Auxin forms spatial gradients that are implicated in organ morphogenesis. However, it is not known how temporal auxin gradients are integrated with the spatial information. In this paper, Galvan-Ampudia, Cerutti et al., showed using a ratiometric quantitative auxin reporter (quantitative DII-VENUS) that…

Stomata are the pores on the plant surface surrounded by a pair of guard cells that control gaseous exchange and water loss. Among the many genes involved in stomatal patterning and development, EPIDERMAL PATTERNING FACTOR 1 (EPF1) and STOMAGEN encode signaling peptides and acts as negative (inhibitor)…

Lateral root starts development starts with an asymmetric cell division in the founder cell. In this study, Fernandez et al. explored the role of peptide signaling this process. The authors started with the previous finding that GOLVEN peptides are involved in lateral root initiation, as overexpression…

Flower development has always been a fascinating field of research in plant biology. While molecular studies in the past focused on regulatory genes involved in the formation of floral organs in model species, current investigations are addressing the genetic determinants underlying the huge variety…

Stomata are the pores surrounded by a pair of guard cells on the plant epidermis that help in gaseous exchange. The number and spacing of stomata are regulated by a series of phosphorylation and de-phosphorylation events of key transcription factors through the mitogen-activated protein kinase (MAPK)…

Colonization of the terrestrial environment by land plants (embryophytes), a monophyletic clade that evolved from freshwater streptophyte algae, forever changed Earth by transforming biogeochemical cycles. The evolution of stomata was a key adaptation that allowed the colonization of terra firma. Present…

Pseudonectaries do not secrete nectar like nectaries. So, what are their ecological functions? Are there any morphological and anatomical differences between them and true nectaries? How do they develop and evolve? Liao et al. examined pseudonectaries of Nigella damascene to answer these questions. The…

Roots have many specialized cells arranged in concentric circles that are functionally homologous among various plant species but with varying cell-type-specific developmental programs. To further understand these developmental programs, Kajala et al. performed TRAPseq (Translating Ribosome Affinity…
