“…The fatty acid's oxidative stability makes it useful for several industrial applications (Singh et al, 2014(Singh et al, , 2016Rudzińska et al, 2016). The fatty acid content in B. napus and B. juncea oil is normally 5% palmitic, 1% stearic, 15% oleic, 14% linoleic, 9% linolenic, and 45% erucic acid (Rathnakumar and Sujatha, 2022;Varghese et al, 2022). Rapeseed and mustard genotypes having less than 2% erucic acid in oil and less than 30 moles/g glucosinolates in the meal are called double zero (00) or low erucic acid or canola.…”

Rapeseed (Brassica napus L.) and mustard (Brassica juncea L.) are two important oilseed crops grown worldwide for edible oil and meal production, as well as, a source of renewable energy. Silique shattering at the maturity stage is the major cause of seed yield reduction in brassica. Losses in seed yield are more in developing countries due to poor management and the non-availability of combine harvesters. Silique shattering resistance is essential for achieving good seed yield especially in Brassica napus. The silique on plants of rapeseed and mustard mature in different phases due to indeterminate growth habit, which is also a reason for shattering losses. Silique shattering is linked with the creation of a dehiscence zone in a brassica pod. When the siliqua wall loses its hydration, along the length of the siliqua, a few cell layers separate the replum from the pericarp tip of the two silique valves. In the dehiscence zone, it involves the collapse of cell walls and cell separation, as well as, the destruction of the middle lamella and enhanced hydrolytic enzyme activity. To avoid seed yield losses, resistance against silique shattering is essential in rapeseed and mustard cultivars. There are multiple QTLs discovered that control variance in silique shattering. Previous studies validated the shattering process in the model plant Arabidopsis thaliana was controlled by eight different genes. However, their role in controlling silique shattering in rapeseed and mustard is unknown. Modern tools of mutation breeding and genetic engineering, especially CRISPR/Cas9 technology, can be utilized to identify the genetic source for shattering resistance in rapeseed and mustard, which will be helpful for the development of silique-shattering

Edible oilseeds significantly contribute to human nutrition and health. However, the production and consumption of edible oilseeds are facing several challenges, such as limited land and water resources, stress factors, and the quality of edible oils. Owing to its precision and versatility, the technology of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas9 has emerged as a vital tool in the field of oilseed research. CRISPR-Cas9 simplifies the process, allowing scientists to tailor oilseed crops more precisely for industrial applications, nutritional purposes, yield and quality, and stress tolerance. In particular, this technology is playing a crucial role in modifying the fatty acid composition in oilseed crops, addressing industry demands, and is eventually promoting sustainable agriculture. Interestingly, the focus on increasing fatty acid composition is significant for meeting the diverse needs of both industries and consumers. Taking into account relevant literature, this chapter overviews CRISPR-Cas9 system, discusses the major insights into recent applications and achievements of CRISPR-Cas9 in edible oilseed research, addresses the major challenges and proposing solutions for CRISPR/Cas9 editing applications in edible oilseed research, and suggests the themes, so far least explored in the current context.
