Directing Effect of Substituents: meta-Directing Groups

Directing Effect of Substituents: meta-Directing Groups

Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

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.

Tonicity in Plants

Tonicity in Plants

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.

T Cell Activation and Clonal Selection

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Plant Cell Wall

Plant 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.

Plant Cells and Tissues

Plant Cells and Tissues

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

This summary is machine-generated.

The meta-holobiont concept extends the holobiont framework to networks of organisms, like clonal plants, that exchange microbes across generations. This microbial exchange impacts the fitness of both individual holobionts and the larger meta-holobiont network.

Area of Science:

Ecology
Evolutionary Biology
Microbiology

Background:

The holobiont concept views an organism and its symbionts as a unit of selection.
Clonal plants exhibit vertical microbiota transmission between ramets within a network.

Purpose of the Study:

To propose the meta-holobiont concept, extending the holobiont framework to networked organisms.
To describe how microbial exchange across generations influences fitness at multiple biological scales.

Main Methods:

Conceptual framework development.
Literature synthesis.
Hypothesis generation for future empirical studies.

Main Results:

The meta-holobiont concept is introduced, defining a network of holobionts exchanging microbiota across generations.
Meta-holobiont dynamics can lead to microbial sharing, specialization, and division of labor.
This framework applies to clonal plants and potentially other systems like social insects.

Conclusions:

The meta-holobiont concept provides a novel perspective on the evolution of microbial communities in networked organisms.
This concept is expected to stimulate research into intergenerational microbial exchange and its ecological and evolutionary consequences.
The framework has broad applicability beyond clonal plants, including social insects and other meta-organismal systems.
