The Arabidopsis ABHD11 Mutant Accumulates Polar Lipids in Leaves as a Consequence of Absent Acylhydrolase Activity  

Abstract: Alpha/beta hydrolase domain (ABHD)-containing proteins are structurally related with diverse catalytic activities. In various species, some ABHD proteins have been characterized and shown to play roles in lipid homeostasis. However, little is known about ABHD proteins in plants. Here, we characterized AT4G10030 (AtABHD11), an Arabidopsis (Arabidopsis thaliana) homolog of a human ABHD11 gene. In silico analyses of AtABHD11 revealed homology with other plant species with a conserved GXSXG lipid motif. Interestin… Show more

“…In Medicago truncatula , this gene was found to regulate the adaptation of roots to salt stress (De Lorenzo et al, ). Moreover, highly downregulated genes, such as linoleate 9S‐lipoxygenase 5 (lipoxygenase), α/β fold family protein, and phospholipase D delta, are involved in the hydrolysis of glycerol–phospholipids that are related to diverse catalytic activities of lipid (Bannenberg, Martínez, Hamberg, & Castresana, ; Vijayakumar, Vijayaraj, Vijayakumar, & Rajasekharan, ; Li et al, , respectively). Another gene for pfkb‐type carbohydrate kinase family protein was downregulated involved in the growth and development of Arabidopsis (Gilkerson, Perez‐Ruiz, Chory, & Callis, ).…”

“…Two encoded lipases for which little was known at the beginning of the study. PLIP1 (At3g61680) is a member of the large a,b-hydrolase gene family, of which some members play a role in lipid metabolism (Ghosh et al, 2009;James et al, 2010;Vijayakumar et al, 2016). Expression of PLIP1 is similar in dgat1-1 and wild-type seeds at 8 and 12 DAF but is more than 2-fold increased in the mutant at 16 DAF (Fig.…”

“…The phospholipase activity of Ddl1 was measured by estimating the FFA release using a fluorescent FFA estimation kit (Cayman Chemical) as reported by Vijayakumar et al (37). Nonfluorescent (native) PE and PG with different fatty acid compositions were also used for the assays.…”
