“…Regulation of NLR genes by miRNAs contributes to plant immunity to pathogens (Ouyang et al ., ; de Vries et al ., 2018b). miRNAs seem to preferentially target highly duplicated NLR genes (de Vries et al ., , ,b; Zhang et al ., ). Most miRNA families targeting NLR genes appear to be present only in specific lineages, suggesting recurrent de novo generation of miRNAs targeting NLR genes (Zhang et al ., ).…”

Plants, in turn, have evolved diverse immune strategies to combat microbial pathogens. The conflicts between plants and pathogens result in everchanging coevolutionary cycles known as ‘Red Queen’ dynamics. These ancient and ongoing plant–pathogen interactions have shaped the evolution of both plant and pathogen genomes. With the recent explosion of plant genome‐scale data, comparative analyses provide novel insights into the coevolutionary dynamics of plants and pathogens. Here, we discuss the ancient associations between plants and microbes as well as the evolutionary principles underlying plant–pathogen interactions. We synthesize and review the current knowledge on the origin and evolution of key components of the plant immune system. We also highlight the importance of studying algae and nonflowering land plants in understanding the evolution of the plant immune system.

“…A milestone in the evolution of plants is their conquest of land, a feat accomplished through a partnership with fungi, most commonly mycorrhizae-like association 1,2 . The dramatic habitat transition from water to land posed tremendous challenges for plants, including desiccation, increased UV irradiation and temperature fluctuation, and exposure to novel pathogens 3,4 . In response, early land plants evolved various strategies and features to adapt to hostile terrestrial environments 5,6 .…”

A mycorrhizae-like gene regulates stem cell and gametophore development in mosses

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.

“…[ 21 ]. In the evolution of plants, the common signaling networks governing the defense responses, such as the antagonistic signaling pathways of jasmonic and salicylic acids, multiple independent expansions of resistance genes, and resistance gene-regulating microRNAs, have also undergone complex evolution to cope with pathogen attacks [ 22 ]. In wheat, a large number of genes that function in FHB resistance have been identified, including Fhb1 , plant defensin 1.2 ( pdf1.2 ), chitinase-1 ( Chi -1), glucanase-2 ( Glu - 2 ), uridine diphosphate-glucosyltransferase ( UGTs ), TaWRKY45, and so on [ 23 , 24 , 25 , 26 , 27 , 28 ].…”

Although the war between wheat and Fusarium has been widely investigated for years, long noncoding RNAs (lncRNAs), which have been proven to regulate important processes in the development and stress responses of plants, are still poorly known in wheat against Fusarium. Herein, we systematically reveal the roles of wheat lncRNAs in the process of Fusarium graminearum infection by high-throughput RNA sequencing. Well over 4130 of the total 4276 differentially expressed lncRNAs were already specifically expressed at 12 h postinoculation (hpi), but only 89 of these were specifically expressed at 24 hpi, indicating that the initial stage was the crucial stage for lncRNA-mediated gene regulation of wheat defense against F. graminearum. Target analysis showed the lncRNAs participated in various biological stress processes and had exclusive regulation models at different infection stages. Further H2O2 accumulation and protein ubiquitination assays supported this idea. Moreover, two lncRNAs (XLOC_302848 and XLOC_321638) were identified as Fusarium seedling blight resistance candidates by lncRNA-target expression pattern validation, and two lncRNAs (XLOC_113815, XLOC_123624) were Fusarium head blight resistance potential regulators by cross-validating the RNAseq data with the refined meta-QTL of wheat FHB resistance. These findings extend our knowledge on wheat lncRNAs response to F. graminearum attack and provide new insights for the functional and molecular research of future interactions between wheat and Fusarium.
