Prolyl 4-hydroxylase genes are subjected to alternative splicing in roots of maize seedlings under waterlogging.

ABSTRACT:

Background

In animals, prolyl 4-hydroxylases (P4Hs) are regarded as oxygen sensors under hypoxia stress, but little is known about their role in the response to waterlogging in maize.

Methods

A comprehensive genome-wide analysis of P4H genes of maize (zmP4H genes) was carried out, including gene structures, phylogeny, protein motifs, chromosomal locations and expression patterns under waterlogging.

Key results

Nine zmP4H genes were identified in maize, of which five were alternatively spliced into at least 19 transcripts. Different alternative splicing (AS) events were revealed in different inbred lines, even for the same gene, possibly because of organ and developmental specificities or different stresses. The signal strength of splice sites was strongly correlated w
