Saccharum Spp
A proposed model for the flowering signaling pathway of sugarcane under photoperiodic control
Authors: C.P. Coelho, A.P. Costa Netto, J. Colasanti and A. Chalfun-Junior
Molecular analysis of floral induction in Arabidopsis has identified several flowering time genes related to 4 response networks defined by the autonomous, gibberellin, photoperiod, and vernalization pathways. Although grass flowering processes include ancestral functions shared by both mono- and dicots, they have developed their own mechanisms to transmi.. Read More»

Selection in sugarcane based on inbreeding depression
Authors: A.A.C. de Azeredo, L.L. Bhering, B.P. Brasileiro, C.D. Cruz and M.H.P. Barbosa
This study aimed to evaluate the gene action associated with yield-related traits, including mean stalk weight (MSW), tons of sugarcane per hectare (TCH), and fiber content (FIB) in sugarcane. Moreover, the viability of individual reciprocal recurrent selection (RRSI-S1) was verified, and the effect of inbreeding depression on.. Read More»

Selfing rate estimation in sugarcane under unfavorable natural conditions of crossing by using microsatellite markers
Authors: M.L.G. Melloni , M.S. Scarpari, L.R. Pinto, D. Perecin, M.A. Xavier and M.G.A. Landell
The self-fertilization or selfing rate estimation using microsatellite markers and its impact on survival and selection rate were evaluated in families derived from polycrosses that involved parents that were widely used in sugarcane breeding in Brazil. These factors were evaluated under unfavorable natural conditions of flowe.. Read More»

Flow cytometry reliability analysis and variations in sugarcane DNA content
Authors: A.C.L. Oliveira, M. Pasqual, A.T. Bruzi, L.A.S. Pio, P.M.S. Mendon�§a and J.D.R. Soares
The aim of this study was to evaluate the reliability of flow cytometry analysis and the use of this technique to differentiate species and varieties of sugarcane (Saccharum spp) according to their relative DNA content. We analyzed 16 varieties and three species belonging to this genus. To determine a reliable protocol, we evaluated three extraction buffe.. Read More»

Differential gene expression in drought-tolerant sugarcane roots
Authors: J.S. Vantini, G.C. Dedemo, D.F. Jovino Gimenez, L.F.S. Fonseca, R.I.D. Tezza, M.A. Mutton, J.A. Ferro and M.I.T. Ferro
Drought is one of the most frequent abiotic stresses limiting the productivity and geographical distribution of sugarcane culture. The use of drought-tolerant genotypes is one approach for overcoming the effects of water stress. We conducted a comparative study to identify gene expression profiles under water stress in tolerant sugarcane roots. Two differ.. Read More»

Segregation analysis of microsatellite (SSR) markers in sugarcane polyploids
Authors: X. Lu, H. Zhou, Y.-B. Pan, C.Y. Chen, J.R. Zhu, P.H. Chen, Y.-R. Li, Q. Cai and R.K. Chen
No information is available on segregation analysis of DNA markers involving both pollen and self-progeny. Therefore, we used capillary electrophoresis- and fluorescence-based DNA fingerprinting together with single pollen collection and polymerase chain reaction (PCR) to investigate simple sequence repeat (SSR) marker segregation among 964 single pollens..
