Plant responses to pathogen attack: molecular basis of qualitative resistance

Plant Responses to Pathogen Attack: Small RNAs in Focus

Small RNAs (sRNA) are a significant group of gene expression regulators for multiple biological processes in eukaryotes. In plants, many sRNA silencing pathways produce extensive array of sRNAs with specialized roles. The evidence on record advocates for the functions of sRNAs during plant microbe interactions. Host sRNAs are reckoned as mandatory elements of plant defense. sRNAs involved in pl...

Molecular Characterization of Carbendazim Resistance of Plant Pathogen (Bipolaris oryzae)

Plant Resistance Responses to Viruses

Plants have developed numerous approaches to resist infection by viruses. On the other hand, in many instances viruses have evolved to overcome these various resistance responses and barriers. The extent to which viruses can overcome some or all of these responses and barriers determines the extent to which they are able to colonize plants of a given genotype or species. Resistance against plan...

Molecular recognition of pathogen attack occurs inside of plant cells in plant disease resistance specified by the Arabidopsis genes RPS2 and RPM1.

The Arabidopsis thaliana disease resistance genes RPS2 and RPM1 belong to a class of plant disease resistance genes that encode proteins that contain an N-terminal tripartite nucleotide binding site (NBS) and a C-terminal tandem array of leucine-rich repeats. RPS2 and RPM1 confer resistance to strains of the bacterial phytopathogen Pseudomonas syringae carrying the avirulence genes avrRpt2 and ...

Genetics of plant-pathogen interactions specifying plant disease resistance.

Understanding the mechanistic basis of why a certain pathogen causes disease in one host plant and not in another has long intrigued and motivated plant pathologists. Plants, in nature, are generally resistant to most pathogens. The ability of a pathogen to cause disease in a host plant is usually the exception, not the rule. This is because plants have an innate ability to recognize potential ...
