Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Optimization Problems

Optimization Problems

Optimization problems often involve identifying maximum or minimum values under specific constraints. A well-known example is determining the longest horizontal pipe that can be moved around a right-angled corner, where a 3-meter-wide hallway meets a 2-meter-wide hallway. This scenario, common in architectural design and industrial transport, can be understood conceptually through geometric and trigonometric reasoning.To visualize the problem, consider the pipe as a straight line that touches...

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Scalar Product (Dot Product)

Scalar Product (Dot Product)

The scalar multiplication of two vectors is known as the scalar or dot product. As the name indicates, the scalar product of two vectors results in a number, that is, a scalar quantity. Scalar products are used to define work and energy relations. For example, the work that a force (a vector) performs on an object while causing its displacement (a vector) is defined as a scalar product of the force vector with the displacement vector.
The scalar product of two vectors is obtained by multiplying...

Vector Product (Cross Product)

Vector Product (Cross Product)

Vector multiplication of two vectors yields a vector product, with the magnitude equal to the product of the individual vectors multiplied by the sine of the angle between both the vectors and the direction perpendicular to both the individual vectors. As there are always two directions perpendicular to a given plane, one on each side, the direction of the vector product is governed by the right-hand thumb rule.
Consider the cross product of two vectors. Imagine rotating the first vector about...

Background:

Photorespiration in C3 plants is an inefficient process involving ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and a multi-organellar pathway.
This process consumes energy and reduces crop yields by up to 50%, highlighting the need for improvement.

Purpose of the Study:

To review various strategies for engineering photorespiration in plants to increase crop productivity.
To explore methods aimed at optimizing or reducing the impact of photorespiration on crop yields.

Main Methods:

Review of existing and proposed approaches to engineer photorespiration.
Analysis of strategies including optimizing native pathways, introducing alternative pathways, and reducing Rubisco oxygenation.

Main Results:

Several proposed engineering designs have demonstrated proof-of-concept success.
Plant systems engineering, leveraging synthetic biology and in silico design, shows promise for future advancements.

Conclusions:

Modifying photorespiration presents a significant opportunity to enhance C3 crop productivity.
Integrated approaches combining synthetic biology and computational design are key to developing more productive crops.
