Summary: This study found that only three mutations are needed to change the ligand preference of the KAI2 receptor, allowing it to recognize strigolactone hormones. The modified receptor still retains it native function to perceive KAI2 ligands. The research indicates that only a few key mutations are required to increase the receptor promiscuity of KAI2.

Summary: In this study, the SLs signaling gene GhMAX2 was identified and its function in plant growth and architecture in cotton was demonstrated. Bioinformatics analysis and subcellular localization revealed that GhMAX2 was highly expressed in cotton and targeted to the nucleus. Knockdown expression of GhMAX2 resulted in significantly reduced plant height, slow growth, short internodes, and reduced fiber length in cotton. These findings suggest that GhMAX2 contributes to plant growth, architecture, and fiber elongation in cotton.

Summary: Strigolactones, initially known as germination stimulants for certain plants, have been found to play crucial roles in various aspects of plant growth and defense. They interact with other phytohormones and are involved in root and shoot architecture, pathogen interaction, and nutrient uptake. Furthermore, Strigolactones have been identified as important factors in abiotic and biotic stress tolerance. This review highlights the importance of understanding Strigolactones and their complex interaction networks for crop improvement and modern agriculture.

Summary: The activities of three series of novel GR24 derivatives in hypocotyl and root development of Arabidopsis were explored. Among the synthesized compounds, A11a, A12a, and A20d showed high activities similar to GR24 in inhibiting hypocotyl and/or primary root elongation in Arabidopsis. Additionally, some new analogues exhibited unique activities.

Summary: A novel juvenile hormone (JH) signaling inhibitor, ethyl (E)-3-(4-{[7-(4-methoxycarbonylbenzyloxy)-1,4-benzodioxan-6-yl]methyl}phenyl)prop-2-enoate (EMBP), was discovered to induce precocious metamorphosis in silkworm larvae by specifically inhibiting the expression of Kr-h1, a JH early response gene. This study provides insights into the mechanism of action of EMBP in the JH-mediated signaling pathway and highlights its potential as a lead compound for the development of new insect growth regulators.

Summary: In this study, hexacyclic pyrazolamide derivatives were designed and synthesized as novel insect growth regulators targeting Ecdysone receptor (EcR) and chitinase. The insecticidal activity was improved by inserting an additional methylene spacer between the substituted phenyl ring and the amide bond. Compound 6j showed promising insecticidal activities against Plutella xylostella and Spodoptera frugiperda and targeted both EcR and OfChtI. This research provides valuable clues for the development of new dual-target insect growth regulators.

Summary: Insect growth regulators (IGRs) are considered as green insecticides for disrupting normal physiological processes in insects. In this study, the lead compound a12 was identified as a promising multitarget inhibitor. By studying the binding modes of a12 with three chitinases, the critical interactions and favorable residues were recognized for the bioactivity. A series of benzo-[d]-[1,3]-dioxole-6-benzamide derivatives were then designed and synthesized to improve the bioactivity. Compound d29 showed significantly improved inhibitory activity against Ostrinia furnacalis chitinases and demonstrated superior insecticidal activity against O. furnacalis and Plutella xylostella.

Summary: Strigolactones (SLs) play important roles in the developmental processes of plants, including shoot branching, growth regulation, and root morphology. They are involved in plant responses to nitrogen and phosphorus starvation, and participate in plant stress adaptation governed by phytohormones. Furthermore, the potential of SLs in remediation of heavy metal-contaminated soil has not been fully understood yet.

Summary: Small molecule hormones play a central role in plant development by regulating multiple processes. Despite being canalized through a core pathway, the question remains on how different outputs can be produced in various tissues. Recent studies have revealed alternative mechanisms for regulating downstream signaling components, potentially explaining the diverse developmental responses to the same hormone.
