Autophagy is a basically survival mechanism of body in which cell digests its own content to maintain cellular homeostasis in multiple stress conditions and starvation. The term ‘autophagy’ was first described in 1963 by Christian de Duve, a Japanese cell biologist to describe presence of double-membrane vesicles containing cytoplasmic constituents within the cell. These vesicles that encapsulate cytoplasm, organelles and proteins, are known as autophagosomes. After formation of autophagosome it fuses with endosomes and travels via cytoplasm to fuse with lysosomes for degradation. In lysosomes internal content material of autophagosome is degraded with the action of acid hydrolases. Autophagy is very important for regulation of diverse cellular functions i.e., growth, differentiation, response to nutrient deficit and oxidative stress, cell death and macromolecule and organelle turnover. Nutrient starvation is most typical trigger of autophagy. Depending on the mechanism by which intracellular materials are delivered into lysosome for degradation, there are four types- Macroautophagy, Microautophagy, Chaperon mediated autophagy and Crinophagy. Autophagy is important in normal development and it responds to changing environmental stimuli. It plays role in cancer and numerous important diseases such as bacterial and viral infections, liver and kidney diseases, Diabetes mellitus, inflammatory bowel diseases, neurodegenerative disorders, several myopathies and cardiovascular diseases.
自噬是人体的一种基本生存机制，细胞通过消化自身内容物来维持细胞在多种压力和饥饿条件下的平衡。自噬 "一词最早由日本细胞生物学家克里斯蒂安-德-杜夫（Christian de Duve）于1963年描述，用来描述细胞内存在的含有细胞质成分的双膜囊泡。这些包裹着细胞质、细胞器和蛋白质的囊泡被称为自噬体。自噬体形成后与内质体融合，并通过细胞质与溶酶体融合进行降解。在溶酶体中，自噬体的内部物质在酸水解酶的作用下被降解。自噬对调节多种细胞功能（如生长、分化、对营养缺乏和氧化应激的反应、细胞死亡以及大分子和细胞器的周转）非常重要。营养饥饿是自噬最典型的触发因素。根据细胞内物质被送入溶酶体降解的机制，自噬可分为四种类型--巨自噬、微自噬、伴侣介导的自噬和嗜铬自噬。自噬对正常发育非常重要，它能对不断变化的环境刺激做出反应。它在癌症和许多重要疾病中都发挥着作用，如细菌和病毒感染、肝脏和肾脏疾病、糖尿病、炎症性肠病、神经退行性疾病、多种肌病和心血管疾病。

Strawberry is most economically important fresh and processed fruits, consumed both for its pleasant flavor and its nutrient content. Due to the fruit’s high concentration of antioxidants and phytochemicals, eating strawberries has been linked to maintain good health and preventing the development of chronic diseases. The following information has been compiled from previous year research papers, which contain valuable insights into the health benefits, nutritional status and effects of strawberries. Balanced nutrition is needed by delicate strawberry plants so it’s important to maintain the nutritional status for better growth, yield and quality of strawberry fruits. Although strawberries are a highly perishable fruit and cannot be kept for an extended amount of time, several wrapping techniques have preserved the fruit’s quality when kept at ambient temperature. Disorder like albinism can be corrected with proper spacing and spray of borax and GA3. One step toward helping farmers maximize their profits is the notion of waste utilization in horticultural crops. Therefore, the goal of doubling farmer’s income by minimizing their after-harvest losses and enhancing the demand of perishable cultivable fruit crops is achieved. This review paper showing different practices related to strawberry like its propagation, metabolites and health benefits, biochemistry of fruit ripening, effect of micro and macronutrients on strawberry’s growth, yield and quality.

The central part of the country in the world classified Maize as their staple and essential crop, but this crop cannot cultivate appropriately in acidic soil. Thus, biochar, silicon and phosphorus observation can act as an agent to improve the growth of Maize in acidic soil. Additionally, biochar, well known for its alkaline properties, can reduce soil acidification and, at the same time, improve crop production. This low pH condition was caused by aluminium, manganese and low of phosphorus. Thus, silicon and Phosphorus can improve crop productivity. Using biochar as a soil amendment raises the pH value, alone or in combination. Maize (Zea mays L.) and the acidity of the soil are much related to the application of biochar combined with silicon and Phosphorus. Biochar simply can reduce exchangeable soil acidity, but when combined with silicon and Phosphorus, it can have a greater influence on reducing soil Al toxicity. The importance of biochar with different rates combined with silicon and Phosphorus to increase the pH of soil is still an inconsistent result by various studies. This review summarizes the properties of biochar, silicon and phosphorus and provides the scientific reference for its application to archive high yield of Maize and reduce the acidification effect on soil.

Micronutrient deficiency is a big concern around the world since it causes serious social and health problems. Micronutrient availability is low on millions of hectares of land around the world, including India. Zn deficiency in Indian soils has reached 47% and Fe deficiency has reached 13%. The main causes of micronutrient deficit in soil are excessive fertilizer use (over the RDF), soil erosion and other agronomic practices that obstruct the movement of micronutrients. A promising and sustainable agriculture-based method called biofortification aims to reduce Zn and Fe deficiencies in dietary food ingredients. The plant breeding method to create biofortified crops and agronomic supplementation of micronutrients, such as foliar/soil application together with chemical fertilisers, have drawn the most attention among the various strategies used. Interactions between plants and microbes are recognised to be essential for enhancing the nutrient status of the soil and enriching micronutrients through the solubilization, mobilisation and translocation of metals to various parts of the plant. This symbiotic relationship enhances the quality and yield of crops, while innovative food processing techniques can offer cost-effective biofortified food solutions to address the nutritional needs of undernourished populations.Micronutrient deficiency is a big concern around the world since it causes serious social and health problems.

Background: Assam is considered as a flood prone state, as this natural disaster creates devastating situation almost every year. The study was conducted in Dhemaji district of Assam which is in the list of highly flood hazard index. The district was selected to know the impact of flood on financial loss for agricultural production and to study the mitigation strategy adopted by the flood affected farmers in the district. Methods: For that a multistage random sampling technique was adopted to select flood affected farmers from the district. Financial loss for agricultural production due to flood was estimated by calculating financial loss for crop loss, agricultural asset loss and livestock loss for the study area. Flood situation and Non flood situation was compared while going for calculation of financial loss for crop due to flood. Henry Garret ranking technique was adopted to rank the problems face by the farmers. Result: The result reflected that net return from crop production was recorded to be less (Group I 1032.44Rs/ha and Group II 3830.99 Rs/ha) in flood situation than the non-flood situation (Group I 7051.30 Rs/ha and Group II 8330.08 Rs/ha).Total financial loss due to crop loss, asset loss and livestock loss was found to be high for size group II farmers (Rs 39094.33) then the size group I (Rs 36643.40). Majority of the respondents (79.17 per cent) preferred migration as the best coping mechanism to protect them from flood loss.

Study of isotherms and thermodynamic properties become essential to understand the drying and imbibition mechanisms of seeds. Among post-harvest procedures of seeds, drying is widely known and used in order to assure quality and stability during storage and shelf life. Variation of moisture content through drying is important in order to understand the interaction between water molecules and the seed components, which is the key factor for correct drying and storage. Seed viability could be maintained during long periods owing to their glass structure, as a thermodynamic unstable state, with high viscosity. Thermodynamic properties were enthalpy (Amount of energy available to do work), entropy (Amount of energy present but it not available to do work) and gibbs free energy (Differential energy between the enthalpy and entropy). Thermodynamic properties of seed water determines the reaction kinetics during seed deterioration. Thermodynamic properties showed a critical upper limit, with tolerant species having higher values then susceptible species. In general the values of critical limits of the thermodynamic parameters decreased with increasing temperature. The differential enthalpy and entropy increased in seeds with period of storage and became asymptotic as the seed lost their viability. Thermodynamics properties increased with increase in temperature, indicating that drying and water absorption do not occur spontaneously it requires external energy. A radical drop in germination follows the trend of gibbs free energy increase and enthalpy decrease, indicating intensification of endergonic reaction. Hence, it is concluded that by using thermodynamic properties of seeds the seed quality can be determined without conducting the germination test in shortest period.

Plant diseases pose a significant threat to global food security, leading to substantial yield losses and economic damage. In recent years, irradiation technology has emerged as a promising approach to enhance plant disease resistance. Gamma irradiation, a well-established technique, has been utilized for approximately 60 years to develop new plant varieties with improved resistance to pests and diseases. X-ray is another form of ionizing radiation, has also shown the potential in enhancing plant disease resistance. UV light, including UVB and UVC radiation, has been effective in eliminating microorganisms by damaging their DNA. Electron beam irradiation, a non-ionizing form of radiation, has been investigated for its impact on plant disease resistance. However, the implementation of irradiation technology in agriculture faces challenges such as public perception, regulatory barriers and cost-effectiveness. This review article highlights the advances in irradiation technology for plant disease resistance. It emphasizes the potential of gamma irradiation, X-ray gamma irradiation, UV light, UVB, UVC and electron beam in enhancing plant disease resistance.

Cisgenics is the change of a recipient plant’s genetic make-up using a naturally derived gene from a species that is cross-compatible, along with its introns, native promoter and terminator, which are flanked at the typical sense orientation. It simply refers to genetic alteration carried out using one among the recombinant DNA technology approaches without the use of any foreign DNA; in other words, the host plant’s DNA or DNA from the closely related species that is sexually compatible is used only in the manipulation. There is a public concern about eating transgenic plants, although genetically altered features offer priceless alternatives to conventional breeding. Because apples are vegetatively propagated, their heterozygous nature further hampered the successful transfer of desirable features. As a result, it is possible to directly transfer desired genes through cisgenesis into an existing variety without changing any of the desirable traits for customers. The benefits of cisgenesis over conventional breeding include its ability to overcome linkage drag, maintain the genetic diversity of the plant variety, use less pesticides and save time. The use of cisgenic approaches in various fruit crops increases the possibility of introducing the desired genes into innovative cultivars without affecting their beneficial traits.c
同源基因改变是指使用来自异源物种的天然基因，连同其内含子、原生启动子和终止子，改变受体植物的基因组成。简单地说，它是指利用 DNA 重组技术中的一种方法改变基因，而不使用任何外来 DNA；换句话说，在操作过程中只使用宿主植物的 DNA 或来自性状相容的近缘物种的 DNA。虽然基因改变的特征为传统育种提供了无价的替代品，但公众对食用转基因植物仍有顾虑。由于苹果是无性繁殖，其杂合性进一步阻碍了理想特性的成功转移。因此，可以通过顺式育种将所需基因直接转移到现有品种中，而不改变客户的任何理想性状。与传统育种相比，顺式育种的优势在于能够克服连接阻力、保持植物品种的遗传多样性、减少农药使用量并节省时间。在各种水果作物中使用顺式育种方法增加了将所需基因引入创新栽培品种而不影响其有益性状的可能性。

The use of cisgenic approaches in various fruit crops increases the possibility of introducing the desired genes into innovative cultivars without affecting their beneficial traits.c","PeriodicalId":7417,"journal":{"name":"Agricultural Reviews","volume":"23 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139237400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity of crop yields, the environment and its effect on food security and the quality of life. However, the on-site impacts of land degradation on productivity are easily screened due to use of additional inputs and adoption of improved technology and have led some to question the negative effects of extreme land degradation. The relative magnitude of economic losses due to productivity decline versus environmental deterioration also has created a debate. Therefore, land is a non-renewable resource, and the productive capacity of the land would be reduced unless proper management options would be taken at a right time. The proper management options of land degradation for sustaining the crop yields are controlling overgrazing, reduced population pressures on natural resources, using energy efficient sources, contour farming, avoiding cultivation of steep slopes for crop production purposes, afforestation and hillside tree plantations and along gullies, increasing soil fertility by adding organic matter, reducing compaction of soil structures and making soil and water conservation structures to reduce soil erosion, sediment loss and run-off.
