Diploid and polyploid species derived from the euploid series x = 11 occur in the genus Psidium, as well as intraspecific cytotypes. Euploidy in the genus can alter the gene copy number, resulting in several “omics” variations. We revisited the euploidy, reported genomic (nuclear 2C value, GC%, and copy number of secondary metabolism genes) and epigenomic (5-mC%) differences in Psidium, and related them to essential oil yield and composition. Mean 2C values ranged from 0.90 pg (P. guajava) to 7.40 pg (P. gaudichaudianum). 2C value is intraspecifically varied in P. cattleyanum and P. gaudichaudianum, evidencing cytotypes that can be formed from euploid (non-reduced) and/or aneuploid reproductive cells. GC% ranged from 34.33% (P. guineense) to 48.95% (P. myrtoides), and intraspecific variations occurred even for species without 2C value intraspecific variation. Essential oil yield increased in relation to 2C value and to GC%. We showed that P. guajava (diploid) possesses two and P. guineense (tetraploid) four copies of the one specific TPS gene, as well as eight and sixteen copies respectively of the conserved regions that occur in eight TPS genes. We provide a wide “omics'' characterization of Psidium and show the outcome of the genome and epigenome variation in secondary metabolism.

“…Global DNA methylation is known to increase in leaf tissue from seedling to adult age in Arabidopsis thaliana (Baubec et al, 2009) and a few other species (e.g., Perrin et al, 2019;Alves et al, 2020). Furthermore, DNA methylation can change among tissues (Messeguer et al, 1991;Demeulemeester et al, 1999;Seymour et al, 2014;Lloyd and Lister, 2022) and its variation across growth stages (or dates) may change differently on different tissues depending on environmental conditions (Demeulemeester et al, 1999;Seymour et al, 2014;Lloyd and Lister, 2022).…”

Mounting evidence supports the view that the responses of plants to environmental stress are mediated by epigenetic factors, including DNA methylation. Understanding the relationships between DNA methylation, plant development and individual fitness under contrasting environments is key to uncover the potential impact of epigenetic regulation on plant adaptation. Experimental approaches that combine a controlled alteration of epigenetic features with exposure to some relevant stress factor can contribute to this end. We combined the experimental application of a demethylating agent (5-azacytidine) with recurrent drought, and recorded their effects on above- and below-ground phenotypic traits related to early development, phenology and fitness inErodium cicutariumfrom two provenances. We found that 5-azacytidine significantly reduced DNA methylation in leaf and root tissues. Moreover, it slowed plant development, delayed flowering, and reduced the number of inflorescences produced, and such detrimental effects occurred independently of water regime. Recurrent drought reduced final above- and below-ground biomass and total inflorescence production, and such negative effects were unaffected by artificial changes in DNA methylation. Increased fruit and seed-set were the only adaptive responses to drought observed inE. cicutarium, together with an increased number of flowers per inflorescence recorded in water stressed plants previously treated with 5-azacytidine. Thus, epigenetic effects can desynchronize plant growth, flowering and senescence among individual plants in both favourable and adverse environments. Future studies should focus on understanding intraspecific variation in the ability to change plant methylome in response to stress.
