Summary
Cotton
Area of Science:
- Plant biology
- Molecular biology
- Agricultural science
Background:
- The circadian clock regulates physiological processes.
- Its role in crop root immunity against soil pathogens is unclear.
Purpose of the Study:
- Investigate the cotton circadian clock's role in resistance to Verticillium dahliae.
- Understand the mechanisms linking the clock, microbiome, and immunity.
Main Methods:
- Studied cotton's response to Verticillium dahliae.
- Analyzed rhizosphere microbiome composition.
- Investigated jasmonic acid (JA)-dependent signaling pathways.
- Identified GhLUX as a key regulator.
Main Results:
- Cotton's circadian clock enhances nighttime resistance to Verticillium dahliae.
- The clock shapes the rhizosphere microbiome and activates JA signaling.
- GhLUX represses GhJAZ, amplifying nighttime JA signaling.
- Overexpressing GhLUX improved disease resistance and cotton yield.
Conclusions:
- The circadian clock, rhizosphere microbiota, and root immunity are mechanistically linked in cotton.
- Circadian regulators can enhance disease resistance and crop performance.

02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

02:45Biological Clocks and Seasonal Responses
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
02:50Transgenic Plants
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

02:43Plant Cell Wall
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.Collenchyma and sclerenchyma cells, on the other hand, mainly occur in the outer layers of a plant's stems and leaves. These cells provide the plant with strength and support by either partially thickening their primary cell wall (i.e., collenchyma), or depositing a...
01:17Gene Regulation During Sporulation
Sporulation is a complex developmental process that allows certain Gram-positive bacteria, such as Bacillus subtilis and Clostridium species, to survive extreme environmental conditions. This process is tightly regulated by a series of signaling cascades and transcriptional controls, ensuring the formation of a highly resistant endospore.Sporulation is triggered by unfavorable conditions, such as nutrient depletion, and is governed by a phosphorelay system. One of the sensor kinases, such as...
