“…In addition to promoting rice photosynthesis and inhibiting bacterial virulence, Hpa1 externally applied in the T3ETI approach also activated the SAR and PTI pathways in rice plants. Evidence of induced expression of rice genes involved in SAR or PTI (Figure S11) and phosphorylation of MPKs (Figure 6e), which are essential constituents of the PTI pathway (Chen et al, 2021), was found. However, the activation of SAR and PTI did not require OsPIP1;3.…”

Plant aquaporins are a recently noted biological resource with a great potential to improve crop growth and defense traits. Here, we report the functional modulation of the rice (Oryza sativa) aquaporin OsPIP1;3 to enhance rice photosynthesis and grain production and to control bacterial blight and leaf streak, the most devastating worldwide bacterial diseases in the crop. We characterize OsPIP1;3 as a physiologically relevant CO 2 -transporting facilitator, which supports 30% of rice photosynthesis on average. This role is nullified by interaction of OsPIP1;3 with the bacterial protein Hpa1, an essential component of the Type III translocon that supports translocation of the bacterial Type III effectors PthXo1 and TALi into rice cells to induce leaf blight and streak, respectively. Hpa1 binding shifts OsPIP1;3 from CO 2 transport to effector translocation, aggravates bacterial virulence, and blocks rice photosynthesis. On the contrary, the external application of isolated Hpa1 to rice plants effectively prevents OsPIP1;3 from interaction with Hpa1 secreted by the bacteria that are infecting the plants. Blockage of the OsPIP1;3-Hpa1 interaction reverts OsPIP1;3 from effector translocation to CO 2 transport, abrogates bacterial virulence, and meanwhile induces defense responses in rice. These beneficial effects can combine to enhance photosynthesis by 29-30%, reduce bacterial disease by 58-75%, and increase grain yield by 11-34% in different rice varieties investigated in small-scale field trials conducted during the past years. Our results suggest that crop productivity and immunity can be coordinated by modulating the physiological and pathological functions of a single aquaporin to break the growth-defense tradeoff barrier.

“…The maize ZmMPK5 is induced by various stimuli, involved in defense signaling pathways in various abiotic/biotic stress, confers tolerance to stresses Zhang et al, 2014), and subsequently leads to enhancement of plant growth and yield. Due to the key role of OsMAPK4 in plant growth, grain development (Liu et al, 2018;Chen et al, 2021), and subsequently in GY, the results of the current syntenic analysis suggest the same function for TraesCS7B02G322900 and Zm00001d014658 genes located in OrMQTL_10 interval (Figure 7; Table 5; Supplementary Table 7).…”

Comparative genomics and meta-quantitative trait loci (MQTLs) analysis are important tools for the identification of reliable and stable QTLs and functional genes controlling quantitative traits. We conducted a meta-analysis to identify the most stable QTLs for grain yield (GY), grain quality traits, and micronutrient contents in wheat. A total of 735 QTLs retrieved from 27 independent mapping populations reported in the last 13 years were used for the meta-analysis. The results showed that 449 QTLs were successfully projected onto the genetic consensus map which condensed to 100 MQTLs distributed on wheat chromosomes. This consolidation of MQTLs resulted in a three-fold reduction in the confidence interval (CI) compared with the CI for the initial QTLs. Projection of QTLs revealed that the majority of QTLs and MQTLs were in the non-telomeric regions of chromosomes. The majority of micronutrient MQTLs were located on the A and D genomes. The QTLs of thousand kernel weight (TKW) were frequently associated with QTLs for GY and grain protein content (GPC) with co-localization occurring at 55 and 63%, respectively. The co- localization of QTLs for GY and grain Fe was found to be 52% and for QTLs of grain Fe and Zn, it was found to be 66%. The genomic collinearity within Poaceae allowed us to identify 16 orthologous MQTLs (OrMQTLs) in wheat, rice, and maize. Annotation of promising candidate genes (CGs) located in the genomic intervals of the stable MQTLs indicated that several CGs (e.g., TraesCS2A02G141400, TraesCS3B02G040900, TraesCS4D02G323700, TraesCS3B02G077100, and TraesCS4D02G290900) had effects on micronutrients contents, yield, and yield-related traits. The mapping refinements leading to the identification of these CGs provide an opportunity to understand the genetic mechanisms driving quantitative variation for these traits and apply this information for crop improvement programs.

“…OsPYL5 was also found in the pathway of osa04010 (MAPK signaling pathway). Some mitogen-activated protein kinase (MAPK) cascades play an important role in phytohormone accumulation, signal response, and plant growth and development [ 75 , 76 , 77 ]. OsMAPK cascades participate in some phytohormone responses, such as SA, jasmonic acid (JA) and ABA [ 75 ].…”

Drought and salinity stresses are significant abiotic factors that limit rice yield. Exploring the co-response mechanism to drought and salt stress will be conducive to future rice breeding. A total of 1748 drought and salt co-responsive genes were screened, most of which are enriched in plant hormone signal transduction, protein processing in the endoplasmic reticulum, and the MAPK signaling pathways. We performed gene-coding sequence haplotype (gcHap) network analysis on nine important genes out of the total amount, which showed significant differences between the Xian/indica and Geng/japonica population. These genes were combined with related pathways, resulting in an interesting mechanistic draft called the ‘gcHap-network pathway’. Meanwhile, we collected a lot of drought and salt breeding varieties, especially the introgression lines (ILs) with HHZ as the parent, which contained the above-mentioned nine genes. This might imply that these ILs have the potential to improve the tolerance to drought and salt. In this paper, we focus on the relationship of drought and salt co-response gene gcHaps and their related pathways using a novel angle. The haplotype network will be helpful to explore the desired haplotypes that can be implemented in haplotype-based breeding programs.
