Previously we identified aminooxy compounds as auxin biosynthesis inhibitors. One of the compounds, aminooxyacetic acid (AOA) inhibited indole-3-acetic acid (IAA) biosynthesis in rice and tomato. Here, we found that AOA induced auxin over-accumulation in Arabidopsis. The results suggest that auxin-related metabolic pathways are divergent among these plant species.

Excessive accumulation of auxin inhibits protocorm development during germination of Paphiopedilum spicerianum.

Plant Cell Rep

Excessive auxin accumulation inhibits protocorm development during germination of Paphiopedilum spicerianum, delaying shoot meristem formation by downregulating boundary genes (CUC1, CUC2, CLV3) and promoting fungal colonization, essential for seedling establishment. Paphiopedilum, possess high horticultural and conservational value. Asymbiotic germination is a common propagation method, but high rates of protocorm developmental arrest hinder seedling establishment.

Article Synopsis
  • VPA, commonly prescribed for psychiatric and neurological disorders, may cause kidney injury with chronic use; this study investigates the underlying mechanisms and potential protective strategies.
  • Rats were divided into groups for testing VPA-induced kidney damage and subsequent treatments with indole-3-acetic acid (IAA) and chenodeoxycholic acid (CDCA) to assess their protective effects.
  • Results showed that VPA reduced antioxidant levels and increased inflammatory markers in kidneys, but IAA and CDCA effectively improved these conditions by enhancing antioxidant defenses and reducing inflammation.

Indole 3-acetate and response to therapy in borderline resectable or locally advanced pancreatic cancer.

Article Synopsis
  • A study explored the link between a bacterial metabolite, indole 3-acetate (3-IAA), and chemotherapy response in non-metastatic pancreatic ductal adenocarcinoma (PDAC) patients, building on previous findings in metastatic cases.
  • Researchers measured 3-IAA levels in blood from 124 patients with locally advanced or borderline resectable PDAC before they started chemotherapy, primarily FOLFIRINOX.
  • The results showed no significant association between pre-treatment 3-IAA levels and overall survival, suggesting that the positive effects seen in metastatic cases may not apply to non-metastatic patients, highlighting the need for further research.

Aflatoxin B1 (AFB1) has been recognized as a serious health risk for ruminant animals. From a molecular perspective, indole-3-acid (IAA) possesses the potential to enhance the removal of AFB1 by rumen microbiota. Therefore, this study aims to investigate the impact of different concentrations of IAA on the removal of AFB1 by rumen microbiota using an technique.

Global citrus production has been severely affected by citrus Huanglongbing (HLB) disease, caused by Candidatus Liberibacter asiaticus (Clas), and the development of effective control methods are crucial. This study employed antimicrobial lipopeptide and phytohormone complex powder (L1) prepared from the fermentation broth of the endophytic plant growth promoting bacterium (PGPB) of strain MG-2 to treat Liberibacter asiaticus (Las)-infected ' 'Chun Jian' plants. Real-time fluorescence quantitative polymerase chain reaction (qPCR) and PCR were employed for disease detection.
