Calcium(Ca^(2+))plays a pivotal role in various signal transduction pathways.Calcineurin B-like proteins(CBLs)are a unique group of Ca^(2+)sensors that decode Ca^(2+)signals by activating the plant specific protein kinase known as the CBL-interacting protein kinase(CIPK).In plants,the CBL-CIPK signaling network regulates multiple signals in response to different extracellular cues including abiotic stress.However,the genome wide annotation and expression patterns of CBLs and CIPKs in woody cutting flower plants are still unclear.In this study,a total number of 7 CBLs(RcCBLs)and 17 CIPKs(RcCIPKs)genes,divided into four and five subfamilies,respectively,were identified from the rose genome.All RcCBLs possess a classic elongation factor-hand(EF-hand)domain,while all RcCIPKs possess both the classic kinase and NAF domains.Most RcCBLs were predicted to be plasma membrane localized,whereas most RcCIPKs were predicted to be cytoplasmic localized.Synteny analysis showed that one RcCBL gene pair and five RcCIPK gene pairs have gone through whole genome duplication events.Promoter cis-element prediction assays indicated that RcCBLs and RcCIPKs could function in different abiotic stress responses in rose plants.Further quantitative real-time PCR analysis demonstrated that RcCBLs and RcCIPKs were expressed in different organs with overlapped but distinct patterns in response to various abiotic stresses.The findings in this work will provide fundamental information and gene resources for further functional research on RcCBLs and RcCIPKs.

Salinity is one of the major abiotic factors that limit the growth and productivity of plants.Foliar application of plant growth regulators(PGRs)may help plants ameliorate the negative impacts of salinity.Thus,a field experiment was conducted at the Botanical Garden University of Balochistan,Quetta,to explore the potential role of PGRs,i.e.,moringa leaf extract(MLE;10%),proline(PRO;1μM),salicylic acid(SA;250μM),and thiourea(TU;10 mM)in ameliorating the impacts of salinity(120 mM)on Plantago ovata,an important medicinal plant.Salinity hampered plant photosynthetic pigments and metabolites but elevated oxidative parameters.However,foliar application of PGRs enhanced photosynthetic pigments,including Chl b(21.11%),carotenoids(57.87%)except Chl a,activated the defense mechanisms by restoring and enhancing the metabolites,i.e.,soluble sugars(49.68%),soluble phenolics(33.34%),and proline(31.47%),significantly under salinity stress.Furthermore,foliar supplementation of PGRs under salt stress led to a decrease of about 43.02%and 43.27%in hydrogen peroxide and malondialdehyde content,respectively.Thus,PGRs can be recommended for improved photosynthetic efficiency and metabolite content that can help to get better yield under salt stress,with the best and most effective treatments being those of PRO and MLE to predominately ameliorate the harsh impacts of salinity.

One of the main reasons of the annual reduction in plant production all around the world is the occurrence of abiotic stresses as a result of an unpredicted changes in environmental conditions.abiotic stresses basically trigger numerous pathways related to oxygen free radicals’generation resulting in a higher rate of reactive oxygen species(ROS)production.Accordingly,higher rate of oxygen free radicals than its steady state causes to oxidize various types of molecules and compartments within the plants’cells and tissues.Oxidative stress is the result of high amount free radicals of oxygen interfering with different functions leading to undergo signiﬁcant changes from molecular to phenotypic levels.In response to oxidative stress,plants deploy different enzymatic and non-enzy-matic antioxidant mechanisms to detoxify extra free radicals and get back to a normal state.Applying some spe-ciﬁc treatments have shown to signiﬁcantly affect the antioxidant capacity and efﬁciency of the stressed cells and compartments.One of such reportedly effective treatments is the utilization of selenium(Se)element in stressed plants.Over the past years some different experiments evaluated the probable effect or efﬁciency of Se regarding its impact on plant under oxidative stress.Accordingly,based on the recent studies,Se has a signiﬁcant role in plant responses to abiotic stresses probably due to its ability to improve the plants’tolerance to oxidative stress.The signiﬁcant inﬂuences of Se,and its related components such as nano-selenium,in plants under oxidative stress rooting from abiotic stresses,along with the newﬁnding pertaining to its metabolism and translocation mechanisms inside the plant cells under oxidative stress condition are clearly explained in this review.However,there are still lack of a comprehensive explanation related to the precise mechanism of Se in plants under oxida-tive stress.

Indoleacetic acid(IAA)is an important regulator that plays a crucial role in plant growth and responses to abiotic stresses.In the present study,a sand cultivation experiment was carried out to investigate the effects of IAA at different concentrations(0,0.01,0.1,0.5,1,and 2.5 mmol/L)on maize growth,root morphology,mineral elements(Ca,Mg)and Cd uptake under 20 mg/kg Cd stress.The results showed that 0.01 mmol/L is the optimal IAA concentration for enhancing the Cd tolerance of maize.Compared with the control treatment,0.01 mmol/L IAA promoted maize growth,with significant increases in the height,shoot and root biomass by 34.6%,25.0%and 16.3%;altered the root morphology,with increases in root length,root tip number,and root tip density by 8.9%,31.4%and 20.7%,respectively;and enhanced the mineral element uptake of maize,resulting in signifi-cant increases in the Ca content in shoots and roots by 640.6%and 1036.4%and in the Mg content in shoots by 205.8%,respectively.In addition,0.01 mmol/L IAA decreased the Cd content and uptake in the shoots by 51.9%and 39.6%,respectively.Furthermore,the Cd content and uptake exhibited a significant negative correlation with Ca content in roots and a significantly positive correlation with root morphology,and the Cd content in shoots was significantly and negatively correlated with root tip number.Thus,0.01 mmol/L IAA was effective in enhancing the Cd tolerance and plant growth of maize.

As sessile organisms,plants possess a complex system to cope with environmental changes.Ca^(2+)functions as a vital second messenger in the stress signaling of plants,and the CBL-interacting protein kinases(CIPKs)serve as essential elements in the plant Ca^(2+)signaling pathway.In this study,calcineurin B-like protein-interacting protein kinase 26(BdCIPK26)from Brachypodium distachyon was characterized.Overexpression of BdCIPK26 enhanced tolerance to drought and salt stress of transgenic plants.Further investigations revealed that BdCIPK26 participated in abscisic acid(ABA)signaling,conferred hypersensitivity to exogenous ABA in transgenic plants,and promoted endogenous ABA biosynthesis.Moreover,BdCIPK26 was found to maintain ROS homeostasis in plants under stress conditions.Therefore,this study indicates that BdCIPK26 functions as a positive regulator in drought and salt stress response.

Waterlogging is an illustrious abiotic stress and the constrictions it enforces on plant roots have negative effects on growth and development.This study was undertaken to investigate waterlogging stress tolerant potential in chilli(Capsicum annum L.)genotypes through evaluating morphological,physiological,biochemical and anatomical parameters.Thirty-five days old seedlings of 10 chilli genotypes were exposed to waterlogging stress maintaining water height 3–5 cm over the soil surface artificially for three days.This duration(36–38 DAE)was termed as waterlogging period,and subsequent withdrawal of waterlogging condition(39–45 DAE)was regarded as a recovery phase.Based on their survival performance,two tolerant genotypes viz.,SRC-517 and BARI morich-2 and two susceptible genotypes viz.,AHM-206 and RI-1(6)were selected for studying stress tolerance mechanism.Under waterlogging,however,both genotypes(tolerant and susceptible)exhibited reduced root shoot length,dry weight ratio,petiole weight and leaf area,and noticeable reduction regarding these parameters was observed in susceptible genotypes.Moreover,tolerant genotypes displayed a higher recovery than susceptible genotypes after removal of waterlogging stress.Lower reduction of leaf area and photosynthetic pigments as well as higher reduction of relative water content(RWC)were noticed in susceptible genotypes.Higher accumulation of proline and total antioxidant capacity(TAC)during waterlogging condition in tolerant genotypes suggested lower oxidative damage.Although both genotypes lost total soluble sugar(TSS)relative to control at waterlogging stress,better performance was recorded in tolerant genotypes.During the period after the removal of extra water,a similar genotypic response in terms of TSS gain was seen.Undoubtedly,under flooding conditions,the development of aerenchyma cells in tolerant genotypes is a means of tolerance mechanism for long-term survival.Thus,the morpho-physiological and biochemical changes help to understand the tolerance mechanism in chi

Banana is a tropical crop cultivated in warm places.Chilling stress in Egypt is making banana crops less productive.Abscisic acid(ABA),a key plant hormone,regulates metabolic and physiological processes and protects plants from a variety of stresses.In vitro growing banana shoots were pre-treated with ABA at four concentrations(0,25,50,and 100 mM)and chilled at 5℃for 24 h,followed by a six-day recovery period at 25℃.By comparing ABA treatments to both positive and negative controls,physiological and biochemical changes were investigated.Chilling stress(5℃)caused a considerable increase in lipid peroxidation and ion leakage and reduced photosynthetic pigments in cold-treated plantlets.Increasing the concentration of ABA to 100μM enhanced the response to chilling stress.ABA had a major effect on mitigating chilling injury in banana shoots by keeping cell membranes stable and lowering the amount of ion leakage and lipid peroxidation.Also,ABA significantly maintained the photosynthetic pigment concentration of banana shoots;accumulated higher amounts of total soluble carbohydrates and proline;and increased DPPH radical scavenging activity.Furthermore,ABA treatment enhanced cold tolerance in chilling-stressed banana shoots through the regulation of antioxidant enzyme activity.Overall,the results show that ABA is a good choice for protecting banana shoots from the damage caused by chilling stress.

Drought stress is one of the most important abiotic stresses that plants face frequently in nature.Under drought conditions,many morphological,physiological,and molecular aspects of plants are changed and as a result plants experience a remarkable reduction in growth,yield,and reproduction.To expand our understanding of the molecular basis of the plant response to drought stress,the proteomic profile and protein-protein network of canola(Brassica napus L.)were studied.The focus was to show molecular mechanisms related to canola susceptibility to drought stress.The experiment used a completely randomized design,implemented in a hydroponic system under greenhouse conditions.To impose drought stress,plants were exposed to Hoagland’s solution supplemented with polyethylene glycol(PEG)6000 for 7 days.The drought stress resulted in 161reproducible protein spots in twodimensional electrophoresis of canola leaves.The t-student test showed 21 differentially abundant proteins(DAP),of which 2 and 19 were up and down accumulated,respectively.Two spots identified as 1-aminocyclopropane-1-carboxylate oxidase and D-2-hydroxyglutarate dehydrogenase showed an increased abundance of 2.11 and 1.77,respectively.The extended protein-protein interaction of differentially abundant proteins and KEGG analysis showed 47 pathways directly and indirectly associated with canola response to drought stress.DAPs with increased abundance were associated with amino acid and signaling processes,whereas DAPs with decreased abundance were mostly connected with pathways responsible for energy production.The results of the study will help to elucidate further the molecular events associated with the susceptibility to drought stress in canola.
