The canonical IAA14– ARF7/19 signaling module and its downstream targets, including LATERAL ORGAN BOUNDARIES DOMAIN (LBD) transcription factors and WRKY23, are indispensable for callus formation and the establishment of cellular pluripotency.
Abstract
Plant cells possess remarkable developmental plasticity and can regain their proliferative capacity through cellular reprogramming to form pluripotent cell masses known as callus, which serves as the foundation for plant regeneration and tissue culture. Induction of callus formation begins with explants on auxin-rich callus-inducing medium (CIM), a process tightly controlled by auxin signaling. The canonical IAA14– ARF7/19 signaling module and its downstream targets, including LATERAL ORGAN BOUNDARIES DOMAIN (LBD) transcription factors and WRKY23, are indispensable for callus formation and the establishment of cellular pluripotency (Xu et al. 2023). Lipids are fundamental components of plant membranes that maintain membrane integrity, dynamics, and energy storage.
Plants have remarkable capacity to reconstruct entire organ systems from tissue explants. In Arabidopsis two-step tissue culture system, pluripotency regulators are specifically expressed in the middle-cell layer of the stratified callus tissue. However, regulatory mechanisms underlying the radial patterning of callus...

Hormone-free callus induction in kiwifruit is associated with coordinated ROS accumulation, endogenous hormone reprogramming, and transcriptional network changes that may contribute to embryogenic-like callus divergence.

Gall induction by hymenopteran gall wasps is one of the most sophisticated forms of plant-insect interaction, in which insects manipulate plant development to produce specialized, nutrient-rich structures that support their growth and reproduction. Despite substantial advances, the biochemical and molecular mechanisms...

Recent advances in plant nutrient signalling during development are reviewed, focussing on how carbon and nitrogen signals inform shoot apical meristem activity and the emerging idea that meristem regulators may reciprocally influence nutrient signalling pathways and metabolism is considered.

Throughout their life cycle, plants are capable of forming organs by differentiating from special tissues called meristems. The shoot apical meristem (SAM) produces all above ground organs, such as leaves, axillary shoots, and flowers, through the continuous regeneration of stem cells. A delicate balance exists between...

Plants exhibit diverse regeneration strategies to heal wounds, regrow organs, and clonally propagate. These regeneration strategies depend on inductive cues such as wounding, stress or hormones initiating cell division and cell differentiation. However, wounding activates both regeneration and defence responses, and it...
