Abstract

The embryos of maize (Zea mays L.) inbred lines GS02, GS07, GS08, GS11 and GS15 were used as receptor materials to optimize the receptor system from the aspects of genotype, medium components and stress (PEG6000, mannitol, salt and low phosphorus). The results showed that GS07 had the highest induction rate (95.2%). Orthogonal test analysis showed that the best combination of medium components in induction was A₂B₃C₁D₃₍₂₎, namely, the concentration of 2, 4-dichlorophenoxy acetic acid (2,4-D) was 4 mg·mL^-1, the concentration of L-Proline (L-Pro) was 0.8 mg·mL^-1, and the concentration of silver nitrate (AgNO₃) was 10 mg·mL^-1 (or 5 mg·mL).

Abstract The endoplasmic reticulum (ER) is the site of entry of all proteins that function in the secretory pathway including the extracellular environment. Because it controls the folding of newly synthesized secretory proteins, the ER is indispensable for the maintenance of proteostasis in the secretory pathway. Within the ER and, in part, in post-ER compartments, the quality control of protein folding is under the regulation of the unfolded protein response (UPR) pathways. The UPR strategy is to enhance protein folding, increase the ER degradation pathway of misfolded proteins, and allow the exit from the ER of More >

Abstract Seedlings of Taxus chinensis var. mairei were used as experimental materials to study the adaptation of Piriformospora indica to this plant under water stress. The materials were divided into two groups, namely, with or without inoculation with P. indica. Each group was subjected to four different levels of water stress. Vitality and physiological and biochemical indexes of the roots of T. chinensis var. mairei were regularly measured. Under water stress, T. chinensis var. mairei had significantly decreased root vitality; root vitality was higher in inoculated roots than in uninoculated roots. Under intense water stress, the inoculated roots had a higher soluble sugar… More >

Abstract Drought susceptibility and low genetic variability are the major constraints of lentil (Lens culinaris Medik.) production worldwide. Development of an efficient pre-field drought phenotyping technique and identification of diversified drought tolerant lentil genotype(s) are therefore vital and necessary. Two separate experiments were conducted using thirty diverse lentil genotypes to isolate drought tolerant genotype(s) as well as to assess their diversity. In both of the experiments, significant (p ≤ 0.01) variation in genotype (G), treatment (T) and G X T was observed for most of the studied traits. In experiment I, genotypes were examined for drought tolerance at… More >

Abstract Water is essential for the growth period of crops; however, water unavailability badly affects the growth and physiological attributes of crops, which considerably reduced the yield and yield components in crops. Therefore, a pot experiment was conducted to investigate the effect of foliar phosphorus (P) on morphological, gas exchange, biochemical traits, and phosphorus use efficiency (PUE) of maize (Zea mays L.) hybrids grown under normal as well as water deficit situations at the Department of Agronomy, University of Agriculture Faisalabad, Pakistan in 2014. Two different treatments (control and P @ 8 kg ha⁻¹ ) and four hybrids… More >

Abstract As a natural analog of resveratrol, piceatannol (Pic) exhibits good antioxidant and anti-inflammatory activities in different disease models. However, the role of Pic in type 1 diabetes mouse model has not been reported yet. In this study, we investigated the in vivo effect of Pic in streptozotocin (STZ)-induced type 1 diabetic mice. Mice were injected with STZ to establish the type 1 diabetes mellitus (T1DM) model. After stable hyperglycemia was achieved, mice were then orally treated with Pic (40 mg/kg b.w., i.g.) for 30 days. The results indicated that Pic supplementation efficiently alleviated the typical symptoms… More >

Abstract Camelina (Camelina sativa L.) is famous for its oil quality and unique fatty acid pattern. Growth and yield of crops reduced under water deficit conditions. Environmental threat such as drought or water deficit condition is the emerging problem which creates the negative impact on the growth of plants. Based upon the current situation a pot study was performed in rain out-shelter to explore the effect of different plant densities (15, 10 and 5 plants per pot) on growth and seed yield of two camelina genotypes under normal (100% WHC) and water deficit (60% WHC) conditions by… More >

Abstract The endoplasmic reticulum (ER) is an organelle in the cell where proteins are created and folded. Folding is a very elaborate process that is often interrupted by various biotic and abiotic stresses, leading to the formation of unfolded and misfolded proteins called ER stress. Dithiothreitol (DTT)-induced unfolded protein response (UPR) in endoplasmic reticulum (ER) has been recently reported in plants. Also, previous studies demonstrated that treatment with polyethylene glycol (PEG₆₀₀₀) could stimulate water deficit in crops. However, further researches should be conducted to elucidate the molecular mechanism of ER stress response and the relationship between water… More >

Abstract In semiarid regions rainfall is often scarce and erratic in space and time, making valuable the exploration of news genotypes with superior behavior in dry land systems. Tricepiro (X Triticosecale Wittmack x X Agrotriticum Ciferri & Giacom) is a synthetic cereal with long cycle and high biomass production in semiarid environments. However its performance under controlled water stress has not yet been evaluated. The aim of this work was to investigate the effect of water stress on tricepiro genotypes in comparison with their progenitors: triticale and trigopiro. Morphophysiological traits related to forage yield were evaluated in the… More >

Abstract The aim of this study was to determine the efficiency of drought classification criteria that we previously reported for our grain sorghum genotypes. Two tolerant genotypes of grain sorghum [Sorghum bicolor (L.) Moench] (UAT-124 and UAT-152) and one susceptible (UAT-30) were subjected to drought under greenhouse conditions at either panicle initiation, flag leaf, or flowering. Results showed that the effects of drought depended on when drought stress occurred during development. Biomass of the three sorghum genotypes was significantly reduced at the flag leaf stage (48%) by drought stress, but the greatest reduction occurred in the susceptible… More >
