MicroRNAs (miRNAs) are 20–24 nucleotide noncoding RNAs abundant in plants and
animals. The biogenesis of plant miRNAs involves transcription of miRNA genes, processing …

Auxin plays important roles during the entire life span of a plant. This small organic acid
influences cell division, cell elongation and cell differentiation, and has great impact on the …

Auxin has always been at the forefront of research in plant physiology and development.
Since the earliest contemplations by Julius von Sachs and Charles Darwin, more than a …

The rice root system is important for growth. The crosstalk between auxin and cytokinin
mediates root initiation and elongation. However, it remains unclear how the transcriptional …

Plants adapt to different environmental conditions by constantly forming new organs in
response to morphogenetic signals. Lateral roots branch from the main root in response to …

Root indeterminate growth and its outstanding ability to produce new tissues continuously
make this organ a highly dynamic structure able to respond promptly to external …

The plant hormone auxin is believed to influence almost every aspect of plant growth and
development. Auxin transport, biosynthesis and degradation combine to form gradients of …

Boron (B) is an essential element for plant growth. Many agricultural soils around the globe
have either insufficient or excessive amounts of available B, with major implications for crop …

In land plants comparative genomics has revealed that members of basal lineages share a
common set of transcription factors with the derived flowering plants, despite sharing few …

The functions of microRNAs and their target mRNAs in Arabidopsis thaliana development
have been widely documented; however, roles of stress-responsive microRNAs and their …
