Rice, 2018 BackgroundPollen tube elongation in the pistil is a key step for pollination success in plants, and auxins play an important role in this process. However, the function of auxins in pollen tube elongation in the pistil of rice under heat stress has ...

Effects of temperature on pollen viability and in vivo pollen tube growth in Citrus sinensis
Journal of Applied Botany and Food Quality, 2022 Temperature is the major factor in global warming and strongly influences the success of plant sexual reproduction. Therefore, there isan urgent need to assess the vulnerability of species for breeding and planning effective actions.

Distinct short-range ovule signals attract or repel
BMC Plant Biology, 2006 Background Pollen tubes deliver sperm after navigating through flower tissues in response to attractive and repulsive cues. Genetic analyses in maize and Arabidopsis thaliana and cell ablation studies in Torenia fournieri have shown that the female ...

2, 6-Dichlorobenzonitrile causes multiple effects on pollen tube growth beyond altering cellulose synthesis in Pinus bungeana Zucc. [PDF]
PLoS ONE, 2013 Cellulose is an important component of cell wall, yet its location and function in pollen tubes remain speculative. In this paper, we studied the role of cellulose synthesis in pollen tube elongation in Pinus bungeana Zucc.

Genome-Wide Analysis of Cyclic Nucleotide-Gated Channel Genes Related to Pollen Development in Rice
Plants, 2022 In the angiosperm, pollen germinates and rapidly expands the pollen tube toward the ovule. This process is important for plant double fertilization and seed setting.

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis
Advanced Science, EarlyView.Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

Organization and Regulation of the Actin Cytoskeleton in the Pollen Tube
Frontiers in Plant Science, 2015 Proper organization of the actin cytoskeleton is crucial for pollen tube growth. However, the precise mechanisms by which the actin cytoskeleton regulates pollen tube growth remain to be further elucidated.

CrRLK1L receptor-like kinases HERK1 and ANJEA are female determinants of pollen tube reception
bioRxiv, 2018 Communication between the male and female gametophytes is vital for fertilisation to occur in angiosperms. A number of receptor-like kinases have been implicated in male-female interactions.

Maize Anther Development Involves Translated Open Reading Frames From 3′ Untranslated Regions
Advanced Science, EarlyView.This study examined the translation activity across ten stages of maize anther development, integrating transcriptome and small‐peptide data. It linked mutations in translated 3' ORFs to anther sterility, exemplified by Zm00001eb417050_3' ORF (known as APV1). In addition, the data indicated that maize anthers could assimilate CO2 through the stomata in
