As an important regulator of rice crown root development, WOX11 is essential for crown root formation and its transcript level is positively correlated with crown root biomass. However, how WOX11 is regulated during crown root primordium emergence and outgrowth still remains unknown. In this study, variations of the WOX11 genomic sequence were analyzed, and the highest genetic diversity was found within its promoter, which contained a non-canonical miniature inverted-repeat transposable element (ncMITE) sequence. Analysis of the WOX11 promoter-driven reporter gene GUS (β-glucuronidase) transgenic plants pWOX11(ncMITE+):GUS and pWOX11(ncMITE-):GUS uncovered higher GUS expression levels in crown roots of pWOX11(ncMITE+):GUS plants. Furthermore, pWOX11(ncMITE+):WOX11-FLAG in wox11 background could complement the crown root number and length compared to those of the wild type, while pWOX11(ncMITE-):WOX11-FLAG could not. These results suggested that the ncMITE was positively associated with WOX11 transcripts in rice crown roots. In addition, DNA methylation nearby the ncMITE region attenuated the activation effect of the ncMITE on WOX11 expression, which might also be the cause conferred to the root-specific expression of WOX11. This work provides novel insight into WOX11 expression regulation and reveals a promising target for genetic improvement of root architecture in rice.</p>","PeriodicalId":502140,"journal":{"name":"Plant & Cell Physiology","volume":" ","pages":"1052-1062"},"PeriodicalIF":4.9,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40139084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Populus tremula x alba, PtaSUT4 encodes a tonoplast sucrose-proton symporter, whose downregulation by chronic mild drought or transgenic manipulation is known to increase leaf sucrose and turgor. While this may constitute a single drought tolerance mechanism, we now report that other adjustments which can occur during a worsening water deficit are damped when PtaSUT4 is constitutively downregulated. Specifically, we report that starch use and leaf relative water content (RWC) dynamics were compromised when plants with constitutively downregulated PtaSUT4 were subjected to a water deficit. Leaf RWC decreased more in wild-type and vector control lines than in transgenic PtaSUT4-RNAi (RNA-interference) or CRISPR (clustered regularly interspersed short palindromic repeats) knockout (KO) lines. The control line RWC decrease was accompanied by increased PtaSUT4 transcript levels and a mobilization of sucrose from the mesophyll-enriched leaf lamina into the midvein. The findings suggest that changes in SUT4 expression can increase turgor or decrease RWC as different tolerance mechanisms to reduced water availability. Evidence is presented that PtaSUT4-mediated sucrose partitioning between the vacuole and the cytosol is important not only for overall sucrose abundance and turgor, but also for reactive oxygen species (ROS) and antioxidant dynamics. Interestingly, the reduced capacity for accelerated starch breakdown under worsening water-deficit conditions was correlated with reduced ROS in the RNAi and KO lines. A role for PtaSUT4 in the orchestration of ROS, antioxidant, starch utilization and RWC dynamics during water stress and its importance in trees especially, with their high hydraulic resistances, is considered.</p>","PeriodicalId":502140,"journal":{"name":"Plant & Cell Physiology","volume":" ","pages":"1117-1129"},"PeriodicalIF":4.9,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9381566/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40120158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ROS stimulate stomatal closure by inhibiting blue light (BL)-dependent stomatal opening under diverse stresses in the daytime. However, the stomatal opening inhibition mechanism by ROS remains unclear. In this study, we aimed to examine the impact of reactive carbonyl species (RCS), lipid peroxidation products generated by ROS, on BL signaling in guard cells. Application of RCS, such as acrolein and 4-hydroxy-(E)-2-nonenal (HNE), inhibited BL-dependent stomatal opening in the epidermis of Arabidopsis thaliana. Acrolein also inhibited H+ pumping and the plasma membrane H+-ATPase phosphorylation in response to BL. However, acrolein did not inhibit BL-dependent autophosphorylation of phototropins and the phosphorylation of BLUE LIGHT SIGNALING1 (BLUS1). Similarly, acrolein affected neither the kinase activity of BLUS1 nor the phosphatase activity of protein phosphatase 1, a positive regulator of BL signaling. However, acrolein inhibited fusicoccin-dependent phosphorylation of H+-ATPase and stomatal opening. Furthermore, carnosine, an RCS scavenger, partially alleviated the abscisic-acid- and hydrogen-peroxide-induced inhibition of BL-dependent stomatal opening.

Rapeseed (Brassica napus L.) is an important oil-crop species with very low nitrogen-use efficiency (NUE), the regulatory mechanism of which was elusive due to the vastness and complexity of the rapeseed genome. In this study, a comparative transcriptomic analysis was performed to investigate the differential signatures of nitrogen-starved rapeseed in responses to NO3- and NH4+ treatments and to identify the key genes regulating rapeseed NUE. The two nitrogen sources differentially affected the shoot and root transcriptome profiles, including those of genome-wide nitrogen transporter and transcription factor (TF)-related genes. Differential expression profiling showed that BnaA6.NRT2;1 and BnaA7.AMT1;3 might be the core transporters responsible for efficient NO3- and NH4+ uptake, respectively; the TF genes responsive to inorganic nitrogen, specifically responding to NO3-, and specifically responsive to NH4+ were also identified. The genes which were commonly and most significantly affected by both NO3- and NH4+ treatments were related to glutamine metabolism. Among the glutamine synthetase (GS) family genes, we found BnaA2.Gln1;4, significantly responsive to low-nitrogen conditions and showed higher transcription abundance and GS activity in the leaf veins, flower sepals, root cortex and stele, silique petiole and stem tissues.

The heterologous overexpression of BnaA2.Gln1;4 in Arabidopsis increased plant biomass, NUE, GS activity and total amino acid concentrations under both sufficient- and low-nitrogen conditions.

Although the mechanisms controlling mineral transport have been elucidated in rice and other species, little is understood in sorghum-an important C4 cereal crop. Here, we assessed the genetic factors that govern grain ionome profiles in sorghum using recombinant inbred lines (RILs) derived from a cross between BTx623 and NOG (Takakibi). Pairwise correlation and clustering analysis of 22 elements, measured in sorghum grains harvested under greenhouse conditions, indicated that the parental lines, as well as the RILs, show different ionomes. In particular, BTx623 accumulated significantly higher levels of cadmium (Cd) than NOG, because of differential root-to-shoot translocation factors between the two lines. Quantitative trait locus (QTL) analysis revealed a prominent QTL for grain Cd concentration on chromosome 2. Detailed analysis identified SbHMA3a, encoding a P1B-type ATPase heavy metal transporter, as responsible for low Cd accumulation in grains; the NOG allele encoded a functional HMA3 transporter (SbHMA3a-NOG) whose Cd-transporting activity was confirmed by heterologous expression in yeast. BTx623 possessed a truncated, loss-of-function SbHMA3a allele. The functionality of SbHMA3a in NOG was confirmed by Cd concentrations of F2 grains derived from the reciprocal cross, in which the NOG allele behaved in a dominant manner.
