This approach helps in identifying proteins that play crucial roles in stress tolerance and can be targeted for genetic improvement (Alotaibi et al., 2020). The integration of these omics technologies with bioinformatics tools has facilitated the mapping of quantitative trait loci (QTLs) and genome-wide association studies (GWAS), which are essential for dissecting complex traits and accelerating the breeding of superior wheat varieties (Alotaibi et al., 2020; Babu et al., 2020). 6.3 Synthetic biology for innovation in wheat variety development Synthetic biology offers innovative approaches to wheat variety development by enabling the design and construction of novel genetic circuits and pathways. This field leverages the principles of engineering to create synthetic gene networks that can introduce new traits or enhance existing ones in wheat (Paux et al., 2022). For instance, synthetic biology can be used to develop wheat varieties with enhanced photosynthetic efficiency, nutrient use efficiency, and stress resilience, thereby improving yield and sustainability (Paux et al., 2022). The potential of synthetic biology in wheat breeding is further amplified by its ability to integrate with other biotechnological tools, such as genome editing and omics technologies. This integration allows for the precise manipulation of metabolic pathways and regulatory networks, leading to the development of wheat varieties that are better suited for mechanized farming and changing agricultural landscapes (Paux et al., 2022). By harnessing the power of synthetic biology, breeders can create wheat varieties that not only meet current agricultural demands but also anticipate future challenges posed by climate change and resource limitations (Paux et al., 2022). 7 Strategies for Improving Mechanization-Friendly Wheat Varieties 7.1 Optimizing plant height and spike architecture for better compatibility with machinery Optimizing plant height and spike architecture is crucial for enhancing the compatibility of wheat varieties with mechanized farming. Shorter plant height can reduce the risk of lodging, which is essential for efficient mechanical harvesting. Lodging resistance is a key trait that needs to be improved alongside yield potential to ensure that wheat plants can withstand the mechanical forces exerted by harvesting equipment without collapsing (Foulkes et al., 2011; Reynolds et al., 2011). Additionally, optimizing spike architecture to maximize grain number and dry matter harvest index can further enhance the efficiency of mechanized harvesting by ensuring uniformity and ease of processing (Foulkes et al., 2011; Reynolds et al., 2012). Moreover, the integration of advanced breeding techniques, such as genomic selection, can facilitate the development of wheat varieties with optimized plant height and spike architecture. By employing genomic selection, breeders can efficiently select for traits that improve the structural integrity of wheat plants, thereby enhancing their suitability for mechanized farming (Merrick et al., 2022). This approach allows for the rapid development of varieties that meet the specific requirements of mechanized agriculture, ultimately improving yield and processing efficiency (Reynolds et al., 2011; Merrick et al., 2022). 7.2 Enhancing root structures to improve tolerance to abiotic stresses Enhancing root structures is vital for improving wheat's tolerance to abiotic stresses, which is crucial for mechanized farming systems that often involve large-scale operations with less frequent human intervention. Strong root systems can improve water and nutrient uptake, thereby increasing the plant's resilience to drought and nutrient-poor conditions (Foulkes et al., 2011; Reynolds et al., 2012). This resilience is essential for maintaining high yields in mechanized systems where environmental conditions can vary significantly (Romanenko et al., 2007). In addition to improving stress tolerance, robust root systems can also contribute to better anchorage, reducing the risk of lodging during mechanical operations. This dual benefit of enhanced root structures supports both the physiological and structural needs of wheat plants in mechanized farming environments. Breeding programs that focus on root architecture, alongside other agronomic traits, can lead to the development of wheat varieties that are better suited to withstand the challenges posed by mechanized agriculture (Romanenko et al., 2007; Foulkes et al., 2011).
