Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases.
Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [ 1 ] [ 2 ] It is generally considered a field of biology and botany , but intersects frequently with many other life sciences and is strongly linked with the study of information systems .
Studied R genes usually confer specificity for particular strains of a pathogen species (those that express the recognized effector). As first noted by Harold Flor in his mid-20th century formulation of the gene-for-gene relationship, a plant R gene has specificity for a pathogen avirulence gene (Avr gene). Avirulence genes are now known to ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
One is a plant gene called the resistance gene. The other is a parasite gene called the avirulence (Avr) gene. Plants producing a specific R gene product are resistant towards a pathogen that produces the corresponding Avr gene product. [5] Gene-for-gene relationships are a widespread and very important aspect of plant disease resistance.
A regulatory gene that restricts the expression of other genes to specific tissues or body parts in an organism, typically by producing gene products which variably inhibit or permit transcription of the other genes in different cell types. [4] The term is used most commonly in plant genetics. cadherin
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
