It was also reported that japonica rice varieties Kamenoo-4 and Joshu tended to be more sensitive to BSM than indica rice varieties IR-8 and IR-26 (Kobayashi et al, 1995), suggesting the possibility that, in addition to the CYP81A6 gene, the CYP72A31 gene is involved in BSM tolerance. To check whether the CYP72A31 gene confers BSM tolerance, the BSM sensitivity in CYP72A31-overexpressing Arabidopsis was checked.…”

Target-site and non-target-site herbicide tolerance are caused by the prevention of herbicide binding to the target enzyme and the reduction to a nonlethal dose of herbicide reaching the target enzyme, respectively. There is little information on the molecular mechanisms involved in non-target-site herbicide tolerance, although it poses the greater threat in the evolution of herbicide-resistant weeds and could potentially be useful for the production of herbicide-tolerant crops because it is often involved in tolerance to multiherbicides. Bispyribac sodium (BS) is an herbicide that inhibits the activity of acetolactate synthase. Rice (Oryza sativa) of the indica variety show BS tolerance, while japonica rice varieties are BS sensitive. Map-based cloning and complementation tests revealed that a novel cytochrome P450 monooxygenase, CYP72A31, is involved in BS tolerance. Interestingly, BS tolerance was correlated with CYP72A31 messenger RNA levels in transgenic plants of rice and Arabidopsis (Arabidopsis thaliana). Moreover, Arabidopsis overexpressing CYP72A31 showed tolerance to bensulfuron-methyl (BSM), which belongs to a different class of acetolactate synthase-inhibiting herbicides, suggesting that CYP72A31 can metabolize BS and BSM to a compound with reduced phytotoxicity. On the other hand, we showed that the cytochrome P450 monooxygenase CYP81A6, which has been reported to confer BSM tolerance, is barely involved, if at all, in BS tolerance, suggesting that the CYP72A31 enzyme has different herbicide specificities compared with CYP81A6. Thus, the CYP72A31 gene is a potentially useful genetic resource in the fields of weed control, herbicide development, and molecular breeding in a broad range of crop species.

“…The low phytotoxicity, long medicinal effect period, and low mobility of dimepiperate were first reported by Japan’s Mitsubishi Chemical Co., Ltd. in 1976, and it was used as a highly selective herbicide to control weeds in crops, such as rice. In 1986, dimepiperate was reported to alleviate the phytotoxicity of the sulfonylurea herbicide bensulfuron in paddy fields. , Piperazine was used as the starting material, and dimepiperate was directly obtained by a one-step condensation reaction (Scheme ).…”

Detoxification plays an important role in herbicide action. Herbicide safeners selectively protect crops from herbicide injury without reducing the herbicidal efficiency against the target weeds. With the large-scale use of herbicides, herbicide safeners have been widely used in sorghum, wheat, rice, corn, and other crops. In recent years, an increasing number of unexpected new herbicide safeners have been designed. The varieties, structural characteristics, uses, and synthetic routes of commercial herbicide safeners are reviewed in this paper. The design ideas and structural characteristics of novel herbicide safeners are summarized, which provide a basis for the design of bioactive molecules as new herbicide safeners in the future.

“…In addition, a wide range of herbicide susceptibility exists in cultivated rice, e.g. indica vs. japonica to acetolactate synthase (ALS) inhibitors (Kobayashi, Yogo and Sugiyama, 1995), and whether having functional his1 gene which confers resistance to 4-HPPD inhibitors (Maeda et al, 2019). Moreover, herbicide-resistant rice cultivars are more frequently used as one of the management options in the United States and Latin America (Sudianto et al, 2013).…”

From their first commercialisation in the mid-1990s, genetically engineered crops (also known as "transgenic" or "genetically modified" plants) have been approved for commercial release in an increasing number of countries, for planting, entering in the composition of foods and feeds, or use in industrial processing. The majority of these productions are for soybean, maize, cotton and rapeseed (canola) bearing pest resistance and herbicide tolerance traits, aiming to improve yields and reduce the costs of production. Other transgenic crops that are increasingly grown to date comprise lucerne (alfalfa), sugar beet, sugarcane, papaya, safflower, potato, eggplant, as well as pumpkin, apple and pineapple in smaller areas. Other traits are increasingly introduced in engineered plants, adapting them to biotic or abiotic stress, such as resistance to drought or tolerance to salt in the growing environment, or changing a characteristic, e.g. modified oil content, reduced lignin content, non-browning or nutritional quality (biofortification). Thus, transgenic crops, where adopted and available on the market, enlarge possibilities for farmers, industry and consumers. They can play a part in addressing global concerns such as the rising need for food and feed in the growing population context or the necessary adaptation of agriculture for better resilience to climate change.Modern biotechnologies are applied to plants (crops, flowers and trees) but also animals and micro-organisms. The safety of the resulting genetically engineered organisms, when released in the environment for their use in agriculture, forestry, fishery, the food and feed industry, biofuel production or other applications, represents a challenging issue. A scientifically sound approach to their risk assessment should inform biosafety regulators and support national decisions regarding their possible market release. Genetically engineered products are rigorously assessed by their developers during their elaboration and by governments when ready for commercial use, to ensure high safety standards for the environment, human food and animal feed. Such assessments are considered essential for healthy and sustainable agriculture, industry and trade.In 2019, according to the annual report of the International Service for the Acquisition of Agri-biotech Applications, the five main producers of genetically engineered crops were the United States, Brazil, Argentina, Canada and India (listed by decreasing area) covering a combined 170 million hectares representing more than 90% of the global transgenic crop area. Among the 29 countries having grown genetically engineered crops in that year, 9 of them were OECD countries, listed by decreasing area as follows: the
