The hormones auxin and cytokinin are essential for plant growth and development. Because of the central importance of root and shoot apical meristems in plant growth, auxin/cytokinin interactions have been predominantly analyzed in relation to apical meristem formation and function. In contrast, the auxin/cytokinin interactions during organ growth ...

Stem cells (SCs) are undifferentiated cells of multicellular organisms that can divide, self-renew, and differentiate. Despite the differences in their properties, the general principles of the existence of SCs can be distinguished in all multicellular organisms. In plants, SCs are found in meristems, structures that ensure the continuous growth of...
The complete uprooting of diseased mats/fields (CMU) is one of the recommended control options for Xanthomonas wilt of banana. CMU is labour intensive, time consuming and disturbs the soil structure, exposing fields to erosion. CMU often involves exportation of whole plant biomass, affecting soil fertility. The potential of continuous cutting at so...

Plants produce new organs from a population of pluripotent cells which are located in specific tissues called meristems. One of these meristems, the shoot apical meristem (SAM), gives rise to leaves during the vegetative phase and flowers during the reproductive phase. The transition from vegetative SAM to an inflorescence meristem (IM) is a dramat...

Common wheat is a widely planted cereal in China, and vernalization is a crucial phase in wheat development. Although three major genes (VRN1, VRN2 and VRN3) are associated with the vernalization response, little is known about their expression profiles during wheat growth. In this study, we observed the spike differentiation process in spring whea...
The objective of this study was to determine the relationship between foliar emission and floral differentiation in False Horn plantains. Four studies were carried out on the Caribbean coast of Costa Rica between November 2000 and January 2014. Recoded variables were type and number of emitted leaves. In Study I (tall and dwarf cultivars, first rat...
Abstract During the life cycle, a plant undergoes a series of developmental phase changes. The first phase change is the transition from the initial juvenile vegetative stage into the adult vegetative phase. During the juvenile phase plants produce leaves and axillary buds, whereas during the adult phase the initiation of reproductive structures oc...

The division of the apical meristem into two independently functioning axes is defined as dichotomous branching. This type of branching typically occurs in non-vascular and non-seed vascular plants, whereas in seed plants it presents a primary growth form only in several taxa. Dichotomy is a complex process, which requires a re-organization of the ...
Phyllotaxis, the spatio-temporal pattern of organogenesis at the shoot apical meristem, emerges in large part from inhibitory fields consisting in auxin-depleted areas centered on organs. We recently demonstrated the existence of an additional hormone-based inhibitory field generated by Arabidopsis Histidine Phosphotransfer Protein 6 (AHP6), an inh...
