Summary
EPF2 and BASL independently regulate asymmetric cell divisions, controlling stomatal development in Arabidopsis. This research clarifies key molecular mechanisms governing plant epidermal patterning and cell fate determination.
Area of Science:
- Plant biology
- Developmental biology
- Cellular regulation
Background:
- Stomatal development in Arabidopsis epidermis begins with an asymmetric division, forming a meristemoid and a larger cell.
- Meristemoids can divide asymmetrically to self-renew before differentiating into guard mother cells, which then divide symmetrically to form guard cells and a stomatal pore.
Discussion:
- EPF2 (Epidermal Patterning Factor 2) and BASL (Brassinoside- and Stearoyltransferase-Like) are known regulators of asymmetric cell divisions in stomatal development.
- This study investigates the independent roles of EPF2 and BASL in controlling these crucial developmental events.
Key Insights:
- EPF2 and BASL function independently rather than in a shared pathway to control stomatal lineage asymmetric divisions.
- This independent action highlights distinct molecular mechanisms governed by each factor in regulating cell fate and patterning during stomatal formation.
Outlook:
- Further research can elucidate the specific molecular targets and downstream pathways of EPF2 and BASL.
- Understanding these independent regulatory mechanisms could offer insights into optimizing plant epidermal development for agricultural applications.

02:04Regulation of Transpiration by Stomata
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.
02:32Plasmodesmata
The organs in a multicellular organism’s body are made up of tissues formed by cells. To work together cohesively, cells must communicate. One way that cells communicate is through direct contact with other cells. The points of contact that connect adjacent cells are called intercellular junctions.Intercellular junctions are a feature of fungal, plant, and animal cells alike. However, different types of junctions are found in different kinds of cells. Intercellular junctions found in animal...

01:59The Phragmoplast
Cell division is essential for organismal growth and development. In animal cells, the central spindle and its associated proteins form the midbody, a structure that has an essential role in cytokinesis. In plants, the central spindle, along with the microtubules, actin, and other cell components, matures into the phragmoplast, which is necessary for cytokinesis. Unlike the stationary midbody, the phragmoplast expands centrifugally, eventually leading to the formation of the new cell wall.

02:19Morphogenesis
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
