“…In addition, some XTHs also located on cytoplasm and they all belong to Group I/II. These ndings were similar to that reported in barley, pineapple and so on [11,18]. Interestingly, TD genes are all belong to Group I/II, which suggested TD is the reason of the large number in the group.…”

“…It re ects the ampli cation of tandem repeat genes is asymmetric between the two species. Tandem duplication also contributed to XTH gene expansion in barley, tobacco, sorghum, and soybean [11,15,44,45] Since the Brassica ancestor diverged from a common ancestor with A. thaliana at ~20 Mya; subsequently, the Brassica ancestor underwent WGT event at ~15.9 Mya. Then, the Brassica ancestor diverged to form the modern B. rapa and B. oleracea about 3.75 Mya [33][34][35][36].…”

“…XTHs have been widely reported in many plants, such as Arabidopsis thaliana (33 genes), Oryza sativa (29 genes), Populus tomentosa (33 genes), Solanum lycopersicum (25 genes), Nicotiana tabacum (56 genes), Glycine max (61 genes), Hordeum vulgare (24 genes) and Ananas comosus (24 genes) [11][12][13][14][15][16][17][18].

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.

“…Endo-1,3(4)-β-D-glucanase has A specific digestive effect on cellulose microfibers and plays an important role in regulating plant cell wall structure [55] . Xyloglucan endotransglucosylase/hydrolases (XTHs) is a family of xyloglucan modifying enzymes that play an essential role in the construction and restructuring of xyloglucan cross-links [56] . In general, the upregulation of these genes led us to speculate that beet leaves respond to salt stress by maintaining the ductility of cell walls.…”

Background Salinity is one of the most serious threat to agriculture worldwide. Sugar beet is an important sugar-yielding crop and has a certain tolerance to salt. However, the molecular mechanism of salt tolerance in beta vulgaris are poorly understood. Proteomics can provide a new perspective and deeper understanding for the research of beet salt-tolerant. Results Here, leaves and roots were used to identify the differentially abundant protein species between salt-stress and control conditions in beta vulgaris. As a result, 70 and 76 DAPs were identified in leaves and roots, respectively. The functions were determined for the classification of the DAPs, mainly involved in cellular processes, environmental information processing, genetic information processing and metabolism. These processes can work cooperatively to reconstruct the favorable equilibrium of physiological and cellular homeostasis under salt stress. Some candidate DAPs are closely related to salt resistance such as choline monooxygenase, betaine aldehyde dehydrogenase, glutathione S-transferase (GST) and F-type H+-transporting ATPase. The expressional pattern of 10 DAPs encoding genes were consistent with the iTRAQ data. Conclusions Our results demonstrated that during adaptation of beet to salt stress, leaves and roots have distinct mechanisms of molecular metabolism regulation. This study provided some significative insights into the molecular mechanism underlying the response of higher plant to salt stress, and identified some candidate proteins against salt stress.

Background: Salinity is one of the most serious threats to world agriculture. An important sugar-yielding crop sugar beet, which shows some tolerance to salt via a mechanism that is poorly understood. Proteomics data can provide important clues that can contribute to finally understand this mechanism.Results: Differentially abundant proteins (DAPs) in sugar beet under salt stress treatment were identified in leaves (70 DAPs) and roots (76 DAPs). Functions of these DAPs were predicted, and included metabolism and cellular, environmental information and genetic information processing. We hypothesize that these processes work in concert to maintain cellular homeostasis. Some DAPs are closely related to salt resistance, such as choline monooxygenase, betaine aldehyde dehydrogenase, glutathione S-transferase (GST) and F-type H+-transporting ATPase. The expression pattern of ten DAPs encoding genes was consistent with the iTRAQ data.Conclusions: During sugar beet adaptation to salt stress, leaves and roots cope using distinct mechanisms of molecular metabolism regulation. This study provides significant insights into the molecular mechanism underlying the response of higher plants to salt stress, and identified some candidate proteins involved in salt stress countermeasures.
