“…Conventional plant breeding approaches have been integral in developing agronomically important traits in various crops, improving crop production, productivity and resilience. For example, conventional breeding approaches, including marker‐assisted selection, have improved broad disease resistance in rice (Luo et al, 2017; Suh et al, 2013), potato (Haverkort et al, 2016; Zhu et al, 2012) and wheat (Aktar‐Uz‐Zaman et al, 2017; Liu et al, 2000). Breeding and selection of rice has resulted in the loss of seed dispersal, increased apical dominance, decreased seed dormancy, compact panicles and larger inflorescences and grains throughout its domestication (Doebley et al, 2006; Ishii et al, 2013; Zhu et al, 2013).…”

Conventional breeding techniques have been integral to the development of many agronomically important traits in numerous crops. The adoption of modern biotechnology approaches further advanced and refined trait development and introduction beyond the scope possible through conventional breeding. However, crop yields continue to be challenged by abiotic and biotic factors that require the development of traits that are more genetically complex than can be addressed through conventional breeding or traditional genetic engineering. Therefore, more advanced trait development approaches are required to maintain and improve yields and production efficiency, especially as climate change accelerates the incidence of biotic and abiotic challenges to food and fibre crops. Synthetic biology (SynBio) encompasses approaches that design and construct new biological elements (e.g., enzymes, genetic circuits, cells) or redesign existing biological systems to build new and improved functions. SynBio 'upgrades' the potential of genetic engineering, which involves the transfer of single genes from one organism to another. This technology can enable the introduction of multiple genes in a single transgenic event, either derived from a foreign organism or synthetically generated. It can also enable the assembly of novel genomes from the ground up from a set of standardised genetic parts, which can then be transferred into the target cell or organism. New opportunities to advance breeding applications through exploiting SynBio technology include the introduction of new genes of known function, artificially creating genetic variation, topical applications of small RNAs as pesticides and potentially speeding up the production of new cultivars with elite traits. This review will draw upon case studies to demonstrate the potential application of SynBio to improve crop productivity and resistance to various challenges. Here, we outline specific solutions to challenges including fungal diseases, insect pests, heat and drought stress and nutrient acquisition in a range of important crops using the SynBio toolkit.

“…An elite maintainer line IR58025B was improved against blast disease by introducing Pi54 gene by MABB (Hari et al 2013 ). So far more than 100 rice blast R genes ( Pi loci) and about 350 resistance quantitative trait loci (QTLs) of major and minor genes governing true resistance and partial resistance, respectively, have been genetically identified (Tanweer et al 2015 ; Ashkani et al 2016 ; Devanna and Sharma ( 2017 ) and about 25R genes have been cloned and characterized at the molecular level (Koide et al 2009 ; Sharma et al 2012 ; Luo et al 2017 ).…”

“…A few of these blast resistance genes have already been incorporated into rice varieties that are now widely cultivated in many countries [ 6 , 7 , 8 , 9 , 10 ]. Among the blast resistance genes found in rice varieties grown in China, Pi2 has been identified as one of the most effective genes, providing broad-spectrum resistance to rice blast [ 11 , 12 , 13 ]. The Pi2 gene, existing in the indica rice line BL6, was introgressed from the wild species Oryza minuta [ 14 ].…”

Rice production is often affected by biotic and abiotic stressors. The breeding of resistant cultivars is a cost-cutting and environmentally friendly strategy to maintain a sustainable high production level. An elite water-saving and drought-resistant rice (WDR), Hanhui3, is susceptible to blast and bacterial blight (BB). This study was conducted to introgress three resistance genes (Pi2, xa5, and Xa23) for blast and BB into Hanhui3, using marker-assisted selection (MAS) for the foreground selection and a whole-genome single-nucleotide polymorphism (SNP) array for the background selection. As revealed by the whole-genome SNP array, the recurrent parent genome (RPG) recovery of the improved NIL was 94.2%. The resistance levels to blast and BB of the improved NIL and its derived hybrids were higher than that of the controls. In addition, the improved NIL and its derived hybrids retained the desired agronomic traits from Hanhui3, such as yield. The improved NIL could be useful to enhance resistance against biotic stressors and produce stable grain yields in Oryza sativa subspecies indica rice breeding programs.
