NOTE-Polymorphic information content of SSR markers for Coffea spp.

Crop Breeding and Applied Biotechnology, 2010
Thirty-three coffee SSR primers from enriched genomic library with (GT)15 and (AGG)10 repeats were analyzedin 24 coffee tree accessions. Twenty-two primers were polymorphic among accessions; the number of alleles ranged from 2 to13, with the mean number of 5.1 alleles per primer. PIC values ranged from 0.08 to 0.79.

Pathogen elicitor peptide (pep), systemin, and their receptors in tomato: sequence analysis sheds light on standing disagreements about biotic stress signaling components

BMC Plant Biology
Peps are endogenous damage-associated polypeptides that evoke defense responses in plants. Like other damage-associated molecular patterns, Pep signals are transduced by receptors. PEPRs are the receptors that transduce Pep danger signals.
