Cold stress negatively affects maize (Zea mays L.) growth, development and yield. Metabolic adjustments contribute to the adaptation of maize under cold stress. We show here that the transcription factor INDUCER OF CBF EXPRESSION 1 (ZmICE1) plays a prominent role in reprogramming amino a...
Heterosis, or hybrid vigor, refers to the phenomenon where F1 hybrids outperform their parental inbred lines. Despite more than a century of intensive research across various species, the genetic basis and environmental regulation of heterosis, particularly belowground, remain poorly understood. ...
Seed aging leads to reduced germination rates and vigor, particularly under stress conditions. We subjected aged maize seeds to 40 seconds of ultrasonic treatment, which enhanced their vigor and tolerance to combined stress. The ultrasonic treatment increased more cracks and holes in the seed coa...
Aromatic amino acids are essential precursors for numerous plant metabolites, with phenylalanine (Phe) forming the basis of the phenylpropanoid pathway. Here, we reveal a critical mechanism for Phe biosynthesis in maize, demonstrating that all seven arogenate dehydratases (ADTs) are specifically ...
