Abstract

Summary: An Arabidopsis fatty acid elongase gene, KCS1 , with a high degree of sequence identity to FAE1 , encodes a 3‐ketoacyl‐CoA synthase which is involved in very long chain fatty acid synthesis in vegetative tissues, and which also plays a role in wax biosynthesis. Sequence analysis of KCS1 predicted that this synthase was anchored to a membrane by two adjacent N‐terminal, membrane‐spanning domains. Analysis of a T‐DNA tagged kcs1–1 mutant demonstrated the involvement of the KCS1 in wax biosynthesis. Phenotypic changes in the kcs1–1 mutant included thinner stems and less resistance to low humidity stress at a young age. Complete loss of KCS1 expression resulted in decreases of up to 80% in the levels of C26 to C30 wax alcohols and aldehydes, but much smaller effects were observed on the major wax components, i.e. the C29 alkanes and C29 ketones on leaves, stems and siliques. In no case did the loss of KCS1 expression result in complete loss of any individual wax component or significantly decrease the total wax load. This indicated that there was redundancy in the elongase KCS activities involved in wax synthesis. Furthermore, since alcohol, aldehyde, alkane and ketone levels were affected to varying degrees, involvement of the KCS1 synthase in both the decarbonylation and acyl‐reduction wax synthesis pathways was demonstrated.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
