Lacandonia granules are present in the cell nucleus of Welwitschia mirabilis
Botanical Sciences, 2018 Background: Lacandonia granules are extranucleolar ribonucleoprotein (RNPs) particles, 32 nanometers in diameter that were first described in the nucleus of Lacandonia schismatica. Cytochemical and immunocytochemical studies suggest that these particles

Applications in Plant Sciences, EarlyView.Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants. [PDF]
New PhytolSummary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

Early evolutionary history of the seed. [PDF]
Biol Rev Camb Philos SocABSTRACT 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 ...

A cost‐effective DNA extraction protocol for long‐read sequencing in non‐model plants
Applications in Plant Sciences, EarlyView.Abstract Premise Third‐generation sequencing has revolutionized genomics, enabling in‐depth analysis of genome sequence, structure, and epigenetic features. Yet, extracting high‐quality DNA for long‐read sequencing remains a bottleneck—particularly in non‐model plants, such as mature trees growing in natural environments, which often contain abundant ...

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status
Nordic Journal of Botany, EarlyView.Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges
Oikos, EarlyView.Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.
