The rice protein Ptr defends against blast disease by detecting the effector AVR-Pita in an allele-specific manner. The immune receptor Pi-ta proved to have no function in this process, contrary to what was previously reported.
The authors present the design principles of a synthetic earthmoss (Physcomitrium patens) genome. To aid future genome design projects, they also develop GenoDesigner, a software package that provides users with an intuitive graphical interface to efficiently manipulate genomic sequences.
In Marchantia polymorpha, sperm cells are released from the antheridium into the surroundings. The process is facilitated by MpMLO1, which initiates Ca2+-dependent programmed cell death of tip jacket cells of the mature antheridium, enabling water to enter and ultimately resulting in the bursting of the antheridium and the discharge of sperm.
The manual-labour-intensive hybrid seed production process is a limiting step for fully mechanized hybrid rice breeding. This work demonstrates that the use of ideal small-grain alleles of GSE3 enables fully mechanized hybrid rice breeding.
The endosperm is a seed tissue that supports the embryo. In most flowering plant species, the endosperm starts as a coenocyte that cellularizes after a defined number of mitotic divisions. We show that endosperm cellularization is under antagonistic parental control mediated by a family of maternally expressed auxin response factors.
This study reports the structure of a photosystem I assembly intermediate isolated from greening oat seedlings. It defines PsaF as a regulatory checkpoint promoting the association of LHCI that couples biogenesis to function.
Analyses of three newly sequenced modern cultivar cotton genomes revealed sequence and structural variation alongside traces of ancient and ongoing introgressions. Moreover, transcriptome analysis pointed at unique fibre quality traits of cultivars.
In most flowering plants, early divisions of endosperm nuclei are not succeeded by cellularization. This study uncovered a family of clustered auxin response factors as dosage-sensitive, maternally expressed regulators of endosperm cellularization.
Creation of a plastid genome without an inverted repeat in Nicotiana tabacum reveals a role for the inverted repeat in gene dosage and the regulation of replication by total DNA content rather than copy number.
Removing the large inverted repeat region from the chloroplast genome revealed a gene dosage benefit for the ribosomal RNA operon. The reduced genome size resulted in increased genome copy numbers and offers potential for synthetic biology.
The nuclear pore is known as a large protein complex for the transport of macromolecules between the nucleus and the cytoplasm. Comprehensive proteomic analyses revealed a novel role of the nuclear pore complex as a platform for the coordinated regulation of the flow from transcription to translation.
Tang et al. utilized proximity labelling to assemble the Arabidopsis nuclear pore-associated proteome and revealed the nuclear pore as an integrated platform coupling multiple steps in gene expression regulation, beyond its conventional transport role.
Quan et al. show that warming-induced changes in plant community height in a cold, high-elevation region enhance ecosystem carbon sequestration, emphasizing the importance of plant traits in shaping the carbon cycle under climate change.
