An overview on reproductive isolation in Oryza sativa complex

Reproductive isolation is generally regarded as the essence of the speciation process. The evolution of reproductive isolation allows differentiation and permits local adaptations to become fixed

Sex and the flower – developmental aspects of sex chromosome evolution

Separate sexes and sex chromosomes evolved independently many times in plants. As well as the XY system humans have, some plants have a ZW system. But

Abscisic acid (ABA) and low temperatures increase cold-hardiness in grapevine dormant buds

It has been reported that low temperatures and the plant hormone abscisic acid (ABA) induce the expression of CBF/DREB1 transcription factors in vegetative tissues and

Cross-disciplinary research needed to unleash the potential of plant morphology

There were many great articles concerning cross-disciplinary research at the interface between plant biology, mathematics and computer science before the launch in silico Plants (isP). We are excited for isP to be home to these types of articles in the future.

Botanists see the start of tropicalisation

With climate change, plants start colonising new areas, but how will new regions become tropical? A new study hints at the start of the process.

In vitro axenic germination and cultivation of mixotrophic Pyroloideae (Ericaceae)

Pyroloids, forest sub-shrubs of the Ericaceae family, are an important model for their mixotrophic nutrition, which mixes carbon from photosynthesis and from their mycorrhizal fungi.

Thirty clues to the exceptional diversification of flowering plants

As angiosperms became one of the megadiverse groups of macroscopic eukaryotes, they forged modern ecosystems and promoted the evolution of extant terrestrial biota. Unequal distribution of

Soil fertility and flood regime are correlated with phylogenetic structure of Amazonian palm communities

Identifying the processes that generate and maintain biodiversity requires understanding of how evolutionary processes interact with abiotic conditions to structure communities. Edaphic gradients are strongly associated

How repeatable is microevolution on islands?

Archipelagos provide a valuable framework for investigating phenotypic evolution under different levels of geographical isolation. García-Verdugo et al. analysed two co-distributed, widespread plant lineages

Association between community assemblage of flower colours and pollinator fauna

Flower colour plays a major role in the attraction and decision-making of pollinators. Different functional groups of pollinators tend to prefer different flower colours, and

Exploration of cotton leaf curl virus resistance genes in Gossypium arboretum

Cotton leaf curl virus (CLCuV) is one of the major limiting factors in cotton production systems worldwide. The widely cultivated cotton species, Gossypium hirsutum, is particularly

Auxin transport and stem vascular reconnection – has our thinking become canalized?

The presence of a polar auxin transport stream has long been correlated with the differentiation and patterning of vascular cells across vascular plants. As our understanding
