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.

Deep Fluorescence Observation in Rice Shoots via Clearing Technology

2022
The present protocol describes a clearing technique for rice shoots, which are difficult to prepare for internal structural observations owing to the hard, thick, or layered nature of the tissues. This method facilitates continuous and deep fluorescence observations, even in adult rice plants.

Differentiating Immortalized Multipotent Otic Progenitors into Spiral Ganglion Neurons and Evaluating the Differentiation
0 Views •
2025
The video demonstrates the differentiation of immortalized multipotent otic progenitors (iMOPs) into spiral ganglion neurons (SGNs) and immunofluorescence-based confirmation of the differentiation. The iMOPs are plated onto culture substrate-coated coverslips in a neuronal differentiation medium for differentiation into SGNs. The differentiated cells are labeled with antibodies specific for neuronal differentiation markers and analyzed under a microscope to confirm differentiation.

Differential Scanning Calorimetry

Source: Danielle N. Beatty and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Differential scanning calorimetry (DSC) is an important measurement to characterize thermal properties of materials. DSC is used primarily to calculate the amount of heat stored in a material as it heats up (heat capacity) as well as the heat absorbed or released during chemical reactions or phase changes. However, measurement of this heat can also lead to...
FAQs
A relatively high cytokinin-to-auxin balance can redirect competent plant cells toward shoot formation. This hormonal relationship influences cell division and developmental fate rather than simply increasing growth. Adjusting the balance helps tissue-culture researchers favor organogenesis, the formation of organized plant organs, and is therefore central to optimizing regeneration systems for different explants.
Explant competence determines whether cultured cells or tissues can respond to developmental signals that promote shoot formation. Even when environmental conditions and plant growth regulators are favorable, the starting tissue must be capable of acquiring shoot identity. Recognizing this requirement helps researchers interpret variable regeneration outcomes and select tissues suitable for propagation or transformation experiments.
Formation of a shoot apical meristem indicates that differentiation has produced an organized shoot-producing structure rather than uncoordinated cell growth. This meristem supports the subsequent development of stems and leaves, making it important for recovering structurally complete plants. Its appearance therefore provides a meaningful developmental outcome when evaluating cultured tissues.
The outcome depends on the interaction between environmental conditions, plant growth regulators, and the developmental competence of the explant. Changes in these factors can redirect cell division and developmental fate, altering whether shoots form and how effectively organized structures develop. Protocol optimization therefore requires coordinating culture conditions with the hormonal balance appropriate for the tissue being studied.
A typical workflow begins with placing a competent explant under controlled culture conditions, followed by exposure to plant growth regulators that favor shoot organogenesis. Researchers then assess the formation of organized shoots, including stems, leaves, and shoot apical meristems, before pursuing recovery of complete plants. This sequence connects cellular responses to measurable regeneration outcomes.
The technique is useful when researchers need many genetically similar plants, regeneration after genetic transformation, or recovery of complete plants from cultured tissues. It supports clonal micropropagation, crop-improvement studies, conservation efforts, and functional investigations. In each case, successful shoot formation provides an intermediate step between cultured tissue and a regenerated plant.
