We could similarly use mutate_if() to mutate columns that satisfy specified logical conditions. In the example below, we mutate all columns that have at least one missing value by replacing NA with "missing". av_survey_sample %>% # only mutate columns with at least one NA # replace each...
(GMS) genes. To investigate the role of multiple homologous genes in anther and pollen developments of maize, we established the CRISPR/Cas9-based gene editing method to simultaneously mutate the homologs in several putative GMS gene families. By using the integrated strategies of multi-gene ...
