The Endosperm of Angiosperms [PDF]
Botanical Gazette, 1911 In a recent analysis of all the available testimony in reference to the morphological nature of the endosperm of angiosperms, it seemed clear that certain conclusions might be reached, and the purpose of the present paper is to state them. It has been assumed that the endosperm must be either gametophytic tissue or sporophytic tissue, and the arguments

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture
PLANTS, PEOPLE, PLANET, EarlyView.Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Cadmium accumulation dynamics in the rice endosperm during grain filling revealed by autoradiography
Plant DirectCadmium (Cd) is one of the environmental pollutants contaminated in our food. Several previous reports showed that rice polishing cannot be efficient to reduce Cd content in white rice, implying the characteristic Cd distribution in rice grain.

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

PLANTS, PEOPLE, PLANET, EarlyView.Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.

Injectable Zein‐Based Photothermal Composite Hydrogel Enhances Osteoporotic Tendon–Bone Healing
Small Methods, EarlyView.Schematic illustration of the Zein‐based, dopamine‐grafted, niacin‐loaded carbon nanosphere (ZDC) composite hydrogel for enhancing healing of osteoporotic rotator cuff tears. This electron beam‐modified composite hydrogel is designed for NIR‐responsive release of niacin, which alleviates inflammation, promotes angiogenesis, and facilitates the ...

Light microscopical study of endosperm formation in Brassica napus L.
Acta Societatis Botanicorum Poloniae, 2014 The cellularization of the endosperm of Brassica napus was investigated with light microscopy after embedment in Technovit 7100. The microtubular cytoskeleton was visualized by immunofluorescence techniques after embedment in butyl methyl metacrylate ...

Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1
The FEBS Journal, EarlyView.In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

MicroRNAs Regulate Grain Development in Rice
AgronomyEnsuring food security is a challenge for humans. Rice grain yield and quality must urgently be increased to overcome this challenge. MicroRNA (miRNA) is an important regulatory module in plant development and stress responses.

Towards the Understanding of Important Coconut Endosperm Phenotypes: Is there an Epigenetic Control?
Agronomy, 2018 The coconut is a major crop of many tropical countries, with the endosperm being one of its main products. The coconut soft-endosperm variants, the Makapuno and the Lono, are emerging as economically important.
