“…Polysaccharides are formed either through monosaccharide cytosolic synthesis or within the Golgi apparatus by glycosyl-transferase enzymes (Voiniciuc et al, 2018). The exception are glycoproteins, in which the protein domain is formed within the rough endoplasmic reticulum and is attached to the polysaccharide domain within the Golgi apparatus (Voiniciuc et al, 2018). How these two domains localise together remains unknown.…”

“…Due to the range of molecules present in mucilages and due to their varying accessibility, a variety of methods have been used to isolate them (Table 1). Despite the fact that the composition of each type of mucilage has yet to be fully deciphered, some mono-and polysaccharides as well as glycoproteins that are typically also key architectural components within the plant cell wall appear to be very common in the plant mucilages (Tables 1, 2) (Voiniciuc et al, 2018). AGPs and pectins (RG-I) are the key components in most mucilages, appearing in aerial, haustorial, rhizal and seed coat mucilages (Table 1).…”

“…The molecular mechanisms of mucilage secretion have been mainly investigated using the Arabidopsis seed coat as a model, where special secretory cells are used to produce and exude the mucilage components (Sechet et al, 2018). Polysaccharides are formed either through monosaccharide cytosolic synthesis or within the Golgi apparatus by glycosyl-transferase enzymes (Voiniciuc et al, 2018).

Sticky mucilages and exudates of plants: putative microenvironmental design elements with biotechnological value

Summary Plants produce a wide array of secretions both above and below ground. Known as mucilages or exudates, they are secreted by seeds, roots, leaves and stems and fulfil a variety of functions including adhesion, protection, nutrient acquisition and infection. Mucilages are generally polysaccharide‐rich and often occur in the form of viscoelastic gels and in many cases have adhesive properties. In some cases, progress is being made in understanding the structure–function relationships of mucilages such as for the secretions that allow growing ivy to attach to substrates and the biosynthesis and secretion of the mucilage compounds of the Arabidopsis seed coat. Work is just beginning towards understanding root mucilage and the proposed adhesive polymers involved in the formation of rhizosheaths at root surfaces and for the secretions involved in host plant infection by parasitic plants. In this article, we summarise knowledge on plant exudates and mucilages within the concept of their functions in microenvironmental design, focusing in particular on their bioadhesive functions and the molecules responsible for them. We draw attention to areas of future knowledge need, including the microstructure of mucilages and their compositional and regulatory dynamics.

“…Moreover, they are the main component of the plant biomass that is considered an important source of biofuels and other industrial products in the green chemistry era. In addition to their structural function, CW polysaccharides are also a repository of molecules acting as signals in intercellular communication and as elicitors of immunity during microbial attacks (Bacete et al ., ; Cosgrove, ; Voiniciuc et al ., ).…”

Cell wall traits that influence plant development, immunity, and bioconversion

et al. 2019

Summary The architecture of the plant cell wall is highly dynamic, being substantially re‐modeled during growth and development. Cell walls determine the size and shape of cells and contribute to the functional specialization of tissues and organs. Beyond the physiological dynamics, the wall structure undergoes changes upon biotic or abiotic stresses. In this review several cell wall traits, mainly related to pectin, one of the major matrix components, will be discussed in relation to plant development, immunity and industrial bioconversion of biomass, especially for energy production. Plant cell walls are a source of oligosaccharide fragments with a signaling function for both development and immunity. Sensing cell wall damage, sometimes through the perception of released damage‐associated molecular patterns (DAMPs), is crucial for some developmental and immunity responses. Methodological advances that are expected to deepen our knowledge of cell wall (CW) biology will also be presented.

“…Plant cell walls consist of three predominant polysaccharide carbohydrates: cellulose, hemicellulose, and pectin, which along with cellulose‐hemicellulose networks provide tensile strength (Arsovski et al, ). Pectin supports cell wall integrity by covalently linking to the tensile polysaccharides and by providing cell‐to‐cell adhesion (Voiniciuc et al, , b). The principal pectin in Arabidopsis thaliana primary cell walls is homogalacturonan (HG) (Voiniciuc et al, , b).…”

Camelina sativa L. Crantz (large-seeded false flax) is a promising oilseed crop for the production of edible oil and biodiesel. An ethyl methanesulfonate (EMS) mutant of C. sativa was identified that lacked seed coat mucilage (SCM) using Ruthenium Red (RR) colorimetric staining. Compared with wild-type (WT) plants, the mucilage-defect mutant line (Cs98) had smaller seeds and seeds with significantly less SCM, but exhibited significantly taller plant height. The seed mass and oil content of the seeds of Cs98 were significantly lower than those of WT plants.
