“…As mentioned above, several studies have reported changes in the DNA methylation status and histone PTMs in specific genes by the exposure of plants to stress factors as drought (Fang et al 2014 ; Kaur et al 2018 ), cold (Pavangadkar et al 2010 ; Tang et al 2018 ), salinity (Sokol et al 2007 ; Yaish et al 2018 ), high light conditions (Guo et al 2008 ), depletion of nutrients as nitrogen and phosphorous (Mager and Ludewig 2018 ), contamination with heavy metals as cadmium (Xin et al 2019 ), exposure to sulphur dioxide (Yi and Li 2013 ), physical wounding (Polkowska-kowalczyk et al 2014 ), and pathogenic bacterial (Latrasse et al 2017 ), viral (Wang et al 2018 ), and fungus (Luo et al 2016 ) infection. Equally, several miRNAs members have been described as functional in response to drought, pathogens (Yu et al 2020 ), heavy metals like cadmium and aluminium, and activating plant immune response by pathogen-associated molecular patterns plant–microbe interactions (Huang et al 2019 ; Sáenz-de la et al 2020 ). Some miRNAs are involved in multiple stresses (Wang et al 2017 ), and in others, their expression pattern varied in a species-specific manner (Álvarez-Venegas et al 2016 ; Banerjee et al 2017 ; Kumar et al 2018 ).…”

Plants are continuously exposed to stress conditions, such that they have developed sophisticated and elegant survival strategies, which are reflected in their phenotypic plasticity, priming capacity, and memory acquisition. Epigenetic mechanisms play a critical role in modulating gene expression and stress responses, allowing malleability, reversibility, stability, and heritability of favourable phenotypes to enhance plant performance. Considering the urgency to improve our agricultural system because of going impacting climate change, potential and sustainable strategies rely on the controlled use of eustressors, enhancing desired characteristics and yield and shaping stress tolerance in crops. However, for plant breeding purposes is necessary to focus on the use of eustressors capable of establishing stable epigenetic marks to generate a transgenerational memory to stimulate a priming state in plants to face the changing environment.

“…The use of model plants such as Arabidopsis, maize [ 383 ], bryophytes such as Physcomitrium patens (formerly Physcomitrella patens ) [ 384 ], halophytes such as Mesembryanthemum cristallinum [ 385 ], Thellungiella halophila , Aeluropus littoralis [ 386 ], resurrection plants such as Craterostigma plantagineum [ 387 ], Selaginella lepidophylla [ 388 ], and Pseudocrossidium replicatum [ 389 ], as well as important crops including barley, potato, soybean, common bean [ 390 ], tomato [ 391 ], among others, have established the bases of plant abiotic stress biochemical, genetic, molecular, and physiological responses. Genome sequencing, gene annotation, functional Omics, and validation of stress tolerance identified genes from model plants as well as from major crops have been vital.…”

The major challenges that agriculture is facing in the twenty-first century are increasing droughts, water scarcity, flooding, poorer soils, and extreme temperatures due to climate change. However, most crops are not tolerant to extreme climatic environments. The aim in the near future, in a world with hunger and an increasing population, is to breed and/or engineer crops to tolerate abiotic stress with a higher yield. Some crop varieties display a certain degree of tolerance, which has been exploited by plant breeders to develop varieties that thrive under stress conditions. Moreover, a long list of genes involved in abiotic stress tolerance have been identified and characterized by molecular techniques and overexpressed individually in plant transformation experiments. Nevertheless, stress tolerance phenotypes are polygenetic traits, which current genomic tools are dissecting to exploit their use by accelerating genetic introgression using molecular markers or site-directed mutagenesis such as CRISPR-Cas9. In this review, we describe plant mechanisms to sense and tolerate adverse climate conditions and examine and discuss classic and new molecular tools to select and improve abiotic stress tolerance in major crops.

“…We speculate that recent speciation events play an important role in the evolution of Arachis. Both underground fruiting and clistogamy are thought to limit gene flows and seed dispersal in peanuts (Tan et al, 2010;Zhang et al, 2017), which should allow each species to keep its distinct identity (Yu et al, 2020). However, it is very interesting to see that the flowers and stems of Arachis plant could attract small insects, such as ants (Supplementary Figure 2).…”

Peanuts (Arachis hypogaea L.) offer numerous healthy benefits, and the production of peanuts has a prominent role in global food security. As a result, it is in the interest of society to improve the productivity and quality of peanuts with transgenic means. However, the lack of a robust phylogeny of cultivated and wild peanut species has limited the utilization of genetic resources in peanut molecular breeding. In this study, a total of 33 complete peanut plastomes were sequenced, analyzed and used for phylogenetic analyses. Our results suggest that sect. Arachis can be subdivided into two lineages. All the cultivated species are contained in Lineage I with AABB and AA are the two predominant genome types present, while species in Lineage II possess diverse genome types, including BB, KK, GG, etc. Phylogenetic studies also indicate that all allotetraploid cultivated peanut species have been derived from a possible maternal hybridization event with one of the diploid Arachis duranensis accessions being a potential AA sub-genome ancestor. In addition, Arachis monticola, a tetraploid wild species, is placed in the same group with all the cultivated peanuts, and it may represent a transitional species, which has been through the recent hybridization event. This research could facilitate a better understanding of the taxonomic status of various Arachis species/accessions and the evolutionary relationship among them, and assists in the correct and efficient use of germplasm resources in breeding efforts to improve peanuts for the benefit of human beings.
