The Role of Cutinsomes in Plant Cuticle Formation

Abstract: The cuticle commonly appears as a continuous lipophilic layer located at the outer epidermal cell walls of land plants. Cutin and waxes are its main components. Two methods for cutin synthesis are considered in plants. One that is based on enzymatic biosynthesis, in which cutin synthase (CUS) is involved, is well-known and commonly accepted. The other assumes the participation of specific nanostructures, cutinsomes, which are formed in physicochemical self-assembly processes from cutin precursors without enzym… Show more

“…We now have a good understanding of the biosynthetic pathways involved in the synthesis of the cuticle “building blocks” (reviewed in Fich et al., 2016 ; Leide et al., 2020 ; Lewandowska et al., 2020 , Table 1 ). Recent studies have also shed light on the mechanisms involved in the delivery and assembly of cuticular components ( Stępiński et al., 2020 , Table 1 ) as well as on the origins and evolution of associated pathways ( Kong et al., 2020 ; Leide et al., 2020 ; Li and Chang, 2021 ). However, the processes that sculpt the cuticle and give the plant epidermis its texture are not well understood.…”

“…Globules of cuticle material of various sizes are well known in the literature (e.g. Buda et al ., 2009; Martin & Rose, 2014; Domínguez et al ., 2017; Strępiński et al ., 2020), and modification of the quantity and organisation of such globules could serve as the developmental mechanism underlying the evolution of the photonic structure in L. strigocamara .…”

“…Some authors postulate the involvement of so-called cutinsomes in the cuticle formation. These are lipid nanoparticles formed by the self-assembly of cutin monomers in water or polar aqueous solutions [ 40 , 56 , 57 ]. Lipid nanoparticles that were observed in the cytoplasm and in cell walls were referred to as cutinsomes.…”

“…Accordingly, cutinsome-based cutin assembly and enzyme-driven polymerization may function in sequence and contribute to various extents to cuticle formation at consecutive stages of organ development, as proposed for tomato fruit [ 58 ]. However, the contribution of cutinsome-based assembly in the formation of the procuticle and cuticle need to be further investigated [ 40 , 57 ].…”
