Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

Journal of Applied Entomology, Volume 150, Issue 3, Page 351-363, April 2026.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Evolutionary mobility and genetic dynamics of MORFFO genes: shuttling among ancient plant lineages

New Phytologist, Volume 250, Issue 2, Page 1248-1264, April 2026.
Summary Plastid genomes (plastomes) of land plants are characterized by their architectural and genic content stability. However, fern plastomes exhibit unexpected dynamism, characterized by the presence of mobile protein‐coding genes (CDS) – Mobile Open Reading Frames in Fern Organelles (MORFFOs). We investigate the evolutionary dynamics of MORFFOs in

When Are Cacti Found with Flowers and Fruits? Estimation of the Reproductive Phenology of the Genus Xiquexique Based on Herbarium Data

Diversity
Plant phenology reflects the reproductive responses of plants to seasonal cycles and climate change. Herbarium collections can be valuable tools for filling in gaps in phenological studies. We investigated the seasonality of the reproductive phenology of

Karyotype characterization and evolution of chromosome number in Cactaceae with special emphasis on subfamily Cactoideae [PDF]

Acta Botânica Brasílica, 2019
Cactaceae species are karyotypically well-known with x = 11 and chromosome number variation due mainly to polyploidization. However, both assumptions are based on descriptive observations without taking an evolutionary framework of Cactaceae into account.

Several plant self‐incompatibility systems may be controlled by atypical receptor–ligand interactions

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Self‐incompatibility (SI) is the single most important mechanism utilized by flowering plants to avoid self‐fertilization, thus preventing inbreeding and promoting outcrossing. Many plant SI systems are genetically controlled by a multi‐allelic S‐locus, containing two tightly linked genes that encode the female and male S‐determinants.

Dragon Fruit (Hylocereus undatus) Pollination in New Zealand: A Preliminary Report on Flower Visitors, Natural Pollen Deposition, and Artificial Pollination

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Dragon fruit (pitaya; Hylocereus undatus) is a promising, new high‐value crop in New Zealand. The large nocturnal flowers open for one night and close early in the morning the following day over a 3‐ to 6‐month long flowering period. In dragon fruit's native range, hawkmoths and bats are key nocturnal pollinators, and honey bees visit flowers during ...
