Cloning and expression analysis of rboh gene encoding respiratory burst oxidase in Citrullus colocynthis National Institute of Agronomic Research
Si, Y.; Kang, K.K.; Dane, F..
Drought stress is a major environmental factor influencing plant growth and development. Citrullus colocynthis is a very drought tolerant cucurbit species with a deep root system. Differences in gene expression during drought were studied using cDNA-AFLP. In this study, we focus on mRNA accumulation of drought-induced genes in C. colocynthis treated with PEG, abscisic acid (ABA), salicylic acid (SA), jasmonic acid (JA) or NaCl. Two genes, CcrbohD and CcrbohF, encoding respiratory burst oxidase proteins were cloned using RACE. Sequence comparison showed that the CcrbohD protein has a conserved region at the N terminus with an EF-hand loop domain, characteristic of the RBO protein family. Phylogenetic analysis confirmed that CcrbohD and CcrbohF belong to the...

Implications of the introgression between Citrullus colocynthis and C.lanatus characters in the taxonomy, evolutionary dynamics and breeding of watermelon. Repositório Alice
ASSIS, J. G. de A.; QUEIROZ, M. A. de; ARAUJO, S. M. C. de; BANDEL, G.; MARTINS, P. S..
Citrullus colocynthis is a wild species counted among the ancestors of the cultivated watermelon, C.lanatus. Cross-compatibility between species through both natural and artificial hybridization has been widely reported. Watermelon landraces were collected from the Northeast of Brazil and studies showed evidence of introgression from C. colocynthis to C. lanatus, although C.colocynthis is not distributed in Brazil. This paper discusses the implications of this introgression in the taxonomy, evolution dynamics and the improvement of watermelon.

Morphological characterization of Korean and Turkish watermelon germplasm National Institute of Agronomic Research
Huh, Y.C.; Solmaz, I.; Sari, N..
A total of 67 watermelon accessions of Korean (37 accessions) and Turkish (27 accessions) germplasm and 3 accessions of other species were characterized for morphological characteristics. The accessions were characterized according to UPOV descriptor list for 56 characters (6 seedling, 4 plant, 11 leaf, 5 flower, 23 fruit and 7 seed). Eight quantitative characters (hypocotyl length, cotyledon width, cotyledon length, fruit weight, fruit length, fruit width, thickness of outer layer of pericarp and soluble solid content) were also measured. According to the results of morphological characterization performed, the accessions displayed a large diversity; however, plant growth habit and leaf blade flecking were constant characters for all the accessions. The...

Reflections on linguistics as an aid to taxonomical identification of ancient Mediterranean cucurbits: the Piqqus of the Faqqous National Institute of Agronomic Research
Paris, H.S.; Janick, J..
There are a number of Mediterranean epithets for cucurbits that have intriguing connections in various ancient and modern languages. The most ancient and basic utterance is of Sumerian origin and includes a velar consonant (q, k) with a sibilant (s, sh, z). It is expressed in the Akkadian and Hebrew qishu and the Greek sikyos. The velar consonant without the sibilant is found in the Arabic qatta and doubled in the Greek kolokynthus and Latin cucumis and cucurbita. These and other possible linguistic implications and connections are considered with regard to cucurbit taxa of the ancient Mediterranean: Cucumis melo, Lagenaria siceraria, Citrullus lanatus, Citrullus colocynthis, and Ecballium elaterium.
