a clinically required heel lance, at a speed of approximately 3 cm/s to optimally activate C-tactile nerve fibres, provides effective pain relief.
Methods: Petal is a multicentre, randomised, parallel-group interventional superiority trial conducted in the John Radcliffe Hospital (Oxford University Hospitals NHS Foundation Trust, Oxford, UK) and the Royal Devon and Exeter Hospital (Royal Devon University Healthcare NHS Foundation Trust, Exeter, UK).
