“…The development of DNA markers in the 1980s laid down the foundation for the use of indirect selection strategies in plant breeding by exploiting host resistance and opened a new avenue, called ‘molecular breeding’ (Rafalski & Tingey, ). This has become self‐sufficient in the rapid and proficient transfer of desired traits into agronomically useful varieties and hybrids (Tanksley et al ., ; Collard & Mackill, ; Panigrahi et al ., ). Broadly, this approach consists of the following steps: Development of genetic resources (mapping populations and germplasms). Development of suitable molecular markers and their characterisation. Establishment of marker(s) to traits linkage either through molecular maps or through gene tagging. Validation of marker–trait association in different genetic backgrounds. Application of the linked DNA markers for marker‐assisted selection and breeding (MASB) programmes. …”

“…A polygenic pattern of inheritance has also been reported in some of the pulse crops, including rice bean, mung bean, black gram and azuki bean (Table ). In many crop plants, polygenic host resistance showed greater durability and stability than those of monogenic across the environments, because of their higher endurance to the effects of genetic changes in insects and pathogens as well as climate change (Panigrahi et al ., ).…”

Bruchids (Callosobruchus spp.) are recognised as the most detrimental storage pest of pulses, especially in the tropics and subtropics. They invade matured pods as well as seeds during storage and, to some extent, farming fields, in turn reducing the net yield of the crops. Several approaches including cultural, biological, physical and chemical control measures have been implemented with the aim of managing these pests, but none of these have been successful across time and space. Recently, transgenic-and marker-assisted breeding approaches have appeared as promising tools for the successful management of these pests. Although some efforts have been made on the development of bruchid-resistant transgenic crops, the cultivars developed are yet to be commercialised worldwide because of various limitations. In contrast, marker-assisted breeding involving the identification of DNA-based markers linked to host resistance against bruchids, have shown some success in the quest for the development of bruchid-resistant cultivar(s). DNA markers linked to bruchid resistance have been identified in various grain legumes, particularly in the genus Vigna, and include mung bean (Vigna radiata), azuki bean (Vigna angularis), rice bean (Vigna umbellata), cowpea (Vigna unguiculata) and black gram (Vigna mungo). After their validation in different genetic backgrounds, these markers could be utilised for marker-assisted selection and breeding ventures to protect pulse crops. The present study discusses the pros and cons of different approaches for the successful management of the bruchid pests in pulses. The review also highlights about the integrative approach aided with molecular interventions to improve productivity by avoiding losses incurred due to bruchids, and to attain sustainable yields for major pulse crops.

“…Monogenic traits are not very common and are normally linked to responses to biotic stresses (e.g., resistance to pests and pathogens). On the contrary, traits related to responses to abiotic stresses or with the start of seasonal physiological processes are largely polygenic [ 41 ]. In simple traits, each gene contributes with a small effect to the phenotype, whereas in complex traits, the phenotype depends on a network of genes that interact in a non-reciprocal way (i.e., the expression of one gene allows or inhibits the expression of others).…”

Climate change poses a novel threat to biodiversity that urgently requires the development of adequate conservation strategies. Living organisms respond to environmental change by migrating to locations where their ecological niche is preserved or by adapting to the new environment. While the first response has been used to develop, discuss and implement the strategy of assisted migration, facilitated adaptation is only beginning to be considered as a potential approach. Here, we present a review of the conceptual framework for facilitated adaptation, integrating advances and methodologies from different disciplines. Briefly, facilitated adaptation involves a population reinforcement that introduces beneficial alleles to enable the evolutionary adaptation of a focal population to pressing environmental conditions. To this purpose, we propose two methodological approaches. The first one (called pre-existing adaptation approach) is based on using pre-adapted genotypes existing in the focal population, in other populations, or even in closely related species. The second approach (called de novo adaptation approach) aims to generate new pre-adapted genotypes from the diversity present in the species through artificial selection. For each approach, we present a stage-by-stage procedure, with some techniques that can be used for its implementation. The associated risks and difficulties of each approach are also discussed.

“…With the advent of DNA markers, two major approaches have been used in exploiting the gene pool for imparting cadmium stress tolerance: fi rst, identifi cation of stress-tolerant genes via functional genomic approaches and introduction of stress-tolerant genes into crops of interest and second, identifi cation of DNA markers fl anking the QTLs or co-segregating with the genes conferring tolerance to cadmium stress and use in marker-assisted breeding programs (Panigrahi et al 2013 ). Although by using functional genomic approaches, regulatory pathways involved in abiotic stress response have been dissected and shown to enhance abiotic stress tolerance in laboratory conditions by activating stress-responsive signal transduction and downstream transcription factor genes in transgenic plants, its success in fi eld conditions are rather poor.…”

Abiotic stresses have major limiting factors for plant growth and crop productivity. Plants have different mechanisms to maintain the physiological concentrations of essential metal ions and to minimize exposure to non-essential heavy metals. Some mechanisms are ubiquitous because they are also required for general metal homeostasis, and they minimize the damage caused by high concentrations of heavy metals in plants by detoxifi cation, thereby conferring tolerance to heavy metal stress. Metals in the cell are addressed using a range of storage and detoxifi cation strategies, including metal transport, chelating, traffi cking, and sequestration into the vacuole. A large number of genes encoding MAPK pathway components have a major role in cell proliferation and hormone action as well as in stress signaling. Germin-like protein genes were developed by various stresses including metal stress. Functional genomics (integrating genome sequencing, transcriptomics, proteomics, metabolomics, ionomics, and phenomics) allows large-scale gene function analysis with high-throughput technology and incorporates interaction of gene products at cellular and organism level.
