Amino acid embedding. Groups Amino Acids. b The P is the weight matrix of a sequence, where a row corresponds to a position in the sequence, columns represent 20 types of amino acids, and n denotes sequence length.

The dissection of R genes and locus Pc5.1 in Phytophthora capsici infection provides a novel view of disease resistance in peppers

tailieu.vn

Snakin-1 (SN1), a well-known antimicrobial peptide gene located at Pc5.1, was significantly decreased in 372S but not in 305R. Conclusions: Those NBS-ARC genes that were suggested to contribute to Pc5.1 in previous publications did not show any significant response in P. Meta-Pc5.1 and Meta-Pc5.3 were positioned close to teach other on the short arm of the chromosome and Meta-Pc5.2 was on the long arm.

Comparative milk proteome analysis of Kashmiri and Jersey cattle identifies differential expression of key proteins involved in immune system regulation and milk quality

tailieu.vn

Similarly, GLYCAM1 with a 7.93-fold expres- sion in Kashmiri cattle is known to act as an antimicrobial peptide with ability to protect the intestinal mucosal tract of neonates largely due to its lubricating properties [34, 35].. In addition to these, apelin peptides might be involved in maturation of the gastrointestinal tract [36, 37].
