Poly(A) polymerase 1 contributes to competence acquisition of pollen …
2023年2月22日 · Here we test this notion by studying the function of PAPS1 in pollen-tube growth and guidance. Pollen tubes growing through female tissue acquire the competence to find …
Growth assay of individual pollen tubes arrayed by microchannel device
2014年4月25日 · Here, we present a new method to assay pollen tube growth using poly-dimethylsiloxane microchannel device to isolate individual pollen tubes. The growth of the …
Pollen-expressed RLCKs control pollen tube burst - Cell Press
This study reports the identification of three pollen tube–expressed RLCKs, DEB1/2/3, that control pollen tube burst through interacting with the Ca2+ pump ACA9 on the plasma membrane to …
Bioenergetics of pollen tube growth in - Nature
2022年12月19日 · By monitoring dynamic changes in ATP and NADPH concentrations and the NADH/NAD + ratio at the subcellular level in Arabidopsis (Arabidopsis thaliana) pollen tubes, …
Plasma membrane H+-ATPases sustain pollen tube growth and ... - Nature
2020年5月14日 · Pollen tubes are highly polarized tip-growing cells that depend on cytosolic pH gradients for signaling and growth. Autoinhibited plasma membrane proton (H +) ATPases …
Pollen tube growth from multiple pollinator visits more accurately ...
2020年10月12日 · We found that pollen deposition from a single pollinator visit seldom resulted in the growth of pollen tubes capable of eliciting ovule fertilisation and never resulted in fruit or …
The poly(A) polymerase PAPS1 mediates pollen maturation by …
Here, we found the new and significant role of poly (A) polymerase PAPS1 in mediating pollen maturation by activating a germline-specific differentiation program through downregulating …
Mechanics and hydraulics of pollen tube growth
2021年9月7日 · For pollen tubes, tip growth is how the male gametophyte reaches the ovule nestled deep into the pistil of the flower to achieve fertilisation (Williams et al., 2016). Tip …
'Roly-poly toy' motion during pollen exudation promotes rapid pollen …
2024年5月23日 · Here we show the exact dynamics of captured pollen grains during pollen exudation in rice. We found that the exudates originated from the grains ran down toward the …
Deep imaging reveals dynamics and signaling in one-to-one pollen tube …
2024年5月21日 · Here, we develop a two-photon live imaging method to directly observe pollen tube guidance in the pistil of Arabidopsis thaliana, clarifying signaling and cellular behaviors in …
