Phenotypes of sCAX1- and CAX4-expressing tomato plants. A, Growth of TVC1-1 vector control (left) and the sCAX1-expressing TCX1-2 plant (right) after 3 weeks in soil. B, Growth of vector control (left) and sCAX1-expressing TCX1-2 plant (right) after 5 months in soil. C, Growth of vector control (left) and CAX4-expressing TCX4-16 plant (right) after 4 months in soil. D, sCAX1-expressing TCX1-2 tomato grown in soil for 2 months without application of exogenous Ca²⁺ (left) and with the addition of Ca²⁺ (right). E, Root structure of vector control (left) and sCAX1-expressing TCX1-2 plant (right). F, Leaf phenotype of vector control (left) and sCAX1-expressing TCX1-4 plant (right).
