Genome sequencing and analyses of common buckwheat, Fagopyrum esculentum, reveal the genetic architecture of heterostyly, show that southeast Tibet played a key role in the domestication and provide new genetic materials for buckwheat breeding.
Flower formation across thermal environments is critical for efficient reproduction. This study reveals that temperature and the CLAVATA peptide signalling pathway intersect to confer robustness in hormone-dependent reproductive shoot development.
The study presents the structure of photosystem II supercomplex from Picea abies solved by cryo-electron microscopy and describes its unique features—the presence of light-harvesting protein Lhcb8 and an α-tocopherol molecule with potential physiological function.
Using 1,578 resequenced genomes representing the diversity of cultivated and wild rice, this study reveals that the domestication alleles of the 993 selected genes stemmed from both O. rufipogon and O. nivara, demonstrating multiple domestications of rice.
How plants coordinate growth and nutrient supply is a long-standing question in plant biology. This work discovers that transcription factors SOD7 and DPA4 interact with the transcriptional coactivator GIF1 to coordinate organ growth and iron uptake.
Genetic and ChIP–seq analyses of missense DELLA mutants reveal a role of the DELLA PFYRE subdomain in H2A binding, which stabilizes the transcription factor–DELLA–H2A complexes at the target chromatin for global transcription reprogramming.
The perennial weed, Johnsongrass, is a threat to global food security. Its two reproduction modes drive acquisition of herbicide resistance, but a well-strategized blend of tillage and diverse herbicides offers effective countermeasures.
This study reports haplotype-resolved genomes for Fragaria chiloensis and Fragaria virginiana, the progenitor species of cultivated strawberries. These high-quality genomes reveal the origin and genomic diversifications of octoploid strawberries.
Arabidopsis blue-light photoreceptor cryptochromes interact with ADA2b and SMC5 in a blue-light-dependent manner, which enhances ADA2b–SMC5 interaction and promotes ADA2b-mediated recruitment of SMC5 to DNA double-strand breaks, leading to break repair.
Ocean currents play a crucial role in the distribution of marine coastal species. Here the nuclear and chloroplast genomes of this eelgrass (Zostera marina L.) is used to trace its colonization history from its origin in the Northwest Pacific.
The high-resolution structure of an Lhcb9-dependent PSI complex from Physcomitrium patens reveals the assembly details of this complex and the underlying mechanism by which P. patens switches between different types of PSI complex.
The nuclear lamina in Arabidopsis, a protein meshwork beneath the nuclear envelope, disassembles under various abiotic stresses, modulating changes in three-dimensional genome organization and gene transcription in stress response.
Cell cycle inhibitor SIAMESE-RELATED1 is identified as a key factor determining the ratio of pavement cells over stomata in response to drought, by terminating the bipotency of stomatal lineage ground cells.
A new method to quantify three masting components from individual tree-years has revealed that globally, masting is uncommon in tree species that depend on mutualist dispersers, with its distribution further mediated by climate and nutrient availability.
ABACUS2 Förster resonance energy transfer biosensors allow an unparalleled view of abscisic acid accumulations and depletions in living plants. Well-watered roots accumulate abscisic acid in growing cells upon shoot dehydration and this is essential to maintain root growth under low humidity.
NAL1 is a breeding-valuable pleiotropic gene in rice. This study identifies NAL1 as a bona fide serine protease which degrades OsTPR2, thus modulating the expression of downstream genes related to hormone signalling pathways, eventually achieving its pleiotropic physiological functions.
The number of glucan chains in the cellulose microfibril of wood has long been debated. X-ray and NMR techniques show that the number is 24. Each microfibril has a dense crystalline core surrounded by a semidisordered shell and remains segregated in new wood.
Climate change will reduce seagrass ranges leading to increased endemism. Such changes will cause differentiation in some regions and homogenization in other areas. The current marine protected areas will be insufficient to protect seagrasses.
Zhao et al. have developed a method to detect and quantify single molecules of RNA in several intact plant tissues. The method can also be used to simultaneously quantify and locate mRNAs and proteins in single cells with subcellular resolution.
The nitrogen-fixing root nodule symbiosis evolved more than 90 million years ago. This innovation emerged by rewiring existing genetic programmes. More recently, this symbiosis convergently gained evolutionary stability in two legume lineages.
