AI Article Synopsis
- Alanine aminotransferase (AlaAT) is an important enzyme in plants that influences key processes like preharvest sprouting, stress tolerance, and nitrogen efficiency.
- The review highlights advancements in understanding AlaAT's molecular genetics, including gene cloning related to dormancy, which can impact crop yields and plant physiology.
- Future research and biotechnology strategies, such as genome editing and speed breeding, are expected to enhance the resilience of crop plants against climate change by manipulating AlaAT functions.
Article Abstract
Alanine aminotransferase (AlaAT) is a crucial enzyme present in various isoforms. It is playing vital role in both humans and plants. This concise review focuses on the role of AlaAT in plants, particularly on preharvest sprouting, hypoxia, nitrogen use efficiency, abiotic and biotic stress tolerance. The molecular genetics of AlaAT, including gene identification and the impact on plant yield and its physiology, is discussed. Notably, the major dormancy gene governing AlaAT synthesis has been characterized and cloned in various crops. This review emphasizes the current understanding of AlaAT and its influence on plants, covering mechanisms regulating preharvest sprouting, hypoxia, drought tolerance, salt tolerance, biotic resistance and nitrogen use efficiency. Identifying a protein with multidimensional roles in crop plants is very important. Modern biotechnological approaches can alter such candidate gene/protein for superior varieties development. Overall, the review gives an understanding of the uncovered area of AlaAT and the challenge of climatic change triggers in plants. In the future, the potential of genome editing in AlaAT through enhancer insertion and rapid stabilization through speed breeding will impart resilience to crop plants against climate change.

Background: Excessive fluoride exposure leads to increased oxidative stress and lipid peroxidation, causing harmful effects on the metabolic organs in the human body. Betanin, a pigment obtained from beetroot, is seen to have powerful anti-inflammatory and antioxidant. The study was conducted to determine the role of betanin in fluoride induced hepato-renal toxicity in Wistar rats.

The exclusion of cirrhosis is important in chronic hepatitis B (CHB) patients with normal alanine aminotransferase (ALT). We aimed to optimise the performance of the aspartate aminotransferase to platelet ratio index (APRI) and fibrosis score based on four factors (FIB-4) to exclude cirrhosis in these patients. Five hundred and eighty four patients with normal ALT who underwent liver biopsy were included in the study.
