Improving the soil structure and fertility of saline–alkali land is a major issue in establishing sustainable agro-ecosystem. To explore potential different straw returning improving saline–alkaline land, we utilized native (SCK), wheat straw-returned (SXM) rapeseed (SYC) as our research objects. Soil physicochemical properties, fungal community diversity soils were investigated treatments at 0–10 cm, 10–20 cm 20–30 depths. The results showed that SXM SYC reduced pH total salinity but...
Sugars will eventually be exported transporter (SWEET), a class of glucose transport proteins, is crucial in plants for by redistribution sugars and regulates growth, development, stress tolerance. Although the SWEET family has been studied many plants, little known about its function winter B. rapa (Brassica L.).

Glyoxalase I (GLYI) is a key enzyme that detoxifies methylglyoxal, toxic byproduct of glycolysis, and essential for plant pollination. However, the genome-wide identification functional analysis GLYI in Brassica rapa L. (B. rapa) remain limited. This study identified 17 BrGLYI genes (BrGLYI1–BrGLYI17) from B. genome. The self-compatible line 039-1 self-incompatible GAU-28-5 were used as experimental materials, Real-Time Quantitative Reverse Transcription PCR (RT-qPCR) was performed to...
Winter rapeseed (Brassica rapa L.) is the main oilseed crop in northern China and can safely overwinter at 35 (i.e., Tianshui, China) to 48 degrees north latitude Altai, Heilongjiang, Raohe, Xinjiang, China). In order identify stable reference genes understand molecular mechanisms of stress tolerance winter rapeseed, internal under four abiotic stresses were analyzed using GeNorm, NormFinder, BestKeeper, RefFinder software. The most combinations β-actin SAND cold-stressed leaves, EF1a roots,...
Winter Brassica rapa (B. rapa) is an important oilseed crop in northern China, but the mechanism of its cold resistance remains unclear. Ascorbate peroxidase (APX) plays roles response this plant to abiotic stress and scavenging free radicals. In study, APX proteins superoxide metabolism pathways rapeseed species were investigated, a comprehensive analysis phylogeny, chromosome distribution, motif identification, sequence structure, gene duplication, RNA-seq expression profiles family was...
Zinc-finger protein (ZFP) transcription factors are among the largest families of in plants. They participate various biological processes such as apoptosis, autophagy, and stemness maintenance play important roles regulating plant growth development response to stress. To elucidate functions ZFP genes low-temperature winter (Brassica rapa L.) B. rapa, this study identified 141 members C2H2 gene family from which heterogeneously distributed on 10 chromosomes have multiple cis-acting elements...
摘要: 采用多点试验,对冬油菜在原种植区(天水)与北移种植区(张掖等)的主要气候因子、越冬率、生育时期及经济性状进行分析比较。研究结果表明,冬油菜北移后越冬率由原种植区的93.0%~100.0%降为40.0%~95.0%;生育期由280~284 d延至287~289 d,其冬前与冬后生长期缩短,而越冬期延长1倍左右,即140 d左右,整个生长期呈'短-长-短'的特点,即营养生长有效期缩短及营养生长至生殖生长的过渡期均缩短;株高与分支部位降低, 分支数减少,单株角果数减少, 但千粒重、角粒数等相对增加。冬油菜北移后产量发生了较大变化,抗寒性弱的早熟品种天油8号由原种植区的2 518.8 kg hm–2降为1 666.5 hm–2,减产34.0%,而抗寒性强的晚熟品种陇油6号等由原种植区的741 hm–2增加到3 333 hm–2,增幅349.5%。由于生长在相对恶劣的气候生态条件下,越冬期漫长而极端低温低,北移冬油菜栽培品种必须具备优异的抗寒性,同时采用合理播期和密度,保证冬前营养生长期和营养生长量,以确保安全越冬。
Abstract Winter and early spring wind soil erosion have considerable impacts on ecosystems, human well-being agricultural production in the low precipitation zones of northern China. Little is known about impact growing winter rapeseed ecological cropping systems associated economic benefits area. To explore cover effect, we conducted a field experiment which covered with rapeseed, wheat stubble at different plant density levels used bare ground as control (CK). The effects erosion, “winter...
Abstract Winter rapeseed ( Brassica rapa L.) is a major oilseed crop in Northern China, where its production was severely affected by chilling and freezing stress. However, not much known about the role of differentially accumulated proteins (DAPs) during In this study, isobaric tag for relative absolute quantification (iTRAQ) technology performed to identify DAPs under To explore molecular mechanisms cold stress tolerance at cellular protein levels, morphological physiological differences...
