The lysin motif-containing proteins, Lyp1, Lyk7 and LysMe3, play important roles in chitin perception and defense against Verticillium dahliae in cotton.

ABSTRACT:

Background

Lysin motif (LysM)-containing proteins are important pattern recognition receptors (PRRs) in plants, which function in the perception of microbe-associated molecular patterns (MAMPs) and in the defense against pathogenic attack. To date, the LysM genes have not been systematically analyzed in cotton or effectively utilized for disease resistance.

Results

Here, we identified 29, 30, 60, and 56 LysM genes in the four sequenced cotton species, diploid Gossypium raimondii, diploid G. arboreum, tetraploid G. hirsutum acc. TM-1, and G. barbadense acc. 3-79, respectively. These LysM genes were classified into four groups with different structural characteristics and a variety of expression patterns in different organs and tissues when induced by chitin or Verticillium da
