“…According to this categorization, it would only be speculative to propose for them a functional role, but this family is thought to be conserved, and has been proposed to be a new family of carbohydrate-binding proteins [114]. Some of these proteins have shown their ability to bind cellulose [114], have been shown to interact with PME [115], with auxin flux and hypocotyl elongation [116] and germination [117].…”

Plant cell walls mostly comprise polysaccharides and proteins. The composition of monocots’ primary cell walls differs from that of dicots walls with respect to the type of hemicelluloses, the reduction of pectin abundance and the presence of aromatic molecules. Cell wall proteins (CWPs) differ among plant species, and their distribution within functional classes varies according to cell types, organs, developmental stages and/or environmental conditions. In this review, we go deeper into the findings of cell wall proteomics in monocot species and make a comparative analysis of the CWPs identified, considering their predicted functions, the organs analyzed, the plant developmental stage and their possible use as targets for biofuel production. Arabidopsis thaliana CWPs were considered as a reference to allow comparisons among different monocots, i.e., Brachypodium distachyon, Saccharum spp. and Oryza sativa. Altogether, 1159 CWPs have been acknowledged, and specificities and similarities are discussed. In particular, a search for A. thaliana homologs of CWPs identified so far in monocots allows the definition of monocot CWPs characteristics. Finally, the analysis of monocot CWPs appears to be a powerful tool for identifying candidate proteins of interest for tailoring cell walls to increase biomass yield of transformation for second-generation biofuels production.

“…In flowers of Arabidopsis, BDX was expressed in petals, vascular tissue of the filament, anther, and stigmatic papilla. At5g11420 was expressed in petals and abscission zones of floral whorls, TEB was expressed only in stigmatic papilla, and At3g08030 was expressed in the replum of androecium and epidermis of the filaments of stamens [13,18] (Figure S1).…”

“…The At5g11420 protein was present in the proteomes of apoplast, hypocotyls, and mature stems, whereas BDX was found only in the mature stem cell wall proteome [28]. The localization of BDX and TEB in the Arabidopsis cell wall was confirmed by confocal microscopy in hypocotyl cells [18,19]. The VqDUF642 protein was localized in the cell wall of tobacco epidermal cells [15] and peach PpDU642 (TEB) was localized in the cell wall and extracellular space during a transient expression in tomato fruit [29].…”

The At4g32460 / bdx mutants had shorter siliques, seeds with altered development, and longer hypocotyl than the wild-type [18]. Among Arabidopsis Clade A2 mutants, the At2g41800/teb mutant is the only one for which a phenotype (longer hypocotyls) has been established [19].…”

The DUF642 protein family is found exclusively in spermatophytes and is represented by 10 genes in Arabidopsis and in most of the 24 plant species analyzed to date. Even though the primary structure of DUF642 proteins is highly conserved in different spermatophyte species, studies of their expression patterns in Arabidopsis have shown that the spatial-temporal expression pattern for each gene is specific and consistent with the phenotypes of the mutant plants studied so far. Additionally, the regulation of DUF642 gene expression by hormones and environmental stimuli was specific for each gene, showing both up- and down-regulation depending of the analyzed tissue and the intensity or duration of the stimuli. These expression patterns suggest that the DUF642 genes are involved throughout the development and growth of plants. In general, changes in the expression patterns of DUF642 genes can be related to changes in pectin methyl esterase activity and/or to changes in the degree of methyl-esterified homogalacturonans during plant development in different cell types. Thus, the regulation of pectin methyl esterases mediated by DUF642 genes could contribute to the regulation of the cell wall properties during plant growth.

Premise Flowering plants have evolved a vast array of floral features involved in plant–pollinator interactions. A feature that seemingly increases the chance of pollen transfer is the androgynophore, a stalk‐like structure that raises the reproductive organs of the flower. However, little is known about the developmental and genetic basis of this structure despite its presence in multiple, distantly related taxa. Here, we address this gap by investigating Gynandropsis gynandra (Cleomaceae), a species with a prominent androgynophore. Methods We combined morphological and anatomical analyses with a comparative transcriptomic study to provide a detailed description of the androgynophore throughout development, examine global gene expression patterns, and identify candidate genes putatively involved in androgynophore elongation. Results The radially symmetric androgynophore of G. gynandra rapidly lengthens primarily via cell elongation. Despite its structural uniformity, androgynophore development is characterized by complex gene expression patterns including differential expression of floral organ identity genes and genes associated with organ development and growth in Arabidopsis thaliana. Conclusions Our morphological characterizations and high‐quality transcriptome for G. gynandra suggest that the androgynophore is a novel structure formed via elaboration of both the receptacle and base of reproductive organs because it is structurally like an elongated internode but expresses the genetic repertoire typically associated with the reproductive organs. The drastic increase in cell length and uniform structure elevates the androgynophore as a potentially powerful model for cell elongation.
