Plant development

Plant development is the process by which structures originate and mature as a plant grows. Plants produce new tissues and structures throughout their life from clusters of undifferentiated cells called meristems.

    Plant microtubules align along directions of anisotropic mechanical stress. Live cell imaging of epidermal pavement cells reveals that cellulose synthase complexes (CSCs) are present in regions of anisotropic mechanical stress in patterns similar to those of microtubules. The coupling of microtubules and CSCs hampers the response of microtubules to mechanical stresses.

    Cellular responses to environmental and developmental signals depend on the recruitment of transcription factors to specific genes. Although PIF4 and CDF2 belong to different transcription factor families in Arabidopsis thaliana, data suggest that they act co-operatively to bind to specific target genes in the gene network that regulates hypocotyl cell elongation.

    Grain yield in bread wheat (Triticum aestivum L.) is largely determined by spike architecture. Mutations in DUO-B1, encoding an AP2/ERF protein, result in a spike architecture with extra spikelets that increases both grain number per spike and yield under field conditions. Genetically modifying DUO-B1 has the potential to increase cereal production.

    Regulation of organ growth involves multiple pathways that coordinate cell number and size in a process that is highly dependent on nutrient supply and energy levels. The simplicity of the Arabidopsis root tip provides a suitable model for the genetic dissection of plant organ growth regulation.
