Psychotria caraballoensis (Rubiaceae), a new species from northern Luzon, Philippines

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
In this paper, we describe and illustrate Psychotria caraballoensis, a new endemic species from the Caraballo Mountain Range, Luzon, Philippines. It is allied to the Subalpina species group sensu Sohmer and Davis (2007), and resembles Psychotria sohotonensis.

Sex-Specific Responses of Sexual Reproduction, Clonal Reproduction, and Vegetative Growth to Environmental (Biotic and Abiotic) Factors in the Clonal Dioecious Plant Acer barbinerve

Plants
Sexual dimorphism in dioecious plants serves as a critical adaptive strategy in complex environments. This study systematically investigated the effects of topographic factors (elevation, slope, aspect, and convexity), soil nutrients (C, N, P), and ...

Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

TAXON, Volume 75, Issue 1, February 2026.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

Sex-Specific Differences in the Physiological and Biochemical Performance of Arbuscular Mycorrhizal Fungi-Inoculated Mulberry Clones Under Salinity Stress

Frontiers in Plant Science, 2021
Arbuscular mycorrhizal fungi (AMF) are often considered bioameliorators. AMF can promote plant growth under various stressful conditions; however, differences between male and female clones in mycorrhizal strategies that protect plants from the ...

Cosexuality Reduces Pollen Production and Fitness in Cannabis sativa L.

Plants, 2023
Cannabis sativa L. is cultivated globally for its cannabinoid-dense inflorescences. Commercial preference for sinsemilla has led to the development of methods for producing feminized seeds through cross-pollination of cosexual (masculinized) female ...

The quest for molecular regulation underlying unisexual flower development [PDF]

, 2016
The understanding of the molecular mechanisms responsible for the making of a unisexual flower has been a long-standing quest in plant biology. Plants with male and female flowers can be divided mainly into two categories: dioecious and monoecious, and ...

Nucleo-Cytoplasmic Male Sterility and Alternative Routes to Dioecy [PDF]

Evolution, 1994
Population-genetic models of nucleo-cytoplasmic gynodioecy are shown to allow invasion of males and conversion to dioecy in a single cytotype. Pleiotropic effects of restorer alleles on fertility through male or female function can maintain a cytoplasmic polymorphism in a population that prevents evolution to dioecy regardless of the pollen fertility ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Toward an art of genomic selection in vegetable breeding

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract Genomic selection (GS) is a powerful strategy for accelerating genetic gain in plant breeding. While in recent years GS has been widely adopted in breeding programs for agronomic crops, its implementation in vegetable breeding has been comparatively limited.
