“…'Green super rice' has become the goal of rice breeding since the beginning of this century and high yield with good quality is the main pursuit of rice breeders (Zhang 2007). With the improvement of living standards and health care consciousness, people are paying increasing attention to the healthy substances in food (Zhao et al 2020;Zhou et al 2019). Reducing the anthocyanin content in green tissues will enhance the photosynthesis e ciency and further increase rice yield.…”

Anthocyanins are major subclasses of flavonoids, which have diverse biological functions and benefit human health. In Oryza sativa, organs exhibit various color due to the accumulation of anthocyanins. On the other hand, anthocyanins biosynthesis is a domestication related trait. Revealing the genetic basis of anthocyanins biosynthesis in rice is not only important for the engineering of anthocyanins, but also helpful for understanding the evolutionary story of Oryza sativa. Here we summarize the recent progresses in rice anthocyanins biosynthesis, including the anthocyanins biosynthetic pathway, the genes that participate in anthocyanins biosynthesis, the cloning of anthocyanins related genes and the domestication process of rice anthocyanins. Possible applications of rice anthocyanin biosynthesis genes in rice breeding and the remaining unknown mechanism of anthocyanins accumulation in stigma, apiculus and awn are also discussed.

“…Rice has become the major staple food for humans for perhaps three main reasons: (1) rice grains have good cooking quality, excellent taste, and are easy to digest (Tian et al, 2009;Saikrishna et al, 2018;Ziegler et al, 2018;Bao, 2019;Mestres et al, 2019;Zhou et al, 2020); (2) very few people exhibit allergic reactions to rice grains, and rice is thus often regarded as hypoallergenic (Zhu et al, 2015); and (3) rice has high productivity per unit area, and, in some rice-cultivating zones, up to three/four cultures of rice can be produced annually (Khush, 2003). Thus, paddy rice has come to meet the human food demand and to dominate as a staple food.…”

There is an urgent demand for low-arsenic rice in the global market, particularly for consumption by small children. Soils in Uppsala, Sweden, contain low concentrations of arsenic (As). We hypothesize that if certain japonica paddy rice varieties can adapt to the cold climate and long day length in Uppsala and produce normal grains, such a variety could be used for organic production of low-arsenic rice for safe rice consumption. A japonica paddy rice variety, "Heijing 5," can be cultivated in Uppsala, Sweden, after several years' adaptation, provided that the rice plants are kept under a simple plastic cover when the temperature is below 10 • C. Uppsala-adapted "Heijing 5" has a low concentration of 0.1 mg per kg and high protein content of 12.6% per dry weight in brown rice grain, meaning that it thus complies with all dietary requirements determined by the EU and other countries for small children. The high protein content is particularly good for small children in terms of nutrition. Theoretically, Uppsala-adapted "Heijing 5" can produce a yield of around 5100 kg per ha, and it has a potential for organic production. In addition, we speculate that cultivation of paddy rice can remove nitrogen and phosphorus from Swedish river water and reduce nutrient loads to the Baltic Sea and associated algae blooms.

“…To meet the needs of producers and consumers, researchers have to understand the molecular genetic basis that determines rice grain quality, and breeders and seed companies have to develop varieties with high yield, good quality, and health benefits. The review by Zhou et al (2019) summarized consumer demand for rice quality, common and regional characteristics of good-quality rice, classification and importance of rice quality, and increasing health awareness of consumers. They also provided a comprehensive overview on the functional genes for various grain quality traits in rice and the genetic improvement practices of grain quality, and then discussed challenges and prospects of rice grain quality improvement.…”

Rice is not only a staple food crop worldwide but also a key model cereal crop for genomic and plant science research. Rice has made great progress in the last three decades in functional genomics and genetic improvement, playing a leading role among crops. Aiming to realize less pesticide, less chemical fertilizer, water saving and drought resistance, and acceptable grain quality and high yield in rice production, Green Super Rice (GSR), proposed by Prof. Qifa Zhang (Huazhong Agricultural University, China), provides a promising strategy for sustainable agriculture and will be boosted by the breakthrough and systematical achievements of rice functional genomics. Thus, the Editor-in-Chief of Molecular Breeding, Prof. Qifa Zhang, invited Prof. Lizhong Xiong (Huazhong Agricultural University, China) and Prof. Yusaku Uga (National Agriculture and Food Research Organization, Japan) as two guest editors to host the special issue named "Rice Functional
