Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Tonicity in Plants

Tonicity in Plants

Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Wave Parameters

Wave Parameters

The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...

Background:

Image-based high-throughput phenotyping offers advantages over destructive methods in plant science.
Predicting plant biomass is crucial for plant breeders and ecologists.
Developing robust biomass predictive models across diverse experimental conditions remains challenging.

Purpose of the Study:

To develop and validate quantitative models for predicting plant biomass accumulation using image-based features.
To assess the performance of different predictive models, including random forest, for biomass estimation.
To identify key image-based features influencing plant biomass and their contribution.

Main Methods:

Constructed four predictive models to analyze the relationship between image-based features and plant biomass.
Applied the methodology to three consecutive barley (Hordeum vulgare) experiments under control and stress treatments.
Utilized a random forest model for accurate biomass prediction from image data.

Main Results:

Plant biomass was accurately predicted from image-based parameters using the random forest model.
The model demonstrated high prediction accuracy, aiding in overcoming phenotyping bottlenecks for biomass measurement.
Quantified the relative contribution of individual features, providing insights into phenotypic determinants of biomass.
Prediction performance remained relatively high across experiments under similar conditions.

Conclusions:

Developed quantitative models for accurate plant biomass prediction from image data.
Results advance understanding of phenotypic determinants of plant biomass.
The statistical methods are potentially applicable to other plant species.
