Phytoplasma-Induced Floral Abnormalities in Catharanthus roseus Are Associated with Phytoplasma Accumulation and Transcript Repression of Floral Organ Identity Genes

open access: yesMolecular Plant-Microbe Interactions, 2011
Floral symptoms caused by phytoplasma largely resemble floral reversion in other plants. Periwinkle leaf yellowing (PLY) phytoplasma and peanut witches'-broom (PnWB) phytoplasma caused different degrees of floral abnormalities on infected periwinkle ...

Heterochronic developmental shifts underlie floral diversity within Jaltomata (Solanaceae)

open access: yesEvoDevo, 2017
Background Heterochronic shifts during mid- to late stages of organismal development have been proposed as key mechanisms generating phenotypic diversity.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

A novel allele of FILAMENTOUS FLOWER reveals new insights on the link between inflorescence and floral meristem organization and flower morphogenesis

open access: yesBMC Plant Biology, 2010
Background The Arabidopsis FILAMENTOUS FLOWER (FIL) gene encodes a YABBY (YAB) family putative transcription factor that has been implicated in specifying abaxial cell identities and thus regulating organ polarity of lateral organs. In contrast to double

Floral induction, floral hormones and flowering [PDF]

open access: yes, 1972
The factors, influencing the synthesis and action of floral hormones, and possible differences between floral hormones in different plants were studied.

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

MADS on the move : a study on MADS domain protein function and movement during floral development in Arabidopsis thaliana [PDF]

open access: yes, 2010
In this thesis we investigated the behaviour of fluorescently-tagged MADS domain proteins during floral development in the model plant Arabidopsis thaliana, and explored the importance of intercellular transport via plasmodesmata for MADS domain ...

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

open access: yesAdvanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Spatio-Temporal Dynamics of the Patterning of Arabidopsis Flower Meristem

open access: yesFrontiers in Plant Science, 2021
The qualitative model presented in this work recovers the onset of the four fields that correspond to those of each floral organ whorl of Arabidopsis flower, suggesting a mechanism for the generation of the positional information required for the ...
