A crispa null mutant facilitates identification of a crispa-like pseudogene in pea

Abstract

The genomes of several legume species contain two Phantastica-like genes. Previous studies on leaf development have found that Phantastica confers leaf blade adaxial identity in plant species with simple leaves and leaflet adaxial identity in pea (Pisum sativum L.), a legume with compound leaves. Previous characterisation of the phantastica mutant of pea, crispa, showed it had radialised leaflets, but stipules were not radialised. This suggested either that mutation of a second redundant gene was required for radialisation of stipules, or, that a null mutation was required. Previously characterised crispa mutants may not have exhibited radialised stipules because they were weak alleles. In this work we show that pea has a second Phantastica-like gene, which lies on a different chromosome to Crispa. The second gene was found to be a pseudogene in several genotypes of pea, therefore it would not have a role in conferring stipule adaxial identity. A new deletion mutant, crispa-4 was identified. The mutant has radialised stipules and leaflets, showing that Crispa confers adaxial identity on both these organs in pea. The nucleotide sequence data reported here are in the EMBL and GenBank Nucleotide Databases under the accession numbe...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.
