Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

open access: yesNordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Typification and rediscovery of Phialacanthus griffithii Benth. & Hook.f. (Acanthaceae) in Arunachal Pradesh, India

open access: yesNordic Journal of Botany, EarlyView.
Phialacanthus griffithii Benth. & Hook.f. (Acanthaceae), a species long thought unrecorded, was rediscovered in 2023 after a 160‐year gap in the Upper Dibang Valley, Eastern Himalaya, Arunachal Pradesh. The study presents a comprehensive taxonomic account including lectotypification, morphological description, phenology, habitat ecology, distribution ...

Oreocharis konkakinhensis (Gesneriaceae) sp. nov. from the Central Highlands, Vietnam

open access: yesNordic Journal of Botany, EarlyView.
Oreocharis konkakinhensis, a new species of Gesneriaceae, is described and illustrated from the Central Highlands, Vietnam. The new species is morphologically most similar to Oreocharis phuongii, a recently described species from central Vietnam. However, it clearly differs from the latter by having stems without stolons, subulate bracts, yellow inner ...

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

open access: yesNew Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Hyperspectral signatures reveal hidden stress in soybean caused by residual nicosulfuron

open access: yesNew Plant Protection, EarlyView.
Residual nicosulfuron in soil triggers a distinct injury–regulation–collapse trajectory in soybean. Multimodal phenotyping combining hyperspectral, UV‐MCF, and chlorophyll fluorescence imaging enables early, non‐invasive detection and dynamic monitoring of latent herbicide stress, offering a mechanistic basis for risk assessment in crop rotation ...
