During evolution of land plants, the first colonizing species presented leafy-dominant
gametophytes, found in non-vascular plants (bryophytes). Today, bryophytes include …

Pollen grain is a unique haploid organism characterized by two key physiological
processes: activation of metabolism upon exiting dormancy and polar tube growth. In …

The acid deposition has been considered to be a severe environmental issue in China. The
pH, electrical conductivity (EC), and concentrations of water soluble ions (NO 3-, Cl-, Ca 2+ …

Plant cell wall remodeling plays a key role in the control of cell elongation and
differentiation. In particular, fine‐tuning of the degree of methylesterification of pectins was …

Tip-focused accumulation of reactive oxygen species (ROS) is tightly associated with pollen
tube growth and is thus critical for fertilization. However, it is unclear how tip-growing cells …

Several signaling pathways have been shown to be involved in the regulation of pollen
germination and pollen tube elongation. Among others, exogenously applied polyamines …

Key message The pollen tube is being subjected to control by a complex network of
communication that regulates its shape and the misfunction of a single component causes …

Pollen tube (PT) growth as a key step for successful fertilization is essential for angiosperm
survival and especially vital for grain yield in cereals. The process of PT growth is regulated …

Although pollen structure and morphology evolved toward the optimization of stability and
fertilization efficiency, its performance is affected by harsh environmental conditions, eg …

Arabinogalactan‐proteins (AGPs) are hydroxyproline‐rich glycoproteins containing a high
sugar content and are widely distributed in the plant kingdom. AGPs have long been …
