Chromosome-specific painting is a powerful technique in molecular cytogenetic and genome research. We developed an oligonucleotide (oligo)-based chromosome painting technique in cucumber (Cucumis sativus) that will be applicable in any plant species with a sequenced genome. Oligos specific to a single chromosome of cucumber were identified using a newly developed bioinformatic pipeline and then...

Although we have made great progress in developing resistance to root – knot nematodes in cucumber, no source has been created or screened to resistance to M. incognita, the main species affecting cucumber (9, 10). Resistance to M. incognita exists in horned cucumber (Cucumis metuliferus), but efforts by many research groups (including our own) to make crosses of Cucumis species with cucumber h...

DINUROTHRIPS HOOKERI HOOD (THYSANOPTERA: THRIPIDAE: PANCHAETOTHRIPINAE): UN NUEVO RÉCORD PARA CUCUMIS SATIVUS EN PUERTO RICO

Chloroplast structure and function is known to alter during foliar senescence. Besides, the alterations in the structural organisation of thylakoid membranes changes in the steady state levels of thylakoid membrane proteins occur due to leaf ageing. We monitored temporal changes in some of the specific proteins of thylakoid membrane protein complexes by western blotting in the Cucumis sativus c...

In North Carolina, approximately 8% of the cucumber (Cucumis sativus) yield is lost to root-knot nematodes (Meloidogyne spp.) (Main and Gurtz, 1989). No resistance was found in cucumber after screening of 900 cultigens for resistance to Meloidogyne incognita race 3 (Walters, 1991). African horned cucumber (Cucumis metuliferus) has resistance to M. incognita (Fassuliotis, 1967; Walters, 1991), a...

Cucumis melo Linn. (Cucurbitaceae) fruits have been used, traditionally, for the treatment of various disorders of heart as Cardioprotective and antiobesity. The aim of the present study was to investigate the possible anti-hyperlipidemic activity of Cucumis melo fruit peel extract in triton induced hyperlipidemia in rats. Chloroform, Methanolic and aqueous extracts of were administered to the ...

In August 1946, marked viruslike symptoms were observed on watermelon {Citrullus vulgaris Schrad.) and muskmelon (Cucumis melo L.) plants in a field at Merrimac, Wis. Inoculations from infected plants to tobacco (Nicotiana tabacum L.), cucumber (Cucumis sativus i.)> ö.nd watermelon demonstrated that the disease was of virus origin. Isolates from watermelon and muskmelon were identical, and one ...

Root growth of Cucumis and Avena seedlings is inhibited by volatile materials produced by leaves of Salvia leucophylla, S. apiana, and Artemisia californica. The toxic substance may be deposited when dew condenses on affected seedlings in the field.

The major spiroacetal ((E,E)-1) of the pestiferous fruit flies, Bactrocera tryoni and Bactrocera cucumis, is biosynthesised from fatty acids by distinguishable pathways which utilise modified beta-oxidation and C-H hydroxylation, generating a putative ketodiol which cyclises.
