🌽 Maize vs. Fusarium 🌽

Overexpressing a maize lipoxygenase (ZmLOX4) boosts resistance to Fusarium infection.

Glad that our maize Gene editing & transformation platform, at @rdplab.bsky.social, contributed to this research, led by the Lanubile's Lab.

Box 1. Key developments in understanding FtsH functions for organelle protein homeostasis in Arabidopsis The schematic illustration shows the primary and 3D structure of FtsH (A–C) and highlights recent advances in understanding the roles of plant FtsHs localized in chloroplasts (D, E, and H) and mitochondria (F and G).

💡 SPECIAL ISSUE VIEWPOINT 💡

Immune proteases are promising targets for protein engineering 🛠️ to boost disease resistance in plants 🌾 - Schuster et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @marischuster.bsky.social @aciattoni.bsky.social
Fig. 1.Four classes of roles of immune proteases illustrated via examples. (i) Pathogen perception: Required for Cladosporium Resistance-3 (Rcr3) protease is inhibited by the fungal avirulence effector Avr2. The Rcr3-Avr2 complex is recognized by the immune receptor Cf-2, triggering a defence response (Kruger et al, 2002). (ii) Regulation of the immune response: METACASPASE 4 (MC4) is activated by calcium upon wounding or pathogen attack. MC4 cleaves tonoplast-located ProPEP1 releasing PEP1 to the apoplast where it is perceived by PEP RECEPTORS (PEPRs) thereby initiating defence responses (Hander et al, 2019). (iii) Counteracting pathogen effectors: soybean aspartic protease GmAP5, degrades the Phytophthora sojae virulence factor glycoside hydrolase family 12 (GH12) protein, XEG1 (Xia et al., 2020). (iv) Direct pathogen attack: secreted aspartic proteases (SAPs) cleave Pseudomonas syringae MucD protein thereby suppressing bacterial growth (Wang et al., 2019).

🌳🌴 RESEARCH 🌳🌴

Along a climate warming gradient, Australian tropical rainforest tree species showed reduced growth with more allocation to roots whereas temperate rainforest tree species allocated more biomass to leaves – Choury et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Fig. 1.The stem volume (cm3) growth of seedlings of rainforest tree species during the experiment under different growth temperatures. Species were of temperate (A–D), subtropical (E–H), and tropical (I–L) origin along the eastern coast of Australia. Points reflect the mean and 1 standard error from 10 replicate plants. Growth temperatures are indicated in different colours with cyan (24 °C) and red (27.5 °C) colours being common across all species. Results reflect surviving species only, with fewer replicates in the 34.5 °C group: two replicates of Syzygium wilsonii, four replicates of Dysoxylum fraserianum, and five replicates of Cryptocarya mackinnoniana and Syzygium luehmannii. Tasmannia lanceolata experienced total mortality at 27.5 °C after 2 months.

With GWAS, Ali et al. identified high confidence signals associated with chlorophyll, ΦPSII, ΦNPQ, & qL variation. Arabidopsis ortholog insertion alleles of maize candidates had photosynthesis-related phenotypes in line with the GWAS.

(A) Estimated genotype-level heritability across two replicated plots in the same field for plot-level averages (n = 2), uncorrected for environmental or spatial confounders, of 14 traits scored in the field using MultiSpeQs. (B) Estimated proportion of variance in individual measurements (n = 6) of the same 14 traits attributable to genotype, light intensity recorded at the time of collection, day on which the measurement was taken, and row and column position within the field. (C) Estimated genotype-level heritability across two replicated plots (n = 2) in the same field for plot-level trait estimates generated after correcting for the effects of light intensity and day as well as 2D spatial variation throughout the field using SpATS.
