“…Recently, Zhang and colleagues reported that the anac044 mutant exhibits insensitivity to Pi deficiency by elevating Pi reutilization of the cell wall (Zhang et al., 2021), which functions as an important Pi pool when plants encounter Pi deficiency (Wu et al., 2019; Zhu et al., 2015). In the anac044 mutant, there is more soluble Pi available through its remobilization from the cell wall.…”

SUMMARY Being sessile organisms, plants are ubiquitously exposed to stresses that can affect the DNA replication process or cause DNA damage. To cope with these problems, plants utilize DNA damage response (DDR) pathways, consisting of both highly conserved and plant‐specific elements. As a part of this DDR, cell cycle checkpoint control mechanisms either pause the cell cycle, to allow DNA repair, or lead cells into differentiation or programmed cell death, to prevent the transmission of DNA errors in the organism through mitosis or to its offspring via meiosis. The two major DDR cell cycle checkpoints control either the replication process or the G2/M transition. The latter is largely overseen by the plant‐specific SOG1 transcription factor, which drives the activity of cyclin‐dependent kinase inhibitors and MYB3R proteins, which are rate limiting for the G2/M transition. By contrast, the replication checkpoint is controlled by different players, including the conserved kinase WEE1 and likely the transcriptional repressor RBR1. These checkpoint mechanisms are called upon during developmental processes, in retrograde signaling pathways, and in response to biotic and abiotic stresses, including metal toxicity, cold, salinity, and phosphate deficiency. Additionally, the recent expansion of research from Arabidopsis to other model plants has revealed species‐specific aspects of the DDR. Overall, it is becoming evidently clear that the DNA damage checkpoint mechanisms represent an important aspect of the adaptation of plants to a changing environment, hence gaining more knowledge about this topic might be helpful to increase the resilience of plants to climate change.

“…Overexpressing GmPAP1-like enhanced Arabidopsis growth and P content when dNTP was supplied as the sole external P source [ 25 ]. In addition, some DAPs functions in cell wall carbohydrate metabolism were also identified to be up-regulated in Arabidopsis suspension cells or root cell walls under P-deficient conditions, such as polygalacturonase (PG) and xyloglucan endotransglycosylase (XET), which was suggested to release cell wall-bound Pi under low-P conditions [ 25 , 112 , 114 ]. Additionally, since changes in polysaccharides in cell wall metabolism could influence the rhizosphere size, which was suggested to be positively correlated with P accumulation in plants, DAPs related to cell wall metabolism might affect plant P efficiency partially through changing rhizosphere size [ 115 ].…”

Phosphorus (P) is an essential nutrient for plant growth. In recent decades, the application of phosphate (Pi) fertilizers has contributed to significant increases in crop yields all over the world. However, low efficiency of P utilization in crops leads to intensive application of Pi fertilizers, which consequently stimulates environmental pollution and exhaustion of P mineral resources. Therefore, in order to strengthen the sustainable development of agriculture, understandings of molecular mechanisms underlying P efficiency in plants are required to develop cultivars with high P utilization efficiency. Recently, a plant Pi-signaling network was established through forward and reverse genetic analysis, with the aid of the application of genomics, transcriptomics, proteomics, metabolomics, and ionomics. Among these, proteomics provides a powerful tool to investigate mechanisms underlying plant responses to Pi availability at the protein level. In this review, we summarize the recent progress of proteomic analysis in the identification of differential proteins that play roles in Pi acquisition, translocation, assimilation, and reutilization in plants. These findings could provide insights into molecular mechanisms underlying Pi acquisition and utilization efficiency, and offer new strategies in genetically engineering cultivars with high P utilization efficiency.

“…We can also see a slight difference in the expression of the berberine bridge enzyme (BBE) between heat and drought. It was reported that BBE is highly important in plant adaptation to phosphorus deficiency [58], which is more related to drought [59].…”

Heat and drought are among the leading environmental stresses which have a major impact on plant development. In our research, identification and characterization of differentially expressed genes (DEGs) regulating the response of wheat to drought, heat and combined stress was carried out. We analyzed data from the Gene Expression Omnibus database (GEO) microarrays containing 24 samples of wheat, which were categorized by different treatments (control: ctrl, drought: D, heat: H, and mixed: HD). Significant DEGs were examined for gene annotation, gene ontology, co-expression, protein-protein interaction (PPI) and their heterogeneity and consistency through drought, heat and combined stress was also studied. Genes such as gyrB, C6orf132 homolog, PYR1 were highly associated with wheat response to drought with P-value (-log10) of 9.3, 7.3, 6.4, and logFC of -3.9, 2.0, 1.6, respectively. DEGs associated with drought tolerance were highly related to the protein domains of lipid-transfer (LTP). Wheat response to heat stress was strongly associated with genes such as RuBisCO activase B, small heat shock, LTP3, YLS3, At2g33490, PETH with p-values (-log10) ranging from 9.3 to 12.3. In addition, a relatively high number of protein interactions involved the SDH, PEPCK, and G6PD genes under heat stress.
