In arid and semi-arid areas, plants can directly absorb and use dew through their leaves, and some plants have the ability of hydraulic redistribution of their roots. Therefore, in arid areas, plants may redistribute dew to the soil, using the soil as a reservoir for short-term dry seasons, that is, dew may participate in the hydraulic redistributi...

Carnivorous plants trap and digest insects and similar-sized animals. Many studies have examined enzymes in the digestive fluids of these plants and have gradually unveiled the origins and gene expression of these enzymes. However, only a few attempts have been made at characterization of nucleases. This study aimed to reveal gene expression and st...

Climate-change induced warmer spring temperatures advance tree leaf-out and result in earlier shading of the forest floor. Climate change also leads to more frequent droughts. Forest understorey herbs may respond to these environmental changes by varying traits at different hierarchical levels of organisation. While trait mean variation at the inte...

The Early Devonian (Emsian, 400-395 Ma) tracheophyte Leptocentroxyla tetrarcha Bickner et Tomescu emend. Tomescu et McQueen combines plesiomorphic Psilophyton-type tracheid thickenings with xylem architecture intermediate between the plesiomorphic basal euphyllophyte haplosteles and the complex actinosteles of Middle Devonian euphyllophytes. We doc...

Asparagaceae subfamily Nolinoideae is an economically important plant group, however, the deep relationships and evolutionary history of the lineage remains poorly understood. Based on a large data set including 37 newly sequenced samples and publicly available plastomes, this study aims to better resolve the inter-tribal relationships of Nolinoide...

Seed cone traits are significant for understanding the evolutionary history of conifers. Podocarpaceae has fleshy cones with a distinct morphology compared with other conifers. However, we have a poor understanding of the seed cone morphology of the Prumnopityoid clade and within Podocarpaceae. This study presents detailed seed cone morpho-anatomy ...

Understanding how genetic diversity is distributed and maintained within species is a central tenet of evolutionary and conservation biology, yet is understudied in arid regions of the globe. In temperate, glaciated environments, high genetic diversity in plant species is frequently found in refugial areas, which are often associated with southern ...

Flower pigment and shape are determined by the coordinated expression of a set of structural genes during flower development. R2R3-MYB transcription factors are known regulators of structural gene expression. The current study focused on two members of this large family of transcription factors that were predicted to have roles in pigment biosynthe...

Despite many studies on the importance of competition and plants' associations with mutualists and pathogens on plant performance and community organization, the joint effects of these two factors remain largely unexplored. Even less is known about how these joint effects vary through a plant's life in different environmental conditions and how the...
