“…Environmentally induced epigenetic variation has been reported to play an important role in enhancing phenotypic plasticity to changing environments [286,287,288,289,290,291]. Though epigenetic variation has been studied and exploited in other crops, perhaps no reports are available on its use for the improvement of pulse crops.…”

Pulses are the main source of protein and minerals in the vegetarian diet. These are primarily cultivated on marginal lands with few inputs in several resource-poor countries of the world, including several in South Asia. Their cultivation in resource-scarce conditions exposes them to various abiotic and biotic stresses, leading to significant yield losses. Furthermore, climate change due to global warming has increased their vulnerability to emerging new insect pests and abiotic stresses that can become even more serious in the coming years. The changing climate scenario has made it more challenging to breed and develop climate-resilient smart pulses. Although pulses are climate smart, as they simultaneously adapt to and mitigate the effects of climate change, their narrow genetic diversity has always been a major constraint to their improvement for adaptability. However, existing genetic diversity still provides opportunities to exploit novel attributes for developing climate-resilient cultivars. The mining and exploitation of adaptive traits imparting tolerance/resistance to climate-smart pulses can be accelerated further by using cutting-edge approaches of biotechnology such as transgenics, genome editing, and epigenetics. This review discusses various classical and molecular approaches and strategies to exploit adaptive traits for breeding climate-smart pulses.

“…The morphology of plant organs [4], seed vigor, and viability [8] change under environmental conditions. They influence both the mechanisms of avoiding/reducing the dose of the stress factor, determined by multiplying the temperature value (the intensive factor) to the duration of exposure (the extensive factor), and the efficiency of the genetic and epigenetic mechanisms of inheriting the primary and adaptive plants resistance to the action of the stress factor [3,9]. We should consider that some epigenetically inherited characteristics can be gradually eliminated [9,10]; therefore, they do not necessarily remain inherited in the next generation.…”

Several morphological and functional mechanisms determine the resistance of plants to extreme temperatures. Depending on the specificity of mechanisms of action, we divided them into two groups: (1) the mechanisms that ensure the avoidance/reduction of the exposure dose; (2) functional mechanisms which increase plant resistance and ability to recover damages caused by stress through regulation metabolic and genes expression activity. We developed theoretical and practical methods to appreciate the contribution of parameters from both groups on the primary and adaptive resistance of different wheat genotypes. This problem became more complicated because some properties are epigenetically inherited and can influence genotypes’ primary (initial) resistance to stressors. The article describes results obtained by the accelerated determination of the initial resistance of wheat (Triticum aestivum L.) genotypes to temperature stress and the prospects for their implementation in the selection and development of methods for rational choosing wheat varieties for cultivation under specific environmental conditions.

“…Several other biotic and abiotic mutagenic stresses such as drought and heating induce dramatic changes that are transmitted (Fleta-Soriano and Munné-Bosch, 2016; Jaligot and Rival, 2016;Probst and Mittelsten Scheid, 2015;Wibowo et al, 2016). Chemical, biological and physical mutagens add a new layer of mutations and epimutations whose types, locations and frequencies may be differentiated from the somaclonal variation-induced changes.…”

Advances in identifying GM plants: toward the routine detection of ‘hidden’ and ‘new’ GMOs

In 2018 the Court of Justice of the European Union recalled that organisms with genomes modified by artifactual techniques should be considered GMOs under European regulations. GMOs derived from cultures of cells isolated in vitro or from new genomic techniques must therefore be traceable. This chapter reviews the various technical steps and characteristics of those techniques causing genomic and epigenomic scars and signatures. These intentional and unintentional traces, some of which are already used for varietal identification, and are being standardized, can be used to identify these GMOs and differentiate them from natural mutants. The chapter suggests a routine procedure for operators and control laboratories to achieve this without additional costs.
