About this Research Topic
Shoot Apical Meristems (SAM) ensure the continuous production of new organs such as leaves, lateral shoots, inflorescences, and flowers throughout a plant's life. SAMs, originating during embryogenesis, contain undifferentiated, pluripotent cells forming a stem cell niche. Some descendants differentiate into new organs or tissues, while others maintain the niche's reservoir. Thus, SAMs balance between dividing cells to produce new organs and maintaining totipotent cells is crucial for the development of above-ground plant structures.
Recent decades have seen significant progress in understanding the regulatory networks maintaining SAMs. These networks include regulatory genes (e.g., Homeodomain Transcription Factors like WUSCHEL), signaling peptides and receptors (e.g., CLAVATA pathway), and key hormones (e.g., auxin and cytokinin).
Manipulating SAMs presents numerous biotechnological opportunities. Application of morphogenetic regulators (e.g., WUS and BABY BOOM genes) enhances plant transformation and regeneration efficiency, even in recalcitrant species or varieties (Boutilier et al., 2002; Lowe et al., 2016). Additionally, traits such as yield, flower and fruit number, and stress resistance are influenced by SAM and Floral Meristem activity (Fletcher, 2018). Understanding SAM mechanisms allows for better adjustment and modification of these traits.
This Research Topic aims to gather cutting-edge research on the innovative manipulation of the apical meristem for biotechnological improvements across plants, algae, and simpler organisms.

• Modulation of hormonal pathways for growth enhancement.
3. Genetic modification and genome editing:
• Use of CRISPR/Cas9 and other gene-editing technologies on the SAM .
• Transgenic approaches to modify growth and development pathways.
4. Novel plant tissue-culture techniques :
• In vitro meristem culturing techniques.
• Novel approaches to improve plant transformation and regeneration.
5. Adaptive growth:
