We report the nucleotide sequence of a gene encoding the c ('16 kDa') subunit of the vacuolar-type H+-ATPase (V-ATPase) from a marine red alga, Porphyra yezoensis. A cDNA clone was isolated from a leafy gametophyte cDNA library and analyzed for the sequence. The genomic DNA sequence was directly determined by nested PCR. The structural gene contained four introns within a coding sequence of 483...

The LEAFY/FLORICAULA genes from Arabidopsis and Antirrhinum are necessary for normal flower development and play a key role in diverse angiosperm species. A homologue of these flower meristem-identity genes, NEEDLY (NLY), has been identified in Pinus radiata. Although the NLY protein shares extensive sequence similarity with its angiosperm counterparts, it is lacking the proline-rich and acidic...

Variation in plant shoot structure may be described as occurring through changes within a basic unit, the metamer. Using this terminology, the apical meristem of Arabidopsis produces three metameric types sequentially: type 1, rosette; type 2, coflorescence-bearing with bract; and type 3, flower-bearing without bract. We describe a mutant of Arabidopsis, Leafy, homozygous for a recessive allele...

Assessment of vitamin K (VK) dietary intakes has been limited by incomplete VK food composition data for the US food supply. The phylloquinone (VK-1 or vitamin K1) concentrations of a variety of geographically representative vegetables (n 1⁄4 218) were determined by reversed-phase high performance liquid chromatography with fluorescent detection. Green leafy and flower vegetables including broc...

objectives: ticks are vectors of several diseases, of which many are zoonosis transmissible to humans. the use of tephrosia leafs’ extract as a low cost acaricide is spreading among farmers in central kenya. materials and methods: the present study’s aim is to inventory endogenous control methods against dogs’ ticks among which rhipicephalus sanguineus, in the municipality of abomey-calavi. fro...

Rocket is an important leafy vegetable crop and a good source of antioxidants and anticancer molecules such as glucosinolates and other sulfur compounds. Rocket is also a hyper-accumulator of nitrates which have been considered for long time the main factors that cause gastro-intestinal cancer. In this review, the content of these compounds in rocket tissues and their levels at harvest and duri...
