| 7 | Manipulation of SlMXl for enhanced carotenoids accumulation and drought resistance in tomato显示文摘Plants are the ultimate source of nutrients in the human diet. To ensure adequate availability of high quality food for an increasing world population, traits including improved tolerance of stresses and nutrient levels need to be selected in crops, both individually and in combination. Here we report the identification of Sl MX1 encoding a MIXTA-like MYB transcription factor in tomato that simultaneously modulates drought resistance and metabolic processes through regulating key structural and regulatory genes of the corresponding pathways. Over-expression of Sl MX1 results in substantially increased drought tolerance and improved fruit quality, while knocking down Sl MX1 resulted in the opposite phenotypes. Our study indicates an effective way with multiple beneficial traits by genetic engineering of a single regulatory gene and can be a novel approach to breeding crops. | Mohamed Ewas Yanqiang Gao Shouchuang Wang Xianqing Liu Hongyan Zhang Elsayed M.

| 8 | Crop diversity and pest management in sustainable agriculture显示文摘Large-scale crop monocultures facilitate the proliferation and increasing prevalence of diseases and pest insects.Many studies highlight the impacts of plant diversification upon pathogens,and the population dynamics of insects and beneficial organism in agricultural ecosystems.These studies provide evidence that habitat manipulation techniques such as intercropping,relay,and rotation can significantly improve disease and pest management.This review introduces the concept of crop diversity,considers recent insights and mechanisms underlying crop diversity,and discusses its potential for improving sustainable agricultural practices.Recently,the phytobiomes resulting from increased crop diversity are increasingly recognized for their contribution to disease and pest control.Further,understanding the interactions between pathogens or pests with their host phytobiome may lead to novel options for the prevention of pests.Recent advances in the agricultural systems include:(i)a better understanding of the mechanisms of interactions between crop species and genotypes;(ii)ecological progress including a better understanding of the context-dependency of those interactions;and(iii)the role of microtopographic variation in agricultural systems for priming basal resistance to multiple pests and pathogens by intercropped crops.We also highlight recent progress in China and the potential options for habitat management and design that enhance the ecological role of biodiversity in agroecosystems. | HE Han-ming LIU Li-na Shahzad Munir Nawaz Haider Bashir WANG Yi YANG Jing LI Cheng-yun | 2019 | Journal of Integrative Agriculture2019，18，9： | 8 |
| 9 | Saline-Alkali Tolerance in Rice: Physiological Response, Molecular Mechanism, and QTL Identification and Application to Breeding显示文摘Salinity-alkalinity is incipient abiotic stress that impairs plant growth and development.Rice(Oryza sativa)is a major food crop greatly affected by soil salinity and alkalinity,requiring tolerant varieties in the saline-alkali prone areas.Understanding the molecular and physiological mechanisms of saline-alkali tolerance paves the base for improving saline-alkali tolerance in rice and leads to progress in breeding.This review illustrated the physiological consequences,and molecular mechanisms especially signaling and function of regulating genes for saline-alkali tolerance in rice plants.We also discussed QTLs regarding saline-alkali tolerance accordingly and ways of deployment for improvement.More efforts are needed to identify and utilize the identified QTLs for saline-alkali tolerance in rice. | Ratan Kumar GANAPATI Shahzad Amir NAVEED Sundus ZAFAR WANG Wensheng XU Jianlong | 2022 | Rice science2022，29，5： | 8 |
| 10 | Per-oral endoscopic myotomy for achalasia: An American perspective显示文摘Achalasia is an uncommon esophageal motility disorder characterized by the selective loss of enteric neurons leading to absence of peristalsis and impaired relaxation of the lower esophageal sphincter.Per-oral endoscopic myotomy(POEM) is a novel modality for the treatment of achalasia performed by gastroenterologists and surgeons.It represents a natural orifice transluminal endoscopic surgery(NOTES) approach to Heller myotomy.POEM has the minimal invasiveness of an endoscopic procedure that can duplicate results of the surgical Heller myotomy.POEM is conceptually similar to a surgical myotomy without the inherent external incisions and post-operative care associated with surgery.Initial high success and low complications rates promise a great future for this technique.In fact,POEM has been successfully performed on patients with end-stage achalasia as an initial treatment reserving esophagectomy for those without good response.The volume of POEMs performed worldwide has grown exponentially.In fact,surgeons who have performed Heller myotomy have embraced POEM as the preferred intervention for achalasia.However,the niche of POEM remains to be defined and long term results are awaited.We describe our experience with POEM having performed the first POEM outside of Japan in 2009,the evolution of our technique,and give our perspective on its future. | David Friedel Rani Modayil Shahzad Iqbal James H Grendell Stavros N Stavropoulos | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，9： | 8 |
| 11 | Effects of uniconazole with or without micronutrient on the lignin biosynthesis,lodging resistance,and winter wheat production in semiarid regions显示文摘Lodging stress results in grain yield and quality reduction in wheat. Uniconazole, a potential plant growth regulator significantly enhances lignin biosynthesis and thus provides mechanical strength to plants in order to cope with lodging stress. A field study was conducted during the 2015–2016 and 2016–2017 growing seasons, to investigate the effects of uniconazole sole application or with micronutrient on the lignin biosynthesis, lodging resistance, and production of winter wheat. In the first experiment, uniconazole at concentrations of 0(CK), 15(US1), 30(US2), and 45(US3) mg L^-1 was applied as sole seed soaking, while in the second experiment with manganese(Mn) at concentration of 0.06 g L^-1 Mn, 0.06 g L^-1 Mn+ 15 mg L^-1 uniconazole(UMS1), 0.06 g L^-1 Mn+30 mg L^-1 uniconazole(UMS2), and 0.06 g L^-1 Mn+45 mg L^-1 uniconazole(UMS3), respectively. Uniconazole sole application or with micronutrient significantly increased the lignin content by improving the lignin-related enzyme activities of phenylalanine ammonia-lyase, cinnamyl alcohol dehydrogenase, tyrosine ammonialyase, and peroxidase, ameliorating basal internode characteristics, and breaking strength. The spike length, spike diameter, spikes/plant, weight/spike, yield/spike, and grain yield increased and then decreased with uniconazole application at a higher concentration, where their maximum values were recorded with UMS2 and US2 treatments. The lignin accumulation was positively correlated with lignin-related enzyme activities and breaking strength while, negatively correlated with lodging rate. Uniconazole significantly improved the lignin biosynthesis, lodging resistance, and grain yield of winter wheat and the treatments which showed the greatest effects were uniconazole seed soaking with micronutrient at a concentration of 30 mg L^-1 and 0.06 g L^-1 , and uniconazole sole seed soaking at a concentration of 30 mg L^-1 . | Irshad AHMAD MENG Xiang-ping Muhammad KAMRAN Shahzad ALI Shakeel AHMAD LIU Tie-ning CAI Tie HAN Qing-fang | 2020 | Journal of Integrative Agriculture2020，19，1： | 8 |

| 20 | Fluidization of nano and sub-micron powders using mechanical vibration显示文摘The fluidization behavior of nano and sub-micron powders belonging to group C of Geldart's classification was studied in a mechanically vibrated fiuidized bed(vibro-fiuidized bed) at room temperature. Pretreated air was used as the fiuidizing gas whereas SiO2,Al2O3,TiO2,ZrSi,BaSO4 were solid particles. Mechanical vibration amplitudes were 0.1,0.25,0.35,0.45 mm,while the frequencies were 5,20,30,40 Hz to investigate the effects of frequency and amplitude of mechanical vibration on minimum fiuidization velocity,bed pressure drop,bed expansion,and the agglomerate size and size distribution. A novel technique was employed to determine the apparent minimum fluidization velocity from pressure drop signals. Richardson-Zaki equation was employed as nano-particles showed fiuid like behavior when fiuidized. The average size of agglomerates formed on top of the bed was smaller than those at the bottom. Size distribution of agglomerates on top was also more uniform compared to those near the distributor. Larger agglomerates at the bottom of the bed formed a small fraction of the bed particles. Average size of submicron agglomerates decreased with increasing the frequency of vibration,however nano particles were less sensitive to change in vibration frequency. Mechanical vibration enhanced the quality of fluidization by reducing channeling and rat-holing phenomena caused by interparticle cohesive forces. | Souresh Kaliyaperumal Shahzad Barghi Lauren Briens Sohrab Rohani Jesse Zhu | 2011 | Particuology2011，9，3： | 6 |
