This study aimed to create new rice lines with a strong resistance to blast disease and a high tolerance to submergence. This was achieved by introducing Pi and Sub1 QTLs into the popular local rice variety, Pulau Batu using a 4-way marker-assisted breeding technique. The progenies were evaluated both phenotypically and genotypically to identify th...

Rice is frequently subjected to various environmental stresses, resulting in significant production losses, with drought and salinity are the leading causes of plant damage globally. This study aims to characterize and understand the function of rice high-affinity potassium transporters ( HKTs ) genes in response to salinity stress. Initially, the...

This study investigates the submergence tolerance level of 14 rice genotypes by morpho-physiological and molecular analyses of Sub1 alleles. IR64-Sub1 was used as a submergence tolerant check. The submergence screenings were conducted by submerging 14-days-old seedlings in water tanks for 14 days while molecular analysis was conducted using 14 Sub1...

Various varieties have been developed in Malaysia, mainly to improve rice response to environmental changes, pests, and diseases, as well as to increase rice productivity under stressful conditions. Despite being semi-aquatic plants, rice is intolerant to complete submergence for a long period. This study was conducted to evaluate the response of s...

Soil salinity is one of the most serious environmental challenges, posing a growing threat to agriculture across the world. Soil salinity has a significant impact on rice growth, development, and production. Hence, improving rice varieties’ resistance to salt stress is a viable solution for meeting global food demand. Adaptation to salt stress is a...

Abstract This study focuses on the growth and morpho-physiological responses of the Malaysian commercial variety MR219 rice to salinity stress during the early vegetative stages, specifically during germination and the five-leaf stage. For germination responses, MR219 seeds were grown for 10 days in different salt concentrations. Low salinity sign...

Auxin Binding Protein 57 (ABP57) is one of the molecular components involved in rice response to abiotic stress. The ABP57 gene encodes an auxin receptor which functions in activating the plasma membrane H+-ATPase. Biochemical properties of ABP57 have been characterized; however, the function of ABP57, particularly on stress and hormone responses i...

MR219 transgenic rice line which overexpressed an auxin-binding protein (ABP57) and its wild-type cultivar, MR219, were screened under well-watered (WW) and drought stress (DS) conditions at the early reproductive stage. This study was conducted with the standard planting distance and under a normal environment to assess the yield advantages based...

Abiotic stress is one of major constraints in crop production worldwide. Drought is the most important abiotic stress that has a huge impact on plant growth and productivity. Rice is one of the crops that is sensitive to water limited conditions and prolong drought stress causes yield loss. Many genes are also affected by drought stress and informa...

Key message Morphological and transcriptomic evidences provide us strong support for the function of ANAC019 in reproductive development under drought stress. Abstract Plants are sensitive to drought conditions, particularly at the reproductive stage. Several studies have reported drought effects on crop reproductive development, but the molecular...

Increased tolerance to multiple abiotic stresses in plants is a key target for food security. OsSAP8 is a member of the stress-associated protein (SAP) gene family in rice and is characterized by the presence of two zinc finger domains, A20 and AN1. In this research, we aim to understand the regulatory mechanism of OsSAP8 in response to multiple st...

Plants possess different mechanisms in stress response, where induction of stress-responsive genes provides tolerance to unfavorable conditions. Stress-responsive genes are characterized for functional and regulatory genes that help in overcoming stress by molecular, biochemical and morphological adaptations. NAC transcription factors are one of th...

Background Drought is a major constraint that leads to extensive losses to agricultural yield worldwide. The potential yield is largely determined during inflorescence development. However, to date, most investigations on plant response to drought have focused on vegetative development. This study describes the morphological changes of reproductive...

Drought dramatically affects plant growth and crop yield, but previous studies primarily examined responses to drought during vegetative development. Here, to study responses to drought during reproductive development, we grew Arabidopsis thaliana plants with limited water, under conditions that allowed the plants to initiate and complete reproduct...

Plants are sessile and must withstand different environmental stresses, such as drought, salt and various temperatures. Such stresses often greatly reduce plant reproductive yield, but studies of the effects of environmental stress have largely focused on vegetative development. In addition, detailed analyses of reproductive development have been p...
