Extracellular perception of auxin, an essential phytohormone in plants, has been debated for decades. Auxin-binding protein 1 (ABP1) physically interacts with quintessential transmembrane kinases (TMKs) and was proposed to act as extracellular auxin receptor, but its role disputed because abp1 knockout mutants lack obvious morphological phenotypes. Here, we identified two new auxin-binding proteins, ABL1 ABL2, that are localized the apoplast directly interact domain TMKs auxin-dependent...
Auxin determines the developmental fate of plant tissues, and local auxin concentration is precisely controlled. The role transport in modulating has been widely studied but regulation biosynthesis less well understood. Here, we show that TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS (TAA1), a key enzyme pathway Arabidopsis thaliana phosphorylated at Threonine 101 (T101). T101 phosphorylation status can act as an on/off switch to control TAA1-dependent required for proper root meristem size...
<p>Rapid auxin responses in plants are crucial initiating cellular changes. These involved processes such as plasma membrane depolarization, cytoplasmic streaming, apoplastic pH changes, calcium influx, etc. Recent studies illustrated how triggers rapid changes protein phosphorylation different species through both the ABP-TMK perception at cell surface and a conserved RAF-like kinase-based mechanism. works uncovered an ancient system for to signaling molecule, shedding light on its...
Gravitropism is an essential adaptive response of land plants. Asymmetric auxin gradients across plant organs, interpreted by multiple signaling components including AUXIN RESPONSE FACTOR7 (ARF7), trigger differential growth and bending response. However, how this fundamental process strictly maintained in nature remains unclear. Here, we report that gravity stimulates the transcription METHYL ESTERASE17 (MES17) along lower side hypocotyl via ARF7-dependent signaling. The asymmetric...
Callus induction, which results in fate transition plant cells, is considered as the first and key step for regeneration. This process can be stimulated different tissues by a callus-inducing medium (CIM), contains high concentration of phytohormone auxin. Although few regulators callus induction have been identified, multiple aspects regulatory mechanism driven levels auxin still need further investigation. Here, we find that induces through H3K36 histone methylation-dependent mechanism,...

Abstract. The Gonghe Basin is a sandified and desertified region of China, but the distribution soil organic carbon (SOC) total nitrogen (TN) along cultivation chronosequence across this ecologically fragile not well understood. This study was carried out to understand effects afforestation with Salix cheilophila for different periods time (6, 11, 16, 21 years) test whether it enhanced C N storage. Soil samples, in four replications from seven depth increments (every 10 cm 0 30 cm, every 20...
Abstract PIN-FORMED (PIN)-driven auxin transport contributes to establishing and maintaining a dynamic concentration gradient alongside plant tissues, which drives the majority of developmental processes in plants. To maintain plasticity ever-changing environments, plants have evolved self-organizing feedback machinery between signaling its transport, has been shown play essential roles many fundamental processes. However, molecular mechanism behind this mutual regulation not yet clarified....
