Anderson et al. identify a second site modifier that rescues a maize developmental mutant and report that it encodes a homolog of Arabidopsis ENHANCED DISEASE RESISTANCE4, providing insight into the integration of developmental control and immune responses.

Land plants evolved from freshwater streptophytic algae over 450 million years ago and have since separated into morphologically diverse lineages. A key feature in the transition from aquatic to terrestrial life was the development of 3D body plans with lateral organs. In a new preprint, Naramoto and…

Root branching determines the spatial organization of the root and its interaction with the soil. The emergence of lateral roots (LR) is controlled by a complex regulatory network, involving genetic, hormonal and mechanical factors. In this study, Trinh et al. got new insights about PUCHI, a transcription…

Land plants (Tracheophytes), utilize the well-developed vascular tissue for conducting water and other nutrients necessary for plant growth. In Arabidopsis and other land plants, the key player of vascular cell division is well characterized and this includes the TMO5-LHW (TARGET OF MONOPTEROS 5 –…

Plant morphogenesis is a dynamic process that can be modulated in response to environmental cues. In this work, Xiao et al. characterized germination and seedling development in date palm. After germination, the cotyledonary petiole grows, but the embryo development is paused. At early stages of development…

As in animals, plants produce microRNAs that are also key developmental regulators. Unlike some animals, plants are more exposed to environmental factors that alter cellular processes. Ré et al. show here that phenotypic defects produced by loss-of-function mutations in key proteins of Arabidopsis miRNA…

Little is known about the stimuli that regulate time intervals for new leaves production (plastochrone) at the shoot apical meristem (SAM). Oxygen is a diffusible molecule with potential to regulate this process. The use of a micro-scale Clark-type oxygen electrode allowed Weits et al. to measure oxygen…

Land plants (embryophytes) evolved from freshwater charophycean algae over 450 million years ago. The transition from aquatic to terrestrial environments likely required the evolution and expansion of genetic programs controlling three dimensional growth and the formation of tip-growing surface cells…
