This approach revealed two separable ABA-responsive modules that contribute to yield formation: one enhancing drought resilience through improved stomatal regulation, and another restoring reproductive success by promoting pollen viability and anther development. These physiological responses, governed by spatially distinct sites of ABA action, partially mitigated the yield penalties associated with ABA deficiency, although neither alone was sufficient to fully restore productivity.

In plants, the plastid genes are transcribed by two RNA polymerases: the plastid-encoded multisubunit plastid RNA polymerase (PEP) and the phage-type, nuclear-encoded single subunit RNA polymerase (NEP). NEP does not recognize the T7 RNAP gene 10 promoter (PT7) and leader containing a ribosome binding site in vivo (McBride et al. &lt;span&gt;1994&lt;/span&gt;) or in chloroplast extracts (Liere and Maliga &lt;span&gt;1999&lt;/span&gt;), and T7 RNAP does not recognize plastid NEP promoters (Liere and Maliga &lt;span&gt;1999&lt;/span&gt;), making the T7 RNAP suitable for application as an orthogonal transcription system in plastids. Here, we employ the T7 RNAP and the cognate PT7 promoters for seed-specific expression of plastid transgenes activated by a seed-specific promoter.&lt;/p&gt;&lt;p&gt;Expression of recombinant proteins in plastids has the advantages of high-level protein accumulation, expression of multiple genes in operons, and maternal inheritance for biocontainment (Maliga &lt;span&gt;2021&lt;/span&gt;). However, plastid transgenes are usually expressed in leaf chloroplasts, which are perishable and require lyophilization of leaf or purification of recombinant proteins (Twyman et al. &lt;span&gt;2003&lt;/span&gt;). In contrast, seeds are natural storage organs that accumulate and protect the proteins during extended storage. Recently, we showed that seed plastids can serve as a platform for recombinant protein expression using a post-transcriptional activation system based on seed-specific expression of a plastid-targeted PPR10 RNA-binding protein, PPR10&lt;sup&gt;GG&lt;/sup&gt;, which binds its cognate site, BS&lt;sup&gt;GG&lt;/sup&gt;, located upstream of plastid transgenes (Mirzaee et al. &lt;span&gt;2024&lt;/span&gt;). Because this system is regulated post-transcriptionally, the mRNA is present even in the absence of PPR10&lt;sup&gt;GG&lt;/sup&gt;, for example, in leaves, resulting in recombinant protein accumulation in non-target tissues. Background levels of recombinant proteins in a posttranscriptionally regulated system are high, ~2% of total soluble cellular protein (TSP) in leaves. Transcriptional control restricts plastid mRNA production to the target tissue, avoiding unintended recombinant protein accumulation in non-target tissues. T7 RNAP has previously been used to selectively transcribe plastid transgenes driven by the cognate PT7 promoter, by expressing it from the nucleus and importing it into leaf chloroplasts (McBride et al. &lt;span&gt;1994&lt;/span&gt;; Lossl et al. &lt;span&gt;2005&lt;/span&gt;; Latif et al. &lt;span&gt;2022&lt;/span&gt;). Here, we extend the utilization of the orthogonal T7 RNAP/PT7 regulatory system for seed-specific expression of plastid transgenes.&lt;/p&gt;&lt;p&gt;For seed-specific expression of transgenes in plastids, we designed a two-component system.

{"title":"Correction to “Reduced Susceptibility to Phytophthora in Non-Transgenic Cacao Progeny Through CRISPR–Cas9 Mediated TcNPR3 Mutagenesis”","authors":"","doi":"10.1111/pbi.70722","DOIUrl":"10.1111/pbi.70722","url":null,"abstract":"<p>Guiltinan, M.J., Landherr, L., Maximova, S.N., DelVecchio, D., Sebastian, A. and Albert, I. (2026) Reduced Susceptibility to Phytophthora in Non-Transgenic Cacao Progeny Through CRISPR–Cas9 Mediated TcNPR3 Mutagenesis. Plant Biotechnology Journal 24: 442–454. https://doi.org/10.1111/pbi.70365</p><p>In the originally published article, the line designated GM-249 was identified as the cacao genotype Scavina-6 (Sca-6) and was used as a non-edited reference in the transcriptome analysis and as the pollen parent in one of the reported crosses. Whole-genome sequencing of the experimental genotypes has since established that GM-249 is the cacao clone ICS-1, not Scavina-6. The misidentification originated as a labeling error on the source plant and was detected only once genome-scale data became available; the corrected identity has been confirmed by whole-genome sequence comparison.</p><p>The correction changes the genotype label of GM-249 from “Scavina-6 (Sca-6)” to “ICS-1” in Table 1, the relevant figures and the supplementary materials, and in the description of the cross in which GM-249 (ICS-1) served as the pollen parent. A corrected Table 1 accompanies this correction.</p><p>This reassignment does not alter the study's principal conclusions. The most strongly supported and reproducible differential-expression signal derives from comparisons among lines in the PSU-Scavina-6 background, which do not involve GM-249 and are therefore unaffected. The corrected identity indicates that comparisons involving GM-249 span a more genetically divergent background than originally stated, which is consistent with, and reinforces, the paper's caution that genetic-background heterogeneity contributes substantially to the observed transcriptional variation. No quantitative result, figure, or conclusion other than the GM-249 genotype label requires revision.</p><p>We apologize for this error.</p>","PeriodicalId":221,"journal":{"name":"Plant Biotechnology Journal","volume":"24 9","pages":"5236-5238"},"PeriodicalIF":12.8,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/pbi.70722","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148428813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
