Geometry applied to breeding common beans (Phaseolus vulgaris)
Authors: J.G. Lima and M.A.P. Ramalho
The primary components of common bean (Phaseolus vulgaris) grain yield (W) are the number of pods (X), the number of grains per pod (Y), and the weight of the grains (Z). In 1964, Grafius suggested using geometry in plant breeding; W corresponds to the volume of a parallelepiped with three axes, X, Y, and Z. Because the cube i.. Read More»

Bioinformatic and expression analysis of the OMT gene family in Pyrus bretschneideri cv. Dangshan Su
Authors: X. Cheng, Y. Xiong, D.H. Li, J. Cheng, Y.P. Cao, C.C. Yan, Q. Jin, N. Sun, Y.P. Cai and Y. Lin
With high nutritional value in its fruits, Dangshan Su pear has been widely cultivated in China. The stone cell content in fruits is a key factor affecting fruit quality in pear, and the formation of stone cells has been associated with lignin biosynthesis. O-Methyltransferase (OMT) is a key enzyme involved in lignin metabolism within the phenylpropanoid .. Read More»

Mixed inheritance in the genetic control of ramulosis (Colletotrichum gossypii var. cephalosporioides) resistance in cotton
Authors: M.A.C. Oliveira, J.B. Duarte, C.L. Morello, N.D. Suassuna and A.B. Oliveira
Ramulosis is one of the most aggressive diseases in cotton, and understanding the genetic control of its resistance is imperative for selecting superior cotton genotypes in breeding programs. This study analyzed the inheritance pattern of this resistance using chi-square goodness-of-fit tests to determine the phenotypic proportions of the F2 generation, and .. Read More»

Functional analysis of a TGA factor-binding site located in the promoter region controlling salicylic acid-induced NIMIN-1 expression in Arabidopsis
Authors: J.P. Fonseca, M. Menossi, F. Thibaud-Nissen and C.D. Town
TGA factors play a key role in plant defense by binding to the promoter region of defense genes, inducing expression. Salicylic acid (SA) induces the expression of the gene encoding NIMIN-1, which interacts with NPR1/NIM1, a key regulator of systemic acquired resistance. We investigated whether the TGA2-binding motif TGACG located upstream of the NIMIN-1 .. Read More»

A rapid method for isolation of total DNA from pathogenic filamentous plant fungi
Authors: D. GonzÃ?¡lez-Mendoza, R. Argumedo-Delira, A. Morales-Trejo, A. Pulido-Herrera, L. Cervantes-DÃ?Âaz, O. Grimaldo-Juarez and A. AlarcÃ?³n
DNA isolation from some fungal organisms of agronomic importance is difficult because they have cell walls or capsules that are relatively unsusceptible to lysis. We have developed a fast DNA isolation protocol for Fusarium oxysporum, which causes fusarium wilt disease in more than 100 plant species, and for Pyrenochaeta terre.. Read More»

Chemical and genetic diversity of high-seed-yield sorghum (Sorghum bicolor M.) germplasms
Authors: J. Ryu, S.B. Im, S.J. Kwon, J.W. Ahn, S.W. Jeong and S.Y. Kang
This study evaluated the chemical and genetic diversity of high-seed-yield sorghum germplasms from Korea, the United States, and South Africa. We identified significant differences in the chemical contents of whole plants at the heading stage in all cultivars, including differences in crude protein, fat, fiber, ash, neutral de.. Read More»

Selection index based on the relative importance of traits and possibilities in breeding popcorn
Authors: R.A. Vieira, R. Rocha, C.A. Scapim, A.T. Amaral J�ºnior and M. Vivas
One of the major difficulties faced by popcorn breeders is the negative correlation between popping expansion (PE) and grain yield (GY). It is necessary to overcome this difficulty to obtain promising genotypes. One helpful tool in this process is a selection index because it allows multiple features of interest to be selected..

Genetic improvement of plant architecture in the common bean
Authors: V.M.P. Silva, J.A.N. Menezes J�ºnior, P.C.S. Carneiro2, J.E.S. Carneiro and C.D. Cruz
Knowledge of genetic control of plant architecture in the common bean can help breeders define the most adequate breeding strategy to optimize gains. We examined genetic control of plant architecture in the common bean by means of partial diallel crosses. Fourteen bean lines were crossed under a partial diallel scheme, in which group 1 was composed of 8 e.. Read More»

Genetic variability in domesticated Capsicum spp as assessed by morphological and agronomic data in mixed statistical analysis
Authors: C.P. Sudr�©, L.S.A. Gon�§alves, R. Rodrigues, A.T. do Amaral J�ºnior, E.M. Riva-Souza and C. dos S. Bento
Capsicum species are very important in Brazil because of economic, cultural and biological factors, and the country is considered to be a diversity center for this genus. Collection and maintenance of the genetic diversity in Capsicum are important to avoid genetic erosion. Besides the identification of species, the characteri.. Read More»
