Summary: Nitric oxide (NO) plays important roles in both host-pathogen interactions and symbiotic interactions. Pathogens have evolved mechanisms to adapt to or degrade NO, while NO produced by pathogens also contributes to the success of host cell infection. In nitrogen-fixing symbiosis, NO has various roles, but the specificity of NO produced by each participant is not well understood.

Summary: Three previously unreported ABC subfamily B transporters, named AMN1, AMN2, and AMN3, are strongly expressed in symbiotically infected tissues, with critical roles in nodulation and mycorrhization. Further studies are needed to identify potential substrates of these transporters and understand their roles in beneficial symbioses.

Summary: Novel nodulation-suppressing CLE peptides MtCLE34 and MtCLE35 were identified in legumes, showing different responses to rhizobia and nitrate. MtCLE12 and MtCLE13 are specific to autoregulation of nodulation, while MtCLE35 regulates nodule numbers in response to both rhizobia and nitrate. MtCLE34 was found to be a pseudogene with a non-functional CLE-domain due to a premature nonsense mutation.

Summary: For many years, the scientific community focused on understanding how rhizobia promote the growth of legumes through nitrogen fixation. However, recent research has shown that rhizobia can also stimulate the growth of non-legume plants through various mechanisms such as hormone production, nutrient uptake improvement, pathogen control, and water regulation. This review aims to analyze the existing knowledge on how rhizobia promote the growth of non-legumes and gain new insights into their interactions.

Summary: Aquaporins are key players in multiple aspects of plant growth and development, as well as stress resistance. In this study, 43 MsAQP genes were identified in Medicago sativa, clustered into four subfamilies. Analysis revealed that majority of the MsAQP proteins contained important structural domains and various stress-responsive and hormone-responsive elements. Ten salt- or drought-responsive AQP genes were identified and their differential expression in response to stress was observed in Medicago sativa.

Summary: This study investigated the allocation to growth, reproduction, and defence in maritime pine under different resource availability and simulated herbivory treatments. The results showed that fertilization increased tree growth and seed quantity but not seed quality. Needle clipping and methyl-jasmonate treatment increased needle resin and phenol concentrations. Overall, there were complex interactions among the life-history dimensions, suggesting that pairwise approaches are insufficient to unravel these complexities.

Summary: The xanthophyll cycle plays a significant role in protecting plants from membrane peroxidation induced by intense light exposure. This study identified 240 differentially expressed genes associated with respiratory chain, lipid metabolism, antioxidant activity, and flavonoid metabolism. The overexpression of the CmBCH1 gene resulted in the upregulation of genes involved in scavenging reactive oxygen species and encoding antioxidants, leading to the accumulation of xanthophyll, zeaxanthin, chlorophylls, and anthocyanins. The study highlighted the potential of BCH1 in regulating the xanthophyll cycle and enhancing tolerance to intense light stress in transgenic plants.

Summary: This study demonstrated that co-expressing two exogenous genes, tfdB and bphC, in Arabidopsis thaliana improved the tolerance and removal efficiency of PCB28. Transgenic plants also exhibited increased enzymatic activities under PCB28 stress. The co-expression of tfdB and bphC in A. thaliana resulted in nearly twofold increase in PCB28 removal rates from soil. This research suggests that co-expressing two genes holds great potential for enhancing phytoremediation efficiency and mitigating PCB-induced toxicity stress on plants.

Summary: Trichomes are specialized plant structures that protect plants and are regulated by complex gene networks and signaling pathways. Gene expression, cell cycle regulation, and differentiation determine whether cells become trichomes. Transcription factors, epigenetic modifications, and phytohormones play important roles in trichome development. The integration of phytohormonal and transcriptional networks contributes to the diversity and adaptability of trichomes in plants.

Summary: The impact of multifactorial abiotic stress combinations on plant functional responses remains controversial. The halophyte Salicornia ramosissima showed unique functional responses depending on the specific stress factors involved. Under extreme conditions, there was a more negative impact on plant functional traits, but the presence of beneficial microorganisms, especially in combination with elevated atmospheric CO2 concentration, mitigated these negative effects.

Summary: In eukaryotic cells, epigenetic modifications of DNA and histones play a crucial role in gene expression regulation. ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.

Summary: This study identified and characterized 163 C2H2-type zinc finger proteins in non-heading Chinese cabbage. Two of these proteins, BcZAT12 and BcZAT10, were found to be closely related to cold tolerance and acted as transcriptional repressors in regulating cold resistance. Furthermore, BcZAT12 was shown to directly bind to the promoter of BcCBF1 and inhibit its activity. Additionally, interactions between BcZAT12 and other proteins such as BcABF2/4 were observed. These findings provide insights into the functional roles and regulatory mechanisms of C2H2-ZFPs in non-heading Chinese cabbage under cold stress.

Summary: The combination of NB and reduced irrigation water depth can mitigate the negative effects of salinity and drought stresses on quinoa and improve its water productivity. The use of NB up to 2% alleviated salinity and drought stress and increased yield, while decreasing salinity and irrigation water depth increased water productivity. The appropriate use of NB can reduce the negative effects of stress and promote the sustainable production of quinoa.

Summary: Soil salinization is a major obstacle for agriculture sustainability, as it severely affects plant growth and crop yield. Ethylene, a stress hormone, plays a crucial role as a signal molecule in coordinating plant growth and stress response in the model plant Arabidopsis. However, the roles and mechanisms of ethylene in most crop plants under salinity remain undefined. This review summarizes the universal roles of ethylene and focuses on its divergent roles in rice and other crop species under salinity, particularly in terms of ethylene biosynthesis and signal transduction. The contradictions between ethylene production and signaling in salt response are also discussed.
