“…Weeds compete with crop plants for nutrients, sunlight, and living space, disrupt airflow, intercept light, and promote pests and diseases in the field. Moreover, parasitic weeds absorb nutrients from crop plants, thereby decreasing the yield and quality of those crops [122,123]. Deploying weed management practices is therefore important [124][125][126].…”

The clustered regularly interspaced short palindromic repeats (CRISPR)/associated protein 9 system (Cas9) has been used at length to optimize multiple aspects of germplasm resources. However, large-scale genomic research has indicated that novel variations in crop plants are attributed to single-nucleotide polymorphisms (SNPs). Therefore, substituting single bases into a plant genome may produce desirable traits. Gene editing by CRISPR/Cas9 techniques frequently results in insertions–deletions (indels). Base editing allows precise single-nucleotide changes in the genome in the absence of double-strand breaks (DSBs) and donor repair templates (DRTs). Therefore, BEs have provided a new way of thinking about genome editing, and base editing techniques are currently being utilized to edit the genomes of many different organisms. As traditional breeding techniques and modern molecular breeding technologies complement each other, various genome editing technologies have emerged. How to realize the greater potential of BE applications is the question we need to consider. Here, we explain various base editings such as CBEs, ABEs, and CGBEs. In addition, the latest applications of base editing technologies in agriculture are summarized, including crop yield, quality, disease, and herbicide resistance. Finally, the challenges and future prospects of base editing technologies are presented. The aim is to provide a comprehensive overview of the application of BE in crop breeding to further improve BE and make the most of its value.

“…Modern pest management has been highly dependent on the science of pesticides. The challenges of pest management are enormous, and as pointed out by Edwards and Hannah [18] the potential input from the wider plant science community is largely unrecognized. Reddy and James [19] claim that weed science has been slow to "catch up" with progress toward precision agriculture that has been made in irrigation and fertilizer management.…”

Agriculture’s Moral Dilemmas and the Need for Agroecology

Those engaged in agriculture possess a definite but unexamined moral confidence or certainty about the correctness of what they do. The basis of the moral confidence is not obvious to those who have it, or to the public. In fact, the moral confidence that pervades agriculture is potentially harmful because it is unexamined. It is necessary that those engaged in agriculture analyze what it is about agriculture in society that favors, inhibits, or limits agriculture. All should strive to nourish and strengthen the aspects of agriculture that are beneficial and change those that are not. To do this all must be confident to study ourselves, our institutions, and be dedicated to the task of modifying the values and goals of both.

“…Weed control is and has always been a major challenge for agriculture worldwide. Among all the implemented methods to minimise or avoid the many problems derived from weeds, herbicides continue being the most widely used tools for weed control (Edwards and Hannah, 2014). Herbicides inhibit specific molecular target sites within plant biological pathways and processes, and are classified into groups according to their target.…”

Role of oxidative stress in the physiology of sensitive and resistant Amaranthus palmeri populations treated with herbicides inhibiting acetolactate synthase

et al. 2023

The aim of the present study was to elucidate the role of oxidative stress in the mode of action of acetolactate synthase (ALS) inhibiting herbicides. Two populations of Amaranthus palmeri S. Watson from Spain (sensitive and resistant to nicosulfuron, due to mutated ALS) were grown hydroponically and treated with different rates of the ALS inhibitor nicosulfuron (one time and three times the field recommended rate). Seven days later, various oxidative stress markers were measured in the leaves: H2O2, MDA, ascorbate and glutathione contents, antioxidant enzyme activities and gene expression levels. Under control conditions, most of the analysed parameters were very similar between sensitive and resistant plants, meaning that resistance is not accompanied by a different basal oxidative metabolism. Nicosulfuron-treated sensitive plants died after a few weeks, while the resistant ones survived, independently of the rate. Seven days after herbicide application, the sensitive plants that had received the highest nicosulfuron rate showed an increase in H2O2 content, lipid peroxidation and antioxidant enzymatic activities, while resistant plants did not show these responses, meaning that oxidative stress is linked to ALS inhibition. A supralethal nicosulfuron rate was needed to induce a significant oxidative stress response in the sensitive population, providing evidence that the lethality elicited by ALS inhibitors is not entirely dependent on oxidative stress.
