“…The AC and GC were measured using standard procedures as described previously. The AC was determined using a colorimetric method with KI-I 2 and measured by a continuous flow analyzer (Futura-II) with the manufacturer’s protocol; GC was measured as the gel length, with longer gels being considered softer than shorter gels 34 . The paste viscosity of rice starch was measured using a RVA profile by RVA-TecMaster (Perten, Sweden).…”

Rice quality is one of the main targets of rice breeding and is a complex trait that involves grain appearance, milling, cooking, eating and nutritional quality. For many years, rice breeding has contended with imbalances in rice yield, quality, and disease and lodging resistance. Here, the milling and appearance quality, cooking quality, starch rapid viscosity analyzer (RVA) profile, and nutritional quality of grains of Yuenongsimiao (YNSM), an indica rice variety with high yield, high quality and disease resistance, were determined. YNSM had excellent appearance and quality, with low amylose contents and high gel consistency, and these characteristics exhibited significant correlations with the RVA profile such as hot paste viscosity, cool paste viscosity, setback viscosity, and consistency. Moreover, 5 genes related to length-to-width ratio (LWR) as well as the Wx gene were used to detect the main quality genotype of YNSM. The results showed that YNSM is a semilong-grain rice with a relatively high brown rice rate, milled rice rate and head rice yield and low chalkiness. The results indicated that the LWR and food quality of YNSM might be related to gs3, gw7 and Wxb. This study also reports the quality characteristics of hybrid rice developed using YNSM as a restorer line. The quality characteristics and the genotype for grain quality determined through gene analysis in YNSM may facilitate the breeding of new rice varieties that achieve a balance of grain yield, resistance and quality.

“…However, PC is a typical quantitative trait with a complex genetic structure. Furthermore, it is susceptible to environmental factors, especially nitrogen fertilization in the late growth stages, and therefore a limited number of genes/QTLs regulating PC have been identified from various mutants or mapping populations ( Pradhan et al., 2019 ; Yang et al., 2020 ). For instance, the putative amino acid transporter gene OsAAP6 was shown to be a positive regulator of rice PC ( Peng et al., 2014a ).…”

“…Sugano et al (2020) designed two sgRNAs simultaneously site-directed mutate two genes encoding the major allergens Gly m Bd 28 K and Gly m Bd 30 K in two Japanese soybean varieties and successfully obtained Cas9-free plants with no Gly m Bd 28 Kor Gly m Bd 30 K protein. In rice, grain storage protein seriously affects the quality of rice, especially the eating and cooking quality (ECQ) (Yang et al, 2015;Yang et al, 2020). Generally, the higher rice grain protein content (GPC) will lead to the worse ECQ; thus, the cultivars with good ECQ always are required to have relatively lower GPC, usually less than 7%.…”

“…For example, nitrogen fertilizer as an environmental factor can promote the increase of rice yield and grain protein content. Although the yield and nutritional quality of rice were improved, the increase of grain protein content significantly decreased the rice eating and cooking quality (Yang et al, 2015;Yang et al, 2020). In the breeding process, rice yield and grain quality are often difficult to balance.…”

Good quality of crops has always been the most concerning aspect for breeders and consumers. However, crop quality is a complex trait affected by both the genetic systems and environmental factors, thus, it is difficult to improve through traditional breeding strategies. Recently, the CRISPR/Cas9 genome editing system, enabling efficiently targeted modification, has revolutionized the field of quality improvement in most crops. In this review, we briefly review the various genome editing ability of the CRISPR/Cas9 system, such as gene knockout, knock-in or replacement, base editing, prime editing, and gene expression regulation. In addition, we highlight the advances in crop quality improvement applying the CRISPR/Cas9 system in four main aspects: macronutrients, micronutrients, anti-nutritional factors and others. Finally, the potential challenges and future perspectives of genome editing in crop quality improvement is also discussed.
