Meena et al. (2021) found that the relative expression of some P stress induced (PSI) genes in mungbean accession IC333090 (P-deficiency and drought stress tolerant accession) were significantly higher than that of sensitive accession IC488526, such as SPX1, sulfolipid sulfoquinovosyl diacylglycerol 1 (SQD1), Phosphate1 (PHO1), and purple acid phosphatase 1 (PAP1) [65]. The gene discussed is SPX; the disease is hyperinsulinemic hypoglycemia, familial, 4.
