“…The rapid accumulation of genomic data on a large variety of plants will allow increasing integrity of identification of OGs. So far the presence of OGs has been reported in many plants or lineages [such as B. rapa (Jiang et al, 2018), A. thaliana (Yang et al, 2009;Lin et al, 2010;Donoghue et al, 2011;Cui et al, 2015), O. sativa (Guo et al, 2007;Yang et al, 2009;Cui et al, 2015;Jin et al, 2019), P. trichocarpa (Yang et al, 2009), V. unguiculata (Li G. et al, 2019), Poaceae (Campbell et al, 2007), Aegiceras corniculatum (Ma et al, 2021), C. sinensis (Xu et al, 2015), Amaranthus hypochondriacus (Cabrales-Orona and Délano-Frier, 2021), Camellia sinensis (Zhao and Ma, 2021), and eight Cucurbitaceae family members (Ma et al, 2022)]. Every sequenced genome contains OGs whose origins are obscure because of the absence of homologs (Blanco-Melo et al, 2016).…”
