Southern Blot02:57

Southern Blot

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
Light Acquisition02:16

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

    Summary

    The southern corn leaf blight epidemic caused significant crop losses. A correction notes that the major loss occurred in 1969, not 1968, impacting agricultural records.

    Area of Science:

    • Agricultural Science
    • Plant Pathology

    Background:

    • Southern corn leaf blight is a significant disease affecting maize crops.
    • Understanding the historical impact of this epidemic is crucial for agricultural planning.

    Purpose of the Study:

    • To provide an accurate historical account of the southern corn leaf blight epidemic.
    • To correct a factual error in the recorded year of major crop loss.

    Main Methods:

    • Review of historical agricultural records.
    • Correction of published data regarding crop loss years.

    Main Results:

    • Identified an error in the reported year of peak crop loss due to southern corn leaf blight.
    • The primary year of significant loss was 1969, not 1968.
