Auxin is a crucial phytohormone that has various effects on the regulators of plant growth
and development. Auxin signal transduction is mainly controlled by two gene families: auxin …

Phytohormones participate in various processes over the course of a plant's lifecycle. In
addition to the five classical phytohormones (auxins, cytokinins, gibberellins, abscisic acid …

Plants maintain the ability to form lateral appendages throughout their life cycle and form
leaves as the principal lateral appendages of the stem. Leaves initiate at the peripheral zone …

Crop breeding heavily relies on natural genetic variation. However, additional new
variations are desired to meet the increasing human demand. Inflorescence architecture …

A key challenge in biology is to understand how the regional control of cell growth gives rise
to final organ forms. Plant leaves must coordinate growth along both the proximodistal and …

Auxin contributes to almost every aspect of plant development and metabolism as well as
the transport and signalling of auxin-shaped plant growth and morphogenesis in response …

Leaf growth initiates in the peripheral region of the meristem at the apex of the stem,
eventually forming flat structures. Leaves are pivotal organs in plants, serving as the primary …

Auxin response factors (ARFs) are an important family of transcription factors involved in the
exertion of auxin in plants and play a key role in regulating the growth and development of …

Plant organs can adopt a wide range of shapes, resulting from highly directional cell growth
and divisions. We focus here on leaves and leaf-like organs in Arabidopsis and tomato …
