Summary
Plant promoters contain regulatory elements controlling gene expression in response to light. This review covers recent advances in understanding light-regulated transcription and signal transduction pathways.
Area of Science:
- Plant molecular biology
- Gene regulation
- Photosynthesis research
Background:
- Plant promoters possess cis-acting elements that regulate gene expression based on environmental cues.
- Light-responsive genes have regulatory cis-acting elements in their 5' upstream regions.
- Numerous cis-acting elements and trans-acting factors involved in light response have been identified.
Purpose of the Study:
- To review recent advancements in the study of light-regulated transcriptional regulation.
- To summarize findings on signal transduction pathways mediating light responses in plants.
Main Methods:
- Literature review of recent studies on plant gene regulation.
- Analysis of identified cis-acting elements and trans-acting factors.
- Synthesis of information on signal transduction mechanisms.
Main Results:
- Confirmation of cis-acting elements in 5' upstream regions mediating light responses.
- Characterization of various light-responsive cis-acting elements and trans-acting factors.
- Elucidation of signal transduction pathways involved in light-mediated gene expression.
Conclusions:
- Significant progress has been made in understanding light-regulated transcription in plants.
- Further research continues to uncover complex regulatory networks and signaling mechanisms.

28.8K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

01:25Cell Signaling in Plants
6.9K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

02:45Biological Clocks and Seasonal Responses
41.9K
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.

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

02:16Light Acquisition
9.8K
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.

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...
