Frontiers in Plant Science, 2022 MicroRNAs (miRNAs) are key regulators of several plant developmental processes including embryogenesis. Most miRNA families are conserved across major groups of plant species, but their regulatory roles have been studied mainly in model species like ...

Crassoascus monocaudatus and Iodosphaeria podocarpi, two new species on Podocarpus parlatorei from [PDF]
Mycosphere, 2012 During a biodiversity study of micromycetes occurring on bark and decorticated wood of a native gymnosperm, Podocarpus parlatorei Pilg., from Argentina, new taxa of Crassoascus and Iodosphaeria were found.

Frontiers in Plant Science, 2021 Enormous distinctions of the stem structure and cell types between gymnosperms and angiosperms tree species are expected to cause quite different wood physical and mechanical attributes, however, the molecular mechanisms underlying the differing wood ...

A checklist of gymnosperm-feeding leafminers (Arthopoda, Insecta) in North America and Europe [PDF]
Biodiversity Data Journal, 2022 The leafminers on gymnosperms receive much less attention than those on either angiosperms or ferns. Given the distinctly different leaf shape and leaf venation found in gymnosperms, they would be expected to host significantly different leafminer groups.

Ecology and Evolution, 2022 Plastid genomes (plastomes) have a quadripartite structure, but some species have drastically reduced or lost inverted repeat (IR) regions. IR regions are important for genome stability and the evolution rate.

Plants, 2023 Climate change is one of the most prominent factors influencing the spatial distribution of plants in China, including gymnosperms. Climatic factors influence gymnosperm distribution along elevational gradients on the Qinghai–Xizang (Tibet) Plateau (QTP),

Central Cell in Flowering Plants: Specification, Signaling, and Evolution
Frontiers in Plant Science, 2020 During the reproduction of animals and lower plants, one sperm cell usually outcompetes the rivals to fertilize a single egg cell. But in flowering plants, two sperm cells fertilize the two adjacent dimorphic female gametes, the egg and central cell ...

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]
, 2014 Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is
