Flavonols stimulate development, germination, and tube growth of tobacco pollen.
The effect of anther-derived substances on pollen function was studied using pollen produced by in vitro culture of immature pollen of tobacco (Nicotiana tabacum L.) and petunia (Petunia hybrida). Addition of conditioned medium consisting of diffusates from in situ matured pollen strongly increased pollen germination frequency and pollen tube growth, as well as seed set after in situ pollinatio...
متن کاملNitric Oxide Participates in Cold-Inhibited Camellia sinensis Pollen Germination and Tube Growth Partly via cGMP In Vitro
Nitric oxide (NO) plays essential roles in many biotic and abiotic stresses in plant development procedures, including pollen tube growth. Here, effects of NO on cold stress inhibited pollen germination and tube growth in Camellia sinensis were investigated in vitro. The NO production, NO synthase (NOS)-like activity, cGMP content and proline (Pro) accumulation upon treatment with NO scavenger ...
متن کاملUse of Lilium longiflorum, cv. ace pollen germination and tube elongation as a bioassay for the hepatocarcinogens, aflatoxins.
Although various animal tissues are used for bioassay of aflatoxins (B1, B2, G1, G2), a rapid bioassay dependent upon a plant part's response does not exist. Both pollen germination (G) and tube elongation (TE) were enhanced in a 3.0 mM KH2PO4 (K)-containing but AFB1-lacking, modified Dickinson's medium. The B1 did not affect G when K was withheld but K supplementation impaired G above 15 micro...
متن کاملInterference of the Histone Deacetylase Inhibits Pollen Germination and Pollen Tube Growth in Picea wilsonii Mast
Histone deacetylase (HDAC) is a crucial component in the regulation of gene expression in various cellular processes in animal and plant cells. HDAC has been reported to play a role in embryogenesis. However, the effect of HDAC on androgamete development remains unclear, especially in gymnosperms. In this study, we used the HDAC inhibitors trichostatin A (TSA) and sodium butyrate (NaB) to exami...
متن کاملNanovesicles are secreted during pollen germination and pollen tube growth: a possible role in fertilization.
Dear Editor, During recent decades, a novel mechanism of secretion has been identified in a wide range of mammalian cells. It involves the release of bioactive membrane nanovesicles (30–100 nm), termed exosomes, upon the fusion of multivesicular bodies with the plasma membrane (Théry et al., 2009). Exosomes are implicated in diverse functions, such as scavenging of archaic proteins, intercellul...
