Article Abstract
Tendrils of climbing plants coil along their length, thus forming a striking helical spring and generating tensional forces. It is found that, for tendrils of the passion flower Passiflora caerulea, the generated force lies in the range of 6-140 mN, which is sufficient to lash the plant tightly to its substrate. Further, it is revealed that the generated force strongly correlates with the water status of the plant. Based on a combination of in situ force measurements with anatomical investigations and dehydration-rehydration experiments on both entire tendril segments and isolated lignified tissues, a two-phasic mechanism for spring formation is proposed. First, during the free coiling phase, the center of the tendril begins to lignify unilaterally. At this stage, both the generated tension and the stability of the form of the spring still depend on turgor pressure. The unilateral contraction of a bilayer as being the possible driving force for the tendril coiling motion is discussed. Second, in a stabilization phase, the entire center of the coiled tendril lignifies, stiffening the spring and securing its function irrespective of its hydration status.

Article Synopsis
- There is currently no existing research on the L. plant species found in Bulgaria, prompting this study to analyze its leaves and pulp for metabolic, elemental, and bioactive properties.
- The pulp was rich in fructose and amino acids, while both leaves and pulp contained various essential fatty acids and minerals, with potassium and magnesium being most abundant.
- The study found that leaf extracts demonstrated superior antioxidant and anti-inflammatory effects, as well as notable antibacterial activity, suggesting potential uses in nutritional and cosmetic products.

Callogenesis is one of the most powerful biotechnological approaches for in vitro secondary metabolite production and indirect organogenesis in Passiflora caerulea. Comprehensive knowledge of callogenesis and optimized protocol can be obtained by the application of a combination of machine learning (ML) and optimization algorithms. In the present investigation, the callogenesis responses (i.

Postharvest diseases seriously restrict developments in the passion fruit industry. In this study, we aimed to identify the postharvest pathogen affecting passion fruit, investigate its pathogenicity, and explore relevant control methods. The pathogen was isolated from rotting passion fruit and identified using morphological characteristics, ITS sequences, and phylogenetic tree analyses.

How has urbanization altered the relationships between species and selection on phenotypes? To address this question, Palacio and Ordano measured trait and frugivore selection in blue passionflower (Passiflora caerulea) in three different localities. Their analysis revealed changes in avian selection with urbanization, which altered population phenotypes.
