BACKGROUND:The present study elucidates the protective potential of bromelain against dichlorvos intoxication in mice brains.Dichlorvos induces the oxidative stress by disproportionating the balance between free radicals generation and their scavenging in neurons which leads to neuronal degeneration.METHODS:In this study,mice were divided into four groups-group Ⅰ (control),group Ⅱ (dichlorvos treated),group Ⅲ (bromelain treated) and group Ⅳ (exposed to both bromelain and dichlorvos both).RESULTS:Dichlorvos treatment increased the levels of thiobarbituric acid reactive substances (TBARS) and protein carbonyl content (PCC) which indicate the increased oxidative stress.Meanwhile,brain endogenous antioxidants and cholinesterases level was decreased after dichlorvos exposure.Levels of TBARS and PCC decreased whereas cholinesterases level was recorded to be elevated after bromelain exposure.CONCLUSION:Bromelain offered neuroprotection by decreasing oxidative stress and augmenting cholinesterases in mice brains.This study highlights the invulnerability of bromelain against oxidative and cholinergic deficits in mice brains.

花生(Arachis hypogaea L.)是重要的油料和经济作物,在世界范围内广泛种植。花生产区主要分布在干旱、半干旱地区,干旱胁迫是影响花生产量和质量的首要限制因子。抗旱性是复杂的数量性状,受微效多基因与环境作用的影响,因此,开发花生抗旱相关分子标记对利用标记辅助育种技术提高抗旱育种效率意义重大。本研究筛选构建了花生关联分析群体,并对群体进行表型与遗传变异评估。同时系统鉴定了群体种质的抗旱性

小麦(Triticum aestivum)是世界上种植最广泛的谷物,它提供了大约20%的人类所消耗的热量。预计到2050年对小麦的需求可能会增加60%。因此,提高小麦产量尤为迫切。千粒重、单位面积穗数、穗粒数作为产量三要素是提高小麦产量的重要途径。除此之外,种质资源也在提高小麦产量上起重要作用。目前,小麦育种普遍存在种质资源匮乏等问题,迫切需要新种质的发现和创造。人工诱导产生突变体、构建突变体库,
