Arabidopsis Sar1 isoforms play redundant roles in female gametophytic development
Key message Functional loss of Arabidopsis Sar1b with that of either Sar1a or Sar1c inhibits mitosis of functional megaspores, leading to defective embryo sac formation and reduced fertility. Abstract Vesicular trafficking among diverse endomembrane compartments is critical for eukaryotic cells. Ant...

520 | |a Key message Functional loss of Arabidopsis Sar1b with that of either Sar1a or Sar1c inhibits mitosis of functional megaspores, leading to defective embryo sac formation and reduced fertility. Abstract Vesicular trafficking among diverse endomembrane compartments is critical for eukaryotic cells. Anterograde trafficking from endoplasmic reticulum (ER) to the Golgi apparatus is mediated by coat protein complex II (COPII) vesicles. Among five cytosolic components of COPII, secretion-associated Ras-related GTPase 1 (Sar1) mediates the assembly and disassembly of the COPII coat. Five genes in Arabidopsis encode Sar1 isoforms, whose different cargo specificities and redundancy were both reported. We show here that Arabidopsis Sar1a, Sar1b, and Sar1c mediate the development of female gametophytes (FGs), in which Sar1b plays a major role, whereas Sar1a and Sar1c play a minor role. We determined that female transmission of sar1a;sar1b or sar1c;sar1b was significantly reduced due to defective mitosis of functional megaspores. Half of ovules in sar1a;sar1b/+ or sar1c;sar1b/+ plants failed to attract pollen tubes, leading to fertilization failure. The homozygous sar1a;sar1b or sar1c;sar1b double mutant was obtained by introducing either UBQ10:GFP-Sar1b or UBQ10:GFP-Sar1c, supporting their redundant function in FG development. | ||

Abstract Vesicular trafficking among diverse endomembrane compartments is critical for eukaryotic cells. Anterograde trafficking from endoplasmic reticulum (ER) to the Golgi apparatus is mediated by coat protein complex II (COPII) vesicles. Among five cytosolic components of COPII, secretion-associated Ras-related GTPase 1 (Sar1) mediates the assembly and disassembly of the COPII coat. Five genes in Arabidopsis encode Sar1 isoforms, whose different cargo specificities and redundancy were both reported. We show here that Arabidopsis Sar1a, Sar1b, and Sar1c mediate the development of female gametophytes (FGs), in which Sar1b plays a major role, whereas Sar1a and Sar1c play a minor role. We determined that female transmission of sar1a;sar1b or sar1c;sar1b was significantly reduced due to defective mitosis of functional megaspores. Half of ovules in sar1a;sar1b/+ or sar1c;sar1b/+ plants failed to attract pollen tubes, leading to fertilization failure. The homozygous sar1a;sar1b or sar1c;sar1b double mutant was obtained by introducing either UBQ10:GFP-Sar1b or UBQ10:GFP-Sar1c, supporting their redundant function in FG development.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">COPII</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Embryo sac</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Female gametophyte</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fertility</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mitosis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Shan-Wei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Jin-Li</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao, Hui-Min</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Sha</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Yan</subfield><subfield code="0">(orcid)0000-0002-3501-5857</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Sexual plant reproduction</subfield><subfield code="d">Berlin : Springer, 1988</subfield><subfield code="g">36(2023), 4 vom: 03.

Key message Functional loss of Arabidopsis Sar1b with that of either Sar1a or Sar1c inhibits mitosis of functional megaspores, leading to defective embryo sac formation and reduced fertility. Abstract Vesicular trafficking among diverse endomembrane compartments is critical for eukaryotic cells. Anterograde trafficking from endoplasmic reticulum (ER) to the Golgi apparatus is mediated by coat protein complex II (COPII) vesicles. Among five cytosolic components of COPII, secretion-associated Ras-related GTPase 1 (Sar1) mediates the assembly and disassembly of the COPII coat. Five genes in Arabidopsis encode Sar1 isoforms, whose different cargo specificities and redundancy were both reported. We show here that Arabidopsis Sar1a, Sar1b, and Sar1c mediate the development of female gametophytes (FGs), in which Sar1b plays a major role, whereas Sar1a and Sar1c play a minor role. We determined that female transmission of sar1a;sar1b or sar1c;sar1b was significantly reduced due to defective mitosis of functional megaspores. Half of ovules in sar1a;sar1b/+ or sar1c;sar1b/+ plants failed to attract pollen tubes, leading to fertilization failure. The homozygous sar1a;sar1b or sar1c;sar1b double mutant was obtained by introducing either UBQ10:GFP-Sar1b or UBQ10:GFP-Sar1c, supporting their redundant function in FG development. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2023 |

Abstract Vesicular trafficking among diverse endomembrane compartments is critical for eukaryotic cells. Anterograde trafficking from endoplasmic reticulum (ER) to the Golgi apparatus is mediated by coat protein complex II (COPII) vesicles. Among five cytosolic components of COPII, secretion-associated Ras-related GTPase 1 (Sar1) mediates the assembly and disassembly of the COPII coat. Five genes in Arabidopsis encode Sar1 isoforms, whose different cargo specificities and redundancy were both reported. We show here that Arabidopsis Sar1a, Sar1b, and Sar1c mediate the development of female gametophytes (FGs), in which Sar1b plays a major role, whereas Sar1a and Sar1c play a minor role. We determined that female transmission of sar1a;sar1b or sar1c;sar1b was significantly reduced due to defective mitosis of functional megaspores. Half of ovules in sar1a;sar1b/+ or sar1c;sar1b/+ plants failed to attract pollen tubes, leading to fertilization failure. The homozygous sar1a;sar1b or sar1c;sar1b double mutant was obtained by introducing either UBQ10:GFP-Sar1b or UBQ10:GFP-Sar1c, supporting their redundant function in FG development.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">COPII</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Embryo sac</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Female gametophyte</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fertility</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mitosis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Shan-Wei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Jin-Li</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao, Hui-Min</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Sha</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Yan</subfield><subfield code="0">(orcid)0000-0002-3501-5857</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Sexual plant reproduction</subfield><subfield code="d">Berlin : Springer, 1988</subfield><subfield code="g">36(2023), 4 vom: 03.
