Floral and reproductive biology and pollinators of Campomanesia guazumifolia (Cambess.) O. Berg., neglected species

open access: yesActa Scientiarum: Biological Sciences, 2021
Studies on the Myrtaceae family are mainly distributed in floristic surveys, reproductive studies of plant communities or related to family taxonomy. Based on this, the objective of the present study was to elucidate aspects of floral and reproductive ...

Uncovering the Arabidopsis thaliana nectary transcriptome: investigation of differential gene expression in floral nectariferous tissues

open access: yesBMC Plant Biology, 2009
Background Many flowering plants attract pollinators by offering a reward of floral nectar. Remarkably, the molecular events involved in the development of nectaries, the organs that produce nectar, as well as the synthesis and secretion of nectar itself,

Diversity of the floral nectaries surface of four Crataegus L. species

open access: yesActa Agrobotanica, 2012
The performed studies focused on the surface structure of floral nectaries of four species from the following genus: C. coccinea L. , C. crus-galli L., C. curvisepala Lindm and C. prunifolia (Poiret) Pers. The observations of the epidermis area were made

Flowering, nectar secretion, and structure of the nectary in the flowers of Acer pseudoplatanus L.

open access: yesActa Agrobotanica, 2019
Flowering and nectar release in Acer pseudoplatanus were investigated between 2011 and 2013. The micromorphology of the floral and nectary elements was observed using a scanning electron microscope and the anatomy of nectaries was examined by light ...

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Sinningia pampeana sp. nov. (Gesneriaceae) from the Pampa's rocky outcrops in southern Brazil and Uruguay

open access: yesNordic Journal of Botany, EarlyView.
Sinningia pampeana is a new rupicolous species from the rocky outcrops of the Pampa biome in southern Brazil and Uruguay. Morphological analyses based on herbarium material, field observations, and detailed illustrations support its recognition as a distinct species from Sinningia sellovii.
