Leaves and glumes act as lateral organs and have essential effects on photosynthesis and seed morphology,thus affecting yield.However,the molecular mechanisms controlling their polarity development in rice still need further study.Here,we isolated a polarity defect of lateral organs 1(pdl1)mutant in rice,which exhibits twisted/filamentous-shaped leaves and cracked/filamentous-shaped lemmas caused by defects in polarity development.PDL1 encodes a SUPPRESSOR OF GENE SILENCING 3 protein localized in the cytoplasmic granules.PDL1 is expressed in the shoot apical meristem,inflorescence meristem,floral meristem,and lateral organs including leaves and floral organs.PDL1 is involved in the synthesis of tasiR-ARF,which may subsequently modulate the expression of OsARFs.Meanwhile,the expression levels of abaxial miR165/166 and the adaxial identity genes OSHBs were respectively increased and reduced significantly.The results of this study clarify the molecular mechanism by which PDL1-mediated tasiR-ARF synthesis regulates the lateral organ polarity development in rice. 展开更多

Rice blast,caused by Magnaporthe oryzae,is a fungal disease that causes devastating damage to rice production worldwide.During infection,pathogens secrete effector proteins that modulate plant immunity.Disulfide bond formation catalyzed by protein disulfide isomerases(PDI)is essential for protein folding and maturation.However,the biological function of Pdi1 in M.oryzae has not yet been characterized.In this study,we identified the endoplasmic reticulum(ER)-located protein,MoPdi1,in M.oryzae.MoPdi1 regulates conidiation,cell wall stress,and pathogenicity of M.oryzae.Furthermore,the CGHC active sites in the a and a'redox domain of MoPdi1 were essential for the biological function of MoPDI1.Further tests demonstrated that MoPdi1 was involved in the regulation of ER stress and positively regulated ER phagy.We also found that MoPdi1 interacted with MoHut1.Deletion of MoPDI1 led to the bereft of MoHut1 dimerization,which depends on the formation of disulfide bonds.In addition,MoPdi1 affected the normal secretion of the cytoplasmic effector AVR-Pia.We provided evidence that MoHut1 is important for the vegetative growth,conidiation,and pathogenicity in M.oryzae.Therefore,our findings could provide a suitable target point for designing antifungal agrochemicals against rice blast fungus. 展开更多

Neurodevelopmental processes represent a finely tuned interplay between genetic and environmental factors,shaping the dynamic landscape of the developing brain.A major component of the developing brain that enables this dynamic is the white matter(WM),known to be affected in neurodevelopmental disorders(NDDs)(Rokach et al.,2024).WM formation is mediated by myelination,a multifactorial process driven by neuro-glia interactions dependent on proper neuronal functionality(Simons and Trajkovic,2006).Another key aspect of neurodevelopmental abnormalities involves neuronal dynamics and function,with recent advances significantly enhancing our understanding of both neuronal and glial mitochondrial function(Devine and Kittler,2018;Rojas-Charry et al.,2021).Energy homeostasis in neurons,attributed largely to mitochondrial function,is critical for proper functionality and interactions with oligodendrocytes(OLs),the cells forming myelin in the brain’s WM.We herein discuss the interplay between these processes and speculate on potential dysfunction in NDDs. 展开更多

This study examines the methods to plan the development of offshore oilfields over the years,which are used to support the decision-making on the development of offshore oilfields.About 100 papers are analysed and categorised into different groups of main early-stage decisions.The present study stands in contrast to the contributions of the operations research and system engineering review articles,on the one hand,and the petroleum engineering review articles,on the other.This is because it does not focus on one methodological approach,nor does it limit the literature analysis by offshore oilfield characteristics.Consequently,the present analysis may offer valuable insights,for instance,by identifying environmental planning decisions as a recent yet highly significant concern that is currently being imposed on decision-making process.Thus,it is evident that the incorporation of safety criteria within the technical-economic decision-making process for the design of production systems would be a crucial requirement at development phase. 展开更多

The mechanistic target of rapamycin(m TOR) is a serine/threonine kinase that plays a pivotal role in cellular growth, proliferation, survival, and metabolism. In the central nervous system(CNS), the mTOR pathway regulates diverse aspects of neural development and function. Genetic mutations within the m TOR pathway lead to severe neurodevelopmental disorders, collectively known as “mTORopathies”(Crino, 2020). Dysfunctions of m TOR, including both its hyperactivation and hypoactivation, have also been implicated in a wide spectrum of other neurodevelopmental and neurodegenerative conditions, highlighting its importance in CNS health. 展开更多

Motor neuron diseases are sporadic or inherited fatal neurodegenerative conditions.They selectively affect the upper and/or lower motor neurons in the brain and spinal cord and feature a slow onset and a subacute course contingent upon the site of damage.The main types include amyotrophic lateral sclerosis,progressive muscular atrophy,primary lateral sclerosis,and progressive bulbar palsy,the pathological processes of which are largely identical,with the main disparity lying in the location of the lesions.Amyotrophic lateral sclerosis is the representative condition in this group of diseases,while other types are its variants.Hence,this article mainly focuses on the advancements and challenges in drug research for amyotrophic lateral sclerosis but also briefly addresses several other important degenerative motor neuron diseases.Although the precise pathogenesis remains elusive,recent advancements have shed light on various theories,including gene mutation,excitatory amino acid toxicity,autoimmunology,and neurotrophic factors.The US Food and Drug Administration has approved four drugs for use in delaying the progression of amyotrophic lateral sclerosis:riluzole,edaravone,AMX0035,and tofersen,with the latter being the most recent to receive approval.However,following several phaseⅢtrials that failed to yield favorable outcomes,AMX0035 has been voluntarily withdrawn from both the US and Canadian markets.This article presents a comprehensive summary of drug trials primarily completed between January 1,2023,and June 30,2024,based on data sourced from clinicaltrials.gov.Among these trials,five are currently in phaseⅠ,seventeen are in phaseⅡ,and eleven are undergoing phaseⅢevaluation.Notably,24 clinical trials are now investigating potential disease-modifying therapy drugs,accounting for the majority of the drugs included in this review.Some promising drugs being investigated in preclinical studies,such as ATH-1105,are included in our analysis,and another review in frontiers in gene therapy and immunotherapy has demonstrated their therapeutic potential for motor neuron diseases.This article was written to be an overview of research trends and treatment prospects related to motor neuron disease drugs,with the aim of highlighting the latest potentialities for clinical therapy. 展开更多

目前缝洞型碳酸盐岩油藏PD储量评估主要以开发单元或者油气田为评估单元进行上市储量评估,评估方法通常采用递减法。由于缝洞型碳酸盐岩储层非均质性极强、连通性差、油气分布复杂和天然能量不足的特征,钻遇不同储层类型及不同断裂带类... 目前缝洞型碳酸盐岩油藏PD储量评估主要以开发单元或者油气田为评估单元进行上市储量评估,评估方法通常采用递减法。由于缝洞型碳酸盐岩储层非均质性极强、连通性差、油气分布复杂和天然能量不足的特征,钻遇不同储层类型及不同断裂带类型上单井的递减规律、产能差异性明显;后期需要人工补能开发,开发方式影响导致递减规律性不强,油藏产能波动大,评估合理初始点和递减率取值难度大。根据上市储量评估保守原则,综合调整阶段,评估单元划分过大导致递减率取值偏大,初始值取值偏低,造成当前储量评估结果与开发形势存在一定的矛盾,油气田或者开发单元储采比偏低,不能反映出油藏真实开发规律。针对这一问题,在突出断裂性质、储层特征、开发方式、水体能量及经济性等因素基础上,提出储量评估单元划分技术思路。首先精细划分油藏单元,然后重构相似特征油藏单元组合成不同评估单元进行上市储量评估,再结合其开发规律选择合理的初始点和递减率对不同评估单元上市储量进行评估,靠实缝洞型碳酸盐岩油藏上市储量。研究结果表明:以哈拉哈塘为例,储量评估单元优化前,PD储量为115.55×10^(4)t,储采比为3.03;优化后,PD储量为175.69×10^(4)t,储采比为4.59。优化后精细评估的产量预测结果更能反映出哈拉哈塘油田缝洞型碳酸盐岩油藏真实开发规律,与实际产量变化趋势更吻合,储量评估结果与储采比也更靠实。该方法将用来指导缝洞型碳酸盐岩油藏PD储量评估。 展开更多
