Plant tissue culture is a technique that enhances the quality and quantity of potatoes. Potatoes are a significant crop and are primarily used in the world. It is a staple food in many countries, where millions of tonnes are produced annually. It is an essential source of many nutrients, such as proteins, carbohydrates, vitamins, and beta-carotene. In addition, potatoes are being used as therapeutic agents against cancer and other human diseases as well. Potatoes are on the third list after wheat and rice. To overcome food shortages and malnutrition, there are two methods used for producing potatoes: the first is sexual, which is seed propagation, and the second is asexual, which is plant tissue culture propagation. Conventional potato breeding is a uniform method, but it is unsafe because there is a risk of pathogen attack. In a laboratory setting, the tissue culture of potatoes produced millions of plants with nutrient-rich medium under controlled environmental conditions that prevent pest attacks. Some environmental stresses, such as salinity and water scarcity, affect potato yield and production;however, applying nanoparticles like organic, inorganic, and silicon dioxide enhances potato quality and combats stress. Biotechnology has proven to be helpful in addressing all these issues. This review discusses the significance of potatoes, their production through the tissue culture technique, and the application of nanoparticles to improve the growth, and impact of potatoes on human health.

为了探究脂质代谢在抵抗铵胁迫中的具体作用,本研究以一株高耐铵菌株Bacillus aryabhattai NM1-A2为研究对象,通过全基因组和转录组分析挖掘脂质代谢通路和关键基因,利用实时荧光定量PCR对筛选的差异表达基因进行定量分析,并测定丙二醛含量和抗氧化酶活性.结果表明,铵胁迫下脂肪酸合成相关基因(accC、fabG和fabF等)均上调表达,脂肪酸降解相关基因(ACSL、fadB和fadN等)大多下调表达,可能导致脂肪酸积累.醛脱氢酶编码基因ALDH上调表达以减少脂质氧化产物的积累.此外,铵胁迫诱导超氧化物歧化酶、过氧化物酶和过氧化氢酶表达水平和活性的提高,以减少活性氧产生和细胞损伤.因此,活跃的脂质代谢和抗氧化酶系统是*** NM1-A2抵抗铵胁迫的重要途径.

Dramatic changes in climatic conditions that supplement the biotic and abiotic stresses pose severe threat to the sustainable rice production and have made it a difficult task for rice molecular breeders to enhance production and productivity under these stress factors. The main focus of rice molecular breeders is to understand the fundamentals of molecular pathways involved in complex agronomic traits to increase the yield. The availability of complete rice genome sequence and recent improvements in rice genomics research has made it possible to detect and map accurately a large number of genes by using linkage to DNA markers. Linkage mapping is an effective approach to identify the genetic markers which are co-segregating with target traits within the family. The ideas of genetic diversity, quantitative trait locus（QTL） mapping, and marker-assisted selection（MAS） are evolving into more efficient concepts of linkage disequilibrium（LD） also called association mapping and genomic selection（GS）, respectively. The use of cost-effective DNA markers derived from the fine mapped position of the genes for important agronomic traits will provide opportunities for breeders to develop high-yielding, stress-resistant, and better quality rice cultivars. Here we focus on the progress of molecular marker technologies, their application in genetic mapping and evolution of association mapping techniques in rice.
