    (Friends Science Publ, 2020) Nazeer, Samreen; Basra, Shahzad M. A.; Iqbal, Shahid; Mateen, Ahmad; Hafeez, Muhammad Bilal; Akram, Muhammad Zubair; Zahra, Noreen
    Amaranth, being a nutrient-rich and climate resilient crop, can be a solution to improve nutritional quality and food security for increasing population. Aims of this study were to check the adaptability and yield potential of amaranth under semiarid climate conditions of Pakistan. This two-year field experiment was conducted at Directorate Research Area, University of Agriculture, Faisalabad. Germplasm of amaranth (ten genotypes) was imported from USDA and grown under semiarid environment to compare their phenology, leaf biochemical analysis and yield attributes in order to access its adaptability. Significant variations were observed among the genotypes for yield related attributes, leaf chlorophyll contents and phenology. Among genotypes, maximum grain yield was produced by PI 642733 followed by PI 619265, PI 636194 and Ames 15204. This was linked with stay green character (more leaf chlorophyll contents) of genotypes for longer period, as depicted by more seed setting periods of high yielder genotypes. Genotypes completed seed setting between 112 to 128 days after emergence. Furthermore, seed protein contents ranged between 11.73 to 19%. Genotypes PI 642733, PI 619265, PI 636194 and Ames 15204 were found promising and recommended to be grown in Rabi crop season in Faisalabad conditions. Huge diversity observed in the germplasm of amaranth which opened new avenues for the selection and production of suitable germplasm under different agro-ecological zones of Pakistan.

    (Life Sciences Soc Pakistan, 2021) Akram, Muhammad Zubair; Basra, Shahzad Maqsood Ahmed; Hafeez, Muhammad Bilal; Khan, Shahbaz; Nazeer, Samreen; Iqbal, Shahid; Saddiq, Muhammad Sohail
    Cultivation of quinoa, a climate-resilient and superfood crop, can be a viable option for food security than conventional food crops. A field experiment was conducted during growing season of 2018-2019 to evaluate 13 elite lines of quinoa. The data regarding stand establishment, phenology of developmental stages, root establishment, leaf biochemical, morphological attributes and seed viability were recorded and analysed. Seed yield was linked with phenological, physiological and morphological traits. Ten lines (4, 6, 9, 11, 15, 22, 24, 30, 45 and 126) seem to be high yielders than check that are originated from New Mexico and Peru. New line Q11 appears to be a high yielder among all the newly introduced lines and standard variety also. Q126 showed the maximum harvesting index. Standard variety UAFQ-7 seems to be higher in root length. Among lines, the duration of crops is also different. Q24 appears to be a short duration crop. Q15 and Q45 appear to be higher in anthocyanin and phenolic contents, respectively. Finding new germplasm having higher yield potential than the check variety will strengthen the popularity of new crops under the agro-climatic conditions of Faisalabad-Pakistan.

    Amaranth as Nutrition-Rich and Climatic Resilient Crop: A Review
    (University of Zagreb, Faculty of Mining, Geology and Petroleum Engineering, 2022) Nazeer, Samreen; Akram, Muhammad Zubair; Ali, Madad
    Malnutrition and climatic changes are the most significant issues nowadays. The present form of food is not acceptable and balanced nutrition. Besides, much food can be destroyed by climatic changes. There must be some crops that we can consider for future food security. There is a need to explore crops rich in nutrition that can survive in such climatic conditions. Some crops have such qualities that are considered super and functional foods. These foods have higher nutrition and are also rich in some phenolic compounds that are medicinally proven against a specific disease; that is the reason we call them super and functional food. Amaranthus is one of them. It has higher protein quality and quantity than our staple food, wheat, barley and maize. Some of the lines of amaranth report a protein content of more than 21%. It contains higher minerals and vitamins in it. The plant makes a beautiful landscape; because of this, it is mostly used for landscaping, but now many scientists are working on it considering this crop good not for beautification but for high nutrition and high tolerance against global climate changes. Amaranthus has the potential to survive in changing climatic conditions. It is resistant to drought, salinity and heavy metals as some studies confirm. This review comprises morphology, nutrition and climatic resilient properties of amaranth. © 2022, University of Zagreb, Faculty of Mining, Geology and Petroleum Engineering. All rights reserved.

    Evaluation of Various Agro-Morphological and Genetic Parameters of Single Cross Doubled Haploid Maize Hybrids
    (ResearchersLinks Ltd, 2022) Ali, Madad; Ahsan, Muhammad; Akram, Muhammad Zubair; Nazeer, Samreen
    Maize (Zea mays L.) is among the most important crops in the world for its nutritional value and productivity. Skyrocketing populations demand more food to consume without expansion in agricultural land which can be achieved by utilizing hybrid vigor. A field trial during 2018 was conducted at the University of Agriculture Faisalabad to screen out the best single cross doubled haploid hybrids of maize using eleven doubled haploid single cross hybrids. A randomized complete block design was used to conduct the experiment with three replications under normal environmental conditions. Data for different growth, yield, and agro-morphological parameters were analyzed at a 5% probability of the HSD test. Significant differences were present among the doubled haploid maize hybrids for all the studied agro-morphological parameters. Grain’s yield showed the highest positive and significant genotypic correlation with plant height (r = 0.784) followed by number of leaves per plant (r = 0.715). Grains yield also showed the highest positive and significant phenotypic correlation with plant height (r = 0.469) followed by total biomass (r = 0.431). Number of grain rows per cob (r = 2.662) exhibited the highest positive direct effect on grain yield per plant followed by total biomass (r = 1.993) and 100 grains weight (r = 1.194). Among the hybrids understudy, DH-8XDH-6 showed the best performance in Plant height (196.67 cm), Leaves per plant (14), total biomass per plant (440.91 g), cob length (18.169 cm), 1000 grain weight (40.47 g) and grain yield per plant (274.92 g), thus is recommended for further production and research. © 2022 by the authors.

    Gene regulation in halophytes in conferring salt tolerance
    (Elsevier, 2020) Hafeez, Muhammad Bilal; Raza, Ali; Zahra, Noreen; Shaukat, Kanval; Akram, Muhammad Zubair; Iqbal, Shahid; Basra, Shahzad Maqsood Ahmed
    Salinity is one of the significant stresses that affect all the metabolic and physiological aspects of all the plants, and on this consistency, some genes are upregulated, and some are downregulated to confer salt stress. In this aspect, halophytes are enriched with all the essential machinery to overcome salt stress by switching genetic pathways that inhibits the entry of toxic ions (Na+ ions and Cl- ions), or by compartmentalization of these ions in subcellular organelles, which not only protect the plants at germination stage but also provide protecting shield at growth and developmental level. Na+ flux entered from roots to leaves, and it enters at cellular level accomplished via KUP/HAK/KT, KT, HKT1, AKTI, and NSCCs (nonspecific cation channels) transporters. Available literature indicates that at germination stage, Cdc2-related protein, Vp1 and MIP proteins (proteins of aquaporins) related to transcripts, and DOG1, AB15, and RGL2 genes are upregulated in halophytes. Besides, at developmental stages glycine-rich RNA-binding proteins (SvGRP1 and SvGRP2), APX (ascorbate peroxidase) gene, TsApx6 is switched on to overcome salinity stress. In this content, cytoplasmic damage is controlled by the upregulation of genes involved in ionic compartmentalization such as NHX, CLC, and AQP. Furthermore, SOS, HA1, NHX, VAMP, CLC, PIP, SOS1, PIP (aquaporin involved in salt secretion), and TIP genes are upregulated for salt secretion; a specific attribute is only related to halophytes. Moreover, for intragenic recycling roots hydrophobic barriers genes cytochrome P450 (involved in the hydrophobic root barrier) SOS1 and AoCYP86B1 are switched on. The damaging effect of salt can be at least, and partially reversed by the expression of these genes in glycophytes and other halophytes. These findings have enormous implications for growing halophytes and glycophytes in the areas where salinity is a major limiting factor for plant growth and development. © 2021 Elsevier Inc.

    Physiological and molecular responses to high, chilling, and freezing temperature in plant growth and production: consequences and mitigation possibilities
    (Springer International Publishing, 2021) Zahra, Noreen; Shaukat, Kanval; Hafeez, Muhammad Bilal; Raza, Ali; Hussain, Sadam; Chaudhary, Muhammad Tanees; Akram, Muhammad Zubair
    Temperature is the main factor that determines the geographical distribution of plants both in the context of altitudinal and latitudinal gradients. Temperature is a primary physical factor affecting the rate of plant growth and development in all the species across different regimes. Prolonged extreme temperatures, either temperatures below and above certain thresholds during critical periods of developmental stages, have severe consequences on plant productivity and grain quality. In addition to flowering time, low temperature (LT) causes short hypocotyls and compact rosettes, and higher temperature causes lower viability of pollens and anthers, thereby causing severe economic losses. It alters the plant metabolism, and this short-/long-term modulation after exposure to high temperature (HT), low temperature (LT), and freezing temperature (FT) affects the important macromolecules (DNAs, protein) and super molecules (membranes, chromosomes). To combat the adversities of extreme temperature antioxidants activities, photosynthetic assimilate transport and heat shock proteins (HSPs) activation causes direct and indirect acclimation, thus protecting plants and enhancing plant growth and productivity. The responses of plants under temperature fluctuations have been widely investigated; however, in-depth studies related to adaptive responses of the plant at the molecular and physiological level are still lacking. Plants acquire resistance to every single degree increase/decrease in temperature by modulating genetic makeup and underlying key physiological processes. This chapter aims to document parallel-in-time changes during extreme temperature, and exploring new advancement in biotechnological tools to enhance plant tolerance at the genomic level, which could lead to the generation of new resistant/tolerant varieties with sustainable yield and production. Therefore, in this chapter, we underline and summarize the recent progress in the physiological, biochemical, and molecular responses as tolerance mechanisms under HT, LT, and FT. Moreover, some mitigation approaches, such as QTLs, GWAS, MAS, PGRs, and plant leaf extracts, are also discussed in detail. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.

    Rhizosphere Engineering and Soil Sustainability: An Introduction
    (IGI Global, 2022) Nazeer, Samreen; Akram, Muhammad Zubair; Ali, Madad
    Soils are a vital part of agricultural production. Soil health plays a significant role in the best crop production. Nowadays, our lands are under immense pressure. This pressure may be in the form of climatic changes that affect crop productivity or may be due to population increment that forces our current food system to produce more food to meet consumer needs. Climatic changes affect soil sustainability in the wrong way. Salinity, drought, and heavy metals disturb land structure badly. As the population increases, it dramatically impacts the current production system to fulfill the present needs. In all these situations, agricultural soil sustainability is a challenging factor for soil scientists to make our agriculture sustainable because agricultural sustainability couldn’t be possible without maintaining soil health. Many approaches are available to improve soil structure and health. Among these, plant growth-promoting rhizobacterium is a good option. It not only improves soil structure but also helps the plants under abiotic stress conditions. © 2022 by IGI Global. All rights reserved.
