Phytohormone biosynthesis and transcriptional analyses provide insight into the main growth stage of male and female cones Pinus koraiensis

open access: yesFrontiers in Plant Science, 2023
The cone is a crucial component of the whole life cycle of gymnosperm and an organ for sexual reproduction of gymnosperms. In Pinus koraiensis, the quantity and development process of male and female cones directly influence seed production, which in ...

Varicones and growth cones: two neurite terminals in PC12 cells. [PDF]

open access: yesPLoS ONE, 2009
The rat adrenal pheochromocytoma PC12 cell line is one of the traditional models for the study of neurite outgrowth and growth cone behavior. To clarify to what extent PC12 neurite terminals can be compared to neuronal growth cones, we have analyzed ...

Growth cone dynamics during the migration of an identified commissural growth cone [PDF]

open access: yesThe Journal of Neuroscience, 1993
We have used time-lapse video microscopy to study the behavior of a neuron, Q1, that pioneers the posterior commissure of the embryonic grasshopper. Our goal is to use time-lapse video as a tool to acquire a precise picture of normal development over time, and thereby identify stereotypic activities that might indicate important interactions necessary ...

Inositol 1,4,5-Trisphosphate Receptor Type 3 Regulates Neuronal Growth Cone Sensitivity to Guidance Signals

open access: yesiScience, 2020
Summary: During neurodevelopment, the growth cone deciphers directional information from extracellular guidance cues presented as shallow concentration gradients via signal amplification.

Commissural Axon Kinetics and the Role of Netrin in Early Brain Circuitry Development [PDF]

open access: yes, 2005
As neurons begin to differentiate, they send out processes called axons to initiate the formation of functional nerve connections. A specialized structure at the end of an axon called the growth cone is believed to possess the impressive navigational and

Non-muscle myosin II regulates neuronal actin dynamics by interacting with guanine nucleotide exchange factors. [PDF]

open access: yesPLoS ONE, 2014
Non-muscle myosin II (NM II) regulates a wide range of cellular functions, including neuronal differentiation, which requires precise spatio-temporal activation of Rho GTPases.
