| 1 | Stress combination:When two negatives may become antagonistic,synergistic or additive for plants?显示文摘Plants in their natural environment are constantly subjected to various abiotic and biotic stressors and,therefore,have developed several defense mechanisms to maintain fitness.Stress responses are intricate and require various physiological,biochemical,and cellular changes in plants.The reaction mechanisms in plants subjected to drought,salinity,or heat stress alone have been explained in numerous studies.However,the field conditions are significantly different from the controlled laboratory conditions.In the field,crops or plants are simultaneously exposed to two or more abiotic and/or biotic stress conditions,such as a combination of salinity and heat,drought and cold,or any of the abiotic stresses combined with pathogen infection.Studies have shown that plants’reactions to combinations of more than two stress factors are distinct and cannot be explicitly deduced from their responses to different stresses when applied separately.Therefore,additional research is needed to understand the complete mechanism of plant responses to stress by analyzing data between single stress and multiple stress responses.This review aims to provide an overview of current research on plant responses to a combination of various stress conditions and their influence on the metabolic,transcriptional,and physiological characteristics of plants. | Hera NADEEM Amir KHAN Rishil GUPTA Mohamed HASHEM Saad ALAMRI Mansoor Ahmad SIDDIQUI Faheem AHMAD | 2023 | Pedosphere2023，33，2： | 0 |
| 2 | New insights on the utilization of ultrasonicated mustard seed cake:chemical composition and antagonistic potential for root-knot nematode,Meloidogyne javanica显示文摘This study focused,for the first time,on the effect of ultrasonic features on the extraction efficiency of secondary metabolites in mustard seed cake(MSC).The nematostatic potential of sonicated seed cake was examined against the second-stage juveniles(J2s)of root-knot nematode,Meloidogyne javanica.The results show that a 35 ppm(parts per million)concentration of a sonicated extract(SE)sample of MSC caused 65%J2s mortality at 18 h exposure period in vitro.It also significantly suppressed the root-knot index(RKI=0.94)in tomato roots.The lethal concentration values for SE were 51.76,29.79,and 13.34 ppm,respectively,at 6,12,and 18 h of the exposure period,and the lethal concentration values for the non-sonicated extract(NSE)sample were 116.95,76.38,and 55.59 ppm,respectively,at similar exposure time.Sinapine and gluconapin were identified as the major compounds in ultrasonic-assisted MSC.Because of the high extraction efficiency of metabolites in the SE,all treat‐ments of SE were shown to be antagonistic to J2s.Thus,this study of ultrasonication activity-based profiling of MSC may help generate target-based compounds at a scale relevant to the control of disease caused by nematodes in economic crops. | Hera NADEEM Pieter MALAN Amir KHAN Mohd ASIF Mansoor AHMAD SIDDIQUI Simon TUHAFENI ANGOMBE Faheem AHMAD | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021，22，7： | 0 |
