“…This is the case for MSL37 (Os11g0163500) which encodes a positive salt stress transcription factor response by regulating ion transporters, P5CS (Os05g0455500), which causes accumulation of the osmoprotectant proline, the transcription factor SNAC2 (Os01g0884300), which is key in root adaptation, and OsNAP (Os03g0327800), which triggers a stress response mediated by ABA (X. Chen et al, 2014;Lee et al, 2017;Nuñez-Muñoz et al, 2021;Sripinyowanich et al, 2013;Takasaki et al, 2010). For details, see Figure 3 and Table 1.…”

“…Osmoprotection by accumulating molecules such as trehalose or proline is a possible pathway leading to salt tolerance, as proven currently in plants like rice and Arabidopsis (Garg et al, 2002;H. W. Li et al, 2011;Nuñez-Muñoz et al, 2021;Paul et al, 2018). Other individual genes can confer osmoprotection, such as the Na+ transporter SKC1 (Os01g0307500) with a V395L that provides salt tolerance (Jayabalan et al, 2019).…”

Understanding agronomic traits at a genetic level enables the leveraging of this knowledge to produce crops that are more productive and resilient, have better quality and are adjusted for consumer preferences. In the last decade, rice has become a model to validate the function of specific genes, resulting in valuable but scattered information. Here, we aimed to identify particular genes in rice related to traits that can be targeted by different mutation techniques in the breeding of crops. We selected gain of function, misfunction, and specific mutations associated with phenotypes of agronomic interest. The review includes specific trait-related genes involved in domestication, stress, herbicide tolerance, pathogen resistance, grain number/quality/weight, plant structure, nitrogen use, and others. The information presented can be used for rice, other cereals, and orphan crops to achieve a superior and sustainable production in challenging farming conditions.

“…Other transcription factors are critical in stress adaptation, which results in stress sensitivity when knocked out. This is the case for MSL37 (Os11g0163500), P5CS (Os05g0455500), which produces proline accumulation out of external ABA application, the transcription factor SNAC2 (Os01g0884300), which is key in root adaptation, and OsNAP (Os03g0327800), which triggers a stress response mediated by ABA (Takasaki et al, 2010;Sripinyowanich et al, 2013;Chen et al, 2014;Lee et al, 2017;Nuñez-Muñoz et al, 2021).

“…The future of virus delivery of CRISPR/Cas9 to plants for engineering disease, insect and stress resistance Traditional transformation methods with CRISPR/Cas9 constructs were used to target a variety of plant phenotypes, including reduced lodging in elite rice cultivars, drought tolerance in Arabidopsis and maize, and pathogen resistance across numerous plant species (Hu et al 2019b;Nuñez-Muñoz et al 2021;Varanda et al 2021;Wang et al 2019;Zaynab et al 2020). The diverse panel of CRISPR/Cas9 viral systems discussed in this reviewmany just recently published as proof-of-concepthave great potential for developing improved crop varieties with resistance to disease, pests, and abiotic stresses.…”

Agricultural production is hampered by disease, pests, and environmental stresses. To minimize yield loss, it is important to develop crop cultivars with resistance or tolerance to their respective biotic and abiotic constraints. Transformation techniques are not optimized for many species and desirable cultivars may not be amenable to genetic transformation, necessitating inferior cultivar usage and time-consuming introgression through backcrossing to the preferred variety. Overcoming these limitations will greatly facilitate the development of disease, insect, and abiotic stress tolerant crops. One such avenue for rapid crop improvement is the development of viral systems to deliver CRISPR/Cas-based genome editing technology to plants to generate targeted beneficial mutations. Viral delivery of genomic editing constructs can theoretically be applied to span the entire host range of the virus utilized, circumventing the challenges associated with traditional transformation and breeding techniques. Here we explore the types of viruses that have been optimized for CRISPR/Cas9 delivery, the phenotypic outcomes achieved in recent studies, and discuss the future potential of this rapidly advancing technology.
