🌱 RESEARCH 🌱

Phloem cell proliferation in Plasmodiophora brassicae-induced clubroot galls doesn't directly depend on PEAR transcription factors, despite transcriptional up-regulation - Singh et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @sdeeksha1994.bsky.social @malinowskilab.bsky.social
Fig. 1 (shortened, full legend in paper): Simplified clubroot disease cycle in A. thaliana depicting characteristic cellular events during P. brassicae-induced gall formation. (A) P. brassicae resting spores under optimal conditions give rise to zoospores invading root hairs of a suitable Brassicaceae host plant, here Arabidopsis. Eventually the pathogen develops secondary zoospores that can be released into the soil and, after conjugation, form a uninucleate secondary plasmodium that re-infects the host (secondary/cortical infection). Secondary infection leads to development of a gall, that becomes conspicuous from as early as 10 DAI. Cellular events associated with gall formation during this stage include dynamic changes in cell cycle progression which result in hyperplasia. The stage between 10 and 19 DAI can be referred to as the proliferative phase of gall formation.

(C–L) Representative images of gametophytes at different days after inoculation onto growth medium: (C) 20, (D) 31, (E) 86, (F–J) 111, (K) 133, and (L) 129. Arrows in (G–K) indicate meristem notches. The dashed circle in (L) highlights a cluster of multiple meristems and prothalli derived from a single gametophyte body. Scale bars are 5 mm in (A, L) and 100 μm in (B–K). The gametophyte shown in (I) developed independent new meristems (arrows); the one on the left is also shown in Supplementary Fig. S2C. The images shown in (C–E) and in (F–K) are representative of at least 40 and 12 independent gametophytes observed during the developmental stages, respectively.

Resistance against bacterial wilt in tomato is linked to variety-specific proteomic changes; the CAPE1 peptide restricts Ralstonia solancearum growth in planta - Zhang et al. 🦠🍅

Fig. 3.PR1 protein features and alignment. (A) Representation of the tomato PR1 protein domains and conserved features. SP, signal peptide; CAP, cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1 protein domain, highlighting CAP3, CAP4, CAP1, CAP2, and CBM motifs; CAPE, CAP-derived peptide (Han et al., 2023). (B) Alignment of the representative PR1 proteins across different plant species. Amino acid alignment generated from ClustalO alignment of the representative PR1 proteins from tomato (Solanum lycopersicum), potato (Solanum tuberosum), pepper (Capsicum anuum), tobacco (Nicotiana tabacum), Arabidopsis (Arabidopsis thaliana), and wheat (Triticum aestivum). Red and blue highlighted regions show the last amino acid before the putative CAPE peptide cleavage. The conserved CAPE peptide sequence is shown in red.
