California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

Journal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Jasmonate biosynthesis regulates key events in barley vegetative and reproductive development

New Phytologist, EarlyView.
Generation and general phenotypes of hvaoc mutants. Summary Cereal grain is a global food staple. Filial tissues in grain, such as the embryo and endosperm, grow embedded in the maternal ovule and surrounding ovary wall. Maternal tissues provide nutrition and protection but are progressively reduced and degraded as filial tissues expand, driving grain ...

Apis mellifera (Hymenoptera: Apidae) as a potential Brassica napus pollinator (cv. Hyola 432) (Brassicaceae), in Southern Brazil Apis mellifera (Hymenoptera: Apidae) como potencial polinizador de Brassica napus (cv. Hyola 432) (Brassicaceae), no Sul do Brasil

Brazilian Journal of Biology, 2010
Brassica napus Linnaeus is considered a self-compatible crop; however, studies show that bee foraging elevates their seed production. Considering bee food shortages during the winter season and that the canola is a winter crop, this study aimed to ...

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Harnessing genetic variation for grain quality from diverse wheat landraces

New Phytologist, EarlyView.
Grain protein content is usually measured on bulk samples, hiding variation between individual grains. We used hyperspectral imaging to predict protein in c. 15 000 single grains from over 500 Watkins wheat landraces grown in two environments, resolving both mean protein content and grain‐to‐grain uniformity.

Soil Zinc Availability Alters the Contribution of Pre-Anthesis and Post-Anthesis Uptake in Rice Grain Zinc Loading

Journal of Agriculture and Biology
Rice (Oryza sativa L.) is the most crucial cereal globally and serves as a vital source of zinc (Zn) for individuals whose diets are primarily rice-based. To improve the Zn content in rice, it is essential to gain a deeper understanding of how plants absorb and distribute zinc internally.

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

Metabolomics of Flower Anthesis

, 2019
How metabolism changes during development and what drive those changes are open questions in flower biology. During flower development, the onset of anthesis is a time of remarkable transformations: petals 16 unroll and stretch out, style and filaments ...
