HvSWEET11b transports both sugar and cytokinin in developing barley grains, essential for grain growth and yield. The dual function of HvSWEET11b is crucial for plant adaptation to changing environments.
A fungus, Moniliophthora perniciosa, causes witches' broom disease in cocoa trees by releasing cytokinin, altering plant hormone balance. The fungus then consumes lignin produced by the tree's vascular tissue after its death.
Researchers discovered regulation of cytokinin is central to balancing nitrogen acquisition. Legumes restrict nodules when nitrogen is abundant, acquiring instead from the soil.
Scientists have discovered the mechanism by which plant hormone cytokinin regulates stem cell division, controlling cell proliferation and mitosis. The study reveals that cytokinin activates the transcription factor MYB3R4, promoting its nuclear localization and activating key cell cycle genes.
A team of scientists has found a way for genes to self-repress, reducing potential side effects and allowing novel forms to evolve. This discovery was made using the hairy bittercress plant as a model system.
The researchers found that a hormone called cytokinin coordinates the number of stomata in plants, which can be increased or decreased through gene editing technology. This discovery suggests opportunities for engineering plants to adapt to climate change and fine-tunes the process by which plants regulate stomatal development.
Cytokinins have been found to play a vital role in the communication mechanisms of bacteria, plants and animals, regulating growth, development and disease resistance. The research has also uncovered new details on how cytokinins evolve and activate enzymes, challenging previous assumptions.
A sophisticated mechanism allows plant roots to quickly respond to changes in soil conditions via the interactions of two antagonistic hormones, auxin and cytokinin. Cells sense relative changes in auxin levels to determine their location within the root and trigger a switch from cell division to elongation.
Scientists have identified how cytokinin activates genes to regulate plant growth, allowing for stem cell establishment in grains like rice and corn. The study reveals the mechanism of type-B ARRs in regulating cytokinin response and growing shoots in tissue culture.
Researchers have identified a novel mechanism by which beneficial microbes produce plant hormones to control plant diseases. The study found that bacteria can efficiently control pathogen infections in model plants by producing cytokinin, allowing the plants to maintain tissue integrity and biomass yield.
Researchers discovered cytokinin patterning cannot happen via diffusion alone, with unexpected physical constraints on pattern formation. Computational simulations identified limits on cytokinin movement and patterning, revealing a need to solve the puzzle of how patterns are created.

Researchers discovered a new route for legume plants to communicate with their symbiotic bacteria. The study found that cytokinins, signaling molecules, are transmitted from leaves to roots to control the number of bacterial-holding nodules. This innovation allows legumes to balance energy production and nodule development.
Cytokinins, produced in legume leaves, play a crucial role in regulating root nodule numbers by signaling from the roots to the leaves. This discovery sheds new light on the symbiotic balance between rhizobia and legumes.
A new study identifies a protein essential for relocating cytokinins from roots to shoots, regulating plant growth and development. The research has implications for increasing biomass yield and stress tolerance of plants grown for biofuels or agriculture.
A new regulator for plant hormone signaling, the KISS ME DEADLY family of proteins (KMDs), has been identified by Dartmouth researchers. This discovery may lead to improved agricultural productivity and increased crop yields.

The modified plants also exhibit improved growth characteristics, such as increased branching and leaf density. This breakthrough is great news for gardeners who want to enjoy their plants for longer periods.
A recent study published in Nature found that auxin and cytokinin, two previously thought-to-be antagonistic plant growth hormones, actually cooperate to regulate plant growth. The international team of researchers discovered that auxin boosts the effect of cytokinin by suppressing genes that limit its activity.
