Arabidopsis	At4g04970	Required the formation of the callose wall separating the tetraspores (interstitial wall), but not for the callose wall surrounding the pollen mother cells (peripheral wall).	Two callose synthases, GSL1 and GSL5, play an essential and redundant role in plant and pollen development and in fertility.; 2005; DOI: 10.1007/s11103-005-4526-7; PMID: 16021399; https://pubmed.ncbi.nlm.nih.gov/16021399/
Arabidopsis	At4g03550	Involved in sporophytic and gametophytic development.	An Arabidopsis callose synthase.; 2002; DOI: 10.1023/a:1015558231400; PMID: 12081364; https://pubmed.ncbi.nlm.nih.gov/12081364/ | An Arabidopsis Callose Synthase, GSL5, Is Required for Wound and Papillary Callose Formation.; 2003; DOI: 10.1105/tpc.016097; PMID: 14555698; https://pubmed.ncbi.nlm.nih.gov/14555698/ | Two callose synthases, GSL1 and GSL5, play an essential and redundant role in plant and pollen development and in fertility.; 2005; DOI: 10.1007/s11103-005-4526-7; PMID: 16021399; https://pubmed.ncbi.nlm.nih.gov/16021399/
Arabidopsis	At2g13680	Required for the formation of the callose wall separating the tetraspores (interstitial wall) and surrounding the pollen mother cells (peripheral wall).	Callose synthase (CalS5) is required for exine formation during microgametogenesis and for pollen viability in Arabidopsis.; 2005; DOI: 10.1111/j.1365-313x.2005.02379.x; PMID: 15842618; https://pubmed.ncbi.nlm.nih.gov/15842618/ | Callose (beta-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth.; 2005; DOI: 10.1186/1471-2229-5-22; PMID: 16212660; https://pubmed.ncbi.nlm.nih.gov/16212660/
Arabidopsis	At2g36850	Involved in sporophytic and gametophytic development.	Dual function of Arabidopsis glucan synthase-like genes GSL8 and GSL10 in male gametophyte development and plant growth.; 2008; DOI: 10.1111/j.1365-313x.2008.03462.x; PMID: 18315544; https://pubmed.ncbi.nlm.nih.gov/18315544/ | Dysregulation of cell-to-cell connectivity and stomatal patterning by loss-of-function mutation in Arabidopsis chorus (glucan synthase-like 8).; 2010; DOI: 10.1242/dev.049197; PMID: 20430748; https://pubmed.ncbi.nlm.nih.gov/20430748/
