Genome-Wide Identification and Expression Analysis of PaNRT Gene Family Under Various Nitrogen Conditions in Avocado (Persea americana Mill.)

Description

Yuan Tian, Ruiyuan Jiang, and Jian Qin catalogued the nitrate transporter gene family across the avocado genome. Avocado trees demand heavy nitrogen feeding, and these transporters control nitrate uptake and use. No systematic inventory existed for the species. Bioinformatics found sixty-one family members scattered over twelve chromosomes. Their promoter regions carry many switches responding to hormones and stress. The team also grew seedlings under five nitrogen doses.

One middle dose produced the healthiest nitrogen-processing enzyme activity and leaf nitrogen content. Low and normal nitrogen supplies were then chosen for gene expression sequencing. The resulting expression atlas shows which transporters react to scarcity or plenty. Breeders and growers can use the twenty twenty-four map to match fertilizer regimes to the tree's own uptake machinery.
