RNA-seq of Ananas comosus pulp tissues during internal browning development
Internal browning (IB) is a major postharvest disorder in pineapple that causes substantial economic losses. This project aims to identify key genes and regulatory pathways governing IB development through comparative transcriptomic analysis of pineapple pulp tissues at the onset of browning. RNA-seq libraries were constructed from three tissue types: browning pulp (BP) and adjacent non-browning pulp (AP) from IB-affected fruits, and healthy control pulp (CK) from fruits without IB symptoms. Each group contains three biological replicates, totaling nine samples sequenced on the Illumina platform with paired-end reads.
