Excess endopolyploidy associated with cellular defects in neo‐autotetraploid Arabidopsis arenosa is in part corrected by a naturally evolved allele of CYCD3;2

New Phytologist, EarlyView.
Ploidy level distributions and endoreduplication profiles in diploid and tetraploid Arabidopsis arenosa. Summary Endopolyploidy (within‐organism polyploidy) is an often‐beneficial aspect of development. But polyploids, which have a higher baseline genome content, have been reported to have less endoreduplication than diploid relatives. Why has remained

Rice bZIP11 acts as a transcriptional repressor that negatively regulates photosynthesis in response to nitrogen deficiency

New Phytologist, EarlyView.
Phenotypes of 43‐d‐old wild‐type (WT), Osbzip11‐KO, and OsbZIP11‐OX seedlings grown under control N and low N conditions. Summary Nitrogen (N)‐deficiency responses, which are closely linked to plant biomass and crop yield, differ between plant tissues.

Speciation and biogeographical history in the European Alpine System: the radiation of Ranunculus sect. Euromontani (Ranunculaceae)

New Phytologist, EarlyView.
Biogeographical analysis of species of Ranunculus sect. Euromontani and related taxa. Summary High mountain systems provide manifold preconditions for allopatric and sympatric speciation. We hypothesize that allopatric speciation due to geographical isolation of mountain chains, and sympatric speciation via allopolyploidy played major roles for a ...

Cortical lacunae, not xylem embolism, drive interspecific differences in freeze–thaw hydraulic dysfunction of conifer fine roots

New Phytologist, EarlyView.
Yellow‐cedar has experienced widespread decline as climate change reduces the snowpack that insulates its roots, but the mechanism of injury is unknown. We tested two competing hypotheses in roots of four conifers: loss of xylem conductivity from freeze‐thaw embolism, or loss of radial conductivity from direct freezing injury that forms cortical ...

Identification of auxin response factor ARF27 as a regulator of maize root morphogenesis

New Phytologist, EarlyView.
Working model for Zea mays ARF27 mediated primary root growth in maize Summary Auxin is a central phytohormone that mediates root development. This study investigated the genetic basis of auxin‐mediated primary root growth in Zea mays (maize) seedlings, which is not well‐understood in this key cereal crop.

A High‐Throughput Phenotyping Pipeline for Quinoa (Chenopodium quinoa) Panicles Using Image Analysis With Convolutional Neural Networks

Plant Breeding, EarlyView.
ABSTRACT Quinoa is a grain crop with excellent nutritional properties that has attracted global attention for its potential contribution to future food security in a changing climate. Despite its long history of cultivation, quinoa has been improved little by modern breeding and is a niche crop outside its native cultivation area.
