“…It affects the production of both rain-fed and irrigated crops. As plants are sessile in nature, they respond to drought stress in a series of processes at physiological, biochemical and molecular level, allowing them to escape or adapt to unfavorable conditions [4,5]. Furthermore, drought impairs nutrient uptake and transport, inhibits photosynthesis, loss of cell turgidity and accumulation of reactive oxygen species, crop growth and productivity and in extreme cases crop failure [6,7].…”

Drought stress is one of the main factors limiting crop production, which provokes a number of changes in plants at physiological, anatomical, biochemical and molecular level. To unravel the various mechanisms underpinning tobacco (Nicotiana tabacum L.) drought stress tolerance, we conducted a comprehensive physiological, anatomical, biochemical and transcriptome analyses of three tobacco cultivars (i.e., HongHuaDaJinYuan (H), NC55 (N) and Yun Yan-100 (Y)) seedlings that had been exposed to drought stress. As a result, H maintained higher growth in term of less reduction in plant fresh weight, dry weight and chlorophyll content as compared with N and Y. Anatomical studies unveiled that drought stress had little effect on H by maintaining proper leaf anatomy while there were significant changes in the leaf anatomy of N and Y. Similarly, H among the three varieties was the least affected variety under drought stress, with more proline content accumulation and a powerful antioxidant defense system, which mitigates the negative impacts of reactive oxygen species. The transcriptomic analysis showed that the differential genes expression between HongHuaDaJinYuan, NC55 and Yun Yan-100 were enriched in the functions of plant hormone signal transduction, starch and sucrose metabolism, and arginine and proline metabolism. Compared to N and Y, the differentially expressed genes of H displayed enhanced expression in the corresponding pathways under drought stress. Together, our findings offer insights that H was more tolerant than the other two varieties, as evidenced at physiological, biochemical, anatomical and molecular level. These findings can help us to enhance our understanding of the molecular mechanisms through the networks of various metabolic pathways mediating drought stress adaptation in tobacco.

“…Variation in the chlorophyll a fluorescence parameters and photosynthetic pigment levels of selected cultivars (Bio-902, CS-14, Pusa-Tarak and Laxmi) may be due to the intrinsic differences between the cultivars. It can be assumed from our results that the reduction in photosynthetic performance of all the cultivars is due to the damage of photosynthetic machinery (PSI and PSII) (Mittal et al 2012) or due to deviation of biochemical processes involving in PSII reaction centers or due to decline in the catalytic activity of Rubisco or due to inhibition of chlorophyll synthesis as it is a key component of photosynthesis in plants (Batra et al 2014;Haider et al 2018). The elevation in temperature also results in reduced maximal quantum yield (PSII) of plants (Hasanuzzaman et al 2013) such as tomato (Morales et al 2003), Populus (Ferreira et al 2006) and rice (Han et al 2009;Vani et al 2001).…”

“…However, APX has higher scavenging affinity for H 2 O 2 in comparison to CAT (Chalanika de silva and Asaeda 2017). A significant increase is observed in the activities of ROS enzymes (SOD, POD, CAT, GPX and APX) with respect to abiotic stress (Haider et al 2018;Vardharajulaet al 2011). In this study, each cultivar of Brassica juncea also showed a continuous rise in antioxidant activity.…”

In present study, the effects of combined Aluminium and Fluoride (AlF) stress on chlorophyll a fluorescence, photosynthetic pigments, antioxidant system and psb A gene expression are first time reported in four Brassica juncea cultivars (CS-14, Pusa-Tarak, Bio-902 and Laxmi). Each cultivar was exposed to soil supplemented with AlF (0, 50 + 25, 100 + 50 and 150 + 75 mgkg −1 ). Lowest decline in the chlorophyll content, saturating photosynthetically active photon flux density, maximum apparent electron transport rate and effective quantum yield (PSII) under AlF was observed in Pusa-Tarak followed by CS-14, Bio-902 and Laxmi. The improved performance of the cultivar Pusa-Tarak under AlF stress was accompanied by an increase in proline level and enzymes activity of catalase and ascorbate peroxidase. However, significant increase in superoxide dismutase activity was observed in cultivar Laxmi. We also observed that AlF inhibits psb A gene expression to a lesser extent in tolerant cultivar Pusa-Tarak in comparison to susceptible cultivar Laxmi.Abbreviations: Chl: chlorophyll; Car: carotenoids; PPFDsat: saturating photosynthetically active photon flux density of PSII; ΔF/Fm ′ sat: effective quantum yield of PSII at saturating PPFD; ETRmax: maximum electron transport rate; PSII: photosystem II ARTICLE HISTORY

“…According to Souza et al (2015), the ideal range for total N content in peach seedlings is from 509.94 to 617.24 (mg plant -1 ), which agrees with the present research. Perennial fruit species of the genus Prunus, such as the peach tree [Prunus persica L. (Basthc)], accumulate N in the form of free proteins or amino acids, as well as non-structural carbohydrates that include starch and soluble sugars (sucrose, glucose, fructose and sorbitol) (Haider et al, 2018). Such molecules play an essential role in vegetative growth, providing structural components for the formation of new cells and consequently maximum biomass production.…”

The aim of this study was to evaluate the efficiency of nutrient uptake, accumulation, distribution and use, and its relationship with growth variables, chlorophyll content, and root and shoot dry-weight partitioning in the ‘Okinawa Roxo’ peach rootstock, submitted to different nutrient solutions and substrates. The experimental design was completely randomised, with four treatments and five replications. The treatments were T1: Ns1 = Souza et al. nutrient solution (2011), applied to a sand substrate; T2: Ns2 = Hoagland and Arnon (1950), applied to a sand substrate; T3: Commercial Substrate + H2O; and T4: Control, Sand + H2O. Ninety days after transplanting (DAT), morphological, physiological and nutritional parameters were determined in the ‘Okinawa Roxo’ rootstock, together with the correlation between nitrogen concentration and nitrogen balance index, and the chlorophyll content and index. The greatest zinc content was detected in the shoots of the ‘Okinawa Roxo’ plants, at more than 80% of the accumulated total. Treatments T1 and T2 (nutrient solutions Ns1 and Ns2 respectively) made it possible to obtain ‘Okinawa Roxo’ plants with the best morphophysiological characteristics, being ready for grafting three months after transplanting in a greenhouse. The use of the Ns1 nutrient solution resulted in greater efficiency in the uptake and use of the nutrients nitrogen (N), potassium (K) and iron (Fe). The N and Total Chlorophyll concentrations in the leaves of the red-leaved peach tree can be estimated indirectly with a chlorophyll meter, and are an accurate indication of the nutritional status of the plant in relation to nitrogen content.
