Pollen biology and hormesis: Pollen germination and pollen tube elongation

open access: yesScience of The Total Environment, 2021
This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades. Hormetic doses responses were induced by a wide range of chemical and physical agents in 34 plant species for pollen germination and pollen tube growth/elongation.

In Vitro Pollen Germination of Eichhornia crassipes (Mart.) Solms: An Insight into its Preferred Mode of Clonal Reproduction

open access: yesNotulae Scientia Biologicae, 2012
Eichhornia crassipes (Mart.) Solms is an aquatic invasive weed throughout the tropical and subtropical regions of the world. The plant rarely produces any fruit under natural condition In order to understand the causes of failure of seed set in this ...

The effect of temperature on pollen germination and pollen tube growth of sour cherry cultivars [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2014
The study was carried out to determine the effect of three different temperatures (5, 15 and 25°C) on in vitro pollen germination and pollen tube growth of five sour cherry cultivars: ‘Heimanns Konservenweichsel’, ‘Kelleriis 14’, ‘Oblačinska ...

AtFH5-labeled secretory vesicles-dependent calcium oscillation drives exocytosis and stepwise bulge during pollen germination

open access: yesCell Reports, 2023
Summary: Pollen germination is an essential step for delivering sperm cells to the embryo sac for double fertilization in flowering plants. The cytosolic Ca2+ concentration ([Ca2+]cyt) and vesicle dynamics are critical for pollen germination, but their ...

<i>In vitro</i> Pollen Grain Germination and Tube Growth of Ten Iranian Jujube (<i>Ziziphus jujuba</i>) Cultivars

open access: yesNotulae Scientia Biologicae, 2014
Jujube (Ziziphus jujuba) is a species particularly prone to erratic fruit set. Several causes such as pollen germination and tube growth involve in this behaviour.

The effect of temperature on pollen germination and pollen tube growth of pear cultivars [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2016
The effect of three different temperatures (8, 16 and 24°C) on pollen germination and length of pollen tube in vitro was investigated in four pear cultivars (‘Butirra Precoce Morettini’, ‘Williams’, ‘Conference’ and ‘Abate Fetel’).

Boron deficiency responses in maize (Zea mays L.) roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

GORI encoding the WD40 domain protein is required for pollen tube germination and elongation in rice.

open access: yesThe Plant Journal, 2020
Successful sperm cell delivery to the embryo sac is mediated by pollen tube growth in higher plants. The molecular mechanisms underlying pollen germination and tube growth in crop plants remain highly unclear, although these mechanisms are crucial to ...

Pollen viability and in vitro germination of six pistachio (Pistacia vera L.) cultivars grown in northern Jordan

open access: yesAdvances in Horticultural Science, 2019
This study was conducted on six pistachio cultivars (Lazaourdi, Nab-El Jamal, Boundiki, Batouri, Marawhi and Aschouri) to investigate the percentage of pollen viability and in vitro pollen germination under stored and non-stored (fresh) conditions.

Glutathione synthesis is essential for pollen germination in vitro

open access: yesBMC Plant Biology, 2011
Background The antioxidant glutathione fulfills many important roles during plant development, growth and defense in the sporophyte, however the role of this important molecule in the gametophyte generation is largely unclear. Bioinformatic data indicate
