The regeneration factors ERF114 and ERF115 regulate auxin-mediated lateral root development in response to mechanical cues. MOLECULAR PLANT 2022; 15:1543-1557. [PMID: 36030378 DOI: 10.1016/j.molp.2022.08.008] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 08/10/2022] [Accepted: 08/23/2022] [Indexed: 06/15/2023]
Abstract
Plants show an unparalleled regenerative capacity, allowing them to survive severe stress conditions, such as injury, herbivory attack, and harsh weather conditions. This potential not only replenishes tissues and restores damaged organs but can also give rise to whole plant bodies. Despite the intertwined nature of development and regeneration, common upstream cues and signaling mechanisms are largely unknown. Here, we demonstrate that in addition to being activators of regeneration, ETHYLENE RESPONSE FACTOR 114 (ERF114) and ERF115 govern developmental growth in the absence of wounding or injury. Increased ERF114 and ERF115 activity enhances auxin sensitivity, which is correlated with enhanced xylem maturation and lateral root formation, whereas their knockout results in a decrease in lateral roots. Moreover, we provide evidence that mechanical cues contribute to ERF114 and ERF115 expression in correlation with BZR1-mediated brassinosteroid signaling under both regenerative and developmental conditions. Antagonistically, cell wall integrity surveillance via mechanosensory FERONIA signaling suppresses their expression under both conditions. Taken together, our data suggest a molecular framework in which cell wall signals and mechanical strains regulate organ development and regenerative responses via ERF114- and ERF115-mediated auxin signaling.

[PMID: 29242229 DOI: 10.1242/jcs.208215] [Citation(s) in RCA: 55] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Accepted: 09/28/2017] [Indexed: 12/22/2022] Open
Abstract
Plants react to wounding through the activation of both defense and repair pathways, but how these two responses are coordinated is unclear. Here, we put forward the hypothesis that diverse members of the subfamily X of the plant-specific ethylene response factor (ERF) transcription factors coordinate stress signaling with the activation of wound repair mechanisms. Moreover, we highlight the observation that tissue repair is strongly boosted through the formation of a heterodimeric protein complex that comprises ERF and transcription factors of the GRAS domain type. This interaction turns ERFs into highly potent and stress-responsive activators of cell proliferation. The potency to induce stem cell identity suggests that these heterodimeric transcription factor complexes could become valuable tools to increase crop regeneration and transformation efficiency.

Abstract
Adventitious rooting is an essential step in vegetative propagation. Currently, the mechanism that regulates adventitious root (AR) development in woody plants is poorly understood. This work demonstrates that Populus tomentosa WUSCHEL-related homeobox 5a (PtoWOX5a) transcription factor is involved in AR development in poplar. PtoWOX5a was specifically expressed in the AR tip and lateral root tip during AR and lateral root regeneration from the stem segment. Phenotypic complementation experiments indicated that the PtoWOX5a can functionally complement AtWOX5 in quiescent center (QC) cells. Overexpression of PtoWOX5a introduces significant developmental phenotypes in roots and leaves, such as increased AR number, decreased AR length, swollen AR tip and lateral root tip, and decreased leaf number and area. The conserved mechanism of D-type cyclins (CYCD) repression mediated by WOX5 was confirmed in poplar. The co-expression network of PtWOX5a was constructed, which provided clues to reveal the molecular mechanism of PtoWOX5a in AR development in poplar. Taken together, our results suggest that the PtoWOX5a is involved in AR development though cooperating with a series of functional genes.

Abstract
In plants, the transcription factor families have been implicated in many important biological processes. These processes include morphogenesis, signal transduction and environmental stress responses. Proteins containing the lateral organ boundaries domain (LBD), which encodes a zinc finger-like domain are only found in plants. This finding indicates that this unique gene family regulates only plant-specific biological processes. LBD genes play crucial roles in the growth and development of plants such as Arabidopsis, Oryza sativa, Zea mays, poplar, apple and tomato. However, relatively little is known about the LBD genes in grape (Vitis vinifera). In this study, we identified 40 LBD genes in the grape genome. A complete overview of the chromosomal locations, phylogenetic relationships, structures and expression profiles of this gene family during development in grape is presented here. Phylogenetic analysis showed that the LBD genes could be divided into classes I and II, together with LBDs from Arabidopsis. We mapped the 40 LBD genes on the grape chromosomes (chr1-chr19) and found that 37 of the predicted grape LBD genes were distributed in different densities across 12 chromosomes. Grape LBDs were found to share a similar intron/exon structure and gene length within the same class. The expression profiles of grape LBD genes at different developmental stages were analysed using microarray data. Results showed that 21 grape LBD genes may be involved in grape developmental processes, including preveraison, veraison and ripening. Finally, we analysed the expression patterns of six LBD genes through quantitative real-time polymerase chain reation analysis. The six LBD genes showed differential expression patterns among the three representative grape tissues, and five of these genes were found to be involved in responses to mannitol, sodium chloride, heat stress and low temperature treatments. To our knowledge, this is the first study to analyse the LBD gene family in grape and provides valuable information for classification and functional investigation of this gene family.

Abstract
The plant-specific LBD (LATERAL ORGAN BOUNDARIES domain) genes belong to a major family of transcription factor that encode a zinc finger-like domain. It has been shown that LBD genes play crucial roles in the growth and development of Arabidopsis and other plant species. However, no detailed information concerning this family is available for apple. In the present study, we analyzed the apple (Malus domestica) genome and identified 58 LBD genes. This gene family was tested for its phylogenetic relationships with homologous genes in the Arabidopsis genome, as well as its location in the genome, structure and expression. We also transformed one MdLBD gene into Arabidopsis to evaluate its function. Like Arabidopsis, apple LBD genes also have a conserved CX2CX6CX3C zinc finger-like domain in the N terminus and can be divided into two classes. The expression profile indicated that apple LBD genes exhibited a variety of expression patterns, suggesting that they have diverse functions. At the same time, the expression analysis implied that members of this apple gene family were responsive to hormones and stress and that they may participate in hormone-mediated plant organogenesis, which was demonstrated with the overexpression of the apple LBD gene MdLBD11, resulting in an abnormal phenotype. This phenotype included upward curling leaves, delayed flowering, downward-pointing flowers, siliques and other abnormal traits. Based on these data, we concluded that the MdLBD genes may play an important role in apple growth and development as in Arabidopsis and other species.

ASYMMETRIC LEAVES2 gene, a member of LOB/AS2 family of Arabidopsis thaliana, causes an abaxializing leaves in transgenic cockscomb. Mol Biol Rep 2011; 39:4927-35. [PMID: 22143880 DOI: 10.1007/s11033-011-1288-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2010] [Accepted: 11/30/2011] [Indexed: 10/15/2022]
Abstract
The leaf primordium derives from the peripheral zone of shoot apical meristem. During the formation of leaf primordia, they need to establish the proximodistal, mediolateral, and ab/adaxial axes. Among these axes, the ab/adaxial axis might be the most important. ASYMMETRIC LEAVES2 (AS2) gene is a member of AS2/LATERAL ORGAN BOUNDARY (LOB) family of Arabidopsis thaliana. In this work, we transformed 35S:AS2 transgene constructs to cockscomb (Celosia cristata) via Agrobacterium tumefaciens. All primary transformants subsequently obtained were placed into phenotypic categories and self-pollinated. As a whole, a total of 44 T1 35S:AS2 cockscomb plants obtained were grouped into two major categories: (I) slightly wrinkled leaves (28/44), (II) extremely curved leaves (16/44), on the basis of their leaf phenotypes. Furthermore, we characterized the anatomical features of these malformed leaves; and found the transformation of adaxial cell types into abaxial cell ones. A series of data suggest that AS2 might be involved in the determination of abaxial polarity in cockscomb plants. However, a few research teams have reported that AS2 might be involved in the determination of adaxial polarity in leaf primodia of Arabidopsis thaliana. These data above indicate that the roles of the same ab/adaxial determinant might differ between distinct species. At last, the different function of AS2 in distinct species was discussed.
