“…GmSRS18, as a transcription factor, was located in the cell nucleus, which showed that it functions in cell nucleus. Transcription factors were involved in the abiotic and biotic stress response in many plants [67][68][69][70][71][72]. Though there are few reports of SRS family about the abiotic stress response thus far, we demonstrated that GmSRS18 can increase the transgenic Arabidopsis sensitivity to drought and salt stresses.…”

The plant-special SHI-RELATED SEQUENCE (SRS) family plays vital roles in various biological processes. However, the genome-wide analysis and abiotic stress-related functions of this family were less reported in soybean. In this work, 21 members of soybean SRS family were identified, which were divided into three groups (Group I, II, and III). The chromosome location and gene structure were analyzed, which indicated that the members in the same group may have similar functions. The analysis of stress-related cis-elements showed that the SRS family may be involved in abiotic stress signaling pathway. The analysis of expression patterns in various tissues demonstrated that SRS family may play crucial roles in special tissue-dependent regulatory networks. The data based on soybean RNA sequencing (RNA-seq) and quantitative Real-Time PCR (qRT-PCR) proved that SRS genes were induced by drought, NaCl, and exogenous abscisic acid (ABA). GmSRS18 significantly induced by drought and NaCl was selected for further functional verification. GmSRS18, encoding a cell nuclear protein, could negatively regulate drought and salt resistance in transgenic Arabidopsis. It can affect stress-related physiological index, including chlorophyll, proline, and relative electrolyte leakage. Additionally, it inhibited the expression levels of stress-related marker genes. Taken together, these results provide valuable information for understanding the classification of soybean SRS transcription factors and indicates that SRS plays important roles in abiotic stress responses.

“…To speak to this, a number of TFs that function as positive regulators of polyaliphatic suberin biosynthesis have been identified. These include Arabidopsis AtMYB107 (Gou et al ., 2017), AtMYB9 (Lashbrooke et al ., 2016), AtMYB36 (Wang et al ., 2020), AtMYB39 (Cohen et al ., 2020; Wang et al ., 2020), AtMYB41 (Kosma et al ., 2014), AtMYB92 (To et al, 2020) , AtNAC046 (Mahmood et al ., 2019), AtNAC058 (Markus, 2018), apple ( Malus domestica ) MdMYB93 (Legay et al ., 2016), and kiwi ( Actinidia deliciosa ) AchnMYB41, AchnMYB107, AchnMYC2, and AchnABF2 (Han et al ., 2017; Wei et al ., 2020). Kiwi AchnMYB4 (Wei et al ., 2020) was identified as a negative transcriptional regulator of a kiwi ortholog of FHT .…”

“…Before this study, two other TFs had been implicated in regulating suberin; however, definitive biochemical evidence was not presented (Almeida et al ., 2013; Lasserre et al ., 2008). Since then, a number of TFs that regulate tissue‐ and condition‐specific suberin deposition have been discovered (Cohen et al ., 2020; Gou et al ., 2017; Lashbrooke et al ., 2016; Legay et al ., 2016; Verdaguer et al ., 2016; Wei et al ., 2020).…”

Transcriptional regulation of wound suberin deposition in potato cultivars with differential wound healing capacity

et al. 2021

Wounding during mechanical harvesting and post-harvest handling results in tuber desiccation and provides an entry point for pathogens resulting in substantial post-harvest crop losses. Poor wound healing is a major culprit of these losses. Wound tissue in potato (Solanum tuberosum) tubers, and all higher plants, is composed of a large proportion of suberin that is deposited in a specialized tissue called the wound periderm. However, the genetic regulatory pathway controlling wound-induced suberization remains unknown. Here, we implicate two potato transcription factors, StMYB102 (PGSC0003DMG400011250) and StMYB74 (PGSC0003DMG400022399), as regulators of wound suberin biosynthesis and deposition. Using targeted metabolomics and transcript profiling from the wound healing tissues of two commercial potato cultivars, as well as heterologous expression, we provide evidence for the molecular-genetic basis of the differential wound suberization capacities of different potato cultivars. Our results suggest that (i) the export of suberin from the cytosol to the apoplast and ligno-suberin deposition may be limiting factors for wound suberization, (ii) StMYB74 and StMYB102 are important regulators of the wound suberization process in tubers, and (iii) polymorphisms in StMYB102 may influence cultivar-specific wound suberization capacity. These results represent an important step in understanding the regulated biosynthesis and deposition of wound suberin and provide a practical foundation for targeted breeding approaches aimed at improving potato tuber storage life.

“…Recent studies are showing the importance of distinct clades of the MYB transcription factor family as conserved regulators of suberin deposition in response to osmotic stress in different cell types and in phylogenetically distant plants, linking their evolution with colonization of dry terrestrial environments by early land plants (Capote et al, 2018;Cohen, Fedyuk, Wang, Wu, & Aharoni, 2020;Gou et al, 2017;Kajala et al, 2021;Kosma et al, 2014;Lashbrooke et al, 2016;Legay et al, 2016;Shukla et al, 2021;To et al, 2020;Wei et al, 2020). Two of the possible scenarios are: (1) osmotic stress-inducible regulation of suberization diversified from pre-existing developmental pathways, (2) the regulation of suberization in response to drought was re-activated as plants colonized drier environments.…”

Convergent evolution of gene regulatory networks underlying plant adaptations to dry environments

Plants transitioned from an aquatic to a terrestrial lifestyle during their evolution. On land, fluctuations on water availability in the environment became one of the major problems they encountered. The appearance of morpho-physiological adaptations to cope with and tolerate water loss from the cells was undeniably useful to survive on dry land. Some of these adaptations, such as carbon concentrating mechanisms (CCMs), desiccation tolerance (DT) and root impermeabilization, appeared in multiple plant lineages. Despite being crucial for evolution on land, it has been unclear how these adaptations convergently evolved in the various plant lineages. Recent advances on whole genome and transcriptome sequencing are revealing that co-option of genes and gene regulatory networks (GRNs) is a common feature underlying the convergent evolution of these adaptations. In this review we address how the study of CCMs and DT have provided insight into convergent evolution of GRNs underlying plant adaptation to dry environments, and how these insights could be applied to currently emerging understanding of evolution of root impermeabilization through different barrier cell types. We discuss examples of co-option, conservation, and innovation of genes and GRNs at the cell, tissue and organ levels revealed by recent phylogenomic (comparative genomic) and comparative transcriptomic studies.
