Effect of plant population on crop growth, floral biomass, and cannabinoid yield in field‐grown hemp

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Hemp (Cannabis sativa L.) was recently re‐legalized in the United States and cultivated for various purposes, including floral cannabidiol (CBD), grain, and fiber. Due to prohibition of hemp for a century, research supporting production guidelines, including plant density effects on CBD production, remains limited.

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Association mapping for hop cone chemistry and morphology identifies natural beneficial allele stacks

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Efforts are underway to increase the efficiency and precision of selection hop (Humulus lupulus L.) breeding using genomics. Little is known, however, about the genetic control of important traits like α‐and β‐acids contents, oil content, and cone morphological characteristics, all of which play an important role in determining the utility and

Morphology of glandular trichome and lignin-based structure for its function

Fundamental Research
Glandular trichomes play critical roles in plant defense, pollination, and environmental adaptation through the synthesis, storage, and secretion of a diverse range of compounds, including specialized metabolites and inorganic compounds.

Transcriptome assemblies for two drug‐type cannabis chemotypes by long‐read RNA sequencing

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Cannabis sativa has undergone over 10,000 years of domestication, resulting in extensive genetic and phenotypic diversity among cultivated chemotypes. Increased medical and recreational use of specialized metabolites accumulating in cannabis glandular trichomes—primarily the cannabinoids ∆9‐tetrahydrocannabinol (THC) and cannabidiol (CBD)—has ...

Genetic Diversity, Population Structure, and Environmental Influences in Nepeta glomerulosa: Implications for Conservation in the Irano‐Turanian Region

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Nepeta glomerulosa shows moderate genetic diversity with three main clusters and significant admixture, highest in the Alborz Mountains, suggesting it may be the center of origin. High genetic differentiation (Gst = 0.4199) points to limited gene flow and possible self‐pollination, with geographic isolation shaping population structure.
