Overexpression of a constitutively active truncated form of OsCDPK1 (OEtr) in rice produced smaller seeds, but a double-stranded RNA gene-silenced form of OsCDPK1 (Ri) yielded larger seeds, suggesting that OsCDPK1 plays a functional role in rice seed development. In the study presented here, we propose a model in which OsCDPK1 plays key roles in negatively controlling the grain size, amylose content, and endosperm appearance, and also affects the physicochemical properties of the starch

Synchytrium endobioticum causes potato wart disease imposing severe losses in potato production, and as a quarantine pathogen in many countries, it results in lost trade markets and land for potato cultivation. The resistance to S. endobioticum pathotype 1(D1) is widespread in potato cultivars but new virulent pathotypes appear and the problem re-emerges. To characterize and map a new gene for resistance to potato wart, we used diploid F1 potato population from a cross of potato clone resistant to S. endobioticum pathotype 1(D1) and virulent pathotypes:

Gibberellin (GA) is a plant hormone that regulates important growth processes including germination, flowering, and fruit development. DELLA proteins inhibit GA responses. GA signaling increases through GA triggered destruction of the DELLA protein. Several mutants with reduced stature due to mutations that stabilize the DELLA protein are known. Many of these mutations cause deletions within the DELLA domain.

CRISPR-Cas systems provide microbes with adaptive immunity to infectious nucleic acids and are widely employed as genome editing tools. These tools utilize RNA-guided Cas proteins whose large size (950–1400 amino acids) has been considered essential to their specific DNA- or RNA-targeting activities. Here we present a set of CRISPR-Cas systems from uncultivated archaea that contain Cas14, a family of exceptionally compact RNA-guided nucleases (400–700 amino acids).

Sucrose transporters (SUT) play crucial roles in wheat stem water soluble carbohydrate (WSC) remobilization to grain. To determine the major functional SUT gene groups in shoot parts of wheat during grain development, drought tolerant varieties, Westonia and Kauz, were investigated in field drought experiments. Fourteen homologous genes to OsSUT1-5 were identified on five homeologous groups,

Salinity stress is a major limitation to rice (Oryza sativa L.) yields and its stability, especially in the Mekong delta, Vietnam. The purpose of this experiment was to develop rice varieties tolerant to salinity on the basis of molecular markers.Two hundred fifty three BC2F2 rice lines of the OM7347/OM5629 were evaluated at seedling stage in the green house of CLRRI. Molecular markers associated with salt tolerance QTLs were identified by using 416 polymorphic SSR markers.

Histone deacetylases (HDACs) function as key epigenetic factors in repressing the expression of genes in multiple aspects of plant growth, development and plant response to abiotic or biotic stresses. To date, the molecular function of HDACs is well described in Arabidopsis thaliana, but no systematic analysis of this gene family in soybean (Glycine max) has been reported.

When developing CRISPR/Cas9 systems for crops, it is crucial to invest time characterizing the genome editing efficiency of the CRISPR/Cas9 cassettes, especially if the transformation system is difficult or time-consuming. Cotton is an important crop for the production of fiber, oil, and biofuel. However, the cotton stable transformation is usually performed

The succinate dehydrogenase inhibitor (SDHI) fungicide, fluopyram, is used as a soybean seed treatment to manage Fusarium virguliforme, the casual agent of sudden death syndrome (SDS). More recently, other species within clade 2 of the Fusarium solani species, F. tucumaniaein South America and F. brasiliense in America and Africa, have been recognized as additional agents capable of causing SDS. To determine if fluopyram could be used for management of SDS caused by these species, in vitro sensitivity tests of the three Fusarium species to fluopyram were conducted.

Current breeding relies mostly on random mutagenesis and recombination to generate novel genetic variation. However, targeted genome editing is becoming an increasingly important tool for precise plant breeding. Using the CRISPR‐Cas system combined with the bean yellow dwarf virus rolling circle replicon, we optimized a method for targeted mutagenesis and gene replacement in tomato.
