The study compared aphid resistance and Barley Yellow Dwarf Virus (BYDV) transmission among three wheat varieties (G1, RGT Wolverine, RGT Illustrious). G1 emits the repellent 2‑tridecanone, restricts aphid phloem access, and shows reduced BYDV transmission, whereas RGT Wolverine limits systemic viral infection despite high transmission efficiency. The authors suggest breeding the two resistance mechanisms together for improved protection.

The study investigated whether wheat homoeologous genes actively compensate for each other when one copy acquires a premature termination codon (PTC) mutation. By analyzing mutagenised wheat lines, the authors found that only about 3% of cases exhibited upregulation of the unaffected homoeolog, indicating that widespread active transcriptional compensation is absent in wheat.

Overexpression of the wheat bHLH transcription factor TaPGS1 leads to increased flavonol accumulation in the seed coat, which disrupts polar auxin transport and causes localized auxin accumulation, delaying endosperm cellularization and increasing cell number, thereby enlarging grain size. Integrated metabolomic and transcriptomic analyses identified upregulated flavonol biosynthetic genes, revealing a regulatory module that links flavonol-mediated auxin distribution to seed development in wheat.

The study evaluated how alginate oligosaccharide (AOS) chain length influences the levels of seven key phytohormones in wheat seedlings challenged with Botrytis cinerea. Hormone profiling revealed that mid‑range oligomers (DP 4‑6) most strongly up‑regulate defense‑related hormones (JA, SA, ABA, CTK), whereas longer oligomers (DP 7) most effectively suppress ethylene. These findings suggest that tailoring AOS polymerization can optimize disease resistance and growth in cereal crops.

The study investigates the function of two GT47B arabinan arabinosyltransferases in the liverwort Marchantia polymorpha, generating loss‑of‑function and overexpression lines to assess cell wall composition. Using CoMPP, glycosyl linkage analysis, and LM6 immunolabelling, the authors found that MpARADL2 mutants have reduced 1,5‑L‑arabinan epitopes in elaters despite unchanged overall 5‑linked Araf levels, suggesting additional enzymes compensate in thallus tissue. Attempts to express and purify the enzymes in HEK293 cells failed, implying a clade‑specific solubility requirement and highlighting the need to identify interacting partners.

The study characterizes the composition and structure of cell wall glycans in eight tissue types of the liverwort Marchantia polymorpha, revealing both typical land‑plant features and unique traits such as abundant (1,5)-arabinan in sporophytes and low overall pectin levels. Comparative genomic analysis shows a diversified glycosyltransferase repertoire relative to Arabidopsis, and the authors created a Gateway‑compatible library of 93 M. polymorpha GTs to facilitate future functional studies.

The authors identified MpCAFA, a protein combining CAPS-like and FAP115-like domains, as a key factor for rapid ciliary swimming in the liverwort Marchantia polymorpha spermatozoids. Loss-of-function mutants displayed markedly reduced swimming speed despite normal axoneme structure, chemotaxis, and fertility, and these defects were rescued by a MpCAFA‑mCitrine fusion that localized along the entire cilium. Both the CAPS-like and FAP115-like regions are required for MpCAFA’s function and ciliary targeting, establishing it as a major ciliary protein and a marker for visualizing spermatozoid motility.

The study investigated meristem activation in the liverwort Marchantia polymorpha, revealing that simulated shade causes alternating inactivity of meristems. Transcriptomic comparison of active versus inactive meristems identified the cytochrome P450 monooxygenase MpCYP78E1 as an inhibitor of meristem activity and initiation, with loss- and gain-of-function mutants confirming its regulatory role in shoot branching architecture.

The study examines how the SnRK1 catalytic subunit KIN10 integrates carbon availability with root growth regulation in Arabidopsis thaliana. Loss of KIN10 reduces glucose‑induced inhibition of root elongation and triggers widespread transcriptional reprogramming of metabolic and hormonal pathways, notably affecting auxin and jasmonate signaling under sucrose supplementation. These findings highlight KIN10 as a central hub linking energy status to developmental and environmental cues in roots.

The study demonstrates that MYB‑bHLH‑WDR transcriptional complexes (MBW) are present in the liverwort Marchantia polymorpha, indicating that such complexes originated before the diversification of land plants. Functional analyses reveal that two MYB paralogs, MpMYB14 and MpMYB02, rely on a single bHLH partner (MpbHLH12) to regulate flavonoid biosynthesis and liverwort‑specific oil body maturation, suggesting an ancestral role in pigment production and a derived role in organelle development.
