Flue gas from power plants is a cheap CO2 source for algal growth. We have built prototype "flue gas to algal cultivation" systems and described how to scale up the algal cultivation process. We have demonstrated the use of a mass-transfer bio-reaction model to simulate and to design the optimal operation of flue gas for the growth of Chlorella sp. in algal photo-bioreactors.

Evaluating Motor Impairment in C. elegans Models Using the Radial Locomotion Assay

This video demonstrates the use of a radial locomotion assay to evaluate motor dysfunction in C. elegans expressing either wild-type or ALS-mutant human TDP-43 protein. Worms with varying levels of wild-type or mutant TDP-43 expression are allowed to crawl, and their movement is measured by the radial distance traveled from the central point on the assay plate. The assay distinguishes between mild, moderate, and severe motor impairments based on the distance traveled by the different C. elegans...

Promoter expression analyses are crucial to improving the understanding of gene regulation and the spatiotemporal expression of target genes. Herein we present a protocol to identify, isolate, and clone a plant promoter. Further, we describe the characterization of the nodule-specific promoter in the common bean hairy roots.

Radial System Protection

Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system. In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

The Eukaryotic Promoter Region

The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences. The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

The vascular cambium drives thickening by dividing and producing secondary xylem toward the inside and secondary phloem toward the outside. This activity increases the amount of conducting tissue and contributes to the structural development of stems and roots. Changes in cambial activity therefore influence both plant support and the movement of water and nutrients.
Hormone signals regulate the rate and direction of cambial activity, influencing how strongly tissues expand in width and where growth is concentrated. Their effects operate alongside nutrient availability and environmental conditions rather than independently. Studying these signals helps explain why plants may show different patterns of thickening during development or under changing conditions.
Nutrient availability and environmental conditions can alter the activity of tissues responsible for secondary growth. When these factors change, the rate or direction of radial expansion may also change, affecting stem strengthening, protective tissue development, and transport-related functions. This makes environmental context essential when interpreting differences in plant girth or growth responses.
The cork cambium produces protective tissues as radial development proceeds. These tissues complement the conducting tissues formed by the vascular cambium and help explain how thickening affects more than internal transport. Considering both cambial systems provides a broader view of plant development, including structural reinforcement and protection as stems or roots increase in width.
Researchers can evaluate radial growth promotion by measuring changes in stem or root diameter. Comparing diameter changes across plants, developmental conditions, or treatments provides an outcome measure for the rate of thickening. This approach is useful in experiments that examine growth-promoting treatments and in studies connecting increased girth with plant development or stress responses.
In forestry, changes in radial growth can support management decisions by indicating patterns of stem development and strengthening. In crop improvement, diameter responses can help evaluate traits or treatments associated with plant development. More broadly, the measurement of girth links experimental observations to water and nutrient transport, structural performance, and responses to environmental stress.
