Abstract A series of Ir–PCP pincer precatalysts [(7–6–7‐ R PCP)Ir(H)(Cl)] and Ar PCP)Ir(H)(Cl)(MeCN)] bearing a novel “7–6–7” fused‐ring skeleton have been synthesized based upon the postulate that catalytic species would durability due to their rather rigid structure high activity owing low but sufficient flexibility backbones, which are not completely fixed. Treatment these with NaO t Bu gave rise active 14 electron (14e) i Pr PCP)Ir] Ph PCP)Ir], can trap hydrogen were spectroscopically...

Summary Hakea laurina , a woody Proteaceae, naturally occurs in severely phosphorus (P)‐impoverished habitats southwest Australia. It develops distinctive cluster roots that exhibit high capacity for carboxylate exudation and acid phosphatase activity, contributing to its P acquisition. However, the molecular mechanisms underlying these physiological functions remain poorly understood. We explored cluster‐root transcriptome using de novo RNA‐Seq identified Aluminum‐activated Malate...

White lupin (Lupinus albus L.) plants are tolerant under phosphorus (P)deficiency. They form unique morphological roots, so-called cluster roots (CRs) P deficiency. CRs contribute to absorption by the expansion of root surface area and mobilization activities. Previous research has implied involvement several hormonal functions in CR formation. Ethylene is a key regulator responsible for modification architecture acquisition response low plants. However, understanding effect ethylene on...

Phosphorus (P) is a crucial nutrient for plant growth, but its availability in soils often limited. Invasive plants have shown enhanced utilization of essential elements soil, including P, compared to native plants, contributing their success. This study investigated the responses Triadic sebifera, an invasive species, low P conditions. We T. sebifera with Mallotus japonicus and other local field conditions further examined sebifera's response using hydroponic systems RNA-seq analysis. The...

In the title compounds [C 23 H 22 S 2 , (I), and C 24 (II)], thio-bridging chains on either side of benzene ring (A) are oriented anti to each other. Ring A is located nearly perpendicular other rings (B B') give a short contact between an atom center B (B'). The moieties in (I) (II) seem be almost strain-free.
