Controlled-release technology has been regarded as an alternative method for the improvement of pesticide efficiency. This study investigated two types of imidacloprid controlled-release granule (CR-GR): 2% imidacloprid CR-GR and 0.2% imidacloprid pesticide-fertilizer controlled-release granule

The expression of Lin28B was co-regulated by H3K4me2 and Wnt5a/β-catenin/TCF7L2 J. Integr. Agric. (IF 1.984) Pub Date : 2020-11-18 Ya-ni ZHANG; Cai HU; Ying-jie WANG; Qi-sheng ZUO; Bi-chun LI
Lin28A and Lin28B are homologous RNA-binding proteins that participate in the development of primordial germ cells. The mechanisms underlying expression and regulation of Lin28A have been well documented, but such information for Lin28B is limited. In this study, a fragment of the Lin28B promoter was cloned, the pEGFP-pLin28B vector was constructed. DF-1 chicken fibroblasts were transfected and the

The tissue expression level of BPI gene in piglets from newborn to weaning and its relationship with Gram-negative bacterial infection J. Integr. Agric. (IF 1.984) Pub Date : 2020-11-18 Chao-hui DAI; Yue CAO; Zhong-cheng GAO; Guo-qiang ZHU; Sheng-long WU; Wen-bin BAO
The bactericidal/permeability increasing protein (BPI) has an important function of nonspecific killing of Gram-negative bacteria. In this study, qPCR was used to detect the expression of the BPI gene in twelve tissues of Meishan piglets from birth to weaning. BPI gene overexpression, bacterial adhesions count and indirect immunofluorescence were applied to analyze the relationship between BPI gene

GraS is critical for chloroplast development and affects yield in rice J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Zhi-xuan DU; Hui-ying HAO; Jin-peng HE; Jian-ping WANG; Zhou HUANG; Jie XU; Hai-hui FU; Jun-ru FU; Hao-hua HE
Leaf color has been considered an important agronomic trait in rice (Oryza sativa L.) for a long time. The changes in leaf color affect the yield of rice. In this study, a green-revertible albino (graS) mutant was isolated from a 60Co-gamma-irradiated mutant pool of indica cultivar Guangzhan 63-4S. The fine mapping indicated that graS mutant was mapped to chromosome 1, and was located in a confined

The wheat receptor-like cytoplasmic kinase TaRLCK1B is required for host immune response to the necrotrophic pathogen Rhizoctonia cerealis J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Tian-ci WU; Xiu-liang ZHU; Liang-jie LÜ; Xi-yong CHEN; Gang-biao XU; Zeng-yan ZHANG
Receptor-like cytoplasmic kinases (RLCKs) represent a large family of proteins in plants. In Arabidopsis and rice, several RLCKs in subfamily VII (RLCKs-VII) have been implicated in pathogen-associated molecular pattern-triggered immunity and basal resistance against bacterial and fungal pathogens. However, little is known about roles of RLCKs-VII of the important crop common wheat (Triticum aestivum)

Grain proteomic analysis reveals central stress responsive proteins caused by wheat-Haynaldia villosa 6VS/6AL translocation J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Rong ZOU; Ji-su WU; Ruo-mei WANG; Yue-ming YAN
Haynaldia villosa (2n=14, VV), a wild grass of the subtribe Triticeae, serves as potential gene resources for wheat genetic improvement. In this study, the proteome characterization during grain development of Yangmai 5 and Yangmai 5-H. villosa 6VS/6AL translocation line was investigated by a comparative proteomic approach. Two-dimensional electrophoresis identified 81 differentially accumulated proteins

Morpho-physiological traits contributing to better yield performance of japonica/indica hybrids over indica hybrids under input-reduced practices J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Huan-he WEI; Tian-yao MENG; Jia-lin GE; Xu-bin ZHANG; Yu LU; Xin-yue LI; Yuan TAO; En-hao DING; Ying-long CHEN; Qi-gen DAI
It is widely reported that japonica/indica hybrids (JIH) have superior grain yield over other main varietal groups such as indica hybrids (IH) under sufficient resource inputs. To date, little attention has been paid to yield performance of JIH under input-reduced practices, and whether JIH could have better grain yield performance over IH under input-reduced practices. In this study, three JIH varieties

Growth, yield and water productivity of dry direct seeded rice and transplanted aromatic rice under different irrigation management regimes J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Muhammad ISHFAQ; Nadeem AKBAR; Shakeel Ahmed ANJUM; Muhammad ANWAR-IJL-HAQ
Sustainability of traditionally cultivated rice in the rice-wheat cropping zone (RWCZ) of Pakistan is dwindling due to the high cost of production, declining water resources and escalating labour availability. Thus, farmers and researchers are compelled to find promising alternatives to traditional transplanted rice (TPR). A field study was conducted in Punjab, Pakistan, in 2017 and 2018 to explore

Effects of post-heading high temperature on some quality traits of malt barley J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Sheng-jing NI; Hui-fang ZHAO; Guo-ping ZHANG
Global change is bringing barley with more frequency of suffering from high temperature. However, little has been known about the influence of high temperature on malt quality traits. In this study, we investigated the impact of 1-wk heat stress (32°C/26°C, day/night, 12 h/12 h) initiating from the 7th (HT7) and 14th (HT14) days after heading on some grain and malt quality traits of two barley cultivars

Kernel crack characteristics for X-ray computed microtomography (μCT) and their relationship with the breakage rate of maize varieties J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Peng-fei DONG; Rui-zhi XIE; Ke-ru WANG; Bo MING; Peng HOU; Jun-feng HOU; Jun XUE; Chao-hai LI; Shao-kun LI
The most significant problem of maize grain mechanical harvesting quality in China at present is the high grain breakage rate (BR). BR is often the key characteristic that is measured to select hybrids desirable for mechanical grain harvesting. However, conventional BR evaluation and measurement methods have challenges and limitations. Microstructural crack parameters evaluation of maize kernel is

Giving maize an excited start – Effects of dopamine on maize germination J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Hang-yuan CHENG; Xing WANG; Tian-yu FENG; Chuan-xi PENG; Wei WANG; Mu-yu YANG; Yu-yi ZHOU
Dopamine (DA) is a neurotransmitter which takes charge of brain activities about memory and self-stimulation behavior in animals. Interestingly, our results suggest that DA could also give maize an “excited state”. The results showed that 1 mmol L−1 DA promoted maize germination by 23.2% significantly, and accelerated the growth rate of roots and shoots by 21.4 and 24.7%, respectively. As we all known

Silencing the SLB3 transcription factor gene decreases drought stress tolerance in tomato J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Zi-yu WANG; Yu-fang BAO; Tong PEI; Tai-ru WU; Xu DU; Meng-xi HE; Yue WANG; Qi-feng LIU; Huan-huan YANG; Jing-bin JIANG; He ZHANG; Jing-fu LI; Ting-ting ZHAO; Xiang-yang XU
BRI1-EMS-SUPPRESSOR 1 (BES1) transcription factor is closely associated with the brassinosteroid (BR) signaling pathway and plays an important role in plant growth and development. SLB3 is a member of BES1 transcription factor family and its expression was previously shown to increase significantly in tomato seedlings under drought stress. In the present study, we used virus-induced gene silencing

The mitigation effects of exogenous dopamine on low nitrogen stress in Malus hupehensis J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Xiao-min LIU; Teng-teng GAO; Zhi-jun ZHANG; Ke-xin TAN; Yi-bo JIN; Yong-juan ZHAO; Feng-wang MA; Chao LI
Dopamine plays numerous physiological roles in plants. We explored its role in the regulation of growth, nutrient absorption, and response to nitrogen (N) deficiency in Malus hupehensis Rehd. Under low N condition, plant growth slowed, and the net photosynthetic rates, chlorophyll contents, and maximal quantum yield of PSII (Fv/Fm) decreased significantly. However, the application of 100 μmol L−1 exogenous

A novel glycoside hydrolase 74 xyloglucanase CvGH74A is a virulence factor in Coniella vitis J. Integr. Agric. (IF 1.984) Pub Date : 2020-10-14 Jia-xing QIN; Bao-hua LI; Shan-yue ZHOU
Grape white rot is a destructive fungal disease occurring worldwide. Recently, Coniella vitis was identified as the predominant pathogen causing this disease in China. As the periderms of grape shoots are severely degraded by C. vitis, it was speculated that cell wall-degrading enzymes (CWDEs) might play a key role in the pathogenesis of this disease. Therefore, this study aimed to examine the hydrolytic
