Morphological, physiological and biochemical insights into heat stress response in mungbean (Vigna radiata (L.) Wilczek)
Mungbean (Vigna radiata) is a warm-season legume crop and plays a crucial role in food and nutritional security in South and Southeast Asia. Being a legume crop, it also plays a role in ecosystem sustainability. However, crop cultivation is facing an imminent threat amid the recent rise in global temperature. The optimum temperature range for mungbean cultivation is 28–35°C, although some genotypes can grow well even up to 40°C of atmospheric temperature. Therefore, in this study, 1515 mungbean accessions were initially screened for heat-responsive morphological and physiological traits to identify superior genotypes. From this preliminary screening, 75 diverse accessions were selected for a more comprehensive evaluation of heat-responsive traits. Subsequently, 32 promising genotypes were chosen for an in-depth analysis of enzymatic and nonenzymatic antioxidant activities under both heat-stressed and non-stressed conditions. Certain genotypes, namely IC76475, IC418452 and IC489062, were superior for multiple heat stress-responsive traits. The phenotypic expression of these genotypes was further validated under controlled environmental conditions. Their heat stress tolerance was confirmed through RT-PCR analysis of key candidate genes (GmAKT2, Cu/ZnSOD, APX1 and CAT1). The findings from this study will aid in developing mungbean cultivars with enhanced tolerance to heat stress.
期刊介绍：
Annals of Applied Biology is an international journal sponsored by the Association of Applied Biologists. The journal publishes original research papers on all aspects of applied research on crop production, crop protection and the cropping ecosystem. The journal is published both online and in six printed issues per year.
Annals papers must contribute substantially to the advancement of knowledge and may, among others, encompass the scientific disciplines of:
Agronomy
Agrometeorology
Agrienvironmental sciences
Applied genomics
Applied metabolomics
Applied proteomics
Biodiversity
Biological control
Climate change
Crop ecology
Entomology
Genetic manipulation
Molecular biology
Mycology
Nematology
Pests
Plant pathology
Plant breeding & genetics
Plant physiology
Post harvest biology
Soil science
Statistics
Virology
Weed biology
Annals also welcomes reviews of interest in these subject areas. Reviews should be critical surveys of the field and offer new insights. All papers are subject to peer review. Papers must usually contribute substantially to the advancement of knowledge in applied biology but short papers discussing techniques or substantiated results, and reviews of current knowledge of interest to applied biologists will be considered for publication. Papers or reviews must not be offered to any other journal for prior or simultaneous publication and normally average seven printed pages.
