Bean bruchids are among the most devastating insect pests of common bean that can inflict huge losses in storage. To identify potential resistance to these pests, screening was performed at Sokoine University of Agriculture. Two resistant landraces were identified, viz Kalubungula and KK25. Recombinant inbred (RI) KSy, KSw and ML populations were created from crosses between Soya × Kalubungula, Soworo × Kalubungula and Nagaga × KK25, respectively. Seed storage proteins were characterized and sequenced in RI population progenies to determine if phenotypic resistance was associated with α-amylase inhibitor – phytohemagglutinin – arcelin (APA) storage proteins. We found no association between the seed storage proteins observed in Kalubungula and its recombinant inbred lines with an APA protein. KK25 and its progenies had Arcelin-5, Leucoagglutinin, Erythroagglutinin and a hypothetical seed storage protein that conditions antibiosis effects as a resistance mechanism. The hypothetical seed storage protein observed in these lines may contribute to enhanced resistance. arcelin, Acanthoscelides obtectus , Zabrotes subfasciatus , common beans.

The effect of foliar application of nitrogen-phosphorus-potassium (NPK) fertilizers on nutritional status and yield of maize ( Zea mays L.) were investigated through a study conducted in a zonal agricultural research station of University of Agricultural Sciences, GKVK Bengaluru (India). The experiment was laid out in randomized complete block design. The treatments consisted of two levels of soil application (75 and 100%) of recommended dose of fertilizer (RDF) and foliar applications of NPK (19:19:19). The fertilizers were applied at 6-leaf, tasselling, knee height and tasseling growth stages. Nutrient uptake, protein content and available soil nutrients at harvest were analyzed. Results indicated that soil application of 100% RDF along with foliar sprays of NPK at knee height and tasselling stages significantly produced the highest levels of N, P and K uptake (306.60, 100.57 and 216.24 kg ha -1 , respectively) and maximum protein content (11.5%). Use of this fertilizer treatment also resulted into highest available soil N (273.74 kg ha -1 ), P (59.45 kg ha -1 ) and K (204.88 kg ha -1 ). The combined soil application of 100% RDF and foliar application of NPK at knee height and tasseling stages has potential to increase nutrient supply and protein content of the maize crop.
通过在印度班加罗尔GKVK农业科学大学区域农业研究站进行的一项研究，研究了叶面施用氮磷钾（NPK）肥料对玉米营养状况和产量的影响。实验采用随机完全区组设计。处理包括两个水平的土壤施用（75%和100%）推荐剂量的肥料（RDF）和叶面施用NPK（19:19:19）。在6叶期、抽雄期、齐膝期和抽雄期施肥。分析了收获期的养分吸收、蛋白质含量和土壤有效养分。结果表明，在齐膝期和雄穗期施用100%RDF和叶面喷施NPK可显著提高土壤对N、P和K的吸收水平（分别为306.60、100.57和216.24kg ha-1）和蛋白质含量（11.5%），P（59.45 kg ha-1）和K（204.88 kg ha-2）。在齐膝期和雄穗期土壤施用100%RDF和叶面施用NPK有可能增加玉米作物的营养供应和蛋白质含量。

Sorghum [Sorghum bicolor (L.) Moench], is believed to be originated in Ethiopia and Sudan. Although, many morphological and molecular diversity studies reveal the existence of genetic variations with sorghum populations, their distribution within basic races were not considered. Hence, the present study aimed to analyze the extent and distribution of genetic variation within basic Ethiopian sorghum landraces using SSR markers. A total of 107 landraces obtained from Ethiopian Biodiversity Institute (EBI) representing 12 ecological zones grouped according to their race types based on inflorescence and spiklet on field at their maturity time. Twelve SSR markers revealed a total of 110 alleles with average polymorphic content of 0.76 and the allele frequencies show 42 of them were rare (less than 0.05), 22 ranged from 0.05 to 0.1, while 46 of them were higher than 0.1. Expected and observed heterozygosity were 0.78 and 0.2, respectively. The genetic differentiation between populations were also moderate (FST=0.07 for races and 0.13 for E/zones) indicating continuous exchange of genes among them. Partitioning the total genetic variation also indicated 61.38 and 55.17% of the variations were among individuals within racial and zonal populations, respectively. Neighbor-Joining cluster analysis also indicated four major grouping of the landraces according to their racial groups where majority of race caudatum and durra form separate groups while intermediate durra-bicolor form two separate subclusters. Overall locus, the intra-racial population diversity showed the greatest genetic diversity (He=0.77 and 0.75) among race dura-bicolor and caudatum, respectively. Information with sorghum races along their important agronomic traits could be used for conservation and future breeding programs of sorghum.

Hormesis is a biphasic dose (concentration)-response phenomenon characterized by low dose stimulatory and high dose inhibitory effects exerted by stressors on living organisms. Recently, there has been increased interest in the phenomenon and statistical models for its exploration in toxicological studies. The bilogistic model of Beckon et al. is one of such models for modeling biphasic dose-response relationships in toxicological studies. However, there is no explicit formula for the estimation of effective doses (EDK) with the model. In this study, a simple general approach was suggested to reparameterize the model, leading to a range of mathematical models for determination of effective doses at both stimulatory and inhibitory ranges in inverted U-shaped hormetic dose-response relationships. The reparameterized models were tested on experimental data from three different in vitro experimental systems obtained from literature and our experiment. They were successfully applied to test for significance of hormesis and estimate effective doses and their statistical properties. In addition, reparameterization of the model for a particular effective dose (EDK) did not affect estimation of other parameters (such as x1, x2, β1, β2 and M). The reparameterized models provided useful tools for adequate exploration of the tested hormetic dose-response relationships. The extended models could hopefully be versatile in characterization of variable hormetic dose response relationships in many toxicological disciplines.

Thanks to committed plant breeding researchers over the few decades, many problems associated with food supply and qualities have been improved. Food security is an exceptionally serious worldwide issue via world climate change, the increase in human population, and the use of plants for bioethanol production in current years. Improved tolerance to abiotic and biotic stress, resistance to herbicides, improved yield, and plants with wonderful nutritional value are essential goals of crop improvement. RNAi applications are the modern innovation that can assist in the solution for these issues. A natural protection mechanism against invading viruses, nucleic acids, and transposons non-coding RNAs (ncRNAs), are identified as effector molecules in RNA-mediated gene silencing and used in the genetic modification of crops. These ncRNAs are concerned with the regulation of growth, development, and response to stress at the transcriptional and translational levels. Improving crop yields is the final purpose of molecular plant breeding. ncRNAs, along with transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), as well as small non-coding RNAs (sncRNAs) and the long non-coding RNAs (lncRNAs), have been recognized as essential regulators of gene expression in plants in plant immunity and adaptation to abiotic and abiotic stages biotic stress.

Abeliophyllum distichum Nakai is a deciduous shrub that belongs to Oleaceae Abeliophyllum and grows only in Korea. In this study, the antioxidative activity, cytotoxicity, anti-aging activity, and levels of acteoside and isoacteoside were compared between non-fermented and fermented (using Lactobacillus plantarum and Lactobacillus brevis) extracts of A. distichum Nakai. The cytotoxicity of these extracts, along with their ability to inhibit elastase activity and Matrix metalloproteinase-1 (MMP-1) expression, and their ability to promote type I procollagen synthesis were investigated in human dermal fibroblasts cells. These tests revealed that the fermented extract possessed higher antioxidant and anti-aging activities compared with the non-fermented extract. The levels of acteoside and isoacteoside were about 1.25 and 1.05 times higher in the fermented extract than in the non-fermented extract. It was speculated that they were converted from acteoside glucosides and isoacteoside glucosides via bioconversion by the fermentation strains. Together, these findings indicate that extracts of A. distichum Nakai show good potential as antioxidative and anti-aging cosmetic materials. Key words: Abeliophyllum distichum Nakai, Lactobacillus plantarum, Lactobacillus brevis, fermentation, antioxidative activity, anti-aging activity.
