Study on Physical-Chemical Characters and Heritability for Yield Components in Rice (Oryza sativa L.).
Ngày đăng: 20/04/2017       Số lượt xem: 0
 

Present study was performed to analysis both physical and chemical properties of rice germplasm and heritability for yield components in combinations. A total of 44 line / varieties obtained from Cuu Long Rice Research Institute genebank, and 30 F1 generation combinations were evaluated.

Genetic Analysis of Teosinte Alleles for Kernel Composition Traits in Maize
Ngày đăng: 13/04/2017       Số lượt xem: 0
 

Teosinte (Zea mays ssp. parviglumis) is the wild ancestor of modern maize (Zea mays ssp. mays). Teosinte contains greater genetic diversity compared with maize inbreds and landraces, but its use is limited by insufficient genetic resources to evaluate its value.

Elevated rate of genome rearrangements in radiation-resistant bacteria

A number of bacterial, archaeal, and eukaryotic species are known for their resistance to ionizing radiation. One of the challenges these species face is a potent environmental source of DNA double-strand breaks, potential drivers of genome structure evolution.

BRASSINOSTEROID INSENSITIVE2 negatively regulates cellulose synthesis in Arabidopsis by phosphorylating cellulose synthase 1
Ngày đăng: 03/04/2017       Số lượt xem: 11
 

Cellulose is the most abundant biopolymer on Earth and is a critical component for plants to grow and develop. Cellulose is synthesized by large cellulose synthase complexes containing multiple cellulose synthase A (CESA) subunits; however, how cellulose synthesis is regulated remains unclear.

Molecular characterization and functional analysis of the OsPsbR gene family in rice

Low temperature may exert a negative impact on agronomical productivity. PsbR was known as the 10 kDa Photosystem II polypeptide. Although plant PsbR is thought to play important roles in photosynthesis, little is known about the contribution of plant PsbR to abiotic stress resistance.

Transgenerational epimutations induced by multi-generation drought imposition mediate rice plant`s adaptation to drought condition.

Epigenetic mechanisms are crucial mediators of appropriate plant reactions to adverse environments, but their involvement in long-term adaptation is less clear. Here, we established two rice epimutation accumulation lines by applying drought conditions to 11 successive generations of two rice varieties.

Effects of genetically modified maize events expressing Cry34Ab1, Cry35Ab1, Cry1F, and CP4 EPSPS proteins on arthropod complex food webs
Ngày đăng: 21/03/2017       Số lượt xem: 19
 

Four genetically modified (GM) maize (Zea mays L.) hybrids (coleopteran resistant, coleopteran and lepidopteran resistant, lepidopteran resistant and herbicide tolerant, coleopteran and herbicide tolerant) and its non-GM control maize stands were tested to compare the functional diversity of arthropods and to determine whether genetic modifications alter the structure of arthropods food webs.

Agrobacterium causes diseases in a wide range of host plants. It has been developed as a genetic tool to transform a variety of plant species and nonplant organisms. It can achieve a transformation efficiency as high as 100%.

Selective autophagy limits cauliflower mosaic virus infection by NBR1-mediated targeting of viral capsid protein and particles

Autophagy contributes to innate immune responses in metazoans by targeted elimination of intracellular pathogens, including viruses, in a process termed “xenophagy.” Whether autophagy has a similar role in plant immunity is unknown.

Marker-Combining Ability for 12 Yield-Related Traits in Oryza sativa L. subsp. Japonica.
Ngày đăng: 09/03/2017       Số lượt xem: 35
 

Heterosis or hybrid vigor is closely related with general combing ability (GCA) of parents and special combining ability (SCA) of combinations. The evaluation of GCA and SCA facilitate selection of parents and combinations in heterosis breeding. In order to improve combining ability (CA) by molecular marker assist selection, it is necessary to identify marker loci associated with the CA
