Mo Z, Zhang Y, Hou M, Hu L, Zhai M, Xuan J. Transcriptional dynamics reveals the asymmetrical events underlying graft union formation in pecan (Carya illinoinensis). TREE PHYSIOLOGY 2024; 44:tpae040. [PMID: 38598328 DOI: 10.1093/treephys/tpae040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 03/25/2024] [Accepted: 04/03/2024] [Indexed: 04/12/2024]
Abstract
Grafting is a widely used technique for pecan propagation; however, the background molecular events underlying grafting are still poorly understood. In our study, the graft partners during pecan [Carya illinoinensis (Wangenh.) K. Koch] graft union formation were separately sampled for RNA-seq, and the transcriptional dynamics were described via weighted gene co-expression network analysis. To reveal the main events underlying grafting, the correlations between modules and grafting traits were analyzed. Functional annotation showed that during the entire graft process, signal transduction was activated in the scion, while messenger RNA splicing was induced in the rootstock. At 2 days after grafting, the main processes occurring in the scion were associated with protein synthesis and processing, while the primary processes occurring in the rootstock were energy release-related. During the period of 7-14 days after grafting, defense response was a critical process taking place in the scion; however, the main process functioning in the rootstock was photosynthesis. From 22 to 32 days after grafting, the principal processes taking place in the scion were jasmonic acid biosynthesis and defense response, whereas the highly activated processes associated with the rootstock were auxin biosynthesis and plant-type secondary cell wall biogenesis. To further prove that the graft partners responded asymmetrically to stress, hydrogen peroxide contents as well as peroxidase and β-1,3-glucanase activities were detected, and the results showed that their levels were increased in the scion not the rootstock at certain time points after grafting. Our study reveals that the scion and rootstock might respond asymmetrically to grafting in pecan, and the scion was likely associated with stress response, while the rootstock was probably involved in energy supply and xylem bridge differentiation during graft union formation.

Proteome plasticity during Physcomitrium patens spore germination - from the desiccated phase to heterotrophic growth and reconstitution of photoautotrophy. THE PLANT JOURNAL : FOR CELL AND MOLECULAR BIOLOGY 2024; 117:1466-1486. [PMID: 38059656 DOI: 10.1111/tpj.16574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 11/13/2023] [Accepted: 11/22/2023] [Indexed: 12/08/2023]
Abstract
The establishment of moss spores is considered a milestone in plant evolution. They harbor protein networks underpinning desiccation tolerance and accumulation of storage compounds that can be found already in algae and that are also utilized in seeds and pollen. Furthermore, germinating spores must produce proteins that drive the transition through heterotrophic growth to the autotrophic plant. To get insight into the plasticity of this proteome, we investigated it at five timepoints of moss (Physcomitrium patens) spore germination and in protonemata and gametophores. The comparison to previously published Arabidopsis proteome data of seedling establishment showed that not only the proteomes of spores and seeds are functionally related, but also the proteomes of germinating spores and young seedlings. We observed similarities with regard to desiccation tolerance, lipid droplet proteome composition, control of dormancy, and β-oxidation and the glyoxylate cycle. However, there were also striking differences. For example, spores lacked any obvious storage proteins. Furthermore, we did not detect homologs to the main triacylglycerol lipase in Arabidopsis seeds, SUGAR DEPENDENT1. Instead, we discovered a triacylglycerol lipase of the oil body lipase family and a lipoxygenase as being the overall most abundant proteins in spores. This finding indicates an alternative pathway for triacylglycerol degradation via oxylipin intermediates in the moss. The comparison of spores to Nicotiana tabacum pollen indicated similarities for example in regards to resistance to desiccation and hypoxia, but the overall developmental pattern did not align as in the case of seedling establishment and spore germination.

Insights into the Jasmonate Signaling in Basal Land Plant Revealed by the Multi-Omics Analysis of an Antarctic Moss Pohlia nutans Treated with OPDA. Int J Mol Sci 2022; 23:13507. [PMID: 36362295 PMCID: PMC9658390 DOI: 10.3390/ijms232113507] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 10/27/2022] [Accepted: 10/28/2022] [Indexed: 09/28/2023] Open
Abstract
12-oxo-phytodienoic acid (OPDA) is a biosynthetic precursor of jasmonic acid and triggers multiple biological processes from plant development to stress responses. However, the OPDA signaling and relevant regulatory networks were largely unknown in basal land plants. Using an integrated multi-omics technique, we investigated the global features in metabolites and transcriptional profiles of an Antarctic moss (Pohlia nutans) in response to OPDA treatment. We detected 676 metabolites based on the widely targeted metabolomics approach. A total of 82 significantly changed metabolites were observed, including fatty acids, flavonoids, phenolic acids, amino acids and derivatives, and alkaloids. In addition, the transcriptome sequencing was conducted to uncover the global transcriptional profiles. The representative differentially expressed genes were summarized into functions including Ca2+ signaling, abscisic acid signaling, jasmonate signaling, lipid and fatty acid biosynthesis, transcription factors, antioxidant enzymes, and detoxification proteins. The integrated multi-omics analysis revealed that the pathways of jasmonate and ABA signaling, lipid and fatty acid biosynthesis, and flavonoid biosynthesis might dominate the molecular responses to OPDA. Taken together, these observations provide insights into the molecular evolution of jasmonate signaling and the adaptation mechanisms of Antarctic moss to terrestrial habitats.

Abstract
Allene oxide synthase (AOS) is a key enzyme involved in the biosynthesis of 12-oxo-phytodienoic acid (OPDA) and jasmonic acid and plays an important role in plant defense against herbivore attacks. In the liverwort, Marchantia polymorpha, we previously identified cytosol-type MpAOS1 and chloroplast-type MpAOS2 that show AOS activities. However, there is no direct evidence to show the subcellular localization of MpAOSs and their contribution to plant defense via OPDA production in M. polymorpha. In this study, we generated M. polymorpha mutants, with the MpAOS1 and MpAOS2 genes disrupted via CRISPR/Cas9-mediated genome editing; the loss of OPDA production was analyzed in double-knockout mutants. On AOS mutants, the survival rate and oviposition of spider mites (Tetranychus urticae) increased relative to those on wild-type plants. Overall, these findings suggest that defense systems via OPDA-signaling pathways in response to spider mites have been established in M. polymorpha.

Abstract
Most known phytohormones regulate moss development. We present a comprehensive view of the synthesis and signaling pathways for the most investigated of these compounds in mosses, focusing on the model Physcomitrium patens. The last 50 years of research have shown that most of the known phytohormones are synthesized by the model moss Physcomitrium patens (formerly Physcomitrella patens) and regulate its development, in interaction with responses to biotic and abiotic stresses. Biosynthesis and signaling pathways are best described in P. patens for the three classical hormones auxins, cytokinins and abscisic acid. Furthermore, their roles in almost all steps of development, from early filament growth to gametophore development and sexual reproduction, have been the focus of much research effort over the years. Evidence of hormonal roles exist for ethylene and for CLE signaling peptides, as well as for salicylic acid, although their possible effects on development remain unclear. Production of brassinosteroids by P. patens is still debated, and modes of action for these compounds are even less known. Gibberellin biosynthesis and signaling may have been lost in P. patens, while gibberellin precursors such as ent-kaurene derivatives could be used as signals in a yet to discover pathway. As for jasmonic acid, it is not used per se as a hormone in P. patens, but its precursor OPDA appears to play a corresponding role in defense against abiotic stress. We have tried to gather a comprehensive view of the biosynthesis and signaling pathways for all these compounds in mosses, without forgetting strigolactones, the last class of plant hormones to be reported. Study of the strigolactone response in P. patens points to a novel signaling compound, the KAI2-ligand, which was likely employed as a hormone prior to land plant emergence.

Metabolomics and physiological analyses validates previous findings on the mechanism of response to wounding stress of different intensities in broccoli. Food Res Int 2021; 140:110058.

Abstract
The mechanism of response of plant to wounding stress is a complex process that physiologically modifies the wounded tissue for protection. In this study, untargeted metabolomics and physiological analyses were performed to validate the molecular mechanism of response to wounding stress of two intensities (0.04 and 1.85 m2 kg-1) in broccoli florets and shreds, respectively. The results showed that 97 and 1220 differentially expressed metabolites could be identified in broccoli subjected to the Florets vs. Control and Shreds vs. Control experiments, respectively. The Kyoto Encyclopedia Genes and Genomes pathway analyses revealed that these metabolites were mainly involved in aminoacyl-tRNA, amino acid, and secondary metabolite biosynthesis; purine metabolism; and plant signal molecule production. This study validated that wounding stress induced plant signal molecule production. Activation of jasmonic acid biosynthesis and H2O2 production were more susceptible to wounding stress of higher intensities, whereas induction of salicylic acid biosynthesis and O2- production were more susceptible to wounding stress of lower intensities. Furthermore, wounding stress also activated glucosinolate and phenylpropanoid biosynthesis by regulating the levels of the precursors, including L-leucine, phenylalanine, tyrosine, valine, isoleucine, tryptophan, methionine, and phenylalanine. Wounding stress induced phenylpropanoid biosynthesis and the antioxidant system by upregulating the corresponding critical enzyme activity and gene expression, contributing greatly to the enhancement of phenolic compound levels, free radical scavenging ability, and resistance to wounding in broccoli.
