    查看更多>>摘要：Receptor-like kinases (RLKs) and receptor-like cytoplasmic kinases (RLCKs) play an indispensable role in the perception and transmission of extracellular signals in plants.In rice,these kinases actively participate in immune responses against a variety of pathogens,including fungi,bacteria,and viruses.However,research on the specific response mechanisms and the spectrum of different kinase activities against various pathogens remains insufficient.This review provides an in-depth and comprehensive overview of the types and functions of RLKs and RLCKs involved in disease resistance,emphasizing the central role of certain RLKs and RLCKs in the plant immune system.These kinases can recognize specific molecular patterns of pathogens and rapidly initiate an immune response in rice.Furthermore,the activity and functional regulation of these key kinases are tightly controlled by various post-translational modifications,such as phosphorylation and ubiquitination.This meticulous regulation ensures that the rice immune system's response is both precise and timely,effectively balancing the intensity of the immune response and preventing potential issues caused by either hyperactivity or insufficiency.By synthesizing current research findings,this review not only broadens our understanding of the role of RLKs and RLCKs in plant immunity but also provides new perspectives and strategies for future research on disease resistance breeding in rice.Future studies are expected to delve deeper into the signaling networks and regulatory mechanisms of these kinases,exploring their potential in agricultural production to develop rice varieties with enhanced disease resistance.

    查看更多>>摘要：Lodging is more than just plants falling over;it incurs significant economic losses for farmers leading to a decrease in both yield and quality of the final produce.Human management practices,such as dense sowing,excessive nitrogen fertilizer applications,inappropriate sowing dates,and upland rice cultivation,exacerbate the risk of lodging in rice.While breeders have developed high-yielding rice varieties utilizing the sd1 gene,relying solely on this gene is insufficient to enhance lodging resistance.Identifying the traits that contribute to lodging resistance is crucial.Key factors include biochemical,anatomical,and morphological traits,such as the levels of lignin,cellulose,hemicellulose,silicon,and potassium,along with the number and area of vascular bundles and the thickness,diameter,and length of the culm.Moreover,markers associated with lodging-related genes,like SCM2,SCM3,SCM4,and prl4,can be utilized effectively in marker-assisted backcrossing to develop rice varieties with desirable culm traits.This literature review aims to aid rice breeders in addressing the issue of lodging by examining traits that influence lodging resistance,developing phenotyping strategies for these traits,identifying suitable instrumentation,exploring methods for screening lodging-resistant plants,understanding the mathematical relationships involved,and considering molecular breeding aspects for pyramiding genes related to lodging.

    查看更多>>摘要：Rice (Oryza sativa L.) is a major food crop in China,and its high and stable yield is crucial for ensuring food security in the country.However,over the past few years,extreme weather events induced by global climate change have impacted rice growth.For example,the effects of heat stress on rice quality and yield have been significant.Therefore,it is fundamental to conduct in-depth research on the heat-tolerance mechanisms of rice and to cultivate superior new thermotolerant rice varieties.This review summarizes the adverse effects of high temperatures on rice growth at various stages,the heat-tolerance mechanisms in rice,and the heat-tolerance genes and QTLs that have been identified in recent years.We also discuss strategies to enhance the heat tolerance of rice,offering new insights for rice breeding research.

    查看更多>>摘要：Histone acetylation is indispensable in the process of crops resisting abiotic stress,which is jointly catalyzed by histone acetyltransferases and deacetylases.However,the mechanism of regulating salt tolerance through histone acetyltransferase GCN5 is still unclear.We revealed that GCN5 can catalyze the acetylation of canonical H3 and H4 lysine residues both in vivo and in vitro in rice.The knockout mutants and RNA interference lines of OsGCN5 exhibited severe growth inhibition and defects in salt tolerance,while the over-expression of OsGCN5 enhanced the salt tolerance of rice seedlings,indicating that OsGCN5 positively regulated the response of rice to salt stress.RNA-seq analysis suggested OsGCN5 may positively regulate the salt tolerance of rice by inhibiting the expression of OsHKT2;1 or other salt-responsive genes.Taken together,our study indicated that GCN5 plays a key role in enhancing salt tolerance in rice.

    Molecular Evolution of Rice Blast Resistance Gene bsr-d1

    查看更多>>摘要：Rice blast,caused by the fungus Magnaporthe oryzae,reduces rice yields by 10％ to 35％.Incorporating blast resistance genes into breeding programs is an effective strategy to combat this disease.Understanding the genetic variants that confer resistance is crucial to this strategy.The gene Bsr-d1 encodes a C2H2-like transcription factor,and its recessive allele confers broad-spectrum resistance against infections by various strains of M.oryzae.In this study,we investigated the molecular evolution of the rice blast resistance gene bsr-d1 in a representative population consisting of 827 cultivated and wild rice accessions.Our results revealed that wild rice exhibited significantly higher nucleotide diversity,with polymorphic regions primarily concentrated in the promoter region,in contrast to indica and japonica rice varieties.The Bsr-d1 gene displayed significant differentiation between indica and japonica rice varieties,with the bsr-d1 resistance allele being unique to indica rice.Haplotype network and phylogenetic analyses suggested that the bsr-d1 resistance allele most likely originated from Oryza nivara in the region adjacent to the Indian Peninsula and the Indochina Peninsula.Moreover,we explored the utilization of bsr-d1 resistance alleles in China and designed a pair of DNA primers based on the polymorphic sites for the detection of the bsr-d1 resistance gene.In summary,our study uncovering the origin and evolution of bsr-d1 will enhance our understanding of resistance gene variation and expedite the resistance breeding process.

    查看更多>>摘要：Rice direct seeding technology is an appealing alternative to traditional transplanting because it conserves labor and irrigation resources.Nevertheless,there are two main issues,salt stress and alkaline stress,which contribute to poor emergence and seedling growth,thereby preventing the widespread adoption and application of this technique in the Ningxia Region of China.Therefore,to determine whether germination can be promoted by mixed-oligosaccharide (KP) priming (in which seeds are soaked in a KP solution before sowing) under salt and alkaline stress,a proteomics study was performed.KP-priming significantly mitigated abiotic stress,such as salt and alkaline stress,by inhibiting root elongation,ultimately improving seedling establishment.By comparing the proteomics analyses,we found that energy metabolic pathway was a vital factor in KP-priming,which explains the alleviation of salt and alkaline stress.Key proteins involved in starch mobilization,pyruvate mobilization,and ATP synthesis,were up-regulated by KP-priming,significantly blocking salt and alkaline-triggered starch accumulation while enhancing pyruvate metabolism.KP-priming also up-regulated ATP synthase to improve energy efficiency,thereby improving ATP production.In addition,it enhanced antioxidant enzymatic activities and reduced the accumulation of reactive oxygen species.All of these factors contributed to a better understanding of the energy regulatory pathway enhanced by KP-priming,which mediated the promotion of growth under salt and alkaline conditions.Thus,this study demonstrated that KP-priming can improve rice seed germination under salt and alkaline stress by altering energy metabolism.

    查看更多>>摘要：The Ground Cover Rice Production System (GCRPS) has considerable potential for securing rice production in hilly areas.However,its impact on yields and nitrogen (N) fates remains uncertain under varying rainfall conditions.A two-year field experiment (2021-2022) was conducted in Ziyang,Sichuan Province,located in the hilly areas of Southwest China.The experiment included two cultivation methods:conventional flooding paddy (Paddy,W1) and GCRPS (W2).These methods were combined with three N management practices:N1 (no-N fertilizer),N2 (135 kg/hm2 urea as a base fertilizer in both W1 and W2),and N3 (135 kg/hm2 urea with split application for W1 and 67.5 kg/hm2 urea and chicken manure separately for W2).The WHCNS (Soil Water Heat Carbon Nitrogen Simulator) model was calibrated and validated to simulate ponding water depth,soil water storage,soil mineral N content,leaf area index,aboveground dry matter,crop N uptake,and rice yield.Subsequently,this model was used to simulate the responses of rice yield and N fates to GCRPS under different types of precipitation years using meteorological data from 1980 to 2018.The results indicated that the WHCNS model performed well in simulating crop growth and N fates for both Paddy and GCRPS.Compared with Paddy,GCRPS reduced N leaching (35.1%-54.9%),ammonia volatilization (0.7%-13.6%),N runoff (71.1%-83.5%),denitrification (3.8%-6.7%),and total N loss (33.8%-56.9%) for all precipitation year types.However,GCRPS reduced crop N uptake and yield during wet years,while increasing crop N uptake and yield during dry and normal years.Fertilizer application reduced the stability and sustainability of rice yield in wet years,but increased the stability and sustainability of rice yield in dry and normal years.In conclusion,GCRPS is more suitable for normal and dry years in the study region,leading to increased rice yield and reduced N loss.
