Activation tagging of theLEAFY PETIOLEgene affects leaf petiole development inArabidopsis thaliana

Development, 2000
ABSTRACTIn a screen for leaf developmental mutants we have isolated an activator T-DNA-tagged mutant that produces leaves without a petiole. In addition to that leafy petiole phenotype this lettuce (let) mutant shows aberrant inflorescence branching and silique shape. The LEAFY PETIOLE (LEP) gene is located close to the right border of the T-DNA insert

Plant Metabolites Screening Identifies 7‐epi‐10‐Deacetyltaxol Inhibiting Cell Division by Interfering With the Cell Cycle and Microtubule Organization

Advanced Science, EarlyView.
In this study, an efficient screening system is developed for plant metabolites to find a compound, 7‐epi‐10‐deacetyltaxol, inhibits tissue elongation. It suppresses plant growth through brassinosteroid and microtubule pathways. It is later applied to animal cells and human tumor organoids, resulting in similar cell division suppression. These findings

Petiole bending in Detached Leaves of Bryophyllum calycinum: Relevance to Polar Auxin Transport in Petioles

Acta Biologica Cracoviensia s. Botanica, 2018
Petiole bending in detached leaves of Bryophyllum calycinum was intensively investigated in relation to polar auxin transport in petioles. When detached leaves were placed leaf blade face down, clear petiole bending was observed. On the other hand, no petiole bending was found when detached leaves were placed leaf blade face up.

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Acid‐activated water hyacinth (Eichhornia crassipes) from the Nile River for textile wastewater reclamation: A comparative evaluation of anionic and cationic dye adsorption

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Water hyacinth (Eichhornia crassipes) is an extremely invasive aquatic plant with notable environmental and socioeconomic impacts; however, its unique physicochemical properties offer potential for wastewater treatment through adsorption. This study investigates the acid activation of water hyacinth using acetic, sulphuric, hydrochloric, and ...

Auxin effectively induces the formation of the secondary abscission zone in Bryophyllum calycinum Salisb. (Crassulaceae)

Acta Agrobotanica, 2016
We have found that auxin, indole-3-acetic acid (IAA) substantially induces the formation of the secondary abscission zone in stem and petiole explants and in decapitated stem and petiole after excision of blade in intact plants of Bryophyllum calycinum ...

Decoupling environmental suitability from realized recruitment through ontogenetic environmental filtering in a long‐lived Mediterranean palm species

Ecography, EarlyView.
Long‐lived plants facing anthropogenic disturbance often exhibit recruitment failure despite persistent reproductive adults, generating extinction debt masked by longevity. However, whether adult presence reliably reflects environmental suitability for recruitment remains unclear.
