Elucidating the relationships between gene expression and the physiological mechanisms remains a bottleneck in breeding for resistance to salinity and drought. This study related the expression of key target genes with the physiological performance of durum wheat under different combinations of salinity and irrigation. The candidate genes assayed included two encoding for the DREB（dehydration responsive element binding） transcription factors Ta DREB1 A and Ta DREB2 B, another two for the cytosolic and plastidic glutamine synthetase（Ta GS1 and Ta GS2）, and one for the specific Na^＋/H^＋ vacuolar antiporter（Ta NHX1）. Expression of these genes was related to growth and different trait indicators of nitrogen metabolism（nitrogen content, stable nitrogen isotope composition, and glutamine synthetase and nitrate reductase activities）, photosynthetic carbon metabolism（stable carbon isotope composition and different gas exchange traits） and ion accumulation. Significant interaction between genotype and growing conditions occurred for growth, nitrogen content, and the expression of most *** general terms, higher expression of Ta GS1, Ta GS2,Ta DREB2 B, and to a lesser extent of Ta NHX1 were associated with a better genotypic performance in growth, nitrogen, and carbon photosynthetic metabolism under salinity and water stress. However, Ta DREB1 A was increased in expression under stress compared with control conditions, with tolerant genotypes exhibiting lower expression than susceptible ones.

Journal of Integrative Plant Biology 2012年第12期54卷 1007-1020页

To increase maize （Zea mays L.） yields in drought-prone environments and offset predicted maize yield losses under future climates, the development of improved breeding pipelines using a multi-disciplinary approach is essential. Elucidating key growth processes will provide opportunities to improve drought breeding progress through the identification of key phenotypic traits, ideotypes, and donors. In this study, we tested a large set of tropical and subtropical maize inbreds and single cross hybrids under reproductive stage drought stress and well-watered conditions. Patterns of biomass production, senescence, and plant water status were measured throughout the crop cycle. Under drought stress, early biomass production prior to anthesis was important for inbred yield, while delayed senescence was important for hybrid yield. Under well-watered conditions, the ability to maintain a high biomass throughout the growing cycle was crucial for inbred yield, while a stay-green pattern was important for hybrid yield. While new quantitative phenotyping tools such as spectral reflectance （Normalized Difference Vegetation Index, NDVI） allowed for the characterization of growth and senescence patterns as well as yield, qualitative measurements of canopy senescence were also found to be associated with grain yield.

Multitemporal landslide inventory analysis of an intertropical mountain in west-central Mexico——Basis for hazard management

引用

Journal of Mountain Science 2022年第6期19卷 1650-1669页

作者： Alejandro Cesar VALDES CARRERA Manuel E.MENDOZA Teodoro CARLÓN ALLENDE jose luis MACIAS Centro de Investigaciones en Geografia Ambiental Universidad Nacional Autonoma de MexicoMorelia 58190Mexico Consejo Nacional de Ciencia y Tecnologia-Instituto de Geofisica-Unidad Michoacan Universidad Nacional Autonoma de MexicoMorelia 58190Mexico Instituto de Geofisica-Unidad Michoacan Universidad Nacional Autonoma de MexicoMorelia 58190Mexico

Landslides in intertropical mountainous areas of Mexico are a natural hazard that could potentially generate a disaster. Despite this, many areas lack landslide inventories, making it difficult to monitor and efficiently manage the associated risks for local populations. For this reason, the aim of this research was to undertake a multitemporal landslide inventory and analyze its conditioning factors in the Pico de Tancítaro stratovolcano, which, in recent decades, has presented several high-risk geomorphological events with disastrous consequences for nearby localities. The spatial distribution of landslides and its conditioning factors were mapped at a 1:50,000 scale for the 1995-2020 period, through visual interpretation of orthophotos and satellite images(Landsat, SPOT, and SENTINEL). The conditioning factors that link the most to landslides were Quaternary andesite and basaltic andesite rocks;volcanic cones, mountain river valleys, and very steep to steep slopes(30° to >45°), oriented to the South, North, and East;Andosols and Leptosols;and the oyamel fir and mixed forests. 505 landslide events classified into slides and flows that occurred in 1995, 2004, 2010, and 2015 were identified. New scars generated by the reactivation of landslide processes were also observed. The landslides in the study area were triggered by torrential rains caused by hurricanes and tropical storms;such as hurricanes Alex and Patricia. The inventory and analysis of conditioning factors highlighted the distribution and dynamics of slides and flows in the study area. In addition, the most important factors for studies of landslide susceptibility, hazards, and risks in the Pico de Tancítaro stratovolcano were identified, contributing to the management of geomorphological risks in intertropical mountain areas.

Molecular Plant 2018年第10期11卷 1222-1224页

作者： Riad Nadi Eduardo Mateo-Bonmati Lucia Juan-Vicente jose luis Micol Instituto de Bioingenieria Universidad Miguel Hern&ndez Campus de Elche 03202 Elche Spain

The 2-oxoglutarate and Fe （ll）-dependent dioxygenase （2OGD） superfamily includes oxidative enzymes with an active site con- taining two histidines and （in most cases） one aspartic or glutamic acid residue. This conserved motif is termed the 2-His-1-carboxylate facial triad, chelates iron, and is housed within a double-stranded β-helix fold, also known as the DSBH, jelly-roll, cupin, or Jumonji C fold （Martinez and Hausinger, 2015）. The reactions catalyzed by 2OGDs （also called 2ODDs, 2ODQs, and 2OGXs） include but are not limited to demethylation, demethylenation, hydroxytation, halogenation, desaturation, ring cleavage, ring closure, and epimerization （Farrow and Facchini, 2014）.

MULTISTEP METHODS FOR A CLASS OF HIGHER ORDER DIFFERENTIAL PROBLEMS:CONVERCENCE AND ERROR BOUNDS

引用

Journal of Computational Mathematics 1994年第3期12卷 273-290页

作者： Lucas jodar jose luis Morera GregorioRubio(Department of Applied Mathematics, Polytechnical University of Valencia, Spain) Polytechnical University of Valencia 西班牙

In this paper multistep methods for higher order dtherential systems of the type Y(r) = f(t, Y) are proposed. Such methods permit the numerical solutions of initial value problems for such systems, providing error bounds and avoiding the increase of the computational cost derived from the standard approach based on the collsideration of an equivalent extended first order system.
