Portulaca oleracea | FAD7 is up-regulated by wounding but not by low temperature. Total fatty acid and linolenic acid content are higher both, in wounded and intact leaves of plants exposed to low temperature | up |
Portulaca oleracea | FAD8 is up-regulated by cold stress but not by wounding. Total fatty acid and linolenic acid content are higher both, in wounded and intact leaves of plants exposed to low temperature | up |
