CDKN1A and hyperinsulinemic hypoglycemia, familial, 4: As an example, we found a series of induced genes that are associated with nutrient deficiency responses in Arabidopsis, including the sulfate-deficiency induced gene SDI1 (At5g48850) and the response to low sulfur gene LSU1 (At3g49580), as well as the phosphate deficiency-associated SPX domain genes SPX1 (At5g20150) and SPX3 (At2g45130), the PHO1 sulfate transporter homolog gene PHO1-H10 (At1g69480), and the phosphate-starvation induced inositol-3-phosphate synthase 2 gene IPS2 (At2g22240).
