Tissue culture of oil palm : finding the balance between mass propagation and somaclonal variation [PDF]

open access: yes, 2019
The oil palm (Elaeis guineensis Jacq.) is typically propagated in vitro by indirect somatic embryogenesis, a process in which somatic cells of an explant of choice are, via an intermediate phase of callus growth, induced to differentiate into somatic ...

Meristem Maintenance in Maize [PDF]

open access: yesThe Plant Cell, 2015
Stem cells in the shoot meristem are the ultimate source of aerial organs in plants. They shape the plant, determining the layout of branches, leaves, and flowers, and allow plants to produce new organs throughout their life cycle.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Functional Diversification of euANT/PLT Genes in Oryza sativa Panicle Architecture Determination

open access: yesFrontiers in Plant Science, 2021
Grain yield, which is one of the most important traits in rice breeding, is controlled in part by panicle branching patterns. Numerous genes involved in the control of panicle architecture have been identified through mutant and QTL characterization ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal 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

Genetic Analysis of Axillary Meristem Development in Arabidopsis: Roles of MIR164, CUC1, CUC2, CUC3 and LAS, and identification of novel regulators. [PDF]

open access: yes, 2007
Aerial architecture and reproductive success in higher plants is determined by the formation of secondary axes of growth which are formed by axillary meristems initiated post-embryonically in the axils of leaves.

Cadmium and arsenic affect root development in Oryza sativa L. negatively interacting with auxin [PDF]

open access: yes, 2018
Cadmium (Cd) and arsenic (As), non essential, but toxic, elements for animals and plants are frequently present in paddy fields. Oryza sativa L., a staple food for at least the half of world population, easily absorbs As and Cd by the root, and in this ...

Differential spatial distribution of miR165/6 determines variability in plant root anatomy [PDF]

open access: yes, 2017
A clear example of interspecific variation is the number of root cortical layers in plants. The genetic mechanisms underlying this variability are poorly understood, partly due to the lack of a convenient model.

Plant Meristems: Cytokinins — The Alpha and Omega of the Meristem [PDF]

open access: yesCurrent 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.

Mutations in the PERIANTHIA gene of Arabidopsis specifically alter floral organ number and initiation pattern [PDF]

open access: yes, 1996
An open question in developmental biology is how groups of dividing cells can generate specific numbers of segments or organs. We describe the phenotypic effects of mutations in PERIANTHIA, a gene specifically required for floral organ patterning in ...
