RNA‐Guided Engineering of the Chloroplast Genome Enabled by Plastid‐Expressed Guide RNAs

Plant Biotechnology Journal, Volume 24, Issue 10, Page 5498-5509, October 2026.
ABSTRACT Our goal is to develop RNA‐guided engineering of the chloroplast genome using the CRISPR/Cas9 system. We designed chloroplast minigenes to obtain properly sized single guide RNAs (sgRNAs) in tobacco chloroplasts. The sgRNA 5′ end is defined by transcription from an rRNA operon promoter, and its 3′ end by processing a downstream tRNA (trnG) or ...

Evaluation of HSYA and Carthamin Accumulation in Safflower (Carthamus tinctorius L.) Induced by Chemical Mutagens (EMS and SA) in M1 and M2 Generations

Plant Breeding, Volume 145, Issue 5, Page 868-880, October 2026.
ABSTRACT Historically cultivated for medicinal and dyeing purposes, safflower (Carthamus tinctorius L.) saw a shift towards widespread oilseed production after the 1920s due to the growing importance of oils. However, there is a renewed interest in its medicinal and dyeing properties today.

Underground allies: Mycorrhizal flexibility facilitates orchid occurrence in post‐mining landscapes

Plant Biology, Volume 28, Issue 6, Page 1899-1911, October 2026.
Epipactis helleborine associates with largely habitat‐specific fungal communities, with limited overlap between mining and woodland sites, yet maintains comparable genetic diversity across habitats. These results highlight the role of mycorrhizal flexibility in enabling habitat shifts and expanding ecological niches in human‐altered landscapes ...

Root‐sourced 1‐aminocyclopropane‐1‐carboxylic acid modulates development and adaptive responses to salinity in tomato

The Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY To investigate whether root‐sourced ethylene‐precursor 1‐aminocyclopropane‐1‐carboxylic acid (ACC) modulates long‐term salinity responses in tomato, a commercial variety (Solanum lycopersicum L. Mill) was grafted onto three rootstocks differing in ACC/ethylene production: an ethylene‐overproducing mutant (epinastic, epi), a root‐specific ACC ...

A wheat‐specific proline‐rich protein regulates grain weight through a ubiquitin‐mediated delay of endosperm cellularization

The Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY Grain weight is a key determinant of wheat yield, yet the developmental mechanisms that define this trait remain poorly understood. Here, we identify TaPGW1‐A1, a wheat‐specific proline‐rich gene that regulates grain weight. TaPGW1‐A1 is a recently evolved gene found only in wheat.

Cytochrome P450 enzymes in the phenylpropanoid pathway: CYP73 and CYP98 candidate genes in Chara braunii, Anthoceros agrestis, Marchantia polymorpha and Physcomitrium patens

The Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY CYP73 and CYP98 are two cytochrome P450 monooxygenase families present in bryophytes and tracheophytes, and they play key roles in the formation of phenolic compounds containing a caffeic acid moiety and more complex phenolic compounds. CYP73 encodes the second enzyme in the core phenylpropanoid pathway and is the first enzyme family in this ...

ZmDLR9 is required for lateral root development via pre‐rRNA processing in maize

The Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY Pumilio (PUM) proteins comprise an evolutionarily conserved family of sequence‐specific RNA‐binding proteins that act as key post‐transcriptional regulators in eukaryotes. In this study, we identified a maize PUM protein, named ZmDLR9 (Defective in Lateral Root 9), as a positive factor involved in lateral root development.

Temporal phenotypic responses of early vegetative maize to heat, drought, and combined stresses

The Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY Understanding how maize responds to heat, drought, and the combination of stresses is essential for developing resilient cultivars for future climates. We characterized temporal phenotypic responses of 47 genetically diverse Zea mays inbred lines grown under control, drought, heat, and combined drought‐heat stresses for 13 days in a high ...
