🌱🦠 RESEARCH 🦠🌱

This investigation reveals that plant viral proteins (e.g. the PMMoV 126 kDa protein) hijack amino acid metabolism mediated by L-asparaginase, thereby reversing plant immunity toward favoring viral infection - He et al.

Fig. 2 (shortened, full legend in paper): LA negatively regulates host antiviral defense. (A) Phenotypes of PMMoV-infected N. benthamiana plants silenced for NbLA-1/2 (TRV–NbLA-1/2; a 600 bp fragment generated by fusing 300 bp segments from NbLA-1 and NbLA-2). Symptoms were recorded 3 days post-inoculation (dpi). (B) Immunoblot analysis of PMMoV CP protein levels from (A); Ponceau S staining served as the loading control. Quantification was normalized relative to the TRV–GUS control, with its average value set to 1. (C) Phenotypes of PMMoV-infected Capsicum annuum plants silenced for CaLA-1/2 (TRV–CaLA-1/2). Symptoms were observed 5 dpi. (D) Immunoblot analysis of PMMoV CP protein levels from (C) with Ponceau S loading control. (E) Phenotypes of PMMoV-infected WT, OE–NbLA-1, and OE–NbLA-2 N. benthamiana plants at 3 dpi. (F, G) Immunoblot analysis of PMMoV CP levels in plants from (E). Ponceau S staining was used as a loading control; the average value for the WT was set to 1.

Floral Friday...🪷

Mao et al show that orchid #MYB factor (PaMYB55) positively regulates cell expansion & wall integrity by promoting lignin & cellulose biosynthesis, contributing to both floral morphology & defense against pathogen spread

doi.org/10.1093/pcp/...

#PlantScience

Images showing the effects of VIGs silencing of PaMYB55 leading to a decrease in cellulose and lignin content in the peduncle. (a, b) panels show inflorescence with flowers from mock (a) and PaMYB55-VIGS (b) plants. Panels c,d, show close-ups of the peduncles shown in (a) and (b). Panels e,f, show distribution of cellulose and lignin examined by CLSM. panels g-l show close-up images of cellulose (g), lignin (h), and merged (i) signals from the boxed region in (e) of the mock peduncle. Image taken from figure 6 of Wan-Ting Mao, Wei-Han Hsu, Pei-Tzu Lin, Chang-Hsien Yang, PaMYB55 regulates cellulose and lignin deposition to control floral organ development, cell wall integrity, and pathogen resistance in Phalaenopsis orchids, Plant and Cell Physiology, Volume 67, Issue 8, August 2026, Pages 1414–1429, https://doi.org/10.1093/pcp/pcag062

TaR3H interacts with Pm21CC, and the interaction is enhanced upon pathogen infection, positively regulating disease resistance through hormone signaling pathways - Si et al.

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪

Fig. 1.Physical interactions between TaR3H and Pm21 by yeast two-hybrid assay. (A) The interaction assays between TaR3H and Pm21FL or five truncated Pm21 fragments (CC, NBS, LRR, CC-NBS, and NBS-LRR). (B) The interaction assays between Pm21CC and TaR3H or five truncated TaR3H fragments (P1, R3H associated, P3, R3H domain, and P5). The original plasmids are the Gal4 DNA-binding domain vector (pGBKT7) and the Gal4 activation domain vector (pGADT7). All constructs were subsequently pairwise co-transformed into the yeast strain AH109 for protein interaction studies. Positive control: pGADT7-largeT+pGBKT7-53; negative control: pGADT7-largeT+pGBKT7-Lam. Yeast transformants were grown on selective media: SD/-TL (lacking tryptophan and leucine), SD/-TLH (lacking tryptophan, leucine, and histidine), and SD/-TLHA (lacking tryptophan, leucine, histidine, and adenine, with or without X-α-gal).

We like to think that new crop varieties are developed without modern techniques. But the honest story is that most are, even if they are not gene edited or genetically modified. So how do plant breeders now-a-days develop new crop varieties?
