Transitions from alkaline spots to regular bands during pH pattern formation at the plasmalemma of Chara cells

Abstract A scanning pH-microprobe was used to study pH patterns near the surface of Chara corallina cells at various light intensities and during light-induced transitions from homogeneous pH distribution to alternating pH bands. In the irradiance (PAR) range 4–400 μmol quanta $ m^{−2} $ $ s^{−1} $,...

520			\|a Abstract A scanning pH-microprobe was used to study pH patterns near the surface of Chara corallina cells at various light intensities and during light-induced transitions from homogeneous pH distribution to alternating pH bands. In the irradiance (PAR) range 4–400 μmol quanta $ m^{−2} $ $ s^{−1} $, the sustained pH profiles consisted of alternating acid and alkaline bands with a characteristic length of 7–10 mm and pH shifts as large as 2–3 units. At lower irradiances, the number of alkaline bands decreased while the amplitude of remaining peaks stayed high. On cyclic changes in light intensity, a hysteresis of pH banding was observed: the pH bands tolerated low irradiance in weakening light, but higher irradiance was required for their emergence after dark adaptation of the cell. The pH profiles measured for different paths of electrode scanning suggest that the pH pattern at low light level represents patches coexisting with bands. The exposure of the cell to high-intensity light led to formation of radially symmetrical bands. Transformations of the pH pattern induced by lowering the light intensity were similar to those induced by transcellular electric current (1.5–3 μA). The data suggest that band formation at the plasmalemma of Chara cells proceeds through the initial appearance of multiple patches with a localized $ H^{+} $-transporting activity and subsequent spot rearrangements (fusion, deletions, widening), leading to establishment of alternating bands.

In the irradiance (PAR) range 4–400 μmol quanta $ m^{−2} $ $ s^{−1} $, the sustained pH profiles consisted of alternating acid and alkaline bands with a characteristic length of 7–10 mm and pH shifts as large as 2–3 units. At lower irradiances, the number of alkaline bands decreased while the amplitude of remaining peaks stayed high. On cyclic changes in light intensity, a hysteresis of pH banding was observed: the pH bands tolerated low irradiance in weakening light, but higher irradiance was required for their emergence after dark adaptation of the cell. The pH profiles measured for different paths of electrode scanning suggest that the pH pattern at low light level represents patches coexisting with bands. The exposure of the cell to high-intensity light led to formation of radially symmetrical bands. Transformations of the pH pattern induced by lowering the light intensity were similar to those induced by transcellular electric current (1.5–3 μA). The data suggest that band formation at the plasmalemma of Chara cells proceeds through the initial appearance of multiple patches with a localized $ H^{+} $-transporting activity and subsequent spot rearrangements (fusion, deletions, widening), leading to establishment of alternating bands.

In the irradiance (PAR) range 4–400 μmol quanta $ m^{−2} $ $ s^{−1} $, the sustained pH profiles consisted of alternating acid and alkaline bands with a characteristic length of 7–10 mm and pH shifts as large as 2–3 units. At lower irradiances, the number of alkaline bands decreased while the amplitude of remaining peaks stayed high. On cyclic changes in light intensity, a hysteresis of pH banding was observed: the pH bands tolerated low irradiance in weakening light, but higher irradiance was required for their emergence after dark adaptation of the cell. The pH profiles measured for different paths of electrode scanning suggest that the pH pattern at low light level represents patches coexisting with bands. The exposure of the cell to high-intensity light led to formation of radially symmetrical bands. Transformations of the pH pattern induced by lowering the light intensity were similar to those induced by transcellular electric current (1.5–3 μA). The data suggest that band formation at the plasmalemma of Chara cells proceeds through the initial appearance of multiple patches with a localized $ H^{+} $-transporting activity and subsequent spot rearrangements (fusion, deletions, widening), leading to establishment of alternating bands.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alkaline and acid bands</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hysteresis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">pH microelectrode</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Photosynthesis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zykov, S.

title_auth	Transitions from alkaline spots to regular bands during pH pattern formation at the plasmalemma of Chara cells
abstract	Abstract A scanning pH-microprobe was used to study pH patterns near the surface of Chara corallina cells at various light intensities and during light-induced transitions from homogeneous pH distribution to alternating pH bands. In the irradiance (PAR) range 4–400 μmol quanta $ m^{−2} $ $ s^{−1} $, the sustained pH profiles consisted of alternating acid and alkaline bands with a characteristic length of 7–10 mm and pH shifts as large as 2–3 units. At lower irradiances, the number of alkaline bands decreased while the amplitude of remaining peaks stayed high. On cyclic changes in light intensity, a hysteresis of pH banding was observed: the pH bands tolerated low irradiance in weakening light, but higher irradiance was required for their emergence after dark adaptation of the cell. The pH profiles measured for different paths of electrode scanning suggest that the pH pattern at low light level represents patches coexisting with bands. The exposure of the cell to high-intensity light led to formation of radially symmetrical bands. Transformations of the pH pattern induced by lowering the light intensity were similar to those induced by transcellular electric current (1.5–3 μA). The data suggest that band formation at the plasmalemma of Chara cells proceeds through the initial appearance of multiple patches with a localized $ H^{+} $-transporting activity and subsequent spot rearrangements (fusion, deletions, widening), leading to establishment of alternating bands. © EBSA 2003
