Abstract
Lipids are a principal component of plasma membrane, acting as a protective barrier between the cell and its surroundings. Abiotic stresses such as drought and temperature induce various lipid-dependent signaling responses, and the membrane lipids respond differently to environmental challenges. Recent studies have revealed that lipids serve as signal mediators forreducing stress responses in plant cells and activating defense systems. Signaling lipids, such as phosphatidic acid, phosphoinositides, sphingolipids, lysophospholipids, oxylipins, and N-acylethanolamines, are generated in response to stress. Membrane lipids are essential for maintaining the lamellar stack of chloroplasts and stabilizing chloroplast membranes under stress. However, the effects of lipid signaling targets in plants are not fully understood. This review focuses on the synthesis of various signaling lipids and their roles in abiotic stress tolerance responses, providing an essential perspective for further investigation into the interactions between plant lipids and abiotic stress.

Afreen T, Singh V, Yadav VK, Singh RP, Singh H. Impact of rainfall variability on the ecophysiology of Hyptis suaveolens: a study in the constructed tropical grassland. ENVIRONMENTAL MONITORING AND ASSESSMENT 2020; 192:388. [PMID: 32440902 DOI: 10.1007/s10661-020-08340-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2019] [Accepted: 05/04/2020] [Indexed: 06/11/2023]
Abstract
Hyptis suaveolens is considered one of the most potent invaders in the eastern part of Uttar Pradesh, India. Climate change especially precipitation variability along with invasion has enormous consequences. To understand how an invasive plant (H. suaveolens) performs and interacts with precipitation variability, particularly in tropical monsoon climate, is vital. To assess the above, three rainout shelters with simulated rainfall of 1600 mm (60% more rainfall than ambient), 1100 mm (average rainfall) and 800 mm (20% less rainfall than ambient) along with one unsheltered plot (open C) were established. Three invaded grassland (IG) and three uninvaded grasslands (NIG) patches of 1 × 1 m2 size were established randomly in each sheltered and unsheltered plot. Among the studied physiological properties and growth measurements, photosynthetic rate, height, diameter and biomass varied significantly with precipitation, in general, the maximum value of these in plots receiving maximum precipitation. Also, the aboveground biomass of H. suaveolens was found to be more sensitive towards precipitation treatment than belowground biomass. H. suaveolens biomass was linearly related to soil moisture (R2 = 0.73), and a linear combination of SM and soil pH increased the R2 value by 19%. The results indicate that H. suaveolens mediates certain soil properties especially related to N-mineralisation, to maintain a constant supply of nutrient, for faster growth under the favourable condition of enhanced precipitation. These findings suggest that the population of H. suaveolens has not evolved drought tolerance, so it is likely that H. suaveolens will not spread in the part of the world which is drier either naturally or due to climate change.

Abstract
Banana is a non- model crop plant, and one of the most important crops in the tropics and sub tropics. Heat stress is the major abiotic stress affecting banana crop production because of its long growth period and is likely to become a threat due to global warming. To understand an acquired thermotolerance phenomenon at the molecular level, the RNA-seq approach was employed by adapting TIR method. A total of 136.38 million high quality reads were assembled. Differentially expressed genes under induction (I) was 3936, I + L was 2268 and lethal stress was 907 compared to control. Gene ontology and DGE analysis showed that genes related to heat shock factors, heat shock proteins, stress associated proteins, ROS scavenging, fatty acid metabolism, protein modification were significantly up regulated during induction, thus preparing the organism or tissue at molecular and cellular level for acquired thermotolerance. KEGG pathway analysis revealed the significant enrichment of pathways involved in protein processing, MAPK signaling and HSPs which indicates that these processes are conserved and involved in thermo tolerance. Thus, this study provides insights into the acquired thermotolerance phenomena in plants especially banana.

Abstract
Plants respond to cold stress by modulating biochemical pathways and array of molecular events. Plant morphology is also affected by the onset of cold conditions culminating at repression in growth as well as yield reduction. As a preventive measure, cascades of complex signal transduction pathways are employed that permit plants to endure freezing or chilling periods. The signaling pathways and related events are regulated by the plant hormonal activity. Recent investigations have provided a prospective understanding about plant response to cold stress by means of developmental pathways e.g., moderate growth involved in cold tolerance. Cold acclimation assays and bioinformatics analyses have revealed the role of potential transcription factors and expression of genes like CBF, COR in response to low temperature stress. Capsella bursa-pastoris is a considerable model plant system for evolutionary and developmental studies. On different occasions it has been proved that C. bursa-pastoris is more capable of tolerating cold than A. thaliana. But, the mechanism for enhanced low or freezing temperature tolerance is still not clear and demands intensive research. Additionally, identification and validation of cold responsive genes in this candidate plant species is imperative for plant stress physiology and molecular breeding studies to improve cold tolerance in crops. We have analyzed the role of different genes and hormones in regulating plant cold resistance with special reference to C. bursa-pastoris. Review of collected data displays potential ability of Capsella as model plant for improvement in cold stress regulation. Information is summarized on cold stress signaling by hormonal control which highlights the substantial achievements and designate gaps that still happen in our understanding.

Abstract
Global warming is predicted to have a general negative effect on plant growth due to the damaging effect of high temperatures on plant development. The increasing threat of climatological extremes including very high temperatures might lead to catastrophic loss of crop productivity and result in wide spread famine. In this review, we assess the impact of global climate change on the agricultural crop production. There is a differential effect of climate change both in terms of geographic location and the crops that will likely show the most extreme reductions in yield as a result of expected extreme fluctuations in temperature and global warming in general. High temperature stress has a wide range of effects on plants in terms of physiology, biochemistry and gene regulation pathways. However, strategies exist to crop improvement for heat stress tolerance. In this review, we present recent advances of research on all these levels of investigation and focus on potential leads that may help to understand more fully the mechanisms that make plants tolerant or susceptible to heat stress. Finally, we review possible procedures and methods which could lead to the generation of new varieties with sustainable yield production, in a world likely to be challenged both by increasing population, higher average temperatures and larger temperature fluctuations.

Abstract
Plant productivity is greatly affected by environmental stresses such as drought, salt, and freezing. We previously described a C-repeat binding transcription factor from maize (ZmCBF3) that was upregulated by both abscisic acid and low-temperature and actively expressed during embryogenesis. To understand the stress response in rice, transgenic ZmCBF3 rice with ubiquitin promoter was developed. T3 generation was planted and analyzed. The results showed that overexpression of ZmCBF3 in rice did not cause growth retardation under normal growth conditions with improved tolerance to drought, high-salt, and low-temperature stresses. Moreover, the transgenic rice grain yield was similar to wild type plants under normal conditions. The transgenic plants showed enhanced survival rate and reduced malondialdehyde content and relative conductivity under drought, salt, and low-temperature stresses. ZmCBF3 overexpression in transgenic rice increased the transcript levels of stress-induced genes and enhanced the tolerance to drought, salt, and low-temperature stresses.

Abstract
Plants under low temperature (LT) stress exhibit a C-repeat binding factor (CBF)-dependent responsive pathway. The transcription factors in the CBF family, existing in multiple plant species, are the key regulators of the cold-responsive (COR) genes. CBF1 and CBF3 are regulated in a different way from CBF2, and CBF4 is the only known CBF gene definitely involved in abscisic acid (ABA)-dependent signaling pathways. RAP2.1 and RAP2.6 are the downstream regulators under CBFs. The upstream regulators of the CBF named inducer of CBF expression (ICE) acts as a positive regulator of CBFs. Meanwhile, these CBF signaling pathway components could associate with many other transcription activators and repressors in regulating gene expression when plants are under LT stress. HOS1 negatively regulates ICE1, which down regulates MYB15, an upstream repressor of CBFs. ZAT12 participates in the repression of CBFs, while ZAT10 and FRY2 negatively regulate the CBF-target genes. ADF5 was recently also found to repress CBFs. LOS2 works against ZAT10, and LOS4 positively regulates CBFs. SFR6 is involved in the modification of CBFs to activate the COR genes, and SIZ1-dependent sumoylation plays a positive role in the regulation of ICE1. The utilization of CBF-dependent signaling components has a broad perspective in the field of plant breeding for enhancing crop LT tolerance.

Abstract
C-repeat binding proteins (CBFs) are a group of transcription factors that have been proven to be important for stress tolerance in plants. Many of these transcription factors transactivate the promoters of cold-regulated genes via binding to low temperature- or dehydration-responsive cis-elements, thus conferring plants cold acclimation. In the present study, we isolated a C-repeat binding transcription factor from maize using the yeast one-hybrid system with the C-repeat motif from the promoter of the Arabidopsis COR15a gene as bait. The isolated transcription factor is highly similar to the Arabidopsis CBF3 in their predicted amino acid sequences, and is therefore designated ZmCBF3. Point mutation analyses of the ZmCBF3-binding cis-element revealed (A/G)(C/T)CGAC as the core binding sequence. Expression analyses showed that ZmCBF3 was upregulated by both abscisic acid and low temperature, and was actively expressed during embryogenesis, suggesting that ZmCBF3 plays a role in stress response in maize.

Abstract
The dehydration-responsive element binding proteins (DREB1)/C-repeat (CRT) binding factors (CBF) function as transcription factors and bind to the DRE/CRT cis-acting element (core motif: G/ACCGAC) commonly present in cold-regulated (COR) genes and subsequently upregulate the expression of such genes in Arabidopsis. We identified a DREB1A/CBF3-like gene, designated LpCBF3, from perennial ryegrass (Lolium perenne L.) by using RT-PCR and RACE (rapid amplification of cDNA end). The LpCBF3 gene contains all the conserved domains known to exist in other CBF genes. A comprehensive phylogenetic analysis using known and computationally identified CBF homologs in this study revealed that all monocot CBF genes are separately clustered from eudicot CBF genes and the LpCBF3 is the ortholog of rice OsDREB1A/CBF3 gene. Similar to other DREB1A/CBF3 homologs, expression of the LpCBF3 is induced by cold stress, but not by abscisic acid (ABA), drought, or salinity. Overexpression of the LpCBF3 cDNA in Arabidopsis induced expression of the Arabidopsis DREB1A/CBF3 target COR genes, COR15a and RD29A, without cold acclimation. Ion leakage in leaves of the overexpression transgenic plants was significantly reduced, an indication of enhanced freezing tolerance. Our data demonstrated that LpCBF3 not only resembles DREB/CBF genes of Arabidopsis, but is also capable of functioning as a transcriptional regulator in Arabidopsis, a species distant to the grass family.
