OsCPN10a, cooperating with OsCPN20 and OsHSP60‐3B negatively regulate ABA signaling and enhance seed storability in rice

Journal of Integrative Plant Biology, EarlyView.
Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

Effect of temperature on pollen germination for several Rosaceae species: influence of freezing conservation time on germination patterns [PDF]

PeerJ, 2019
Between February 2018 and April 2018, flowers were collected from eight Rosaceae species. Flowers were kept in a freezer at −20 °C for three freezing times (Treatment 1, two months; Treatment 2, four months; Treatment 3, six months).

Dehydration‐driven organization of metabolites into NaDES‐like assemblies in orthodox seeds

New Phytologist, EarlyView.
Summary Desiccation tolerance in plants, especially during orthodox seed dehydration, relies on compatible solute accumulation, complex molecular mechanisms, and intermolecular organizations that remain poorly understood. We combined metabolite profiling, mass spectrometry imaging, and electrospray and cold‐spray ionization mass spectrometry to ...

Viability of eggplant pollen [PDF]

Crop Breeding and Applied Biotechnology, 2009
This study aimed to test methodologies to evaluate the pollen viability of eggplant. The pollen germinationwas tested in vitro, incubating the pollen during 0.5 and 16 hours in different sucrose concentrations (0; 2.5; 5.0; 7.5 and10.0 g L-1). For the in

Technique for In Vitro Pollen Germination and Short-term Pollen Storage in Caladium [PDF]

HortScience, 2004
The sporadic nature of inflorescence production and flower protogyny in caladium (Caladium ×hortulanum Birdsey) makes it desirable to store pollen and to rapidly assess its viability for cross-pollinations in breeding programs. This study was conducted to develop a procedure to determine caladium pollen viability and to use that procedure to evaluate ...

Multi‐Omics Combined With Mitochondrial Feeding Assays Reveal a Novel Energy Metabolism Strategy for Floral Thermogenesis in Magnolia Driven by Synergistic Supply of Multiple Substrates

Plant Biotechnology Journal, EarlyView.
ABSTRACT The high demand for energy during floral thermogenesis drives the synergistic operation of multiple energy substrates for the rapid temperature rise and successful reproduction of flowers. However, how thermogenic plants precisely regulate substrate supply and metabolic pathways within a short time to support large‐scale energy and heat ...

Morphology and viability of pollen grains from passion fruit species (Passiflora spp.)

Acta Botânica Brasílica, 2013
The characterization and viability of pollen grains are useful tools to guide crosses in breeding programs. The objective of this study was to describe the morphological patterns and viability of pollen grains from five accessions of Passiflora edulis f.
