Soil salinity is a major agricultural constraint in many countries. Plants’ response to salinity depends on the species and the salt concentration in the soil. The objective of this study was to test the resistance of three leguminous plants - common bean (variety ‘El-Jadida’), broad bean (variety ‘Claro de Luna’), and alfalfa (variety ‘Diamon’) - to several salinity rates and to show which one was more resistant to salt stress. This study was carried out under controlled conditions, with six NaCl concentrations (0, 1, 3, 6, and 9 g/kg) added to a mixture of potting soil and sand. A completely randomised design was used, where the three legumes were cultivated with different salt concentrations to determine the effect of these doses on fresh biomass, dry mass, and physiological parameters (sodium and proline content). The results showed the negative effect of salinity on fresh biomass and dry mass of shoots and roots. Claro de Luna, the broad bean variety, was more adapted to salinity than alfalfa and common bean. The amount of sodium in the shoots and roots of the three species increased with increasing salinity. Alfalfa may play a role in soil desalination; at 53.33 mM NaCl, 100 mg alfalfa dry mass absorbed 4.5 mg Na per pot, which corresponded to the uptake of about 0.6 kg Na per hectare of soil. Proline content increased with increasing salt concentrations.

Using open-top chamber technology, we investigated the foliar phenolic response of common bean (Phaseolus vulgaris L. cv. Bergamo) to a chronic, moderate ozone stress. Three atmospheric concentrations of ozone were tested: non-filtered air (NF) prevailing at the experimental site, and non-filtered air supplied with 40 (NF+40) and 60 nL L–1 ozone (NF+60), respectively. Both constitutive and ozone-induced non-polymerized phenolics were considered with regards to pollutant concentration, exposure time, leaf type (primary or trifoliate), and leaf growth. The biomass of primary leaves was unaffected by the tested ozone concentrations, whereas dry mass of first and second trifoliate leaves significantly decreased as atmospheric ozone increased. Characteristic symptoms were observed on the upper surface of leaves from the two ozone-supplied treatments. Their severity reflected both leaf exposure time and ozone concentration. As a whole, the total content of foliar soluble constitutive phenolics remained unchanged as the ozone increased, even for leaves almost totally covered with dark-brown discolourations. Nonetheless, among the three main detected phenolics, the accumulation of the kaempferol derivative could be significantly stimulated by ozone. Also, six ozone-induced phenolics could be synthesized by leaves exposed to the two pollutant-enriched atmospheres, and their elicitation and amount were closely connected with both exposure time and ozone concentration.

The Common

The common bean (Phaseolus vulgaris) is a major source of protein and essential nutrients for humans. To explore the genetic diversity and phylogenetic relationships of P. vulgaris, its complete mitochondrial genome (mitogenome) was sequenced and assembled. The mitogenome is 395,516 bp in length, including 31 unique protein-coding genes (PCGs), 15 transfer RNA (tRNA) genes, and 3 ribosomal RNA (rRNA) genes. Among the 31 PCGs, four genes (mttB, nad1, nad4L, and rps10) use ACG as initiation codons, which are altered to standard initiation codons by RNA editing. In addition, the termination codon CGA in the ccmFC gene is converted to UGA. Selective pressure analysis indicates that the ccmB, ccmFC, rps1, rps10, and rps14 genes were under evolutionary positive selection. The proportions of five amino acids (Phe, Leu, Pro, Arg, and Ser) in the whole amino acid profile of the proteins in each mitogenome can be used to distinguish angiosperms from gymnosperms. Phylogenetic analyses show that P. vulgaris is evolutionarily closer to the Glycininae than other leguminous plants. The results of the present study not only provide an important opportunity to conduct further genomic breeding studies in the common bean, they also provide valuable information for future evolutionary and molecular studies of leguminous plants.

ABSTRACT Macrophomina phaseolina is a soilborne pathogen with a wide range of hosts and its control through agricultural practices is difficult. The aim of this study was to quantify the severity of root rot (SRR) caused by M. phaseolina in common bean cultivars and its impact on yield components. The experiments were carried out under greenhouse conditions with the common bean cultivars ‘ANFC-9 Agro Norte’, ‘BRS Esteio’, ‘BRS Estilo’, ‘BRS Pérola’, ‘FTS Soberano’, ‘IPR Campos Gerais’, ‘IPR Tangará’, ‘IPR Tuiuiú’, ‘IPR Uirapurú’ and ‘TAA Dama’. Three isolates of M. phaseolina obtained from infected plants of common bean, soybeans and maize were inoculated in the common bean cultivars. In the phenological stage R9 of grain harvest maturity, the SRR and the yield components of root dry mass (RDM), number of pods per plant (NPP), number of grains per plant (NGP) and grain mass per plant (GMP) were assessed. All common bean cultivars were susceptible to M. phaseolina, showing a reduction in NPP, NGP and GMP. SPR was greater than 75%, regardless of the origin of isolates. Considering the average of cultivars, there was a significant decrease of 54.3% in RDM, compared to control treatments. The cultivars ‘IPR Tangará’, ‘ANFC-9 Agro Norte’, ‘BRS Esteio’, ‘BRS Pérola’ and ‘FTS Soberano’ had a decrease in at least one yield component, while a reduction occurred in all components for cultivar ‘IPR Tangará’. There was an average decrease in NPP, NGP and GMP of 7.9%, 7.6% and 7.2%; 13.4%, 12.8% and 6.7%; and 14.2%, 12.9% and 10.1%, considering the isolates obtained from beans, soybeans and maize, respectively.

The present study deals with the effects of stress due to varying concentrations of sodium chloride, cadmium, pH and exposure to pesticides on intracellular proline accumulation in Anabaena variabilis in laboratory conditions. The stresses induced due to these changes in their growth media were expressed as decrease in growth (by 40% at pH 5; 30% at 50 mM NaCl; 80% at 50 μM endosulphan and 55% at 10 μM CdSO4) as measured in terms of chlorophyll a concentrations in the test organism. Low pH (5, 6) had stronger negative effect on growththan increasing alkaline pH. The cyanobacterium showed varying degree of susceptibility to increasing salt, cadmium and endosulphan concentrations. Under all these altered conditions, their intracellular proline concentration was found to increase linearly in the test organism with increase in its amount of stress inducing substances in its vicinity. Proline appears to be a stress provoked substance in A. variabilis. However, there seemed to be a breakdown in the proline synthesis mechanism when concentrations of such compounds reached toxic proportions.

The dry and fresh biomass and metal concentration (Cr, Ni) in roots and shoots of mustard (S. alba L.) seedlings was evaluated in laboratory experiments with three types of washing waste-waters from cutlery production line. All tested washing waters reduced root dry mass, where-as the dry mass of shoots was either not affected or it increased. The effect of tested washing waters was stronger on fresh mass production than on dry mass production. This indicates problems in water reception and translocation. While the accumulation of Cr was higher in the roots, Ni was distributed equally through the whole plant seedling. Cr uptake in the roots and shoots was in average about 1.7 and 7.3 times, respectively, lower than that of Ni. Ni percentage uptake from washing waters in the roots and shoots was nearly equal and range from 10.2 to 15.8%.

Soils are known to differ in suppressiveness to soil-borne diseases, but the suppressiveness or otherwise to Fusarium wilt of Australian soils used to grow bananas is unknown. In this work we tested the relative suppressiveness of six key soil types. Banana (Musa (AAB group) ‘Pome’, cultivar ‘Lady Finger’) was grown in pots of the soils inoculated or not with Fusarium oxysporum f.sp. cubense (Foc) ‘Race 1’. Sixteen weeks after inoculation the plants were harvested and disease severity was assessed by measuring discoloration within the rhizome. In the inoculated pots, disease severity was greatest in the alluvial Liverpool and Virgil soils and least in the basaltic origin Tolga soil. No disease was detected in the non-inoculated pots. Soils with the lowest disease severity had the highest root mass, irrespective of inoculation, and the largest (negative) effect of inoculation on root dry mass. Disease severity in inoculated pots was negatively correlated with soil clay content and β-glucosidase activity. The results indicate that the risk of Fusarium wilt negatively impacting banana growth differs between soils of the main Australian banana-growing region.

Many plants accumulate high levels of free proline content (pro) and glycine betaine (GB) in response to abiotic stress, Pro and GB act as an osmoprotectant. Generally, these levels are high than those required to be used in protein synthesis. Salinity inhibition of plant growth is the result of osmotic and ionic effect and different plant species have developed different mechanisms to cope with those effects. In this study, accumulation of osmolytes of twenty tomato genotypes was evaluated in response to salinity stress. The seedlings of each genotype were divided into three groups, Sodium chloride (NaCl) dissolved in irrigation water to make variant concentration of 30 and 60 mg/L of salt concentration using electrical conductivity meter which were used to water the plants. Level of free proline and glycine betaine were measured. Data obtained were subjected to one way analysis of variance using SPSS (20) Statistical Software. Dry mass accumulation decreased with increased salt concentration in all the genotypes. However, the result differ significantly (P< 0.05). The highest dry mass accumulations at control were recorded on Tropimech and Giofranco F. with 6.00 and 5.97. The lowest dry mass accumulations were recorded on plant treated with 60mg/L of salt. Dangainakawa recorded the least accumulation of dry mass on plants treated with 60mg/l of salt with 0.90g followed by Dan Gombe with 1.47g respectively. The highest free proline content of 1.46 µmolg-1was recorded on Dan gainakawa at plant treated with 60 mg/L of NaCl. The lowest proline content was recorded at control on Giofranco F. with 0.17 µmolg-1The highest GB content in all the plants were recorded at plants treated with 60 mg/L. However, the highest GB content (1.67) among the 20 (P<0.05) were recorded at 60 mg/L in Rio Grande followed by Bahaushe with 1.50 µmolg-1. In conclusion, GB and Pro are osmoregulators produced by tomato in response to stress so as to alleviate the consequence effects of salt stress.

In this study the effect of different concentrations of leaf (LR) and corm residue (CR) of saffron on seedling growth of fenugreek (<em>Trigonella foenum-graecum </em>L.), chickpea (<em>Cicer arietinum </em>L.) and arugula (<em>Eruca sativa</em> Mill.) as three potential companion crops for saffron were investigated under greenhouse condition. The experimental treatments were four concentrations (0.5, 1.5, 3 and 6 %) together with no residue treatment of LR and CR were arranged in completely randomized design. Results showed that the highest emergence percentage of chickpea was obtained at LR concentration of 6 %. Chickpea shoot length and mass had an increasing trend with increase in concentrations of saffron CR. LR and CR of saffron only at concentration of 3 and 6 % reduced the emergence percentage and emergence rate of fenugreek, but all concentration of CR and LR had no negative effect on length and mass of shoot. Saffron residue imposed a slight inhibitory effect on emergence percent and emergence rate of arugula, while had it a positive effect on some seedling growth characters especially root dry mass. Hence, three tested crops can be recommended as potential candidates to be associated with the saffron, although, the growth response of selected plants was dose-dependent and somewhat different.
