California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

Journal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Not Only Hummingbirds: Reproductive Biology and Pollinators of the High-Andean Endangered Puya raimondii (Bromeliaceae)

International Journal of Plant Biology
Puya raimondii, an endangered high-Andean species, exhibits life-history traits that may strongly influence its reproductive strategy; however, its reproductive biology remains poorly understood. Here, we assessed its floral biology, breeding system, and

Pollination by native bees increases fruit mass without changing protein content in snap beans [PDF]

Scientia Agricola
: Insects play a vital role in agricultural production by enhancing both the quantity and quality of fruits and seeds in a wide range of allogamous and autogamous crops. The common bean (Phaseolus vulgaris) exemplifies an autogamous crop that can benefit

Genetic Dissection of Wheat Heterosis Identifies Candidate Genes in Biparental and Diverse Hybrid Populations

Plant Biotechnology Journal, EarlyView.
ABSTRACT Understanding how numerous heterotic quantitative trait loci (hQTL) shape heterosis and shifting from hQTL to candidate genes are central challenges. To address these challenges, we performed a systematic, genome‐wide mapping in a biparental population and a population of diverse hybrids.

Analysis of the reproduction mode in Psidium spp. using the pollen:ovule ratio

Acta Scientiarum. Agronomy, 2020
This research aimed to explore the reproductive characteristics of three species of Psidium (P. guajava L., P. cattleyanum Sabine, and P. guineense Sw.) and estimate a probable reproduction strategy based on the pollen:ovule (P:O) methodology.

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Is there a hybridization barrier between Gentiana lutea color morphs? [PDF]

PeerJ, 2015
In Gentiana lutea two varieties are described: G. lutea var. aurantiaca with orange corolla colors and G. lutea var. lutea with yellow corolla colors. Both color varieties co-occur in NW Spain, and pollinators select flower color in this species.

Advances in the Integration of Genomic and Phenomic Tools in Cowpea Breeding for Improving Stress Resilience and Grain Yield and Quality

Legume Science, Volume 8, Issue 4, December 2026.
ABSTRACT Cowpea (Vigna unguiculata L. Walp) is a multi‐use crop highly valued as a food crop, high‐protein fodder, and sustainable cover crop. Yet, it remains underused, and yields in most growing regions are below the crop's potential due to multiple biotic and abiotic stresses.

Preferential reproduction mode of hermaphrodite papaya plant (Carica papaya L; Caricaceae) Modo de reprodução preferencial de plantas hermafroditas de mamoeiro (Carica papaya L; Caricaceae)

Revista Brasileira de Fruticultura, 2009
This research was done to study the reproductive system of papaya hermaphrodite plant based on the histochemical nature of pollen grain, stigma receptivity, in vivo pollen grain germination and pollen:ovule ratio.

Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

Pest Management Science, Volume 82, Issue 10, Page 10303-10311, October 2026.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.
