“…Stress upregulates the expression of expansins and xyloglucan-modifying enzymes that can remodel the wall under abiotic stress [49]. In Medicago truncatula , XTH respond to heavy metal mercury, salinity and drought stresses [50], possibly through incorporating newly deposited xyloglucan to strengthen cell walls. However, the role of similar CWPs in maize under abiotic stresses needs to be characterized.…”

12As the vital component of plant cell wall, proteins play important roles in stress response 13 through modifying wall structure and involving in wall integrity signaling. However, the 14 potential of cell wall proteins (CWPs) in improvement of crop stress tolerance has probably 15 been underestimated. Recently, we have critically reviewed the predictors, databases and 16 cross-referencing of subcellular locations of possible CWPs in plants (Briefings in 17 Bioinformatics 2018;19:1130-1140). In this study, taking maize (Zea mays) as an example, 18 we retrieved 1873 entries of probable maize CWPs recorded in UniProtKB. As a result, 863 19 maize CWPs are curated and classified as 59 kinds of protein families. By referring to GO 20 annotation and gene differential expression in Expression Atlas, we highlight the potential of 21 CWPs as defensive forwards in abiotic and biotic stress responses. In particular, several 22 CWPs are found to play key roles in adaptation to many stresses. String analysis also reveals 23 possibly strong interactions among many CWPs, especially those stress-responsive enzymes. 24The results allow us to narrow down the list of CWPs to a few specific proteins that could be 25 candidates to enhance maize resistance. 26

“…DcXTH2 and DcXTH3 from Dianthus caryophyllus mainly expressed in petals [21]. XTH activity was detected during the fruit expansion of Solanum lycopersicum, Malus domestica, Actinidia chinensis, and strawberry (Fragaria × ananassa Duch) [22][23][24]. Constitutive expression of Brassica campestris BcXTH1 caused owering branches elongation and height increased in transgenic Arabidopsis plants [25].…”

Background Xyloglucan endotransglucosylase/hydrolase genes (XTHs) are a multigene family and play key roles in regulating cell wall extensibility in plant growth and development. XTH genes of Brassica have not been reported. Results In this study, 53 and 38 XTH genes were identified in Brassica rapa and Brassica olerecea, respectively. All XTHs of B. rapa, B. oleracea and Arabidopsis thaliana can be classified into three groups including Group I/II, III and Ancestral Group based on phylogenetic relationships. Gene structures and motif patterns were similar in the same group. All XTHs in this study contained two characteristic conserved domains (Glyco_hydro and XET_C). XTHs mainly located in the cell wall and some also located in cytoplasm. Expansion mechanism analyses uncovered that whole-genome triplication (WGT) events and tandem duplication (TD) may be the major mechanism accounting for the expansion of XTH gene family. Interestingly, TD genes were all belong to Group I/II, which suggested TD was the main reason for the largest number of genes in the groups. B. oleracea had a higher loss rate of XTH genes, conserved domain XET_C and conserved motif EXDXE compared with B. rapa, consistent with the asymmetrical evolution between the two Brassica genomes. A majority of XTH genes exhibited different tissue-specific expression patterns based on RNA-seq data analyses. Moreover, the differential expressions of duplicated XTH genes in the two species were found and indicated their functional differentiation occurred after B. rapa and B. olerecea diverged from a common ancestor. Conclusions We first systematic analyzed XTH gene families in B. rapa and B. oleracea. The results of this paper can be used for reference to further study the function of XTH gene and the evolution pattern of multi gene family.
