Spatio-temporal distribution patterns of GRF-INTERACTING FACTOR expression and leaf size control

Plant Signaling & Behavior
Byung Ha Lee, Jeong Hoe Kim

Abstract

Developmental biologists have been fascinated with the long-standing mystery of how multicellular organisms, such as plants and animals, sense and control their organ size. In plants, leaves are a suitable experimental system for elucidation of the mystery, because they, like animal organs, inherently exhibit a determinate growth pattern, meaning that they possess genetic information for the control of their final size. The cell proliferation and expansion processes are prerequisites for growth, so that the genetic controls should converge on the 2 cellular processes and decide their rate or duration during leaf growth. Plant scientists have found dozens of genes involved in the control of the cellular processes, including the Arabidopsis thaliana GRF-INTERACTING FACTOR (GIF) family. The GIF family consists of 3 members, GIF1 to GIF3, and encodes a class of transcription co-activators. Although the GIF family genes have been shown to play an essential role in the control of cell proliferation of the leaf organ, understanding of the spatio-temporal behaviors of GIF expression, in both aspects of their promoters and proteins, has been limited to GIF1 (also known as ANGUSTIFOLIA3, AN3). Here, we define kinematic growth properties ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
