Bird pollination in three species of Phlogacanthus and its broader implications for bird-flower interactions in Asia.

PREMISE: Our knowledge of bird-flower interactions in Asia is limited. Here, we investigated the pollination ecology of three Phlogacanthus species that differ substantially in floral tube length. The floral tubes of bird-pollinated flowers may either correspond to the bill length of the primary bird pollinator, or relatively short-tubed flowers may be pollinated by both short- and relatively long-billed birds. The pollination systems of the three Phlogacanthus species may differ in traits other than floral tube length, reflecting their association with different bird groups. METHODS: We obse…

The role of MYB21 in jasmonate-mediated processes in Arabidopsis: transcending flower-specific functions to vegetative tissue.

Jasmonic acid (JA) and its derivatives are lipid-derived phytohormones that coordinate plant growth, development, and stress responses through the bioactive conjugate jasmonoyl-isoleucine (JA-Ile). Their role in reproductive development is well established, particularly in stamen maturation through the R2R3-MYB transcription factor MYB21, which has been considered largely flower-specific. Here, we reveal a previously unrecognized role of MYB21 in vegetative tissues of Arabidopsis thaliana. Although basal MYB21 transcript levels in leaves are extremely low and spatially restricted, wounding and

AMCD: A multi-domain agricultural crop and flower image dataset for deep learning-based classification.

Postharvest life of cut narcissus in depth: differences of flower tissues longevity and stem structure anatomy.

BACKGROUND: Despite extensive research on extending the vase life of narcissus, the internal mechanisms-particularly the physiological, biochemical, and anatomical traits-that govern its postharvest longevity remain insufficiently understood. This study examined ten Iranian narcissus populations grown under uniform greenhouse conditions to identify floral and stem traits associated with variation in vase life. Longevity was measured separately for inflorescences, petals, and coronas, while biochemical and physiological attributes were compared between petal and corona tissues and structural ch

Valorization of banana flower waste for biopolymer coatings to enhance post-harvest quality of black grapes.

Banana is one of the most consumed fruits globally, but only a part of it is consumed and the rest of the plant is disposed of which generates a large amount of waste. This paper focuses on how banana waste (Banana flowers) can be utilized for the isolation of cellulose. The effective isolation of cellulose from banana flowers is examined in this work as a potential sustainable and profitable source. The cellulose extraction from banana flowers was done using combination of solvent extraction, alkali treatment and bleaching and the yield obtained from the banana flower was 58.37 ± 0.03% (w/w).…

NtAGL6 of Narcissus tazetta var. chinensis Promotes Flowering via an Indirect Activation Pathway of FT.

Narcissus tazetta var. chinensis is a monocot with unique floral morphology and heat-induced flowering. In Arabidopsis, the MADS-box gene AGL6 promotes flowering by positively regulating FT expression, but whether this regulatory mechanism is conserved in monocots remains unknown. Here, we cloned the AGL6 homolog NtAGL6 from N. tazetta var. chinensis, analyzed its sequence, phylogeny, expression pattern, and promoter cis-elements, and performed ectopic expression in wild-type and ap1 mutant Arabidopsis. Yeast one-hybrid and transient expression assays were used to test its interaction with the

A cis-regulatory allele of ZmNPR1I spatially uncouples flowering from stalk-rot resistance in maize.

Pleiotropic effects of adaptive genes frequently constrain crop improvement by coupling beneficial traits with unfavorable trade-offs. In maize, ZmCCT10 confers strong stalk-rot resistance but causes delayed flowering under long-day conditions, limiting its deployment in temperate breeding. Here, we identify qPss3 as a cis-regulatory locus that governs its downstream target gene, ZmNPR1I. The ZmNPR1I protein represses ZmCCT10 transcription and, together with ZmNPR1-3, facilitates ZmCCT10 protein degradation. The favorable qPss3A5 allele reduces ZmNPR1I expression in leaves, relieving repressio

Ginkgo biloba Flower Extract Accelerates the Wound Healing in Diabetic Rats by Inhibiting Inflammation and Ferroptosis.

Diabetic wounds are a common complication of diabetes mellitus (DM), with healing often impaired by ferroptosis and persistent inflammation. This study investigated the effects of Ginkgo biloba flower extract (GBF) on diabetic wound healing by focusing on inflammation and ferroptosis. Chemical composition analysis identified 123 compounds in GBF containing 73 active ingredients of flavonoids and 12 terpenoids. In vivo, GBF treatment significantly accelerated the wound healing process in diabetic rats, and GBF promoted epithelial regeneration and collagen deposition by increasing the expression

Sustainable Starch-Based Biofilms Incorporated with Waste Hibiscus Flower Extract for Food-Packaging Applications.

The rapid increase in global demand for plastics has raised serious environmental and health concerns due to their nonbiodegradability and greenhouse gas (GHG) emissions. As a result, to mitigate these issues associated with traditional plastics, bioplastics emerge as a sustainable and promising solution. Therefore, the present study aims to develop starch-based bioplastic films incorporated with wasteHibiscus rosa-sinensis (China rose) flower extract (HFE) for sustainable food-packaging applications.

Biosynthesis of Copper Nanoparticles Using Passiflora Flower Extract and Study Their Antimicrobial, Antioxidant And Anticancer Activity.

OBJECTIVE: Copper nanoparticles (CuNPs) have received interest due to their antibacterial, antioxidant, and anticancer effects. However, current synthesis methods frequently use harmful substances. Green synthesis with plant extracts provides a safer, more environmentally friendly option. This study looks at the production of CuNPs with Passiflora flower extract and assesses their biological activity. METHODS: Passiflora extract was used as a reducing and stabilizing agent in the synthesis of CuNPs. UV-Vis spectroscopy, FTIR, SEM, XRD, and AFM were used to characterize the samples. The biolog

miR156-SPLs module regulates flowering and controls plant height by modulating gibberellin biosynthesis in citrus.

Plant height and optimal flowering time are key determinants of crop yield and economic value. However, the regulatory mechanisms governing these traits, particularly in woody plants, remain unclear. In this study, overexpression of a citrus microRNA156 (miR156) family member, Ci-miR156c, resulted in significant phenotypic changes in citrus, including reduced plant height and delayed flowering. miR156-mediated repression of SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE (SPL) genes is a highly conserved regulatory mechanism in plants. Yeast one-hybrid and dual-luciferase assays, along with other relat

Characterizing drought-resilient cotton genotypes through morpho-physiological and biochemical traits at flowering stage.

Drought is a major abiotic stressor significantly reducing global crop productivity by disrupting key morpho-physiological and biochemical processes, including stomatal conductance, photosynthetic efficiency, and water use dynamics. This study systematically assessed the effects of water scarcity on fifty genetically diverse cotton genotypes under three different conditions: normal field capacity (100% FC, monitored by soil moisture weight), moderate drought stress (60% FC), and severe drought stress (40% FC) during the flowering stage, a critical period for crop yield. Key morphological (shoo

Flower-like Fe3S4 nanozymes with peroxidase-like activity for sensitive colorimetric immunodetection of carcinoembryonic antigen.

Flower-like Fe3S4 nanosheets were synthesized via a one-step solvothermal method and employed as peroxidase-mimicking nanozymes in a colorimetric immunoassay for the sensitive detection of carcinoembryonic antigen (CEA). Comprehensive structural and chemical characterizations confirmed the successful synthesis and surface modification of the Fe3S4 nanosheets, enabling efficient antibody conjugation. The nanozymes demonstrated significant peroxidase-mimicking behavior by facilitating the hydrogen peroxide (H2O2)-mediated oxidation of 3,3',5,5'-tetramethylbenzidine (TMB), where hydroxyl radicals
