In an earlier work, we showed that if the Hodge conjecture holds for all complex abelian varieties of CM-type, then the Tate conjecture holds for all abelian varieties over finite fields (Milne 1999b). In this article, we extract from the proof a statement (Theorem 1.1) that sometimes allows one to deduce the Tate conjecture for the powers of a single abelian variety A over a finite field from ...

Calcium-dependent protein kinases (CDPKs) are molecular switches that bind Ca(2+), ATP, and protein substrates, acting as sensor relays and responders that convert Ca(2+) signals, created by developmental processes and environmental stresses, into phosphorylation events. The precise functions of the CDPKs in grapevine (Vitis vinifera) are largely unknown. We therefore investigated the phylogene...

Satsuma (Citrus unshiu Marc.) is one of the most abundantly produced mandarin varieties of citrus, known for its seedless fruit production and as a breeding parent of citrus. De novo assembly of the heterozygous diploid genome of Satsuma ("Miyagawa Wase") was conducted by a hybrid assembly approach using short-read sequences, three mate-pair libraries, and a long-read sequence of PacBio by the ...

consumers prefer seedless grapes for table and raisin grape industry. release of new superior seedless grape cultivars is one of the main objectives in grape breeding programs. embryo rescue is one of the techniques to develop a new seedless cultivar. therefore, in this study, the effects of bud flower spraying with ba (50 ppm) and ccc (200 ppm) before blooming were studied in ‘flame seedless’ ...

The influence of GA3 application on the fruit quality and productivity of cane pruned Thompson seedless was evaluated. Four treatments applied were: GA3, Girdle, GA3 + Girdle and control with no GA3 and no girdle were used. GA3 or GA3 + Girdle berries resulted in heavier berries, hastened berry diameter, and produced larger berries in comparison to the control grapevine trees. In addition, bunc...

Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties. The underlying mechanisms of 2n gamete formation were recently revealed for Citrus reticulata but remain poorly understood for other citrus species, including lemon (C. limon [L.] Burm. f.). Her...

Wang X., Cheng Z.-M., Zhi S., Xu F. (2016): Breeding triploid plants: a review. Czech J. Genet. Plant Breed., 52: 41–54. Triploid plants have larger organs, greater biomass, and strong stress resistance by preserving relatively larger amounts of photosynthetic energy. The undesirable spread of non-native invasive crop and horticultural plants into natural areas can also be reduced or eliminated...

As an incommensurate epitaxy, van der Waals epitaxy allows defect-free crystals to grow on substrates even with a large lattice mismatch. Furthermore, van der Waals epitaxy is proposed as a universal platform where heteroepitaxy can be achieved irrespective of the nature of the overlayer material and the method of crystallization. Here we demonstrate van der Waals epitaxy in solution phase synt...

Miniaturized accelerometers are necessary for evaluating the performance of small devices, such as haptics, robotics and simulators. In this study, we fabricated miniaturized accelerometers using well-aligned ZnO nanowires. The layer of ZnO nanowires is used for active piezoelectric layer of the accelerometer, and copper was chosen as a head mass. Seedless and refresh hydrothermal synthesis met...
