- Abstract:
- ... This study compared the effects of shading in individual branch orders 2 and 3 on the needle survival, growth, and reproduction of five categories of short shoots of the proximal part of wild Atlas cedar (Cedrus atlantica (Endl.) G. Manetti ex Carrière). The sun exposure did not affect the number of short shoots in the two branch orders, whereas light compared to shade only stimulates the unbranch ...

- Abstract:
- ... Climate change is driving species' range shifts, which are in turn disrupting species interactions due to species‐specific differences in their abilities to migrate in response to climate. We evaluated the consequences of asynchronous range shifts in an alpine plant–pollinator community by transplanting replicated alpine meadow turfs downslope along an elevational gradient thereby introducing them ...

Sperm cells in angiosperms are immotile and are physically distant to the female gametophytes (FG). To secure the production of the next generation, plants have devised a clever approach by which the two sperm cells in each ...

Graphene related materials (GRMs) are currently being used in products and devices of everyday life and this strongly increases the possibility of their ultimate release into the environment as waste items. GRMs have several effects on plants, and graphene oxide (GO) in particular, can affect pollen germination and tube growth due to its acidic properties. Despite the socio-economic importance of ...

- Abstract:
- ... Nectar robbing – harvesting nectar illegitimately – can have a variety of outcomes for plant sexual reproduction and for the pollinator community. Nectar robbers can damage flowers while robbing nectar, which could affect the behavior of subsequent flower visitors and, consequently, plant reproduction. However, only nectar manipulation by nectar robbers has so far received attention. We found a sh ...

Although lily is an internationally valued ornamental plant, its SE technology is still incomplete.

- Abstract:
- ... The key process of sexual reproduction is the successful fusion of the sperm and egg cell. Distinct from dynamic and flagellated animal sperm cells, higher flowering plant sperm cells are immotile. Therefore, plants have evolved a novel reproductive system to achieve fertilization and generate progenies. Plant sexual reproduction consists of multiple steps, mainly including gametophyte development ...

- Abstract:
- ... Breeding strategies for plants focus on the genetic influence on their phenotypes. However, the phenotype is not only the outcome of the genotype or the environmental conditions under which plants grow. It is important to also recognise that the maternal environment has a significant effect on the phenotype of the offspring. These maternal effects represent a transgenerational form of phenotypic p ...

As knowledge of ecological interactions between flowers and their microbial communities (the anthosphere) expands, it becomes increasingly important to consider the evolutionary impacts of these associations and their potential eco‐evolutionary dynamics. In this Viewpoint we synthesize current knowledge of ...

Oil-producing flowers have evolved specialized traits along with the ability to secrete oil as reward, leading to the expectation of a narrow relationship between floral architecture and oil-collecting behaviours of pollinators. Krameriaceae flowers have a showy calyx and a less conspicuous dimorphic corolla modified into a pair of elaiophores that secrete the oil, and a group of petaloid petals t ...

- Abstract:

Sexual plant reproduction is a strategy that allows plant populations to increase genetic variability, and consequently to be more efficient in adapting to new environments and to overcome stress conditions. Here, we focus on the reproductive mode of Phragmites australis, an important sub-cosmopolite species that can spread both by clonal propagation and sexual reproduction. In Europe, P. australi ...

- Abstract:
- ... Quantifying the benefits of pollinator abundance and diversity for plant reproduction is a critical challenge, especially given recent pollinator declines. Many studies test for pollen limitation (PL), but huge gaps remain in our understanding of how often and why plants experience PL. Most studies are limited to a few sites or years. Little existing research mechanistically links pollinator visit ...

- Abstract:

The lifetime of papilla cells is tightly controlled, and the developmental PCD (dPCD) process is involved in papilla cell death. Hence, papilla cell death is a good model for studying on PCD process. In this study, the dPCD signal was visuali ...

We tested whether traits that are easily-measured in the ...

Furthermore, the different units (metamers) that comprise plant bodies are not identical copies, but vary extensively within individuals. These characteristics foster recognition of plant phenotypes a ...
