Comparative Microscopic, Transcriptome and IAA Content Analyses Reveal the Stem Growth Variations in Two Cultivars Ilex verticillata.

ABSTRACT: Ilex verticillata is not only an excellent ornamental tree species for courtyards, but it is also a popular bonsai tree. 'Oosterwijk' and 'Red sprite' are two varieties of Ilex verticillata. The former has a long stem with few branches, while the latter has a short stem. In order to explain the stem growth differences between the two cultivars 'Oosterwijk' and 'Red sprite', determination of the microstructure, transcriptome sequence and IAA content was carried out. The results showed that the xylem thickness, vessel area and vessel number of 'Oosterwijk' were larger than in 'Red sprite'. In addition, our analysis revealed that the differentially expressed genes which were enriched in phenylpropanoid biosynthesis; phenylalanine metabolism and phenylalanine, tyrosine and trypto
