PIN3的分布【4】 与PIN3相似， PIN4-GFP 在顶端弯钩也是非对称分布，在弯钩凸面比凹面分布多。 在同一细胞中，PIN4-GFP在基部一侧的细胞膜和表皮一侧的细胞膜分布较多。 另 …
Antigravitropic PIN polarization maintains non-vertical growth in ...
2023年9月4日 · In contrast, PIN4:GFP and PIN7:GFP are undetectable in emerging lateral roots (stages I and II), with PIN7 expression in the columella becoming apparent in stage III and …
The PIN auxin efflux facilitator network controls growth and
2005年1月6日 · PIN4 is detected around the quiescent centre and cells surrounding it, and localizes basally in provascular cells 8 (Fig. 1k). PIN7 resides at lateral and basal membranes …
Functional redundancy of PIN proteins is accompanied by auxin …
2005年10月15日 · To address the post-transcriptional effects of auxin on the abundance of PIN proteins, we utilized GUS and GFP translation fusions with PIN1, PIN2, PIN4 and PIN7.
Differential Auxin-Transporting Activities of PIN-FORMED …
2010年5月3日 · Root-hair-specific overexpression of the long-looped PINs (PIN1–PIN4 and PIN7; ProE7: PIN-GFP [PINox]) greatly inhibited root hair growth (Fig. 1, B and C; Supplemental Fig. …
Osmotic stress represses root growth by modulating the …
2021年8月22日 · In transgenic plants expressing PIN-GFP fusion constructs, PIN1 and PIN4 transcript abundance decreased under osmotic stress, with associated reductions in PIN1 …
Auxin efflux controls orderly nucellar degeneration and expansion …
2020年12月18日 · We found that distal maternal auxin is transported into the nucellus by the auxin efflux carrier PIN1, and that auxin is further distributed in the nucellus surrounding the …
Flavonol‐mediated stabilization of PIN efflux complexes …
2020年11月13日 · In this report, we investigate the relationship between NPA and the PIN proteins, showing that (i) NPA directly inhibits PIN1‐mediated cellular auxin efflux, (ii) the …
AtPIN4 Mediates Sink-Driven Auxin Gradients and Root Patterning …
2002年3月8日 · We propose a role for AtPIN4 in generating a sink for auxin below the quiescent center of the root meristem that is essential for auxin distribution and patterning.
