Primary and Secondary Growth in Roots and Shoots

2026
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.Primary and secondary growth can occur simultaneously in a plant. While primary growth occurs in newer plant regions, secondary growth transpires in regions that have completed primary growth. There are overlaps and distinctions between root growth and shoot growth.

Establishing a Primary Dorsal Root Ganglia Cell Culture from a Rat Spinal Column

2025
This video demonstrates a technique for isolating and culturing dorsal root ganglia (DRG) cells from the rat spinal column. DRGs excised from the spinal column are treated with enzymes and mechanically dissociated to obtain a single-cell suspension. The cells are cultured in a medium containing inhibitors and growth factors that limit glial cell proliferation and promote neuronal growth, respectively.

Characterizing root system traits is one of the areas of research that is still in its infancy, particularly in sugarcane. Integrating multiple approaches to precisely phenotype sugarcane roots leads to comprehensive and holistic results, enabling the utilization of identified traits and mechanisms for conventional and molecular breeding.

Dorsal root ganglia (DRG) primary cultures are frequently used to study physiological functions or pathology-related events in sensory neurons. Here, we demonstrate the use of lumbar DRG cultures to detect the release of neurotransmitters after neuropeptide FF receptor type 2 stimulation with a selective agonist.

Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative options.
FAQs
Length changes through a coordinated sequence in the root tip. Cells divide in the apical meristem, then grow longer and undergo differentiation behind the root cap. The combined contribution of these regions determines how far the main root extends, making the measurement an indicator of ongoing early development rather than a direct measure of one cellular process.
Water availability, nutrient conditions, hormones, and the surrounding environment can all influence primary root growth. Because these factors affect development, seedlings exposed to different conditions may produce different measurements even during the same early stage. Researchers can therefore use the trait to examine how external conditions interact with internal plant growth regulation.
It provides a measurable growth outcome for testing responses to drought, salinity, or toxic compounds. Comparing measurements across conditions allows researchers to identify whether these stresses are associated with altered early root development. This makes the trait useful in plant physiology and related studies where stress effects must be connected to a visible developmental response.
Measure the distance from the root–shoot junction to the tip of the main root. Applying the same anatomical endpoints across seedlings creates a direct quantitative comparison. This simple procedure can be used during seedling studies to evaluate early development, germination-related responses, or differences produced by environmental treatments.
Seedling measurements provide a growth-based readout that complements observations of germination and developmental progression. Researchers can examine Primary Root Length across seedlings or conditions to assess how early root establishment responds to the factors being studied. The resulting data help connect initial seedling performance with developmental responses without relying only on visual descriptions.
The measurement supports research in plant physiology, genetics, ecology, and agricultural performance. In physiology, it can be related to environmental or hormonal effects; in genetics, it can help characterize developmental differences; and in ecology or agriculture, it can contribute to evaluating responses relevant to growing conditions and early plant performance.
