Rediscovery of Strobilanthes panichanga and discovery of Strobilanthes parryorum (Acanthaceae): two endangered species from the hills of Dima Hasao, Assam, India

Nordic Journal of Botany, EarlyView.
We report on two species of Strobilanthes Blume. Strobilanthes panichanga (Nees) T.Anderson has been rediscovered in the Dima Hasao district of Assam, India, after a very long gap of 150 years, and Strobilanthes parryorum C.E.C.Fisch has been discovered for the first time in Assam, India.

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

Nordic Journal of Botany, EarlyView.
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.

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments

, 2009
TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Floral biology and propagation of blue-flowered Conospermum spp

, 2003
Blue-flowered Conospermum are endemic to Western Australia, and show great potential as cut flowers. Propagation from cuttings or seed proved difficult, and root initiation in vitro is problematic. This thesis examines the floral biology of the species

Multifaceted obscurity of Thismia abei (Thismiaceae): A fairy lantern with the protologue long disregarded in practice

PLANTS, PEOPLE, PLANET, EarlyView.
Tiny, leafless fairy lanterns are easily overlooked on the forest floor. Thismia abei, endemic to Japan, persists in small, unstable populations and is listed nationally as Critically Endangered. Our recent work has revealed another, less obvious form of obscurity.

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

Pest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.

EFFECT OF DIFFERENT FACTORS ON GERMINATION AND TUBE GROWTH OF Solanum sisymbrifolium LAM. POLLEN

Annals of Tropical Research, 1988
Both germination and tube growth of Solanum sisymbrifolium Lam. pollen require an optimum temperature of 25°C and a growth medium containing 100 ppm boric acid, 10% sucrose and 0.6% Bacto-agar. Pollen germination was stimulated by 5 and 10 ppm GA3, 1-10
