identification of thanatos, a semidominant mutant of Arabidopsis thaliana with impaired growth of seedlings due to a mutation in the catalytic domain of cellulose synthase 3, homozygous seedlings of than germinate and grow but do not survive, while heterozygous plants are dwarfed and display a radially swollen root phenotype, cellulose content is reduced by approximately one-fifth in heterozygous and by two-fifths in homozygous plants, overview. Gene dosage-dependent expression of the AtCesA3 mutant gene in wild-type Arabidopsis thaliana plants results in a than dominant-negative phenotype. The mutation alters the structure of the CESA3 catalytic domain
the naturally occuring irx3-1 and irx5-2 mutations are caused by premature stop codons that result in protein truncation of CESA7 and CESA4, respectively. In the naturally occuring irx3-1 background, interaction between CESA4 and CESA8 is greatly reduced, and the proteins fail to localize to the plasma membrane. Cellulose contents of mutant lines irx5 and irx1 plants recombinantly expressing CESA8 and CESA4, irx5-2:STREP-CESA4 and irx1-1:STREPCESA8, are much lower than wild-type and as such are not fully functional. Recombinant mutant irx3-1 plants expressing STREP-CESA7 and His/FLAGCESA7 in a dual tag system have wild-type cellulose content and xylem phenotypes, overview. irx3-1:STREP-CESA7-irx3-1:His/FLAG-CESA7 crossed plants phenotype, overview

recombinant expression of genes csr2 and csr4in antisense orientation in transgenic Solanum tuberosum lines csr21 and csr48, and as double transformants. Medium-level downregulation of the CesA2 mRNA is observed in the csr2 tubers, but phenotypes may more likely be the result of downregulation of other CesA genes by siRNAs and not the result of downregulation of CesA2, overview
