🟠🍅 SPECIAL ISSUE EXPERT VIEW 🍅🟠

Tomato carotenoids contribute to photosynthesis, color ripe fruit and produce bioactive signals.
Rodriguez-Concepcion et al. provide an update on how paralogs of key biosynthetic enzymes control carotenoid production.

🔗 doi.org/10.1093/jxb/...
#PlantScience 🧪
Box 1. Key developments in understanding the role of enzyme paralogs feeding the carotenoid pathway in tomato The steps catalyzed by DXS, GGPPS, and PSY are shown in a schematic pathway. The relative contribution of individual paralogs to carotenoid biosynthesis in different tomato organs is represented in the lower panel (the paler the color, the weaker the contribution of the corresponding isoform; no color means no contribution). The main findings of the indicated papers are also indicated in the figure.

CRISPR/Cas technology is an emerging tool for identifying nucleic acid sequences.

Hak et al. present a user-friendly, extraction-free, rapid protocol for specific on-site detection of plant viruses using CRISPR/Cas13a.

Viral RNA can be detected in a 1:5 dilution using this method. (B) Equipment required for on-site diagnostics includes dry bath, vortex, portable fluorescence viewer, a pipette, and test tubes. (C) Schematic illustration of virus detection using a portable fluorescence viewer and a cellular phone camera. (D) Mobile phone camera image of serial dilutions of crude RNA from ToBRFV-infected plants. (E) Samples are converted to grayscale. (F) Fluorescence intensity is quantified using ImageJ.

The endosomal sorting complex protein FYVE4, vital for biogenesis of multivesicular endosomes & vacuolar degradation of membrane proteins, interacts with PYL receptors to destabilize PYL4 & suppress abscisic acid signaling - Chen et al.

#PlantScience 🧪
Fig. 5 2 (shortened, full legend in paper): ABA positively regulates FYVE4 expression and enhances FYVE4–PYL4 interaction. (A) RT-qPCR assay to determine the transcriptional level of FYVE4 in response to ABA. Five-day-old seedlings were transferred to a liquid medium in the presence or absence of 50 μM ABA for the indicated times, then were collected for RNA extraction and RT-qPCR assay. ACTIN2 was used as the reference gene for statistical analysis. Three replicates were conducted, with values representing the mean ±SE. (B) FYVE4 protein showed an increasing and then decreasing trend in response to ABA treatment. Seedlings of the WT grown on solid 1/2 MS medium for 5 d were transferred to liquid medium containing 50 μM ABA for the indicated times. Samples were collected and subjected to immunoblot assays with FYVE4 and Actin antibodies.

Trehalose 6-phosphate, a sugar signalling metabolite, is mainly present in the bundle sheath cells of Setaria viridis leaves - Tonetti et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Fig. 1.Phylogenetic relationships of Setaria viridis TPS proteins. TPS protein sequences were collated from Setaria viridis (Sv) and other selected species: Ac, Ananas comosus; At, Arabidopsis thaliana; Bd, Brachypodium distachyon; Mc, Musa acuminata; Os, Oryza sativa; Pt, Populus trichocarpa; Pv, Phaseolus vulgaris; Ta, Triticum aestivum; Zm, Zea mays (see Supplementary Table S1 for gene/protein identifiers). A distance-based tree was reconstructed using the BioNJ algorithm. Numbers in nodes represent the bootstrap obtained for 1000 replicates. The tree is rooted on the E. coli TPS (otsA). Subclades in the tree are coloured according to the position of A. thaliana TPS sequences, with the exception of the monocot-specific subclade. S. viridis sequences are highlighted.

🛡️ INSIGHT 🛡️

"Barley powdery mildew effector CSEP0162 interacts with the endosome membrane-binding domain of barley MON1" - Deb et al. share an update relevant to their earlier work, Liao et al. (2022) 🌾

#PlantScience 🧪
Fig. 1 (shortened, full legend in paper): CSEP0162 interacts with the C-terminus, but not ‘full-length’ HvMON1 in Y2H. The yeast strain Y8930 was transformed with constructs fusing either CSEP0162, CSEP0105, or HvCCZ1 with the GAL4 DNA-binding-domain (BD) (pDEST-AS2-1 vector, cloned from respective pENTR clones using Gateway LR cloning). The yeast strain Y8800 was transformed with either empty vector pDEST-ACT2, or constructs fusing either amino acids 22–598 of HvMON1 or the C-terminus (amino acids 539–598) of HvMON1 with the activation domain (AD) (pDEST-ACT2 vector, cloned from the respective pENTR clones using Gateway LR cloning). Transformed strains were mated in the listed combinations and plated on dropout (DO) medium lacking leucine (L) and tryptophan (W). Drop test was performed by adjusting cultures to OD600 = 1.0 (100), and with further serial dilutions (10–1 and 10–2). Growth on these plates indicates the presence of both constructs.

💨🌿 REVIEW 💨🌿

Environmental factors such as wind and plant-specific traits including leaf size can be manipulated to alleviate limitations imposed on photosynthesis by low leaf boundary layer conductance - Dupont et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @silverevialet.bsky.social
Fig. 3 (shortened, full legend in paper): Schematic representation of CO2 diffusion through the leaf boundary layer and into the chloroplast under different wind speeds. The cross-sections represent a leaf with a uniform boundary layer and show the diffusional path of CO2 from the ambient air to the stomatal aperture and then to the chloroplast, under two different wind conditions. The corresponding distribution of [CO2] is shown, as indicated in the key. (A) A low wind speed results in a relatively thick boundary layer where [CO2] decreases from 420 µmol mol−1 in the ambient air (⁠ ⁠), to 350 µmol mol−1 in the air at the stomatal aperture (⁠ ⁠), to 270 µmol mol−1 in the intercellular airspace (⁠ ⁠).

#JXBspecialissues #PlantScience 🧪 @sebiology.bsky.social
Vol 76 | Issue 19 | 2025 Journal of Experimental Botany Peptides: A Treasure Chest of Structures and Functions Cover illustration: Plant peptides play critical roles in a plethora of developmental processes and stress responses. These biomolecules, derived from either the translation of short open reading frames or the proteolytic cleavage of protein precursors, can act as key signaling molecules, metabolic regulators, and structural components of larger complexes. With potential applications in agriculture, medicine, and beyond, the power of peptides and the importance of their study cannot be understated. (Image courtesy of Alyssa Kearly.)

Iron retention, coupled with symbiotic associations driven by the enrichment of Variovorax and Paecilomyces in the roots, confers tolerance to combined iron deficiency and drought in soybean - Hasan et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Fig. 10 (shortened, full legend in paper): A model of stress resilience in Clark exposed to Fe deficiency and drought. The model illustrates the mechanisms underlying stress resilience, including enhanced Fe and N retention mediated by root-localized symbiotic interactions with Bradyrhizobium, Paecilomyces, and Variovorax. Key transporters such as Ammonium transporter 1;2, EamA-like transporter, Sugar transporter 1, and SWEET10 facilitate nutrient exchange and carbon flow. Fe homeostasis is maintained through the activity of ferric chelate reductase (FCR), Fe-regulated protein 3, and siderophore-mediated Fe acquisition. Reactive oxygen species (ROS) are scavenged by Peroxidase 19, Glutaredoxin 4, and Glutathione peroxidase 6, while ferritin provides additional protection by inhibiting Fenton reactions.

Endoplasmic reticulum stress induced by necrotrophic fungal pathogens activates the unfolded protein response pathway in Arabidopsis via the IRE1-bZIP60 arm, and this is required for immunity to these pathogens- Blanchard et al. 🍄

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Fig. 10 (shortened, full legend in paper): Schematic representation of the role of the unfolded protein response (UPR), endoplasmic reticulum (ER) quality control (ER-QC), and ER-associated degradation (ERAD) during Botrytis cinerea infection of Arabidopsis thaliana plants. Infection with B. cinerea induces ER stress, which activates the canonical IRE1-bZIP60 branch of the UPR and the expression of the genes encoding the ER-QC machinery (BiP, ERDJ3, SDF2). We hypothesized that the activation of these signalling pathways might control the secretion of defence proteins that are necessary to establish defence against B. cinerea. Our data also indicate that active bZIP60 suppresses the expression of NAC053, a negative regulator of defence against B. cinerea. However, NAC053 expression depends on IRE1.
