Breeding for drought stress toleranceSouth Asia Disaster Report: South Asia Disaster Report is a 2006 report by Duryog Nivaran, edited by Amjad Bhatti and others, and subtitled Tackling the Tides and Tremors. It looks at disasters affecting the South Asian region's "countries and communities (that) are connected to each other geologically, geographically and culturally".Phaseic acidOutline of water: The following outline is provided as an overview of and topical guide to water:Stoma: In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") (from Greek ["mouth"[http://www.perseus.Chronic cellular dehydrationSquamosa promoter binding protein: The SQUAMOSA promoter binding protein-like (SBP or SPL) family of transcription factors are defined by a plant-specific DNA-binding domain. The founding member of the family was identified based on its specific in vitro binding to the promoter of the snapdragon SQUAMOSA gene.Canna Leaf Roller: Cannas are largely free of pests, but in the USA plants sometimes fall victim the Canna Leaf Roller, which can actually be two different insects. Larva of the Brazilian skipper butterfly (Calpodes ethlius), also known as the Larger Canna Leaf Roller, cut the leaves and roll them over to live inside while pupating and eating the leaf.Plant perception (physiology): Plant perception is the ability of plants to sense and respond to the environment to adjust their morphology, physiology and phenotype accordingly. Other disciplines such as plant physiology, ecology and molecular biology are used to assess this ability.Maladaptation: A maladaptation () is a trait that is (or has become) more harmful than helpful, in contrast with an adaptation, which is more helpful than harmful. All organisms, from bacteria to humans, display maladaptive and adaptive traits.Weedy rice: Weedy rice, also known as red rice, is a variety of rice (Oryza) that produces far fewer grains per plant than cultivated rice and is therefore considered a pest. The name "weedy rice" is used for all types and variations of rice which show some characteristic features of cultivated rice and grow as weeds in commercial rice fields.Endodermis: The endodermis is the central, innermost layer of cortex in some land plants. It is made of compact living cells surrounded by an outer ring of endodermal cells that are impregnated with hydrophobic substances (Casparian Strip) to restrict apoplastic flow of water to the inside.Soil salinity control: Soil salinity control relates to controlling the problem of soil salinity and reclaiming salinized agricultural land.Photosynthesis: Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek [phōs, "light", and σύνθεσις], synthesis, "putting together".Acclimatization: Acclimatization (UK also acclimatisation; US also acclimation) is the process in which an individual organism adjusts to a gradual change in its environment (such as a change in temperature, humidity, photoperiod, or pH), allowing it to maintain performance across a range of environmental conditions. Acclimation occurs in a short period of time (days to weeks), and within the organism's lifetime (compare to adaptation).GAI (Arabidopsis thaliana gene)Desiccation tolerance: Desiccation tolerance refers to the ability of an organism to withstand or endure extreme dryness, or drought-like conditions. Plants and animals living in arid or periodically arid environments such as temporary streams or ponds may face the challenge of desiccation, therefore physiological or behavioral adaptations to withstand these periods are necessary to ensure survival.The Rain Rain Rain Came Down Down Down: "The Rain Rain Rain Came Down Down Down" is a narrative song from the Walt Disney musical film featurette, Winnie the Pooh and the Blustery Day. The song is also incorporated into the 1977 musical film The Many Adventures of Winnie the Pooh which is an amalgamation of three Winnie-the-Pooh featurettes including "Blustery Day".Chance seedling: A chance seedling is a plant that is the product of unintentional breeding. It may be a genetically unique individual with desirable characteristics that is then intentionally bred.Index of soil-related articles: This is an index of articles relating to soil.Peat swamp forest: Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat.Seedling: A seedling is a young plant sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed.Phacidiopycnis padwickii: Phacidiopycnis padwickii is a plant pathogen infecting chickpea.Hadley Centre for Climate Prediction and Research: 140px|rightPlant breeders' rights: Plant breeders' rights (PBR), also known as plant variety rights (PVR), are rights granted to the breeder of a new variety of plant that give the breeder exclusive control over the propagating material (including seed, cuttings, divisions, tissue culture) and harvested material (cut flowers, fruit, foliage) of a new variety for a number of years.Wheat middlings: Wheat middlings (also known as millfeed, wheat mill run, or wheat midds) is the middle of three grades into which flour and meal are classified: patents, middlings, and clears. Middlings are often used in animal feed.Leifsonia xyli xyli: Leifsonia xyli subsp. xyli is a small, fastidious, Gram-positive, coryneform bacterium that causes ratoon stunting disease, a major worldwide disease of sugarcane.VitexinKnudsen: Knudsen is a surname of Scandinavian origin, derived from the personal name Knud (Canute) and literally meaning "Knud's son."Halotolerance: Halotolerance is the adaptation of living organisms to conditions of high salinity.Walter Larcher, 2001 Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs.Water Agriculture and Health in Tropical Area: Water Agriculture and Health in Tropical Area (French, Eau Agriculture Et Sante Et Milieu Tropical (E.A.Imbibition: Imbibition is a special type of diffusion when water is absorbed by solids-colloids-causing them to enormously increase in volume. The classical examples of imbibition are absorption of water by seeds and dry wood.Xylem: Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The word xylem is derived from the Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout the plant.Tamarix aphylla: Tamarix aphylla is the largest known species of Tamarix (height: to18 metres—60 ft) . The species has a variety of common names, including Athel pine, Athel tree, Athel tamarisk, and saltcedar.Botryosphaeria corticola: Bot canker of oak is a disease on stems, branches and twigs of oak trees in Europe and North America. The casual agent of Bot canker of oak is the fungus Botryosphaeria corticola .EcosystemTomato seed oil: Tomato seed oil is a vegetable oil extracted from the seeds of tomatoes.Pith: 250px|right|thumb|[[Elderberry shoot cut longitudinally to show the broad, solid pith (rough-textured, white) inside the wood (smooth, yellow-tinged).

(1/754) DNA sequence variation and selection of tag single-nucleotide polymorphisms at candidate genes for drought-stress response in Pinus taeda L.

Genetic association studies are rapidly becoming the experimental approach of choice to dissect complex traits, including tolerance to drought stress, which is the most common cause of mortality and yield losses in forest trees. Optimization of association mapping requires knowledge of the patterns of nucleotide diversity and linkage disequilibrium and the selection of suitable polymorphisms for genotyping. Moreover, standard neutrality tests applied to DNA sequence variation data can be used to select candidate genes or amino acid sites that are putatively under selection for association mapping. In this article, we study the pattern of polymorphism of 18 candidate genes for drought-stress response in Pinus taeda L., an important tree crop. Data analyses based on a set of 21 putatively neutral nuclear microsatellites did not show population genetic structure or genomewide departures from neutrality. Candidate genes had moderate average nucleotide diversity at silent sites (pi(sil) = 0.00853), varying 100-fold among single genes. The level of within-gene LD was low, with an average pairwise r2 of 0.30, decaying rapidly from approximately 0.50 to approximately 0.20 at 800 bp. No apparent LD among genes was found. A selective sweep may have occurred at the early-response-to-drought-3 (erd3) gene, although population expansion can also explain our results and evidence for selection was not conclusive. One other gene, ccoaomt-1, a methylating enzyme involved in lignification, showed dimorphism (i.e., two highly divergent haplotype lineages at equal frequency), which is commonly associated with the long-term action of balancing selection. Finally, a set of haplotype-tagging SNPs (htSNPs) was selected. Using htSNPs, a reduction of genotyping effort of approximately 30-40%, while sampling most common allelic variants, can be gained in our ongoing association studies for drought tolerance in pine.  (+info)

(2/754) Mortality, recruitment and change of desert tree populations in a hyper-arid environment.

BACKGROUND: Long-term vegetation changes in hyper-arid areas have long been neglected. Mortality, recruitment and change in populations of the ecologically and culturally important and drought persistent Acacia tortilis and Balanites aegyptiaca are therefore estimated in the Eastern Desert of Egypt, and are related to the primary agents of change, water conditions and human intervention. METHODOLOGY: A change analysis using high-resolution Corona images (1965) in combination with field data (2003) is the basis for recruitment, mortality and change estimates. For assessing the influence of water conditions on patterns in recruitment and survival, different types of generalized linear models are tested. CONCLUSIONS: The overall trend in population size in that part of the Eastern Desert studied here is negative. At some sites this negative trend is alarming, because the reduction in mature trees is substantial (>50%) at the same time as recruitment is nearly absent. At a few sites there is a positive trend and better recruitment. Frequent observations of sprouting in saplings indicate that this is an important mechanism to increase their persistence. It is the establishment itself that seems to be the main challenge in the recruitment process. There are indications that hydrological variables and surface water in particular can explain some of the observed pattern in mortality, but our results indicate that direct human intervention, i.e., charcoal production, is the main cause of tree mortality in the Eastern Desert.  (+info)
