“…The repressive mark H3K27me3 seems to be conserved in regenerative processes along the plant lineage. Indeed, the ectopic expression of the AP2/ERF-encoding gene STEM CELL-INDUCING FACTOR 1 (STEMIN1) in Physcomitrella patens leaves causes the acquisition of stem cell properties in leaf cells through local reduction of H3K27me3 marks before cell division in a subset of STEMIN1 targets [50].…”

Some plant cells are able to rebuild new organs after tissue damage or in response to definite stress treatments and/or exogenous hormone applications. Whole plants can develop through de novo organogenesis or somatic embryogenesis. Recent findings have enlarged our understanding of the molecular and cellular mechanisms required for tissue reprogramming during plant regeneration. Genetic analyses also suggest the key role of epigenetic regulation during de novo plant organogenesis. A deeper understanding of plant regeneration might help us to enhance tissue culture optimization, with multiple applications in plant micropropagation and green biotechnology. In this review, we will provide additional insights into the physiological and molecular framework of plant regeneration, including both direct and indirect de novo organ formation and somatic embryogenesis, and we will discuss the key role of intrinsic and extrinsic constraints for cell reprogramming during plant regeneration.

“…transcription factors are often linked to stem cell development and cell reprogramming 35 . For instance, AP2-type and AP2-like transcription factors not only determine stem cell identity and gametophore formation, but also induce cell reprogramming in P. patens 17,36 . Homeobox genes are essential for the development of apical meristems in plants 37,38 .…”

Plant colonization of land has been intimately associated with mycorrhizae or mycorrhizaelike fungi. Despite the pivotal role of fungi in plant adaptation, it remains unclear whether and how gene acquisition following fungal interaction might have affected the development of land plants. Here we report a macro2 domain gene in bryophytes that is likely derived from Mucoromycota, a group that includes some mycorrhizae-like fungi found in the earliest land plants. Experimental and transcriptomic evidence suggests that this macro2 domain gene in the moss Physcomitrella patens, PpMACRO2, is important in epigenetic modification, stem cell function, cell reprogramming and other processes. Gene knockout and over-expression of PpMACRO2 significantly change the number and size of gametophores. These findings provide insights into the role of fungal association and the ancestral gene repertoire in the early evolution of land plants.

“…In both cases, the Marchantia genes are not induced by similar environmental cues to Arabidopsis (UVB and osmotic stress, respectively) and plants with altered gene expression developed abnormalities in liverwort synapomorphies, the gemma cup morphology and oil bodies. Also members of the stress‐related AP2/ERF family (MpERF13 and PpSTEMIN) were reported to play divergent functions in bryophytes (Ishikawa et al ., 2019; Kanazawa et al ., 2020). In these cases, where there is not an apparent conserved function, it will be relevant to identify the gene functions hindered by redundancy in seed plants to fully understand the ancestral function.…”

Summary Transcription factors (TFs) are key components of the transcriptional regulation machinery. In plants, they accompanied the evolution from unicellular aquatic algae to complex flowering plants that dominate the land environment. The adaptations of the body plan and physiological responses required changes in the biological functions of TFs. Some ancestral gene regulatory networks are highly conserved, while others evolved more recently and only exist in particular lineages. The recent emergence of novel model organisms provided the opportunity for comparative studies, producing new insights to infer these evolutionary trajectories. In this review, we comprehensively revisit the recent literature on TFs of nonseed plants and algae, focusing on the molecular mechanisms driving their functional evolution. We discuss the particular contribution of changes in DNA‐binding specificity, protein–protein interactions and cis‐regulatory elements to gene regulatory networks. Current advances have shown that these evolutionary processes were shaped by changes in TF expression pattern, not through great innovation in TF protein sequences. We propose that the role of TFs associated with environmental and developmental regulation was unevenly conserved during land plant evolution.
