Features of m6A RNA methylation in plants. a Summary of key features of m6A methylation in plants. Plant species with known m6A profiles on a global scale are shown in a phylogenetic tree (left). The key m6A features (right) are summarized based on the studies in Pyrus bretschneideri (pear) [116], Malus hupehensis (apple) [108], Fragaria vesca (strawberry) [117], Hippophae rhamnoides (sea-buckthorn) [118], Glycine max (soybean) [27], Populus trichocarpa (populus) [119,120,121], Brassica rapa (pak-choi) [122], Arabidopsis thaliana (Arabidopsis) [28, 29], Gossypium hirsutum (cotton) [133, 136], Solanum lycopersicum (tomato) [97, 123, 124], Triticum aestivum (common wheat) [125, 126], Aegilops tauschii (rough-spike hard grass) [27], Oryza sativa (rice) [92, 127], Sorghum bicolor (sorghum) [128], Zea mays (maize) [134], Physcomitrella patens (earthmoss) [27], and Chlamydomonas reinhardtii (green algae) [130]. Among these features, the “correlation with gene expression” is shown at the transcriptome-wide basis. R = A/G; W = A/U; K = G/U; Y = C/U; D = A/G/U; H = A/C/U; V = A/G/C. b m6A modifications are influenced by various endogenous and environmental signals as shown in the following studies: developmental stages (strawberry [117], wheat [125]); different organs (Arabidopsis [137]); ecotype divergence (Arabidopsis [138]); blue light (Arabidopsis [79]); salt stress (Arabidopsis [139, 140], sweet sorghum [128], rice [141], sugar beet [142], cotton [133]); heat/low temperature (pak-choi [122], Arabidopsis [143], tomato [124]); cadmium stress (rice [127], barley [132]); drought stress (sea-buckthorn [118], populus [119], apple [135, 144]); pathogen infection (apple [108], rice [145], wheat [126], watermelon [131], pear [116]); and nematode infection (soybean [146]). c Expression of m6A writer and eraser genes are modulated by multiple external stimuli in Arabidopsis.
