Interaction Between Actin and Microtubules During Plant Development
Cytoskeleton, EarlyView.ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

Regulation and Identity of Florigen: Flowering Locus T Moves Center Stage [PDF]
, 2008 The transition from vegetative to reproductive growth is controlled by day length in many plant species. Day length is perceived in leaves and induces a systemic signal, called florigen, that moves through the phloem to the shoot apex.

Plant Meristems: Cytokinins — The Alpha and Omega of the Meristem [PDF]
Current Biology, 2007 Recent studies have revealed important new details of how cytokinin-dependent mechanisms control plant growth. Intriguingly, cytokinins are involved in both maintaining meristems and promoting differentiation.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
Cytoskeleton, EarlyView.ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Non-autonomy of AGAMOUS function in flower development: use of a Cre/loxP method for mosaic analysis in Arabidopsis [PDF]
, 1998 Angiosperms use a multi-layered meristem (typically L1, L2 and L3) to produce primordia that then develop into plant organs, A number of experiments show that communication between the cell layers is important for normal development.

DELLA genes restrict inflorescence meristem function independently of plant height
Nature Plants, 2017 DELLA proteins associate with transcription factors to control plant growth in response to gibberellin1. Semi-dwarf DELLA mutants with improved harvest index and decreased lodging greatly improved global food security during the ‘green revolution’ in the

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Control of flower development in Arabidopsis thaliana by APETALA1 and interacting genes [PDF]
, 1993 Mutations in the APETALA1 gene disturb two phases of flower development, flower meristem specification and floral organ specification. These effects become manifest as a partial conversion of flowers into inflorescence shoots and a disruption of sepal ...

Grass inflorescence architecture and meristem determinacy.
Seminars in Cell and Developmental Biology, 2017 The grass inflorescence is striking not only for its beauty and diversity, but also for its developmental complexity. While models of inflorescence architecture have been proposed in both eudicots and grasses, these are inadequate to fully explain the ...
