Methods pPRV111A::neoSTLS2 construction and transplastomic plants pPRV111A::neoSTLS2 was produced by ligating the HindIII fragment containing neoSTLS2 from plasmid pCMneoSTLS2 (ref. 13) into pPRV111A. This transformation vector was introduced into the plastids of Nicotiana tabacum L. Petit Havana (N,N) by biolistic bombardment, and homoplasmic plants were regenerated as described previously. Th...

increasing of wood demand is currently one of the most important problems in our society. different clones of populus nigra from salicacea as a native fast-growing species have a good potential for planting in wide scale. but because of the ecological differences in the field, especially. temperature alterations, segregation of the cold resistant clones in relation to in seedling stage establis...

Stripe rust is a devastating disease in wheat that causes substantial yield loss around the world. The most effective strategy for mitigating to develop resistant cultivars. wild relatives of are good sources resistance fungal pathogens. Here, we used genome-wide association study (GWAS) identify loci associated with stripe (causal agent: Puccinia striiformis f. sp. tritici) emmer (Triticum dic...

A comprehensive germplasm evaluation study of wheat accessions conserved in the Indian National Genebank was conducted to identify sources of rust and spot blotch resistance. Genebank accessions comprising three species of wheat-Triticum aestivum, T. durum and T. dicoccum were screened sequentially at multiple disease hotspots, during the 2011-14 crop seasons, carrying only resistant accessions...

ABSTRACT One plant genotype displays a resistance phenotype at one development stage but a susceptible reaction to the same pathogen at another stage, which is referred to here as resistance inversion. In wheat, Fusarium head blight (FHB)-resistant cv. Sumai3 showed a Fusarium seedling blight (FSB)-susceptible reaction whereas FHB-susceptible cv. Annong8455 exhibited FSB resistance when challen...

Leaf rust (caused by Erikss. []) is increasingly impacting durum wheat ( L. var. ) production with the recent appearance of races with virulence to widely grown cultivars in many durum producing areas worldwide. A highly virulent race on durum wheat was recently detected in Kansas. This race may spread to the northern Great Plains, where most of the US durum wheat is produced. The objective of ...

Arabidopsis chotto1 (cho1) mutants show resistance to (-)-R-ABA, an ABA analog, during germination and seedling growth. Here, we report cloning and characterization of the CHO1 gene. cho1 mutants showed only subtle resistance to (+)-S-ABA during germination. The cho1 mutation acts as a strong enhancer of the abi5 mutant, whereas the cho1 abi4 double mutant showed ABA resistance similar to the a...

based studies are conducted, the effects of Al are usually confounded with other factors such as levels of P, Ca, Despite good resistance to acid-soil stresses, white clover (TriMo, Mn, Zn, organic acids, and other soil components folium repens L.) is not found on some acid soils. Our objectives (Edmeades et al., 1995; Villagarcia et al., 2001). An exwere to develop a large-leafed white clover ...

1. Physical defence traits of stems and leaves should enhance biomechanical strength and survival of seedlings. For eight neotropical tree species that differ widely in lifehistory strategies, we compared stem and leaf biomechanical traits of 1 and 7-monthold seedlings grown in the shaded forest understorey and in the laboratory. 2. Material traits (biomechanical traits per unit volume, mass or...
