Exocytosis-coordinated mechanisms for tip growth underlie pollen tube growth guidance
Nature Communications, 2017 Many tip-growing cells are capable of responding to guidance cues, during which cells precisely steer their growth toward the source of guidance signals.

Regulation of Pollen Tube Growth by Transglutaminase [PDF]
Plants, 2013 In pollen tubes, cytoskeleton proteins are involved in many aspects of pollen germination and growth, from the transport of sperm cells to the asymmetrical distribution of organelles to the deposition of cell wall material. These activities are based on the dynamics of the cytoskeleton.

Interaction Between Actin and Microtubules During Plant Development
Cytoskeleton, EarlyView.ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

Ovary Signals for Pollen Tube Guidance in Chalazogamous Mangifera indica L.
Frontiers in Plant Science, 2021 Most flowering plants show porogamy in which the pollen tubes reach the egg apparatus through the micropyle. However, several species show chalazogamy, an unusual pollen tube growth, in which the pollen tubes reach the embryo sac through the chalaza ...

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
Cytoskeleton, EarlyView.ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Acta Agrobotanica, 2015 During four years (1971-1974), five sour cherry cultivars were examined for the pollen viability, germination and pollen tube growth. Pollen which was taken from the earliest and the last blooming stages had the smaller viability, germination and the ...

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

A Novel Pollen-Pistil Interaction Conferring High-Temperature Tolerance during Reproduction via CLE45 Signaling [PDF]
, 2013 SummaryFlowering plants in the reproductive stage are particularly vulnerable to ambient temperature fluctuations [1–6]. Nevertheless, they maintain seed production under certain levels of exposure to temperature change.

Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Pollination, Fertilization, and Embryo Development in Southern China Fresh-eating Jujube
HortScience, 2020 To explore the reasons for seed abortion in southern China fresh-eating jujube, improve its reproductive biology, and provide a theoretical basis for the crossbreeding of jujube, we carried out self-pollination and cross-pollination experiments with ...
