The intracellular ROS accumulation in elicitor‐induced immunity requires the multiple organelle‐targeted Arabidopsis NPK1‐related protein kinases

Lucia Marti, Daniel‐Valentin Savatin, Nora Gigli‐Bisceglia, Valeria Turris, more

Plant, Cell & Environment > 44 > 3 > 931 - 947

Recognition at the plasma membrane of danger signals (elicitors) belonging to the classes of the microbe/pathogen‐ and damage‐associated molecular patterns is a key event in pathogen sensing by plants and is associated with a rapid activation of immune responses. Different cellular compartments, including plasma membrane, chloroplasts, nuclei and mitochondria, are involved in the immune cellular program...

Cell wall modification by the xyloglucan endotransglucosylase/hydrolase XTH19 influences freezing tolerance after cold and sub‐zero acclimation

Daisuke Takahashi, Kim L. Johnson, Pengfei Hao, Tan Tuong, more

Plant, Cell & Environment > 44 > 3 > 915 - 930

Freezing triggers extracellular ice formation leading to cell dehydration and deformation during a freeze–thaw cycle. Many plant species increase their freezing tolerance during exposure to low, non‐freezing temperatures, a process termed cold acclimation. In addition, exposure to mild freezing temperatures after cold acclimation evokes a further increase in freezing tolerance (sub‐zero acclimation)...

Naturally occurring circadian rhythm variation associated with clock gene loci in Swedish Arabidopsis accessions

Hannah Rees, Ryan Joynson, James K. M. Brown, Anthony Hall

Plant, Cell & Environment > 44 > 3 > 807 - 820

Circadian clocks have evolved to resonate with external day and night cycles. However, these entrainment signals are not consistent everywhere and vary with latitude, climate and seasonality. This leads to divergent selection for clocks which are locally adapted. To investigate the genetic basis for this circadian variation, we used a delayed fluorescence imaging assay to screen 191 naturally occurring...

Comprehensive analysis of the isomiRome in the vegetative organs of the conifer Pinus pinaster under contrasting water availability

Pedro Perdiguero, Andreia Santos Rodrigues, Inês Chaves, Bruno Costa, more

Plant, Cell & Environment > 44 > 3 > 706 - 728

An increasing number of microRNAs (miRNAs) and miRNA‐related sequences produced during miRNA biogenesis, comprising the isomiRome, have been recently highlighted in different species as critical mediators of environmental stress responses. Conifers have some of the largest known genomes but an extensive characterization of the isomiRome from any conifer species has been lacking. We provide here a...

Leaf photosynthetic and anatomical insights into mechanisms of acclimation in rice in response to long‐term fluctuating light

Ze Wei, Fengying Duan, Xuezhen Sun, Xianliang Song, more

Plant, Cell & Environment > 44 > 3 > 747 - 761

Long‐term fluctuating light (FL) conditions are very common in natural environments. The physiological and biochemical mechanisms for acclimation to FL differ between species. However, most of the current conclusions regarding acclimation to FL were made based on studies in algae or Arabidopsis thaliana. It is still unclear how rice (Oryza sativa L.) integrate multiple physiological changes to acclimate...

Modelling the physiological relevance of sucrose export repression by an Flowering Time homolog in the long‐distance phloem of potato

Bas Herik, Sara Bergonzi, Christian W. B. Bachem, Kirsten ten Tusscher

Plant, Cell & Environment > 44 > 3 > 792 - 806

Yield of harvestable plant organs depends on photosynthetic assimilate production in source leaves, long‐distance sucrose transport and sink‐strength. While photosynthesis optimization has received considerable interest for optimizing plant yield, the potential for improving long‐distance sucrose transport has received far less attention. Interestingly, a recent potato study demonstrates that the...

The transcriptional repressor OsPRR73 links circadian clock and photoperiod pathway to control heading date in rice

Liwen Liang, Zhanyi Zhang, Niannian Cheng, Haiyang Liu, more

Plant, Cell & Environment > 44 > 3 > 842 - 855

The phase transition from vegetative to reproductive growth is triggered by internal and external signals that participate in circadian clock in plants. We identified a rice floral inhibitor OsPRR73 encoding a CONSTANS protein. Overexpression of OsPRR73 resulted in late heading under both long‐day (LD) and short‐day (SD) conditions. Knockout mutants led to early heading under LD conditions but no...

Overexpression of the homoterpene synthase gene, OsCYP92C21, increases emissions of volatiles mediating tritrophic interactions in rice

Wei Li, Lingnan Wang, Fei Zhou, Changyan Li, more

Plant, Cell & Environment > 44 > 3 > 948 - 963

Plant defence homoterpenes can be used to attract pest natural enemies. However, the biosynthetic pathway of homoterpenes is still unknown in rice, and the practical application of such indirect defence systems suffers from inherent limitations due to their low emissions from plants. Here, we demonstrated that the protein OsCYP92C21 is responsible for homoterpene biosynthesis in rice. We also revealed...

Ethylene is a local modulator of jasmonate‐dependent phenolamide accumulation during Manduca sexta herbivory in Nicotiana attenuata

Florent Figon, Ian T. Baldwin, Emmanuel Gaquerel

Plant, Cell & Environment > 44 > 3 > 964 - 981

Rapid reconfigurations of interconnected phytohormone signalling networks allow plants to tune their physiology to constantly varying ecological conditions. During insect herbivory, most of the induced changes in defence‐related leaf metabolites are controlled by jasmonate (JA) signalling, which, in the wild tobacco Nicotiana attenuata, recruits MYB8, a transcription factor controlling the accumulation...

Diurnal dynamics of the Arabidopsis rosette proteome and phosphoproteome

R. Glen Uhrig, Sira Echevarría‐Zomeño, Pascal Schlapfer, Jonas Grossmann, more

Plant, Cell & Environment > 44 > 3 > 821 - 841

Plant growth depends on the diurnal regulation of cellular processes, but it is not well understood if and how transcriptional regulation controls diurnal fluctuations at the protein level. Here, we report a high‐resolution Arabidopsis thaliana (Arabidopsis) leaf rosette proteome acquired over a 12 hr light:12 hr dark diurnal cycle and the phosphoproteome immediately before and after the light‐to‐dark...

NtMYB12a acts downstream of sucrose to inhibit fatty acid accumulation by targeting lipoxygenase and SFAR genes in tobacco

Zhong Wang, Ze Feng Li, Shan Shan Wang, Yan Song Xiao, more

Plant, Cell & Environment > 44 > 3 > 775 - 791

MYB12 promotes flavonol biosynthesis in plants by targeting several early biosynthesis genes (EBGs) of this pathway. The transcriptions of these EBGs are also induced by sucrose signal. However, whether MYB12 is activated by sucrose signal and what the other roles MYB12 has in regulating plant metabolism are poorly understood. In this study, two NtMYB12 genes were cloned from Nicotiana tabacum. Both...

Differential localization of flavonoid glucosides in an aquatic plant implicates different functions under abiotic stress

Laura Böttner, Veit Grabe, Saskia Gablenz, Niklas Böhme, more

Plant, Cell & Environment > 44 > 3 > 900 - 914

Flavonoids may mediate UV protection in plants either by screening of harmful radiation or by minimizing the resulting oxidative stress. To help distinguish between these alternatives, more precise knowledge of flavonoid distribution is needed. We used confocal laser scanning microscopy (cLSM) with the “emission fingerprinting” feature to study the cellular and subcellular distribution of flavonoid...

Bioenergy sorghum maintains photosynthetic capacity in elevated ozone concentrations

Shuai Li, Christopher A. Moller, Noah G. Mitchell, DoKyoung Lee, more

Plant, Cell & Environment > 44 > 3 > 729 - 746

Elevated tropospheric ozone concentration (O₃) significantly reduces photosynthesis and productivity in several C₄ crops including maize, switchgrass and sugarcane. However, it is unknown how O₃ affects plant growth, development and productivity in sorghum (Sorghum bicolor L.), an emerging C₄ bioenergy crop. Here, we investigated the effects of elevated O₃ on photosynthesis, biomass and nutrient composition...

Soybean CHX‐type ion transport protein GmSALT3 confers leaf Na⁺ exclusion via a root derived mechanism, and Cl⁻ exclusion via a shoot derived process

Yue Qu, Rongxia Guan, Jayakumar Bose, Sam W. Henderson, more

Plant, Cell & Environment > 44 > 3 > 856 - 869

Soybean (Glycine max) yields are threatened by multiple stresses including soil salinity. GmSALT3 (a cation‐proton exchanger protein) confers net shoot exclusion for both Na⁺ and Cl⁻ and improves salt tolerance of soybean; however, how the ER‐localized GmSALT3 achieves this is unknown. Here, GmSALT3's function was investigated in heterologous systems and near isogenic lines that contained the full‐length...

Dynamic thermal imaging confirms local but not fast systemic ABA responses

Hanna Hõrak, Luke Fountain, Jessica A. Dunn, Joanna Landymore, more

Plant, Cell & Environment > 44 > 3 > 885 - 899

Abscisic acid (ABA) signals regulating stomatal aperture and water loss are usually studied in detached leaves or isolated epidermal peels and at infrequent timepoints. Measuring stomatal ABA responses in attached leaves across a time course enables the study of stomatal behaviour in the physiological context of the plant. Infrared thermal imaging is often used to characterize steady‐state stomatal...

Acclimatisation of guard cell metabolism to long‐term salinity

Bastian Leander Franzisky, Christoph‐Martin Geilfus, Maria Luisa Romo‐Pérez, Ines Fehrle, more

Plant, Cell & Environment > 44 > 3 > 870 - 884

Stomatal movements are enabled by changes in guard cell turgor facilitated via transient accumulation of inorganic and organic ions imported from the apoplast or biosynthesized within guard cells. Under salinity, excess salt ions accumulate within plant tissues resulting in osmotic and ionic stress. To elucidate whether (a) Na⁺ and Cl⁻ concentrations increase in guard cells in response to long‐term...
