In Vitro Studies on Pollen Viability, Pollen Germination and Pollen Tube Growth of Hornstedtia Conoidea Ridl. – a Philippine Endemic Ginger Species [PDF]

open access: yes, 2018
Zingiberaceous plants are predominantly propagated through underground rhizomes and seeds. In this study, the viability of pollen, rate of pollen germination and length of pollen tube of the Philippine endemic Hornstedtia conoidea were examined.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Reinstatement of the name Anisochilus eriocephalus Benth. (Lamiaceae) supported by micromorphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
In 2019, A. J. Paton et al. proposed a new taxonomic combination, transferring Anisochilus carnosus (L.f.) Wall. ex Benth. to Coleus strobilifer (Benth.) A.J.Paton, and including Anisochilus eriocephalus Benth. within this broader circumscription.

Combined cytological and transcriptomic analysis reveals a nitric oxide signaling pathway involved in cold-inhibited Camellia sinensis pollen tube growth

open access: yesFrontiers in Plant Science, 2016
Nitric oxide (NO) as a signaling molecule plays crucial roles in many abiotic stresses in plant development processes, including pollen tube growth. Here, the signaling networks dominated by NO during cold stress that inhibited Camellia sinensis pollen ...

Pollen-specific pectin methylesterase involved in pollen tube growth

open access: yesDevelopmental Biology, 2006
Pollen tube elongation in the pistil is a crucial step in the sexual reproduction of plants. Because the wall of the pollen tube tip is composed of a single layer of pectin and, unlike most other plant cell walls, does not contain cellulose or callose, pectin methylesterases (PMEs) likely play a central role in the pollen tube growth and determination ...

Unraveling cryptic lineages in Jatropha nana: phylogenetic evidence supports species status for J. benghalensis (Euphorbiaceae)

open access: yesNordic Journal of Botany, EarlyView.
The taxonomic framework of the genus Jatropha (Euphorbiaceae) is well established, but its geophytic species present significant classification challenges. These difficulties arise from species complexes, cryptic traits, and high environmental and phenotypic variability.
