Identification and expression analysis of chitinase genes in parasitic plant Monotropa hypopitys

详细

Genes encoding six chitinases, five of which belong to classes I (MhCHI3 and MhCHI4), IV (MhCHI1), V (MhCHI5), and VII (MhCHI2), were identified in the transcriptome of the parasitic mixoheterotrophic plant Monotropa hypopitys. The transcription level of MhCHI5 and MhCHI1 was low; however, in the leaves (bracts) and roots it was higher than in flowers. MhCHI4 transcripts were detected primarily in the flowers and were almost absent in the roots, whereas the expression level of MhCHI3 was relatively high in all organs but maximum in the leaves (bracts).
