Susceptibility of the reproductive system to temperature fluctuations is a recurrent problem for crop production under changing climate. The damage complex as multiple processes in male and female gamete formation are affected, but general, particularly pollen impaired. Here, impact short periods elevated on meiosis tomato ( Solanum lycopersicon L.) reported. Meiocytes early stage flower buds e...

We examined the genetics of hybrid incompatibility between two closely related diploid hermaphroditic plant species. Using a set of near-isogenic lines (NILs) representing 85% of the genome of the wild species Lycopersicon hirsutum (Solanum habrochaites) in the genetic background of the cultivated tomato L. esculentum (S. lycopersicum), we found that hybrid pollen and seed infertility are each ...

The extended mind thesis holds that the mind can leak out into the world have offered a novel critique of this view by arguing that the question of cognitive extension is largely terminological or semantic, that it is a product of an immature science employing unhelpful metaphors about containment. They write, for instance: " We do not believe there is any basis for a general fact of the mater ...

large and diverse body of data argues that chromosomes are longitudinally A differentiated in such a way that corresponding segments located in different chromosomes are able to recognize and synapse with each other with a high degree of precision at meiotic prophase; this property is termed “homology.” Although regions exhibiting homology may not be coiitinuous throughout the length of a chrom...

We have synthesized diploid hybrids between Lycopersicon esculentum and Solanum lycopersicoides and have converted them to allotetraploids. Two sesquidiploids, having two complements of the former parent and one of the latter, have been obtained by backcrossing the former parent with the alloploid. In meiosis of the sesquidiploid the L. esculentum chromosomes exhibit strong preferential pairing...

L-ascorbate (the reduced form of vitamin C) participates in diverse biological processes including pathogen defence mechanisms, and the modulation of plant growth and morphology, and also acts as an enzyme cofactor and redox status indicator. One of its chief biological functions is as an antioxidant. L-ascorbate intake has been implicated in the prevention/alleviation of varied human ailments ...

Early blight of tomato (Solanum lycopersicon L.) incited by Alternaria solani is highly destructive disease in the world. Environmental factors significantly impact early epidemics, leading to loss up 78 per cent production. Twenty genotypes were used this study identify resistant and susceptible selected represent a range reactions when screened under field conditions. The plants evaluated for...

Calotropis proceran (Asclepidaceae) is an evergreen plant and widely distributed in Hormozgan province. This plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. In this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (Cucumis sativus), tomat...
