Inconsistent integration and poor regeneration rates limit the ability to modify specific plant species. Overcoming these barriers allows for broader germplasm engineering and predictable transgene expression.

Deficiency in flavonoid biosynthesis leads to male sterility through failed pollen development and germination. Restoring this specific metabolic pathway ensures reproductive viability and seed set.

Endogenous plant promoters often lack the precision required for specific timing or tissue-specific activation. Precise control prevents off-target metabolic drain and unintended phenotypic changes.
