Germplasm Phenotype:

• xpt-1/tpt-1  — Severely retarded in size, high chlorophyll fluorescence phenotype, impaired photosynthetic electron transport rates. Export of triose phosphates from the chloroplasts is completely blocked. Accelerated day-time starch turnover, accumulations of pentose phosphates, maltose and organic acids, drop in Gly. Components of the photosynthetic electron transport chain less abundant in thylakoids.
• xpt-1/tpt-2  — Severely retarded in size, high chlorophyll fluorescence phenotype, impaired photosynthetic electron transport rates. Export of triose phosphates from the chloroplasts is completely blocked. Accelerated day-time starch turnover, accumulations of pentose phosphates, maltose and organic acids, drop in Gly. Components of the photosynthetic electron transport chain less abundant in thylakoids.
