Cytokinins (CKs) are known to regulate the biogenesis of chloroplasts under changing environmental conditions and at different stages of plant ontogenesis. However, the underlying mechanisms are still poorly understood. Apparently, the mechanisms can be duplicated in several ways, including the influence of nuclear genes that determine the expression of plastome through the two-component CK regulatory circuit.

- Heat shock significantly impacts plant growth by altering chloroplast gene expression in Arabidopsis thaliana, leading to an initial decrease in many transcript levels followed by a rebound for some genes.
- During heat stress, certain genes, particularly those associated with photosystems, exhibit complex transcript dynamics, including temporary increases and eventual reductions, highlighting the stress response mechanisms.
- The study suggests that heat stress affects transcript levels via a combination of chloroplast and nuclear gene expression changes, with specific mutants showing impaired responses due to genetics.

Cytokinin membrane receptors of the Arabidopsis thaliana AHK2 and AHK3 play opposite roles in the expression of plastid genes and genes for the plastid transcriptional machinery during leaf senescence Loss-of-function mutants of Arabidopsis thaliana were used to study the role of cytokinin receptors in the expression of chloroplast genes during leaf senescence. Accumulation of transcripts of several plastid-encoded genes is dependent on the АНК2/АНК3 receptor combination. АНК2 is particularly important at the final stage of plant development and, unlike АНК3, a positive regulator of leaf senescence.
