Summary: Auxin-mediated degradation of Aux/IAA proteins is crucial in auxin signaling and also plays a role in response to biotic and abiotic stresses. The study showed that GhIAA43 in cotton acts as a negative regulator in defense against Verticillium dahliae attack by activating SA-related defenses, leading to enhanced resistance. Additionally, exogenous IAA application improved wilt resistance in cotton plants.

Summary: This study identifies the negative regulator MdARF5-1 in apple as a component of the auxin signaling pathway that inhibits anthocyanin biosynthesis by suppressing the expression of the ethylene response factor MdERF3. The auxin repressor MdIAA29 attenuates the inhibitory effect of MdARF5-1 on anthocyanin biosynthesis by alleviating the transcriptional inhibition of MdERF3. Furthermore, the E3 ubiquitin ligases MdSINA4 and MdSINA11 regulate anthocyanin biosynthesis by targeting MdIAA29 and MdARF5-1 for ubiquitination degradation, respectively.

Summary: The iaaL alleles in P. savastanoi determine the production of IAA-Lys. iaaL(Psn) and iaaL(Psf) genes control the production of IAA-Lys in pv. savastanoi and pv. fraxini, respectively. Overexpression of these genes reduces the free IAA content and alleviates the inhibitory effect of IAA on plant root growth.

Summary: The levels of the important plant growth regulator IAA are tightly controlled within plant tissues through metabolic inactivation, modulation of concentration gradients, and glycosylation processes; UGT84B1 and UGT74D1 have been identified as key enzymes in the glycosylation of IAA and oxIAA, which play crucial roles in regulating plant growth and development. Additionally, a novel UGT subfamily has been discovered to redundantly mediate the glycosylation of oxIAA and modulate skotomorphogenic growth.

Summary: This study demonstrates that GH3 acyl acid amidosynthetase is able to catalyze the formation of high molecular weight IAA conjugates with proteins. The enzyme exhibits a preference for the formation of IAA-Asp, but specific substrates like L-Asp can down-regulate the conjugation process. Additionally, competition with specific substrates like L-Trp can inhibit the enzyme's activity.

Summary: In this study, the authors identified and analyzed 33 PsIAAs and 35 PsARFs genes in Populus simonii. They found that these genes were unevenly distributed on chromosomes and could be classified into different subgroups. The expression analysis showed that these genes exhibited different expression patterns in various tissues and stress conditions. The PsIAA7 gene was identified as a central hub in the gene network. The findings of this study provide valuable insights into the roles of PsIAA and PsARF gene families in the development and stress responses of P. simonii.

Summary: The passage discusses the infection mechanisms of sedentary endoparasites like cyst and root-knot nematodes on important food crops, highlighting the importance of plant hormones such as indole-3-acetic acid (IAA) in the formation of feeding structures. It also points out the complexity of the molecular and biochemical mechanisms underlying these interactions and suggests potential roles for other auxins in plant-parasitic nematode infections that require further investigation.

Summary: E3 ubiquitin ligases are crucial in plant biology and play a key role in the perception and signaling of hormones. The redox modification of proteins through S-nitrosation serves as an important regulatory mechanism in hormonal signaling pathways. This study confirmed the S-nitrosation of TIR1 and COI1, highlighting the functional relevance of this modification in the response to auxins and jasmonates.
