Functional analyses of cytokinin (CK)-deficient plants provide direct evidence that CKs negatively regulate plant response to drought and salt stresses. CK-deficient plants exhibited a strong stress-tolerant phenotype associated with abscisic acid (ABA) hypersensitivity. This study suggests that mutual regulation mechanisms between CK and ABA affect the plant’s adaptation to stressors and plant growth and development.

Functional analyses of cytokinin (CK)-deficient plants provide direct evidence that CKs negatively regulate plant response to drought and salt stresses. CK-deficient plants exhibited a strong stress-tolerant phenotype associated with abscisic acid (ABA) hypersensitivity. This study suggests that mutual regulation mechanisms between CK and ABA affect the plant’s adaptation to stressors and plant growth and development.

Functional analyses of cytokinin (CK)-deficient plants provide direct evidence that CKs negatively regulate plant response to drought and salt stresses. CK-deficient plants exhibited a strong stress-tolerant phenotype associated with abscisic acid (ABA) hypersensitivity. This study suggests that mutual regulation mechanisms between CK and ABA affect the plant’s adaptation to stressors and plant growth and development.

The maize gene opaque5 encodes a monogalactosyldiacylglycerol synthase. Mutant analysis reveals that galactolipids with five double bonds are needed for thylakoid membrane function and cannot be substituted by the prevalent species with six double bonds. Galactolipid reduction results in altered starch granules, indicating a connection between amyloplast membranes and starch biosynthesis.
