It has come to our attention that two references were omitted from this paper. These references should have been cited in the following sentences:

In the RESULTS, sub-section ‘Lipase expression in palms exhibiting various levels of lipase activity’:

Oil palm contains at least two lipase classes, GXSXG and GDSL (unpublished data).

should read:

Oil palm contains at least two lipase classes, GXSXG and GDSL (Nurniwalis et al. 2006, 2015 and unpublished data, respectively).

In the DISCUSSION:

‘The presence of at least two lipase classes in the oil palm, GXSXG and GDSL, was recently confirmed (unpublished data).’

should read:

‘The presence of at least two lipase classes in the oil palm, GXSXG and GDSL, was recently confirmed (Nurniwalis et al. 2006, 2015 and unpublished data, respectively).
