Developmental transcriptome profiling uncovered carbon signaling genes associated with almond fruit drop

Abstract Almond is one of the most featured nut crops owing to its high nutritional value. However, due to three different waves of flower and fruitlet drop, fruit drop is a major concern for growers. In this study, we carried out a time-course transcriptome analysis to investigate gene expression d...
