Summary: The study reveals the role of two barley proteins HvYDA1 and HvBRX-Solo in regulating cuticular properties and epidermal patterning. These proteins control the spacing and identity of epidermal cells, as well as the integrity of the cuticle and stomatal patterning in barley. Genetic analyses indicate that HvYDA1 and HvBRX-Solo have epistatic and modifying relationships, suggesting their involvement in interacting pathways linking epidermal patterning with cuticular properties in barley.

Summary: The study revealed that Arabidopsis AtPRP17, a homolog of yeast splicing factor gene PRP17, plays a crucial role in embryo development by regulating embryonic patterning. Loss-of-function mutation of AtPRP17 led to shrunken seeds in Arabidopsis mature siliques with defective embryos showing delayed development and abnormal patterning. This suggests that AtPRP17 functions in Arabidopsis embryo development through regulation of embryonic patterning.

Summary: By studying the wild plants Rhodiola rosea, Boehmeria nivea, and Cucumis sativus, it was found that R. rosea and B. nivea belong to the Type III root hair cell distribution pattern, while C. sativus belongs to the Type I pattern. There are significant similarities in the structure, expression, and function of Arabidopsis patterning gene homologs in R. rosea and B. nivea, while major changes were observed in C. sativus. It is proposed that different Type III species in superrosids inherited the patterning gene regulatory network from a common ancestor, while Type I species arose through mutations in multiple lineages.

Summary: Phytohormones play essential roles in regulating stomatal development and patterning in plants, with different organ responses to phytohormones observed in Arabidopsis. Current research focuses on understanding how distinct hormonal signaling circuits integrate into core stomatal development pathways and how different phytohormones interact to modify stomatal density and spacing patterns. Insights from Arabidopsis research may offer pathways for studying the effects of phytohormones on regulating stomatal development in cereal grasses to enhance crop adaptation responses.

Summary: The search for genetic regulators of leaf venation patterning started over 30 years ago, primarily focused on mutant screens in Arabidopsis thaliana. Recently, a potential regulator was identified in maize leaves, but further studies in Arabidopsis showed no obvious phenotypic perturbations. Re-evaluation of previous mutations revealed potential problems in the reported mutations.

Summary: In this study, the crucial role of CDC48B in regulating periclinal cell division in roots was revealed. Loss of function of CDC48B led to increased periclinal cell division, defective middle cortex formation, and altered ground tissue patterning in roots. The findings also showed that CDC48B plays a role in regulating the intercellular trafficking of SHR during periclinal cell division in roots.

Summary: The research shows that the low-carbon city policy can improve the overall carbon emission efficiency in pilot cities. Findings suggest that while existing studies argue that the policy can reduce the carbon emission of pilot cities immediately, in reality, it takes longer to improve carbon emission efficiency. Factors influencing this efficiency include the proportion of secondary industry, energy intensity, capital-labor ratio, and research investment. The policy may deepen the urban divide between eastern and western regions and the mechanisms through which it takes effect have been discussed.

Summary: This study investigated the different effects of calcitriol in modulating T cell immunity of age-matched male and female healthy donors. The results showed that calcitriol increased vitamin D receptor expression levels and reduced pro-inflammatory cytokine expression levels in T lymphocytes of both sexes. Furthermore, calcitriol only increased the expression level of the anti-inflammatory cytokine IL-10 in T lymphocytes from female healthy donors. These findings provide new insights into the sex-specific anti-inflammatory role of calcitriol in T cell immunity.

Summary: The study investigates the mechanism of generating positional information for organ determination during early stages of flower development, integrating a previous model for the emergence of WUS pattern in the floral meristem. It predicts that LFY diffusion along the L1 layer of cells is not a necessary condition for patterning of the floral meristem.

Summary: ULT1 is a versatile plant-specific protein that can regulate transcription activation independently of ATX1. It interacts with transcription factors and PcG proteins, indicating diverse roles. ULT1 acts as an epigenetic molecular switch regulating repression and activation processes via TrxG and PcG complexes.

Summary: The root stem cell niche in Arabidopsis thaliana is composed of quiescent center cells and surrounding initial stem cells, with hormone signaling and transcriptional regulatory networks interacting to control root growth and development. This complex genetic-hormonal regulatory network can reshape root tissues based on the plant's needs, acting as integrators of environmental cues to impact on stem cell niche activity.

Summary: The growth of multicellular organisms relies on the balance between cell proliferation and differentiation, which is tightly regulated by internal and external stimuli. Plant hormones play crucial roles in Arabidopsis primary root development, sometimes exhibiting synergistic effects and sometimes resulting in unexpected outcomes. Further research on the molecular mechanisms governing hormone crosstalk in specific zones and domains will provide insights into their coordination during primary root development.

Summary: Current therapeutic strategies and vaccines against SARS-CoV-2 mainly focus on the Spike protein, but other viral proteins like ORF8 also play important roles in COVID-19 pathogenicity. By analyzing the structural similarities of ORF8 with immunological molecules such as IL-1, we can gain insights into the immunological deregulation observed in COVID-19 and propose that blocking certain effector functions of ORF8 with Rapamycin could be a promising approach to reduce COVID-19 mortality.

Summary: Mexico is one of the origins of maize, and transgene presence poses a threat to maize conservation. Despite previous studies confirming the presence of transgenes in Mexican landraces, there is currently no nationwide transgene monitoring protocol, nor systematic analyses on factors related to transgene presence and dispersal. This study proposes a geographically representative sampling protocol and presents empirical data from three states in Mexico. Real-Time PCR is used to assess transgene presence in collected maize samples, and the results show widespread distribution of transgenes across the sampled localities. The data mining approach identifies state-specific spatial associations related to transgene presence. The study emphasizes the importance of implementing a national biomonitoring protocol to increase understanding of the sources that enable transgene presence and dispersal.

Summary: Modularity is crucial in adaptive complex systems, with phenotypic traits as modules that can vary independently. The genotype-phenotype map is proposed to be functionally modular, and dynamical modularity may be more widely applicable than structural decomposition. This approach provides a shared conceptual foundation for developmental and evolutionary biology, and offers a new account of process homology.

Summary: Gene essentiality estimation is a popular empirical method that links genotypes to phenotypes, showing that it can recover functional constraints of genes, but estimates based on organismal or cellular contexts may result in different functional constraint properties. Information obtained from LoF mutations effectively captures organismal-level functional constraints, with some genes showing a preference for nervous system expression despite being intolerant in vivo and tolerant in vitro.
