“…Previous studies have shown that plant flavonoids, including phytoalexins, allelochemicals, and signaling molecules, have critical functions in interactions between microbial pathogens and plants [65] and play important roles in improving plant disease resistance [66]. CHI genes are absolutely necessary in the flavonoid biosynthesis pathway [8]. CHI genes play key roles in cotton disease resistance; for instance, the GbCHI protein inhibits the germination of spores and mycelial growth of Verticillium dahliae [16].…”

“…The CHI protein is found in higher plants as a monomer with approximately 220 residues, and its relative molecular weight is approximately 24,000-29,000 units [7]. The CHI protein homology among different species is relatively high at 49% to 82% in different plants [8]. Two major types of CHI genes have been identified in plants.…”

“…Type II CHI proteins are mostly found in leguminous plants and use 6-hydroxy-chalcone as a substrate for 5-deoxy (iso)-flavonoid [9]. It has also been proposed that the proteinoids in fungi and bacteria can be classified as type III [8].…”

Chalcone isomerase (CHI) is a key component of phenylalanine metabolism that can produce a variety of flavonoids. However, little information and no systematic analysis of CHI genes is available for cotton. Here, we identified 33 CHI genes in the complete genome sequences of four cotton species (Gossypium arboretum L., Gossypium raimondii L., Gossypium hirsutum L., and Gossypium barbadense L.). Cotton CHI proteins were classified into two main groups, and whole-genome/segmental and dispersed duplication events were important in CHI gene family expansion. qRT-PCR and semiquantitative RT-PCR results suggest that CHI genes exhibit temporal and spatial variation and respond to infection with Fusarium wilt race 7. A preliminary model of CHI gene involvement in cotton evolution was established. Pairwise comparison revealed that seven CHI genes showed higher expression in cultivar 06-146 than in cultivar Xinhai 14. Overall, this whole-genome identification unlocks a new approach to the comprehensive functional analysis of the CHI gene family, which may be involved in adaptation to plant pathogen stress.

Background Fusarium wilt is a destructive soilborne disease of banana caused by Fusarium oxysporum f. sp. cubense ( Foc ), especially Tropical Race 4 (TR4), which is a xylem-invading fungus. It was evident that xylem sap contained macromolecules, such as proteins, involved in disease-resistance processes. However, there is no research to analyze changes in banana xylem sap proteins response to TR4 to date. Methods To gain an integrated understanding of differential protein expression in banana xylem sap during TR4 infection, we performed a comparative proteomic analysis of xylem sap in resistant ‘Pahang’ and susceptible ‘Brazilian’ bananas inoculated with TR4. Results A total of 1036 proteins were detected in xylem sap of both bananas, among which some proteins are involved in ‘signal transduction’, ‘environmental adaptation’, ‘biosynthesis of secondary metabolites’ and ‘lipid metabolism’, indicating that xylem sap contained defense-related proteins. A number of 129 differential expression proteins (DEPs) were identified in 4 possible pairs between resistant and susceptible tested combinations. Of these DEPs, hypersensitive-induced response protein 1 (HIR1), E3 ubiquitin ligase (E3) might play negative roles in ‘Pahang’ response to TR4 attack, whereas chalcone isomerase (CHI), glycine-rich RNA-binding protein (GRP), carboxylesterase (CXE) and GDSL lipase (GLIP) might play positive roles in ‘Pahang’ defense against TR4 infection. Conclusions Banana xylem sap contained defense-related proteins, among which HIRP1, E3, CHI, GRP, CXE and GLIP involved in banana defense against TR4. To our knowledge, this is first report to analyze changes in banana xylem sap proteins response to TR4, which help us to explore molecular mechanisms of banana resistant to Fusarium wilt.
