  • Symbiotic Relationships

    “It’s a tough world out there when you’re an herbivore, particularly for us insects.” I’m a Green Stinkbug (Nezara viridula). I’ll guide you through some of current battles between us and plants. These battles are constant, and have been on-going since the rise of the first plants and insects. This co-evolution process has developed symbiotic relationships- both good (commensalism) and bad (predation/parasitism) depending on whose side you’re on. The relationships we’ll see are between insects, plants, parasitoids (nasty things!) and occasionally humans. I will also clarify any misconceptions that have developed in the human world, you’ll know the real story. To begin, there are some details to know. Plants have deterrents and toxins in their structures, they developed structure that allow them to store these chemicals without damaging themselves. Some are constitutive (always there), and others are induced. Some constitutive chemicals are what make herbs and spices for humans, these are metabolic products their primary function is for defense. We will be focusing on both reactions. Over here, you’ll see the tragedy of the interaction between the fall armyworm (Spodoptera frugiperda) and bugleweed (Ajuga remota). These plants are capable of producing phytoecdysone. This is similar to ecdysteroids (or ecdysone) in insects. This hormone regulates our growth and molting development. Armyworms that ate this plant molted “from larvae to pupae, [and] each insect grew not one but…

    evolving. The genome of wheat and rye are different by 13 chromosomal rearrangements after only 6 million years of divergence (Devos). This rate is reshuffling is twice the average rate for nine taxa. Only Brassica-Arabidopsis lineage possesses a faster rate of reshuffling (Paterson). The Solanaceae The Solanaceae family includes a few economically important plant species such as tomato (Solanum lycopersicum), pepper (Capsicum annum), potato (S.tuberosum), eggplant (S.melongena) and tobacco…

  • Rubisco: A Genetic Analysis

    This can be explained by concerted evolution as a result of unequal crossover and gene conversions among gene copies. I examined gene conversion events among Angiosperms, and identified different patterns in different subfamilies. I detected simple duplication events followed by speciation in Solanaceae, loss of gene copies in Grass, and old gene duplication followed by independent gene conversions in different two clades of Brassicaceae. However, these observed gene conversion events differs…

  • Implications Of Tomato And Potato

    dehydrogenase activity of the soil and its activity is an indicator for microbial activity of the soil. Thus, soil fungi concentrate in the subsoil and play a major role in organic matter build up by decomposition and degradation of resistant organic component such as cellulose, lignin and chitin. They also participate in the stabilization of soil aggregates due to their filamentous nature and thus may prevent soil erosion (Banda et al., 2011). Therefore, soil amendments with organic materials…

  • Tomatoes Research Papers

    as a non-edible plant. After this stigma was overcome in the early 1700’s, tomatoes began to gain in popularity, with many new tomato recipes coming out around the 1880’s. It is thought that the first tomatoes must have been yellow, as Pomodoro (Italian for tomato) literally translates as golden apple. However, most varieties grown today are red. Tomatoes are red because they contain lycopene, an antioxidant compound which has been shown to be a powerful anti-carcinogen. They also contain a lot…

    1924), Convolvulus arvensis (Kennedy and Krafts 1931), in I. hederifolia (Lowell and Lucansky 1986), and in I. quamoclit (Lowell and Lucansky 1990). In Cressa cretica differentiation of internal phloem occurs adjacent to the inner side of the protoxylem, but does not differentiate against the xylem tissue in the younger internodes (Fig2A,C). Only phloem was produced internally and there was no outward production of xylem. Lowell and Lucansky (1986) had reported internal cambium in Ipomoea…
