Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

open access: yesInsect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Lantana delicata (Verbenaceae), a New Species From Brazil, and Additional Updates Within the Genus

open access: yesFeddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT In this study, we present some novelties in Lantana, a taxonomically complex genus of Verbenaceae. These include (1) the description of L. delicata, a new species from Brazil; (2) the lectotypification of the name L. magnibracteata; and (3) the recognition of L. fucata f. albiflora, previously regarded as a synonym of L.

Genome‐Wide Identification of YABBY Genes in Medicago truncatula Reveals a Role for MtYAB3 in Petal Lateral Expansion

open access: yesLegume Science, Volume 8, Issue 3, September 2026.
ABSTRACT YABBY transcription factors are plant‐specific regulators of lateral organ development, yet their functions in legume flower morphogenesis remain poorly understood. Here, we identified seven YABBY genes in the Medicago truncatula genome and assigned them to five conserved subfamilies.

The location of nectaries and nectar secretion in the flowers of Allium giganteum Regel

open access: yesActa Agrobotanica, 2012
In the flowers of Allium there are found septal nectaries; in particular species, their outlet can be located in different parts of the ovary. The inflorescences of these plants are a rich source of nectar for insects.

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.

Identification of differential gene expression in Brassica rapa nectaries through expressed sequence tag analysis. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Nectaries are the floral organs responsible for the synthesis and secretion of nectar. Despite their central roles in pollination biology, very little is understood about the molecular mechanisms underlying nectar production. This project was

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1407-1418, September 2026.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Extrafloral nectaries of some australian bipinnate acacias

open access: yes, 1985
The extrafloral nectaries of some Australian bipinnate Acacia species are examined, coming from three sections: Acacia (two species); Botrycephalae (27 species); and Pulchellae (12 species).

Pollinator Associations of Rare and Endangered Epacris Species (Ericaceae) in Lutruwita/Tasmania: Implications for Conservation

open access: yesAustral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral
