In plant models such as Arabidopsis thaliana, phosphatidic acid (PA), a key molecule of lipid signaling, was shown not only to be involved in stress responses, but also in plant development and nutrition. In this article, we highlight lipid signaling existing in crop species. Based on open access databases, we update the list of sequences encoding phospholipases D, phosphoinositide-dependent phospholipases C, and diacylglycerol-kinases, enzymes that lead to the production of PA. We show that structural features of these enzymes from model plants are conserved in equivalent proteins from selected crop species. We then present an in-depth discussion of the structural characteristics of these proteins before focusing on PA binding proteins. For the purpose of this article, we consider RESPIRATORY BURST OXIDASE HOMOLOGUEs (RBOHs), the most documented PA target proteins. Finally, we present pioneering experiments that show, by different approaches such as monitoring of gene expression, use of pharmacological agents, ectopic over-expression of genes, and the creation of silenced mutants, that lipid signaling plays major roles in crop species. Finally, we present major open questions that require attention since we have only a perception of the peak of the iceberg when it comes to the exciting field of phospholipid signaling in plants.

“…Previous studies have shown that 14-3-3 proteins have a significant impact on stress resistance ( Roberts, 2003 ). In rice, OsGF14b improves salt tolerance by interacting with OsPCL1, inhibiting its ubiquitination for protection from degradation, and promoting its activity and stability ( Wang et al., 2023 ). Overexpression of both heterologous PvGF14a and PvGF14g in transgenic Arabidopsis under salt stress reduces seed germination and fresh seedling weight, suggesting the involvement of these genes in the negative regulation of salt tolerance in seedlings ( Li et al., 2018 ).…”

“…In Arabidopsis , it was found that 14-3-3 proteins can respond to salt stress by regulating the activity of antioxidant enzymes ( Visconti et al., 2019 ; Wang et al., 2019 ). In general, 14-3-3 proteins can interact with many TFs to regulate salt stress resistance in plants ( Chang et al., 2019 ; Wang et al., 2023 ). For example, 14-3-3 proteins can interact with GmMYB173 to regulate antioxidant enzyme activity and hydrogen peroxide scavenging in soybean to regulate salt resistance ( Pi et al., 2018 ).…”

The apple 14-3-3 gene MdGRF6 negatively regulates salt tolerance

The 14-3-3 (GRF, general regulatory factor) regulatory proteins are highly conserved and are widely distributed throughout the eukaryotes. They are involved in the growth and development of organisms via target protein interactions. Although many plant 14-3-3 proteins were identified in response to stresses, little is known about their involvement in salt tolerance in apples. In our study, nineteen apple 14-3-3 proteins were cloned and identified. The transcript levels of Md14-3-3 genes were either up or down-regulated in response to salinity treatments. Specifically, the transcript level of MdGRF6 (a member of the Md14-3-3 genes family) decreased due to salt stress treatment. The phenotypes of transgenic tobacco lines and wild-type (WT) did not affect plant growth under normal conditions. However, the germination rate and salt tolerance of transgenic tobacco was lower compared to the WT. Transgenic tobacco demonstrated decreased salt tolerance. The transgenic apple calli overexpressing MdGRF6 exhibited greater sensitivity to salt stress compared to the WT plants, whereas the MdGRF6-RNAi transgenic apple calli improved salt stress tolerance. Moreover, the salt stress-related genes (MdSOS2, MdSOS3, MdNHX1, MdATK2/3, MdCBL-1, MdMYB46, MdWRKY30, and MdHB-7) were more strongly down-regulated in MdGRF6-OE transgenic apple calli lines than in the WT when subjected to salt stress treatment. Taken together, these results provide new insights into the roles of 14-3-3 protein MdGRF6 in modulating salt responses in plants.

“…Although a recent review summarized advances in stress sensing and signalling, functional adaptation, and salinity tolerance breeding (T. Chen et al, 2021), understanding the complexity of salinity tolerance mechanisms in rice is still limited, and real salt‐tolerant rice varieties are not yet available. Wang et al (2023) reported, in this issue, the new functions of a 14‐3‐3 protein, OsGF14b, in regulating stability and function of a previously known protein essential for rice salt tolerance, phospholipase C (OsPLC1), thus improving rice salt tolerance (N. Wang et al, 2023). Although effects of OsDG14b on grain yield and the potential of its incorporation into commercial germplasm were not investigated, this study will stimulate interests in 14‐3‐3 proteins.…”

A key to achieve the goals put forward in the UN's 2030 Agenda for Sustainable Development, it will need transformative change to our agrifood systems. We must mount to the global challenge to achieve food security in a sustainable manner in the context of climate change, population growth, urbanization, and depletion of natural resources. Rice is one of the major staple cereal crops that has contributed, is contributing, and will still contribute to the global food security. To date, rice yield has held pace with increasing demands, due to advances in both fundamental and biological studies, as well as genomic and molecular breeding practices. However, future rice production depends largely on the planting of resilient cultivars that can acclimate and adapt to changing environmental conditions. This Special Issue highlight with reviews and original research articles the exciting and growing field of rice‐environment interactions that could benefit future rice breeding. We also outline open questions and propose future directions of 2050 rice research, calling for more attentions to develop environment‐resilient rice especially hybrid rice, upland rice and perennial rice.
