Abstract ：
White lupin exhibits remarkable adaptability to phosphorus (P)-deficient soil through the development of cluster roots (CR), thereby enhancing P use sufficiency. Despite its crucial role, the underlying mechanism governing CR formation remains elusive. Here, we reveal an elevated DNA methylation level through whole-genome bisulfite sequencing in CR in response to P deficiency, particularly in gene and flanking regions, suggesting a responsive epigenetic mechanism. To further investigate the potential involvement of epigenetic remodelling, we treated lupin plants with the DNA methyltransferase (DNMT) inhibitor 5-azacytidine, which led to a disruption of total DNMT activity and impaired CR formation under phosphorus-deficient conditions. Integrated analysis of methylome and RNA-Seq highlights the methylation of CAFFEIC ACID O-METHYLTRANSFERASE 1 (COMT1), a key enzyme in melatonin synthesis, as pivotal for promoting CR formation in white lupin. Functional validation through overexpression or gene silencing of LaCOMT1 in transgenic lupin roots confirms the positive impact of LaCOMT1 on CR formation. Furthermore, melatonin application directly increases CR numbers, indicating the role of methylation-activated LaCOMT1 in promoting CR formation via melatonin synthesis. Those findings provide insights into the epigenomic landscape of white lupin, establishing a direct genetic link between epigenetic mechanisms and P-deficiency-induced CR formation.

Abstract ：
Hydrotropism is an important adaptation of plant roots to the uneven distribution of water, with current research mainly focused on Arabidopsis thaliana. To examine hydrotropism in tomato (Solanum lycopersicum) primary roots, we used RNA sequencing to determine gene expression of root tips (apical 5 mm) on dry and wet sides of hydrostimulated roots grown on agar plates. Hydrostimulation enhances cell division and expansion on the dry side compared with the wet side of the root tip. In hydrostimulated roots, the abscisic acid (ABA) biosynthesis gene ABA4 was induced more on the dry than the wet side of root tips. The ABA biosynthesis inhibitor Fluridone and the ABA-deficient mutant notabilis (not) significantly decreased hydrotropic curvature. Wild-type, but not the ABA biosynthesis mutant not, root tips showed asymmetric H+ efflux, with greater efflux on the dry than on the wet side of root tips. Thus, ABA mediates asymmetric H(+ )efflux, allowing the root to bend towards the wet side to take up more water.

Abstract ：
Aims The gene qPE9-1, which encodes the G protein gamma subunit, is important for nitrogen (N) use in rice and in regulating rice photosynthesis under elevated CO2 (eCO(2)). However, under a changing climate, the qPE9-1 response to combined increasing atmospheric CO2 (aCO(2)) and soil N availability is unclear. Therefore, we investigated the regulative roles of qPE9-1 in rice N use under eCO(2). Methods Wild-type (WT) and qPE9-1 RNAi rice plants were exposed to low (LN) and high (HN) N treatments under aCO(2) (400 ppm) and eCO(2) (800 ppm) in the growth chamber and the field Open-Top Chamber (OTC). Rice growth, net photosynthetic rate, and N uptake were determined in the growth chamber. Then, the OTC was used to evaluate to the combined impacts of eCO(2) and N on rice yield. Results Under HN conditions, the dry weight and net photosynthesis rate of WT plants was significantly increased under eCO(2) compared with aCO(2); however, there was no significant difference in the qPE9-1 RNAi lines. The CO2 and N levels had relatively minor effects on the carbon concentration of all plants. Regardless of the CO2 concentration, the N concentrations in the roots and leaves of all plants were significantly reduced under LN treatment compared with HN. Under LN conditions, eCO(2) enhanced the N content of WT plants, but had no significant effects on the RNAi lines. The grain yield of WT plants was also significantly increased by eCO(2) under HN treatment in the field OTC, whereas the RNAi lines were not affected. Conclusion The G protein gamma subunit qPE9-1 is involved in N uptake under elevated CO2; however, this response is affected by N levels. These findings provide useful information on efficient N management for adapting to the future CO2-enriched environment.

Abstract ：
Beneficial root-associated rhizospheric microbes play a key role in maintaining host plant growth and can potentially allow drought-resilient crop production. The complex interaction of root-associated microbes mainly depends on soil type, plant genotype, and soil moisture. However, drought is the most devastating environmental stress that strongly reduces soil biota and can restrict plant growth and yield. In this review, we discussed our mechanistic understanding of drought and microbial response traits. Additionally, we highlighted the role of beneficial microbes and plant-derived metabolites in alleviating drought stress and improving crop growth. We proposed that future research might focus on evaluating the dynamics of root-beneficial microbes under field drought conditions. The integrative use of ecology, microbial, and molecular approaches may serve as a promising strategy to produce more drought-resilient and sustainable crops.

Abstract ：
Phosphorus (P) deficiency heterogeneously affected plant nutritional status and physiological performance, ultimately leading to a severe yield reduction. A few putative long non-coding RNAs (lncRNAs) responding to P-starvation in the model crops Arabidopsis thaliana and Oryza sativa have been characterized. White lupin (Lupinus albus) is of prime importance, and is a legume with increasing agronomic value as a protein crop as it exhibits extreme tolerance to nutrient deficiency, particularly P deficiency. Despite its adapted nature to P deficiency, nothing is known about low P-induced lncRNAs in white lupin roots. To address this issue, we identified 39,840 mRNA and 2028 lncRNAs in the eight developmental stages of white lupin root (S0-S7 and lateral root, LR) grown under P deficiency. From these 2028 lncRNAs, 1564 were intergenic and 464 natural antisense intergenic transcript (NAT) lncRNAs. We further predicted six potential targets of miRNAs with twelve lncRNAs, which may regulate P-deficiency-related processes. Moreover, the weighted gene co-expression network analysis (WGCNA) revealed seven modules that were correlated with the expression pattern of lncRNAs. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed 606 GO terms and 27 different pathways including signal transduction, energy synthesis, detoxification, and Pi transport. In addition, we screened 13 putative lncRNAs that showed a distinct expression pattern in each root, indicating their role in the P deficiency regulatory network. Therefore, white lupin may be a reference legume to characterize P-deficiency-responsive novel lncRNAs, which would highlight the role of lncRNAs in the regulation of plant responses to P deficiency.

Abstract ：
Abscisic acid (ABA) plays an important role in plant adaptation to water deficits, but its role in regulating root growth (primary root elongation and lateral root number) during different drought-phases remains unclear. Here, we exposed wild-type (WT) and ABA-deficient (not) tomato plants to three continuous drought-phases (moderate drying: day 0-21; severe drying: day 22-47 and re-watering: day 48-51). It was found that WT increased primary root growth during moderate drying; maintained more lateral roots, and greater primary root and total root length under severe drying; and produced more roots after re-watering. After RNA-Seq analysis, we found that the auxin-related genes in root showed different expression patterns between WT and not under drying or re-watering. Further, exogenous supply of IAA partially recovered the root growth of ABA-deficient not plants under three continuous drought-phases. Our results suggested that ABA regulation of tomato root growth during soil drying and recovery can involve auxin response.

Abstract ：
Abscisic acid (ABA) is a critical hormone for plant survival upon water stress. In this study, a large-scale mutants of Arabidopsis ecotype Columbia-0 (Col-0) by ethyl methanesulfonate (EMS)-mutagenesis were generated, and an improved root elongation under water-stress 1 (irew1) mutant showing significantly enhanced root growth was isolated upon a water potential gradient assay. Then, irew1 and ABA-related mutants in Arabidopsis or tomato plants were observed under water potential gradient assay or water-deficient condition. ABA pathway, Ca2+ response and primary root (PR) elongation rate were monitored in addition to DNA- and RNA-Seq analyses. We found that based on phenotyping and transcriptional analyses, irew1 exhibited the enhanced PR growth, ABA and Ca2+ responses compared to wild-type subjected to water stress. Interestingly, exogenous Ca2+ application enhanced PR growth of irew1, ABA-biosynthesis deficient mutants in Arabidopsis and tomato plants in response to water potential gradients or water-deficient condition. In combination with other ABA-related mutants and pharmacological study, our results suggest that ABA is required for root elongation associated with Ca2+ influx in response to water stress.

Abstract ：
Phosphorus (P) deficiency largely restricts plant growth and lead to severe yield losses. Therefore, identification of novel root traits to improve P uptake is needed to circumvent yield losses. White lupin (Lupinus albus) is a legume crop that develops cluster roots and has the high phosphorus use efficiency in low P soils. We aimed to investigate the association between cluster roots (CR) rhizosheath formation and P uptake in white lupin. Rhizosheath formation and P concentration were evaluated under four soil treatments. CR increased up to 2.5-fold of overall plant dry weight under SD-P compared to WW + P (control), partly attributable to variations in CR development. Our data showed that SD-P significantly increase rhizosheath weight in white lupin. Among the root segments, MCR showed improved P accumulation in the root which is associated with increased MCR rhizosheath weight. Additionally, a positive correlation was observed between MCR rhizosheath weight and P uptake. Moreover, high sucrose content was recorded in MCR, which may contribute in CR growth under SD-P. Expression analysis of genes related to sucrose accumulation (LaSUC1, LaSUC5, and LaSUC9) and phosphorus uptake (LaSPX3, LaPHO1, and LaPHT1) exhibited peaked expression in MCR under SD-P. This indicate that root sucrose status may facilitate P uptake under P starvation. Together, the ability to enhance P uptake of white lupin is largely associated with MCR rhizosheath under SD-P. Our results showed that gene expression modulation of CR forming plant species, demonstrating that these novel root structures may play crucial role in P acquisition from the soil. Our findings could be implicated for developing P and water efficient crop via CR development in sustainable agriculture.
