Validation of SSR markers for identification of high-yielding and Phytophthora Capsici root rot resistant chilli genotypes.

The study was designed to validate the previously reported 34 SSR markers using 78 chilli genotypes to detect significant trait specific markers as well as superior genotypes resistant to Phytophthora capsici root rot (PcRR). In this context, the identification of germplasm with higher yield per plant (YPP) leads to hype in stress tolerance index (STI) in genotypes, Chakwal3 (11.98), Greenfire (10.

Developing a simple and efficient modeling solution for predicting key phenological stages of table grapes in a non-traditional viticulture zone in south Asia.

Phenological shifts are one of the most visible signs of climatic variability and change in the biosphere. However, modeling plant phenological responses has always been a key challenge due to climatic variability and plant adaptation. Grapevine is a phenologically sensitive crop and, thus, its developmental stages are affected by the increase in temperature.

Exploring the effects of seasonal temperature variability on berry ripening and quality attributes in different viticulture regions may help in sustainable viticulture industry. The present research was designed to explore the effect of temperature variables on key quality attributes of table grape cultivars in Pothwar region of Pakistan.

Seasonal variability in the effect of temperature on key phenological stages of four table grapes cultivars.

Progressive warming of the grape growing regions has reduced the land capability for sustainable grapevine production and the geographical distribution of grapes. Bud burst, blooming, berry set, veraison, and harvest are the key phenological stages of grapevine, and are crucial for managing vineyard activities. The objective of this study was to evaluate the effect of seasonal temperature variability on the timing of key phenological stages of table grape cultivars in a new emerging viticulture region, i.

Association mapping for abiotic stress tolerance using heat- and drought-related syntenic markers in okra.

Background: Considerable production losses are caused by heat and drought stress in okra. Germplasm evaluation at genetic level is essential for the selection of promising genotypes. Lack of genomic information of okra limits the use of genetic markers.

Adsorption efficiency of date palm based activated carbon-alginate membrane for methylene blue.

In the current study, activated carbon (AC) was prepared from date palm using single step activation using boric acid as an activating agent. The synthesized AC was incorporated with alginate (AC-alginate (AC-alg)) to prepare membrane for adsorption of methylene blue (MB) in batch adsorption study. The prepared membrane was characterized using different types of analytical techniques such as FTIR, SEM, and TGA analysis.

Climate variables effect on fruiting pattern of Kinnow mandarin (Citrus nobilis Lour × C. deliciosa Tenora) grown at different agro-climatic regions.

Kinnow orchards grown in different agro-ecological regions of Punjab, Pakistan, namely Sargodha, Toba Tek Singh (TTS) and Vehari districts, were selected to assess the effect of climate variables on fruit-bearing patterns. Experiment was laid out in RCBD while selecting identical features Kinnow plants and labeled twigs at analogous canopy positions in all three sites. Temperature was reported higher in TTS and Vehari areas, while relative humidity in Sargodha accounted for different levels of agrometeorological indices by computing more variations in warm districts.

Biochar promotes soil organic carbon sequestration and reduces net global warming potential in apple orchard: A two-year study in the Loess Plateau of China.

The Loess Plateau is China's primary apple-growing area, and the orchard is a significant source of greenhouse gases (GHGs) emissions due to high nitrogen fertilizer input. Thus, a two-year field study was carried out to investigate the effects of apple wood derived biochar on GHGs emissions during apple orchard production, including soil organic carbon sequestration (SOCSR) and net global warming potential (NGWP) assessments. There are four treatments in this study: 20 t ha biochar in a non-fertilized plot (B); no biochar in a fertilized plot (F); 20 t ha biochar in a fertilized plot (FB); no biochar in a non-fertilized plot (CK).

Phylogenetic and expression dynamics of tomato ClpB/Hsp100 gene under heat stress.

Heat shock proteins (Hsps) are stress-responsive molecular chaperones, which uphold proper protein folding in response to external and internal stresses. The Hsp100 gene family plays a substantial role in thermos-tolerance of plants. This study investigated evolutionary relationship and expression of ClpB/Hsp100 gene family in tomato under heat stress.

Quantitative Inheritance of Sclerotinia Stem Rot Resistance in and Relationship to Cotyledon and Leaf Resistances.

is a necrotrophic fungus causing devastating stem rot and associated yield losses of canola/rapeseed () worldwide, including in Australia. Developing host resistance against Sclerotinia stem rot is critical if this disease in canola/rapeseed is to be successfully managed, as cultural or chemical control options provide only partial or sporadic control. Three breeding populations, C2, C5 and C6, including the parents, F, F, BCP1, and BCP2, were used in a field study with an objective of exploring the inheritance pattern of disease resistance (based on stem lesion length [SLL]) and the genetic relationships of disease with stem diameter (SD) or days to first flowering (DTF), and to compare these new adult plant stem resistances against with those of seedling (cotyledon and leaf) resistances in earlier studies.

Effect of Drought Stress on Capsaicin and Antioxidant Contents in Pepper Genotypes at Reproductive Stage.

Pepper is one of the most important vegetables and spices in the world. Principal pungency is contributed by secondary metabolites called capsaicinoids, mainly synthesized in the placenta of pepper fruit. Various factors, including drought, limit pepper production.

Biological evaluation of some important medicinal plants from Poonch valley, Azad Kashmir, Pakistan.

Objective: To estimate the phytochemical composition, antioxidant, antifungal, cytotoxic and phytotoxic activities of three important medicinal plants of Poonch valley, Azad Kashmir Pakistan.

Methods: Phytochemicals were investigated for both qualitative (phenols, flavonoids, alkaloids and saponins) and quantitative (total phenolic and flavonoid contents) analysis of plant extracts prepared in ethanol, ethyl acetate and benzene. Moreover, antioxidant potential was investigated by screening botanical extracts against 2, 2-diphenyl-1-picrylhydrazyl scavenging assay, phosphomolybdenum and total reducing power assay.

Examining foreign direct investment and environmental pollution linkage in Asia.

This study investigated the causal linkage between environmental pollution by carbon dioxide (CO) emissions and net foreign direct investment (FDI), along with some other variables, namely economic growth by real per capita income and trade openness, using balanced annual data of 17 countries from Asia for the period from 1980 to 2014. Panel cointegration tests confirm the long-run association among the variables. After checking the panel data for stationarity properties, the method panel fully modified ordinary least squares (FMOLS) is implemented.

Age-related variations in the bactericidal activity of human sera against .

The human serum is a vital component of the innate immunity of the host that acts as the first line of defence against invading pathogens. A key player in serum-mediated innate immune defence is a system of more than 35 proteins, collectively named as the complement system. After exposure of the pathogen, these proteins are activated in a cascade manner, ultimately forming a membrane attack complex (MAC) on the surface of the pathogen that directly lyses the bacterial cell.
