Seed lipid profiles of perennial ryegrass: Global patterns and differentiation of ryegrass cultivars and Epichloë endophytes

Grassland Research, EarlyView.
Seed lipid profiles from three ryegrass cultivars infected with AR501 show distinct changes in the medium‐chain diacylglycerols, triacylglycerols and sphingolipids. The differential peal LN745.5052_5.78 can be identified as PG 16:0_18:2 with the supporting ms2 fragmentation spectrum. Abstract Background Forage perennial ryegrass (Lolium perenne L.) has

Grazing reduces plant sexual reproduction but increases asexual reproduction: A global meta-analysis [PDF]

, 2023
Grazing affects grasslands worldwide. However, the global patterns and general mechanisms of how grazing affects plant reproductive traits are poorly understood, especially in the context of different climates and grazing duration.

Examining New Donors in the OECD's Development Assistance Committee

Journal of International Development, EarlyView.
ABSTRACT How do emerging donors integrate into the existing international aid architecture? While the existing literature focuses largely on emerging donors from the Global South, such as Brazil, China, India and Russia, there are many emerging donors from the Global North that have joined the OECD's Development Assistance Committee (DAC)—the premier ...

Hydroxamic Acids as HDAC Inhibitor Drug Leads for Malaria

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a global health threat, with an estimated 282 million cases and 610,000 malaria‐associated deaths reported in 2024. Most mortality is due to infection by Plasmodium falciparum parasites, with the highest burden occurring in Sub‐Saharan Africa.

The role of true viviparity in Amphibolis antarctica: implications for the genetic diversity in the context of seagrass restoration

Frontiers in Conservation Science
Amphibolis antarctica (Labill.) Asch. produces large, well-developed viviparous seedlings, raising a fundamental question: Are these seedlings the result of sexual or asexual reproduction?

Inhibition of asexual reproduction in planaria [PDF]

, 1969
Asexual reproduction in the decapitated planaria, Dugesia dorotocephala, is inhibited by an extract of homogenized heads of the same or closely-related species.

Habitat heterogeneity favors asexual reproduction in natural populations of grassthrips [PDF]

, 2016
Explaining the overwhelming success of sex among eukaryotes is difficult given the obvious costs of sex relative to asexuality. Different studies have shown that sex can provide benefits in spatially heterogeneous environments under specific conditions ...

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Reproduction-associated pathways in females of gibel carp (Carassius gibelio) shed light on the molecular mechanisms of the coexistence of asexual and sexual reproduction

BMC Genomics
Gibel carp (Carassius gibelio) is a cyprinid fish that originated in eastern Eurasia and is considered as invasive in European freshwater ecosystems. The populations of gibel carp in Europe are mostly composed of asexually reproducing triploid females (i.
