Plant Hormones01:56

Plant Hormones

27.6K
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.

Tonicity in Plants00:53

Tonicity in Plants

59.9K
Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.

Plant Cell Wall02:43

Plant Cell Wall

60.5K
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.

Plant Cells and Tissues02:01

Plant Cells and Tissues

65.8K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Summary

Plant epitranscriptomics involves chemical modifications to RNA, like N6-methyladenosine (m6A) and 5-methylcytosine (m5C). These marks regulate key plant biological processes, offering new insights into gene regulation.

Area of Science:

  • Molecular Biology
  • Plant Science
  • Genetics

Background:

  • Ribonucleotides undergo covalent chemical modifications, forming an epitranscriptomic system analogous to the epigenome.
  • This system involves 'writer', 'reader', and 'eraser' proteins that deposit, recognize, and remove RNA marks.
  • These modifications alter RNA structure and binding properties, influencing biological functions.

Purpose of the Study:

  • To review recent advancements in plant epitranscriptomics.
  • To highlight the roles of N6-methyladenosine (m6A) and 5-methylcytosine (m5C) in plants.
  • To provide a nuanced understanding of how epitranscriptomic components regulate plant biology.

Main Methods:

  • Integration of classical biochemical techniques with high-throughput sequencing.
