Hypocotyl - Wikipedia
Diagram of Scouler's willow (Salix scouleriana) seed, indicating position of hypocotyl. The hypocotyl (short for "hypocotyledonous stem", [1] meaning "below seed leaf") is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle .

Hypocotyl - an overview | ScienceDirect Topics
The dark-grown hypocotyl is an interesting model to relate the changes in cell wall chemistry to cell wall mechanics and development. The hypocotyl elongation is characterized by distinct phases: a slow-elongation phase up to 48 h post-germination, and a rapid-elongation phase from 48 h onwards [69].
Hypocotyl | plant anatomy | Britannica
In the developing embryo, the hypocotyl is the embryonic axis that bears the seedling leaves (cotyledons). …other four will form the hypocotyl, the part of the embryo between the cotyledons and the primary root (radicle). The hypophysis will give rise to the radicle and the root cap; the cells of the suspensor will degenerate as the embryo matures.
Hypocotyl - (Intro to Botany) - Vocab, Definition, Explanations
The hypocotyl is the part of a seedling that connects the cotyledons (seed leaves) to the root system, serving as a crucial transitional zone during germination and early growth. It plays an essential role in the development of the plant, as it elongates to push the cotyledons above the soil, allowing for better light exposure and photosynthesis.
Hypocotyl - an overview | ScienceDirect Topics
The root/hypocotyl is actually composed of supernumerary cambia, or zones of xylem and phloem tissue, that increase in size during growth. From: Encyclopedia of Food and Health, 2016
Environmental Control of Hypocotyl Elongation - PubMed
The hypocotyl is the embryonic stem connecting the primary root to the cotyledons. Hypocotyl length varies tremendously depending on the conditions. This developmental plasticity and the simplicity of the organ explain its success as a model for growth regulation. Light and temperature are prominent …
The Arabidopsis thaliana hypocotyl, a model to identify and study ...
Mar 16, 2014 · In this review, we provide evidence that the hypocotyl serves as ideal model object to study cell expansion mechanisms and its regulation. We focus on the regulation of hypocotyl development by light and highlight the key modulating proteins in this signaling cascade.
Cellular basis of hypocotyl growth in Arabidopsis thaliana.
The Arabidopsis thaliana hypocotyl is widely used to study the effects of light and plant growth factors on cell elongation. To provide a framework for the molecular-genetic analysis of cell elongation in this organ, here we describe, at the cellular level, its morphology and growth and identify a number of characteristic, developmental ...
Hypocotyl | Journal of Embryology
The hypocotyl is a structure found in some plants that connects the cotyledons (seed leaves) to the root. It is located at the base of the stem and is responsible for anchoring the plant to the ground allowing it to absorb water and nutrients from the soil.
