Summary: Plant small peptides, including CLE and EPFL, play crucial roles in cell-cell communication to coordinate developmental processes, especially in vascular development. Different sources of peptides, such as CLE and EPFL, have specific regulatory effects on plant growth and development.

Summary: This study reveals a synergistic relationship between auxin biosynthesis and cellular auxin efflux in leaf vein development, explaining the formation of midvein morphology through computational modeling. The findings suggest that the site-specific accumulation of auxin, regulated by the balanced action of cellular auxin efflux and local auxin biosynthesis, is crucial for leaf vein formation.

Summary: RAV1 gene plays an important role in regulating root growth. The expression of RAV1 gene is suppressed in mutant, resulting in impaired cytokinin signaling and altered auxin transport and distribution, ultimately affecting the meristem size of the root.

Summary: Extreme environmental changes pose a threat to plant survival and global food production. The plant hormone abscisic acid (ABA) is activated in response to osmotic stress and inhibits plant growth. However, the epigenetic regulation of ABA signaling and its interaction with auxin are not well understood.

Summary: During root exploration, roots adapt to different conditions and interact with their environment. Asymmetric molecular patterns guide directional root growth, but the mechanisms of their establishment and dynamic regulation are not well understood. Asymmetric gradients of the phytohormone auxin are established through polarized auxin transporters, mainly during root gravitropism. GOLVEN-ROOT GROWTH FACTOR 1 INSENSITIVE signaling in lateral root cap cells plays a crucial role in root gravitropism by regulating the plasma membrane abundance of PIN-FORMED2 in Arabidopsis.

Summary: The study reveals that the change in plant root architecture is regulated by potassium ion (K+) deprivation through a reduction in cell division rate in lateral root meristems, primarily mediated by gibberellic acid (GA) signaling. Transcriptomic analysis showed that transcription factors JUB1 and CBF1, as well as the CBF1 target gene SFR6, play crucial roles in the response to K+ deprivation in lateral root growth.

Summary: The plant hormone auxin is central to plant growth and development, with protein phosphorylation emerging as a crucial post-translational modification type regulating auxin output. This review comprehensively discusses the genetics, biochemistry, and cell biology of kinases and phosphatases involved in auxin action, providing insights into the mechanisms of developmental auxin responses and future directions for integrating protein phosphorylation control into the molecular auxin network.

Summary: A female-to-male transition mutant was discovered in melon, and the causal gene was identified as the carpel identity gene CRABS CLAW (CRC). The master regulator of sex determination, transcription factor WIP1, recruits the corepressor TOPLESS to suppress CRC expression, leading to male flower development. Impairing the physical interaction between TOPLESS and WIP1 results in CRC expression, carpel determination, and ultimately the development of female flowers.

Summary: This study reveals the interplay between the calcium signaling module and auxin signaling in Arabidopsis, showing their important roles in callus and lateral root formation. The physical interaction between CaM-IQM and IAA proteins in a calcium-dependent manner is found to regulate auxin-induced callus formation.

Summary: Salt stress has distinct effects on the root xylem development of Arabidopsis seedlings, leading to the formation of protoxylem gaps. The extent of protoxylem gaps positively correlates with salt tolerance. Reduced gibberellin signaling and the involvement of various genes are required for the formation of protoxylem gaps. These findings provide important insights into the acclimation of plants to high salt conditions.
