Genomic and Functional Analysis of the ALOG Gene Family in Dioscorea alata

Plants
The ALOG (Arabidopsis LIGHT-DEPENDENT SHORT HYPOCOTYLS 1 (LSH1) and Oryza G1) family play crucial regulatory roles in plant growth and development, spanning both vegetative and reproductive growth. This study presents a comprehensive genomic and functional analysis of the ALOG family in greater yam (Dioscorea alata). Ten non-redundant DaALOG genes were
