Summary: Plants face various biotic and abiotic stresses in their changing environments. They use different signaling molecules and pathways to respond to these stresses. Reactive oxygen species (ROS) play a crucial role in plant stress responses. Plants can activate distinct stress signaling pathways in response to multiple stresses. This study analyzed gene expression and publicly available datasets to identify signaling pathways regulated by ozone and high light treatment, and found different responses between these two treatments.

Summary: This study investigates the water transport properties of highly branched root systems in adult Arabidopsis plants and reveals the overestimation of axial conductivities. By developing a hydraulic model and conducting simulations and experiments, the study also uncovers the growth and water transport mechanisms of Arabidopsis root systems. This approach is instrumental in understanding the root water transport phenotype of plants with complex alterations in root growth or transport functions.

Summary: In this study, a genotype to phenotype prediction using comparative transcriptome analysis was established to study multigene regulation in Arabidopsis thaliana. The results showed that the differences in gene expression between different ecotypes were smaller compared to those between different organs. Gene Ontology analysis revealed a number of genes enriched in response to cold, abscisic acid stimulus, and hormone stimulus. Further experiments confirmed that the Col-0 ecotype exhibited more tolerance to cold stress and abscisic acid. These differentially expressed genes provide insights into the understanding of plant growth, development, and response to environments.

Summary: In plants, priming allows for a more rapid and robust response to recurring stresses. However, less is known about how priming due to one stress can help plants cope with subsequent different stresses. This study investigated the priming effects in Arabidopsis plants subjected to high light (HL) stress followed by drought (D) stress, and found that HL can mediate transcriptional priming and enhance plant responses to stress.

Summary: Inhibition of AtTOR gene increases ABA content and activates ABA-responsive genes, while ABI5 interacts with S6K2 to positively regulate ABA responses during seedling growth in Arabidopsis. Overexpression of AtS6K2 enhances drought resistance, indicating a crosstalk between TOR and ABA signaling pathways in modulating seedling growth.

Summary: It has been shown that moderate drought stress increases the susceptibility of Arabidopsis thaliana to bacterial pathogens, and that drought and bacterial stress antagonistically modulate a large set of genes through the SA and ABA signaling networks. Under combined stress, drought downregulates the induction of SA production through the ABA pathway, impacting plant defense against bacterial pathogens.

Summary: Polyamine metabolism in plants is controlled by multiple genes which are differentially regulated under different physiological conditions. Our study in Arabidopsis thaliana revealed that most genes in polyamine metabolism are not responsive to exogenous polyamines, but there is a difference in response to polyamines between Arabidopsis and rice, as shown by the induction of OsPAO6 gene. These results provide a framework for further study of regulatory modules controlling the expression of each polyamine metabolic gene.

Summary: The study identified Raf36 and Raf22 protein kinases in plants as regulators of ABA signal transduction under multiple mechanisms to suppress ABA response. Through a series of experiments, it was found that they regulate ABA response through phosphorylation and other mechanisms under ABA stimulation, playing an important role in plants' adaptation to stress conditions.

Summary: The study found that exogenously applied ABA can suppress the formation of adventitious roots in Arabidopsis, while the synthetic ABA analog PB exhibits a stronger inhibitory effect. Additionally, analysis of various pyrabactin analogs suggests that adventitious root formation and lateral root branching are regulated differently by ABA signaling, with PYL1 and PYL2 identified as candidate ABA receptors that control AR inhibition.

Summary: Suberin, a complex polyester, plays a role in controlling the movement of water, ions, and gas in the seed coat outer integument. This study investigated the role of the plant hormone abscisic acid (ABA) in suberin layer formation during seed coat development. The results showed that ABA is important for regulating the permeability of the seed coat.

Summary: A nodule circadian clock coordinates metabolic and regulatory activity during symbiosis by involving the gene Late Elongated Hypocotyl and rhythmic expression of nodule-specific cysteine-rich peptides. The rhythmic expression of these peptides may play a vital role in temporal coordination between bacterial activity and the rhythms of the plant host.

Summary: This study characterized the symbiotic phenotypes of four Medicago truncatula mutants and identified two genes, RAM1 and KIN3, involved in mycorrhization. The results showed that RAM1 acts upstream of KIN3 and that KIN3 is involved in suppressing plant defenses and promoting root colonization. KIN3 also plays an essential role in the symbiotic response to soil nitrogen levels.

Summary: Stipule morphology is an important feature for plant identification, but its molecular regulation is not well understood. This study identifies a gene involved in stipule identity and investigates its interactions with other genes. The findings propose a genetic regulatory model for stipule development, explaining the two phases of stipule development.

Summary: Legumes regulate nodulation through the expression and regulation of MtNRT2.1, MtNLP1, and MtCEP1. MtNRT2.1 affects nodulation differently in low- and high-nitrate conditions, with MtNLP1 promoting its expression under low-nitrate conditions and suppressing it under high-nitrate conditions. MtCEP1 independently enhances nodulation by increasing the expression of NRT2.1 under low-nitrate conditions.

Summary: In cotton plants, both FAAH and LOX enzymes are involved in the metabolism and regulation of 9-NAE-HOD, which negatively affects seedling growth. Silencing FAAH genes leads to elevated levels of 9-NAE-HOD and inhibited seedling growth, while silencing LOX genes reverses this effect. These findings expand our understanding of plant growth modulation by NAE oxylipins.

Summary: This study investigated the relationship between senescence and immunity in Medicago nodules. It found that in nonfunctional nodules, senescence and immunity appear to be antagonistic, while in normal nodules under stress, they switch to a synergistic relationship. The study also identified key genes involved in symbiotic immunity suppression. Understanding the links between senescence and immunity in nodules contributes to the knowledge of nodule organogenesis.

Summary: This study reveals the presence of a second Nod factor cleaving hydrolase (MtCHIT5b) in Medicago truncatula, which degrades Sinorhizobium meliloti Nod factors in the rhizosphere in conjunction with MtNFH1. The expression of MtCHIT5b is induced by purified Nod factors treatment or rhizobia inoculation, and it is localized in the infection pocket of root hairs. The study also demonstrates that overexpression of MtCHIT5b leads to reduced nodule formation, and simultaneous silencing of MtCHIT5b and MtNFH1 results in decreased nodulation.

Summary: A library of glycan-directed antibodies was used to study cell wall modifications in plants under low-gravity conditions. The results showed global differences in cell wall epitopes between plants grown in space and ground controls. Immunohistochemistry confirmed that certain antibodies labeled space-grown roots more intensely, indicating accelerated secondary cell wall formation. This study demonstrates the feasibility of glycomics for evaluating plant cell wall glycans and uncovering microgravity-induced changes in tissue-specific cell walls.
