Reproductive effort assessment for woody plants using Siberian spruce and Siberian fir [PDF]

open access: yesE3S Web of Conferences, 2023
The correlation between the yield of Siberian spruce (Picea obovata Ledeb.) and Siberian fir (Abies sibirica Ledeb.) cones and radial wood increments was examined using long-term data (47 years) from direct observations.

Increase in Growth Cone Size Correlates with Decrease in Neurite Growth Rate

open access: yesNeural Plasticity, 2016
Several important discoveries in growth cone cell biology were made possible by the use of growth cones derived from cultured Aplysia bag cell neurons, including the characterization of the organization and dynamics of the cytoskeleton.

A Method to Culture GABAergic Interneurons Derived from the Medial Ganglionic Eminence

open access: yesFrontiers in Cellular Neuroscience, 2018
Understanding the mechanisms guiding interneuron development is a central aspect of the current research on cortical/hippocampal interneurons, which is highly relevant to brain function and pathology.

Relationship among altitude, growth characteristics and cone production in Brutian pine (Pinus brutia Ten.)

open access: yesTurkish Journal of Forestry, 2021
In this study, cone production, altitude and growth characteristics (height, diameter at breast height and crown diameter) were related, and also some genetics parameters were estimated.

Neuronal Growth Cone Size-Dependent and -Independent Parameters of Microtubule Polymerization

open access: yesFrontiers in Cellular Neuroscience, 2018
Migration and pathfinding of neuronal growth cones during neurite extension is critically dependent on dynamic microtubules. In this study we sought to determine, which aspects of microtubule polymerization relate to growth cone morphology and migratory ...

Mechanisms of growth cone repulsion [PDF]

open access: yesF1000 Biology Reports, 2010
Research conducted in the last century suggested that chemoattractants guide cells or their processes to appropriate locations during development. Today, we know that many of the molecules involved in cellular guidance can act as chemorepellents that prevent migration into inappropriate territories. Here, we review some of the early seminal experiments

Actin dynamics in growth cones [PDF]

open access: yesThe Journal of Neuroscience, 1991
The mechanism of actin incorporation and turnover in the nerve growth cone was examined by immunoelectron microscopy and low-light-level video microscopy of cultured neurons injected with biotin-labeled actin or fluorescently labeled actin. We first determined the sites of actin incorporation into the cytoskeleton of growth cones by immunoelectron ...

Directing growth cones of optic axons growing with laser scissors and laser tweezers [PDF]

open access: yes, 2012
We have combined a laser scissors and a laser tweezers to study, (1) the response of nerve fiber growth cones to laserinduced damage on single axons, and (2) localized microfluidic flow generated by laser-driven spinning birefringent particles.
