In previous studies, we demonstrated cross-antagonism in pheromone perception between pheromone components of the two corn (Zea mays L.) borers Sesamia nonagrioides Lefèbvre (Lepidoptera: Noctuidae) and Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae) in the laboratory and in the field. The two pheromone components identified as responsible for this cross-antagonism were Z 11-16:Ald, a mino...

Cytogenetic evidence indicates that Zea, which comprises maize (Z. mays ssp. mays) and its wild relatives, is an allopolyploid genus. Our research group has carried out numerous cytogenetic studies on Zea species, mainly focused native Argentinian Bolivian landraces. We found a wide inter- intraspecific genome size variation in the genus, with mean 2C-values ranging between 4.20 11.36 pg. For l...

Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published sources for the period 1842-2016. A geographic...

Abstract—Selenium is an-antioxidant which is important for human health enters food chain through crops. In Kenya Zea mays is consumed by 96% of population hence is a cheap and convenient method to provide selenium to large number of population. Several soil factors are known to have antagonistic effects on selenium speciation hence the uptake by Zea mays. There are no studies in Kenya that has...

A soil contaminated by 10,000 ppm of gasoline (GAS), is a concentration higher than the limit 4,400 established Mexican standard NOM-138-SEMARNAT/SSA1-2003. In soil, it inhibits mineralization organic matter causing loss fertility. Therefore, aims this research a) biostimulation impacted GAS, and b) phytoremediation through Zea mays enhanced with Azotobacter vinelandii to decrease GAS value low...

Cytological diploidization process is different in autopolyploid and allopolyploid species. Colchicine applied at the onset of meiosis suppresses the effect of pairing regulator genes resulting multivalents formation in bivalent-forming species. Colchicine treated maizes (4x = 2n = 20, AmAmBmBm) showed up to 5IV, suggesting pairing between chromosomes from genomes homoeologous Am and Bm. In unt...

In the present study, Malaysian Zea mays hair extracts are screened for the occurrence of bioactive compounds. The results positively showed the present of flavonoids, saponin, tannins, phlobatannins, phenols, alkaloids and cardiac glycosides in both aqueous and methanolic extract of Zea mays hair. Terpenoid compounds however present only in the methanolic extract sample. In addition, the total...

Abstract Previous exploration has found that bee visitation tends to benefit yields of many pollinator-independent crops. However, the reverse this relationship—if crops bees—has not been extensively studied or explicitly reviewed. Therefore, we initiated a review literature using Web Science and EBSCOhost determine whether: 1) bees collect pollen from crops, 2) provided adequate nutrition for ...
