Project description:This study provides nAnT-iCAGE-seq data from cassava (Manihot esculenta) exposed to 42°C (heat), 4°C (cold), and control conditions. The dataset includes raw sequencing reads, processed transcription start site (TSS) profiles, and annotations for alternative promoter genes (APGs) and differentially expressed genes (DEGs). Data were generated using Illumina 2000/2500 platforms.
