Germplasm Phenotype:

• SALK_110027  — Cotyledons of seven day old plants are paler than those of Col-0, with a 35-40% and 50% reduction in chlorophyll a and chlorophyll b contents compared with Col-0. Induction of expression of light responsive genes RBCS-1A and CAB2 during germination is seriously impaired.
• SALK_110029  — Cotyledons of seven day old plants are paler than those of Col-0, with a 35-40% and 50% reduction in chlorophyll a and chlorophyll b contents compared with Col-0. Induction of expression of light responsive genes RBCS-1A and CAB2 during germination is seriously impaired.
• haf2-1  — Cotyledons of seven day old plants are paler than those of Ws, with a 35-40% and 50% reduction in chlorophyll a and chlorophyll b contents compared with Ws. Newly produced youg leaves and shoots are yellowish. During expansion, the leaves become gradually greener from the base to the distal end. Induction of expression of light responsive genes RBCS-1A and CAB2 during germination is seriously impaired.
