Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Silver fir seed viability varies with age, fir‐associated forest cover and abiotic conditions of seed harvest stands across Austria

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
As climate change, habitat loss and fragmentation intensify, seed‐sourcing strategies should explicitly incorporate ecological filters when selecting stands for seed harvest to safeguard seed viability and genetic diversity for nursery production. Seed stand management should be refocused on promoting structural conditions that enhance reproductive ...

Comparative Studies on Fertility Traits of CMS Eggplants (Solanum melongena L.) Using Cytoplasms from Five Wild Solanum Species

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Five cytoplasmic male sterile (CMS) lines of eggplant “Uttara” (Solanum melongena L.) with the cytoplasms of S. kurzii (KUR), S. violaceum (VIO), S. aethiopicum (AET), S. anguivi (ANG), and S. grandifolium (GRA) and three restorers of fertility (RF) lines of CMS from AET, ANG, and GRA were compared for the fertility traits to determine which CMS are ...

Artificial Mutations in the Nuclear Gene Encoding Mitochondrial RNA Polymerase Restore Pollen Fertility in Cytoplasmic Male Sterile Tomato

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1414-1427, March 2026.
ABSTRACT Cytoplasmic male sterility (CMS) and restorer of fertility (Rf) are important traits in F1 hybrid breeding. However, the CMS/Rf system has not been used in tomatoes because of the limited resources of Rf lines. In this study, we performed mutagenesis in tomato CMS seeds and successfully obtained 13 suppressor mutants with pollen fertility ...

Anatomy and fruit development in Schinopsis balansae (Anacardiaceae)

Anales del Jardín Botánico de Madrid, 2010
Schinopsis balansae Engl. is a dioecious tree; reproduction is by woody samaras containing a single seed. Fruit set is high, even in isolated trees, empty fruits are frequent and account for a high proportion of the total fruit production.

“Bud to bloom”—hormonal coordination in floral initiation

Plant Biology, Volume 27, Issue 7, Page 1271-1284, December 2025.
This review unpacks hormonal networks in flower development, revealing how ‘bud to bloom’ transitions shape yield and plant resilience. Abstract Hormones have a dominant role in shaping the destiny of plant reproduction. Recent breakthroughs in our understanding of hormone function during floral development have revealed the pivotal roles of cytokinin,
