the phenotypic diversity of potato, solanum tuberosum was assessed using morphological traits. to verify, how this diversity is distributed among the main potato varieties in the growing areas in iran. a total of eleven potato varieties, ramose, sante, shepody, marfona, maradona, milova, santana, boren, cosima, granola and agria, were evaluated under vivo and situ experimental conditions in isf...

Studying of climatic elements  are one of the most important factors   influencing on agricultural crops  production and developing of agriculture activities in every region that led to increasing production . by studying of agro climatology  can be determined potential facilities in different areas  and used optimum of  facilities . this research was established  by determining  temperature po...

Global temperature has increased by 0.85 • C between 1880 and 2012, with an acceleration during the last decades and many extreme weather events since about 1950 (IPCC, 2014). A consequence already observed is the change of species distributions. Thermal requirements and constraints are key factors in shaping realized distributions, and climate warming may move or remove these distributional ba...

Background Allergy to tomato (Lycopersicon esculentum) has been reported to occur in 3-16% of food allergic subjects. Tomato allergy is frequently manifested as OAS, urticaria and gastrointestinal symptoms. So far, three tomato allergens, Lyc e 1 (profilin), Lyc e 2 (invertase) and Lyc e 3 (nsLTP) are listed in the official IUIS allergen database. Although tomato allergy is frequently associate...

Problem statement: Dried tomato pomace may be considered as an alternative feedstuff in ruminant nutrition. The limited literature data that are available so far may be interpreted as indirect and suggestive evidence for diminished ruminal fermentation and bacterial synthesis after substitution of dried tomato pomace for soybean meal. Approach: Rumen-fistulated beef steers were used to address ...

Resistance of tomato plants to the bacterial pathogen Pseudomonas syringae pv. tomato race 0 is controlled by the locus Pto. A bacterial avirulence gene was cloned by constructing a cosmid library from an avirulent P. syringae pv. tomato race, conjugating the recombinants into a strain of P. syringae pv. maculicola virulent on a tomato cultivar containing Pto, and screening for those clones tha...

ABSTRACT Sixty Ecuadorian isolates of Phytophthora infestans from potato and 60 isolates from tomato were compared for dilocus allozyme genotype, mitochondrial DNA haplotype, mating type, and specific virulence on 11 potato R-gene differential plants and four tomato cultivars, two of which contained different Ph genes. Restriction fragment length polymorphism (RFLP) fingerprints of subsamples o...

Increasing availability and extent of biological ocean time series (from both in situ and satellite data) have helped reveal significant phenological variability of marine plankton. The extent to which the range of this variability is modified as a result of climate change is of obvious importance. Here we summarize recent research results on phenology of both phytoplankton and zooplankton. We ...

We analyzed the phenology of Ficus adhatodifolia Schott ex Spreng. (23 fig tree) and F. eximia Schott (12 fig tree) for 74 months in a remnant of seasonal semi-deciduous forest (23° 27'S and 51° 15'W), Southern Brazil and discussed their importance to frugivorous. Leaf drop, leaf flush, syconia production and dispersal were recorded. These phenophases occurred year-round, but seasonal peaks wer...

BACKGROUND It has been shown that a large variation is present and exploitable from wild Solanum species but most of it is still untapped. Considering the thousands of Solanum accessions in different gene banks and probably even more that are still untouched in the Andes, it is a challenge to exploit the diversity of tomato. What have we gained from tomato domestication and breeding and what ca...
