Juvenile Leaves or Adult Leaves: Determinants for Vegetative Phase Change in Flowering Plants

Abstract: Vegetative leaves in Arabidopsis are classified as either juvenile leaves or adult leaves based on their specific traits, such as leaf shape and the presence of abaxial trichomes. The timing of the juvenile-to-adult phase transition during vegetative development, called the vegetative phase change, is a critical decision for plants, as this transition is associated with crop yield, stress responses, and immune responses. Juvenile leaves are characterized by high levels of miR156/157, and adult leaves are chara… Show more

“…ABI3 interacts with ABI5 at the protein level, and it also acts upstream of ABI5 (Nakamura et al, 2001; Lopez‐Molina et al, 2002). ABI3 can directly bind to the promoters of miR156a , miR156c , and miR156d loci; ABI3 is therefore thought to link the ABA signaling pathway to regulate vegetative development (Manuela & Xu, 2020). However, the question of how ABI3 is involved in vegetative development remains unexplored.…”

“…The basic mechanisms of heterophylly at the molecular level have been elucidated in model plants, such as Arabidopsis thaliana ( Yang et al, 2013 ; Rubio-Somoza et al, 2014 ; Xu et al, 2019 ). Over the past decade, a key regulatory module consisting of miR156 and its targets, the SQUAMOSA PROMOTER BINDING PROTEIN-LIKE ( SPL ) genes, was shown to play important roles in diverse aspects of plant development, including phase transition, heterophylly, and heteroblasty ( Wu et al, 2009 ; Poethig, 2013 ; Manuela and Xu, 2020 ). Several studies have revealed the molecular mechanisms underlying heterophylly in non-model plants ( Nakayama et al, 2014 ; Sicard et al, 2014 ; Kim et al, 2018 ).…”

“…MiR165/166 mediates methylation of downstream coding sequences of their target genes PHABULOSA and PHAVOLUTA in Arabidopsis ( Bao et al, 2004 ). MiR156 and its target genes SPLs control transition from juvenile to adult phase in Arabidopsis ( Xu et al, 2018 ; Manuela and Xu, 2020 ). MIR156A and MIR156C loci are major contributors to the formation of mature miR156.…”
