Abstract
Wild marigold has a growing demand for its essential oil in the flavor and fragrance industries. It can be grown over a broad range of climates, but the changing climatic conditions lead to abiotic stresses, thus restricting its productivity. Abiotic stresses at elevated levels result in the reduction of germination, growth, and essential oil quality of wild marigold leading to heterogeneous and inferior grades of "Tagetes oil." Drought, salinity, and heavy metal stress at elevated levels have common effects in terms of ROS formation, which are the major cause of growth deterioration in wild marigold. Temperatures above 35°C inhibit seed germination. Irradiance stress reduces the biomass and essential oil yield. Waterlogging adversely affects the survival of wild marigold in high rainfall regions. The application of plant nutrients (fertilizers) modulates the biomass and essential oil yield. Wild marigold employs multiple tolerance mechanisms to cope up with the adverse effects of abiotic stresses such as the increased activity of antioxidants to maintain cellular redox homeostasis, enhanced lipid peroxidation in the cell membrane to maintain cell wall architecture, production of secondary metabolites, and accumulation of osmolytes. In this review, we tried to understand how abiotic stresses affect wild marigold. Understanding the physiological changes and biochemical characteristics of stress tolerance will contribute to the development of stress-tolerant lines of wild marigold.

Abstract
Salt stress impairs global agricultural crop production by reducing vegetative growth and yield. Despite this importance, a number of gaps exist in our knowledge about very early metabolic responses that ensue minutes after plants experience salt stress. Surprisingly, this early phase remains almost as a black box. Therefore, systematic studies focussing on very early plant physiological responses to salt stress (in this case NaCl) may enhance our understanding on strategies to develop crop plants with a better performance under saline conditions. In the present study, hydroponically grown Vicia faba L. plants were exposed to 90 min of NaCl stress, whereby every 15 min samples were taken for analyzing short-term physiologic responses. Gas chromatography-mass spectrometry-based metabolite profiles were analysed by calculating a principal component analysis followed by multiple contrast tests. Follow-up experiments were run to analyze downstream effects of the metabolic changes on the physiological level. The novelty of this study is the demonstration of complex stress-induced metabolic changes at the very beginning of a moderate salt stress in V. faba, information that are very scant for this early stage. This study reports for the first that the proline analogue trans-4-hydroxy-L-proline, known to inhibit cell elongation, was increasingly synthesized after NaCl-stress initiation. Leaf metabolites associated with the generation or scavenging of reactive oxygen species (ROS) were affected in leaves that showed a synchronized increase in ROS formation. A reduced glutamine synthetase activity indicated that disturbances in the nitrogen assimilation occur earlier than it was previously thought under salt stress.

Single nucleotide mutation in the barley acetohydroxy acid synthase (AHAS) gene confers resistance to imidazolinone herbicides. Proc Natl Acad Sci U S A 2011; 108:8909-13.

Abstract
Induced mutagenesis can be an effective way to increase variability in self-pollinated crops for a wide variety of agronomically important traits. Crop resistance to a given herbicide can be of practical value to control weeds with efficient chemical use. In some crops (for example, wheat, maize, and canola), resistance to imidazolinone herbicides (IMIs) has been introduced through mutation breeding and is extensively used commercially. However, this production system imposes plant-back restrictions on rotational crops because of herbicide residuals in the soil. In the case of barley, a preferred rotational crop after wheat, a period of 9-18 mo is required. Thus, introduction of barley varieties showing resistance to IMIs will provide greater flexibility as a rotational crop. The objective of the research reported was to identify resistance in barley for IMIs through induced mutagenesis. To achieve this objective, a sodium azide-treated M(2)/M(3) population of barley cultivar Bob was screened for resistance against acetohydroxy acid synthase (AHAS)-inhibiting herbicides. The phenotypic screening allowed identification of a mutant line showing resistance against IMIs. Molecular analysis identified a single-point mutation leading to a serine 653 to asparagine amino acid substitution in the herbicide-binding site of the barley AHAS gene. The transcription pattern of the AHAS gene in the mutant (Ser653Asn) and WT has been analyzed, and greater than fourfold difference in transcript abundance was observed. Phenotypic characteristics of the mutant line are promising and provide the base for the release of IMI-resistant barley cultivar(s).

Abstract
In four rice (Oryza sativa L.) mutants resistant to hydroxy-L-proline (Hyp), HYP101, HYP203, HYP205 and HYP210, and in their original variety, Nipponbare, free proline and Hyp contents in the seeds and in the 14-day-old seedlings have been determined. The four mutants can be divided into two groups: HYP101 and HYP203 are classified as to recessive gene and the levels of free proline are similar to that of the original variety; the second group includes mutants HYP205 and HYP210 where the Hyp resistance is transmitted heterozygously and, both in the seeds and in the seedlings, a remarkable increase in free proline content is observed. In particular, free proline contents in the seeds of HYP205 and HYP210 are, respectively, 24 and 12 times that of the original variety. Hyp is detected only in the seedlings cultured with Hyp solution. In the Hyp resistant seedlings of HYP205 and HYP210, Hyp contents are twice that of the original variety and less than half in the seedlings of HYP101 and HYP203. Hyp resistance and differential proline levels are also evident in the callus initiated from the mutants. This suggests that the Hyp resistant mutants are good genetic markers both in planta and in vitro. The Hyp mutants are also discussed with regard to stress resistance.

Abstract
Three rice (Oryza sativa L.) mutants resistant to hydroxy-L-proline (Hyp), HYP 101, HYP 202 and HYP 203, were selected from an ethylene imine mutagenized M2 population of the original variety, 'Nipponbare', and their biochemical and genetical characteristics were investigated. The sensitivity of the mutants to Hyp could be clearly differentiated from that of the original variety when seeds were germinated and cultured with 10(-4)∼10(-3) M Hyp for 10 days. A difference in Hyp sensitivity was also observed among the HYP mutant lines, HYP 101 being the most resistant line. When free amino acids in seeds and 15-day-old seedlings were analyzed, the composition of the amino acids in the mutants was somewhat different from that found in the original variety. However, free proline accumulation was not detected in either the HYP mutants or the original variety. In each mutant line, HYP resistance was transmitted with a single recessive nuclear gene (hpr). These results suggest that the mechanism of Hyp resistance controlled by the recessive gene do not involve free proline accumulation.

Abstract
A mutant line of barley, R(othamsted)-Pr 79/4, has been isolated which grows poorly in natural air, but normally in air enriched to 0.2% CO2. Analysis of the products of (14)CO2 fixation showed that there was no major block in photosynthetic or photorespiratory carbon metabolism in the mutant and that rates of CO2 fixation were only slightly lower than those measured in the wild type (c.v. Maris Mink). Leaves of the mutant line contained only 10% of the catalase (EC 1.11.1.6) activity found in the wild type; and the two major bands of catalase activity detected after starch-gel electrophoresis of extracts of normal leaves were missing from similar extracts of RPr 79/4. Peroxisomes isolated from mutant leaves contained negligible catalase activity, but normal levels of other enzymes involved in photorespiration. Genetic analysis has shown that the mutation is recessive and that both air-sensitivity and catalase-deficiency segregate together in F2 plants derived from a cross between the mutant and the cultivar Golden Promise. [1-(14)C]Glycollate was not converted to (14)CO2 faster in the mutant leaves than in the normal leaves. Thus there was no evidence that photorespiratory CO2 may be obtained by the chemical action of H2O2 on glyoxylate or hydroxypyruvate.

Abstract
Barley (Hordeum vulgare L.) mutants altered in the regulation of synthesis of aspartate-derived amino acids were sought by screening embryos for growth on a medium containing lysine plus threonine. One mutant, Rothamsted 2501, was selected with good growth. From the segregation of resistance in the following generations, it was concluded that the resistance was conferred by a dominant gene, Lt1. No homozygous Lt1/Lt1 fertile plants have been recovered. Partially purified aspartate kinase preparations from resistant and sensitive plants were separated on DEAE-cellulose chromatography into three peaks of activity (I, II, III) and the feedback regulatory properties of these peaks determined. These peaks are considered to be three isozymic forms of aspartate kinase, one predominantly sensitive to threonine and two sensitive to lysine or lysine plus S-adenosyl methionine. The feedback characteristics of one of the peaks of aspartate kinase activity from resistant plants were changed such that lysine was half-maximally inhibitory at 10 rather than 0.4 mM. Increases in te concentrations of the free pools of threonine (4x) and methionine (2x) were measured in young plants grown on a basal medium. Threonine in the soluble fraction of mature seeds from resistant plants was increased from 0.8 to 9.6% of the total threonine content. The total content of both threonine and methionine of the seeds was increased by 6% compared with grain of similar nitrogen content.
