Cell Signaling in Plants

Cell Signaling in Plants

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...

Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

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.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Role of Skin in Vitamin D Synthesis

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

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.

Defenses Against Pathogens and Herbivores

Defenses Against Pathogens and Herbivores

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Background:

Vitamin E (tocochromanols) is a crucial lipid-soluble antioxidant produced by photosynthetic organisms.
It plays essential roles in human nutrition and plant adaptation to environmental stresses.
The initial step in tocochromanol synthesis involves incorporating prenyl groups with homogentisate.

Purpose of the Study:

To provide an updated overview of the tocochromanol biosynthesis pathway.
To elucidate the mystery of chlorophyll-derived prenyl precursors.
To discuss the role of Vitamin E in plant stress responses and its potential as signaling molecules.

Main Methods:

Review of recent advances in Vitamin E research.
Summary of findings from forward genetic screening.
Integration of genome-wide association studies.

Main Results:

Significant progress has been made in understanding Vitamin E biosynthesis.
The complete roadmap for tocochromanol biosynthesis is now largely revealed.
Key insights into chlorophyll-derived prenyl precursors have been acquired.

Conclusions:

The review presents the most current understanding of the Vitamin E biosynthesis pathway.
Vitamin E is critical for plant adaptation and stress response.
Further research into Vitamin E's signaling functions is warranted.
