A novel cDNA clone encoding a putative EIN3-like protein (LeEIL4) was identified from ripening tomato (Lycopersicon esculentum) fruit. The predicted amino acid sequence contained conserved domains of EIN3-like proteins in the N-terminal half. In phylogenetic analysis, LeEIL4 was classified into the cluster consisting of EIN3 and EIN3-like proteins known to be involved in ethylene signal transdu...

Conversion of the spirosolane-type glycoside, esculeoside A, a major component contained in the ripe tomato Lycopersicon esculentum fruits, into a solanocapsine-type sapogenol, esculeogenin B-2, (5alpha,22S,23R,25S)-22,26-epimino-16beta,23-epoxy-3beta,23,27-trihydroxycholestane, and esculeogenin B-1, (5alpha,22R,23S,25S)-22,26-epimino-16beta,23-epoxy-3beta,23,27-trihydroxycholestane, which are ...

Cilj istraživanja bio je utvrditi alelopatski potencijal lucerne (Medicago sativa L.) na klijavost sjemena i rast klijanaca rotkvice (Raphanus sativus L.), radiča (Cichorium intybus L. var. foliosum) rajčice (Lycopersicon esculentum Mill.). Vodeni ekstrakti pripremljeni od suhe nadzemne mase u tri koncentracije (1 %, 2,5 % 5 %) testirani su laboratorijskim uvjetima. Alelopatski ovisio o test vr...

As one of the edible jellyfish species, Rhopilema esculentum (Kishinouye, 1891) is a traditional fishery resource and an important economic aquaculture species in China. However, facing current situation natural resources exhaustion problems breeding population frequent disease, quantity, quality seedlings artificial cannot satisfy market demand. Temperature salinity have been considered to pla...

*Part of the dissertation necessary for the M.Sc. degree in Plant Pathology of the first author, Universidade de Brasília (2002). CAPES fellowship Determination of virus diversity in the field is vital to support a sustainable breeding program for virus resistance of horticultural crops. The present study aimed to characterize four field potyvirus isolates found naturally infecting sweet pepper...

Naturally occurring variation in wild species can be used to increase the genetic diversity of cultivated crops and improve agronomic value. Populations of introgression lines carrying wild species alleles afford an opportunity to identify traits associated with the introgressed regions, and facilitate characterization of the biochemistry and genetics underlying these phenotypes. Understanding ...

HsfA2 is a heat stress (hs)-induced Hsf in peruvian tomato (Lycopersicon peruvianum) and the cultivated form Lycopersicon esculentum. Due to the high activator potential and the continued accumulation during repeated cycles of heat stress and recovery, HsfA2 becomes a dominant Hsf in thermotolerant cells. The formation of heterooligomeric complexes with HsfA1 leads to nuclear retention and enha...

Heterostyly is thought to have evolved because it confers efficiency of cross-pollination. While it can be an alternative to an incompatibility mechanism in tube-shaped flowers, its effectiveness in dish-shaped flowers, such as those of Fagopyrum esculentum, has not been demonstrated. Stigmatic pollen loads were examined over the daily course of pollination in a planted field of this crop speci...

HE red color of the cultivated tomato, Lycopersicon esculentum Mill. is due to T the carotenoid lycopene. LEROSEN et al. (1941) and ZECHMEISTER et al. (1941) first analyzed the carotenoids of yellow (rr) and tangerine (tt) strains, each of which differs from the red by a single recessive gene. MACKINNEY and JENKINS (1952), JENKINS and MACKINNEY (1953), and TOMES et al. (1953) have examined the ...
