Fragrance in rice is a culturally and economically significant trait in Asia and around the world. This study aimed to develop a genetic and geographic profile of the fragrance-associated BADH2 mutations (badh2.1 and badh2.11) in 1,067 rice varieties from China, Laos, and Vietnam, which are part of the International Rice Genebank Collection. Seventy-three varieties were found to carry the common eight-base pair (bp) deletion in exon 7 of the genes (badh2.1, also known as badh2.7), primarily from indica varieties, with some belonging to japonica, javanica, and intermediate varieties. Conversely, 59 varieties possess the recently identified badh2 allele, badh2.11 (also known …

There is a huge demand for coffee in the Philippines but local supply has a long way to go at catching up. One way to aid local farmers is to develop coffee varieties with combined desirable traits including natural resistance against various diseases and insect pests. This can increase product output and reduce costs on chemical control that can, in turn, potentially increase their profits. This paper reviews and gives an overview of the genetic research on coffee toward improving plant defense. The most prominent diseases and pests plaguing plantations worldwide are noted. From studies using classical tools such as …
Molecular Mimicry Of Noda Genes By An N-Acetylmuramoyl-L-Alanine Amidases Gene In A Nodule Forming Staphylococcus Cohnii [Research Note], Aberathne Herath Mudiyanselage Nadeeshani Ruwandika Aberathne, Wedage Methsala Madurangi Wedage, Dilantha Gunawardana

A rare, nodule-forming, Gram-positive bacterium (Sub4) was isolated from the forage and cover crop Pueraria phaseoloides, which aligned at 99.26% sequence identity to a partial 16S rDNA sequence of Staphylococcus cohnii sp. This was the first record of a strain/species of Staphylococcus capable of independent, unassisted nodule formation in a legume host. When a nodA gene was sought by PCR using a pair of gene-specific primers synthesized using a related (Firmicutes) Paenibacillus sp. nodA gene, the reaction yielded a PCR product of similar size but a distinct identity. The resulting ~400bp PCR product coded for a likely N-acetylmuramoyl-L-alanine amidase …

Healthy foodstuffs, including functional foods, are the key component of a healthy and prosperous life. Oat grains are rich in protein, soluble dietary fiber, β-glucan, starch, oil, some vitamins and minerals, and thus accepted as a healthy foodstuff. This study was conducted to determine physical and chemical quality traits of many different oat landraces/cultivars. In this study, 251 local oat genotypes, collected from 10 provinces of Western and Middle Black Sea Regions of Turkey and four standard oat cultivars were grown over the experimental fields of the Agricultural Application and Research Center at Samsun Ondokuz Mayıs University for two years …

Fifty-three sugarcane accessions from Aklan, Iloilo, Cagayan, Nueva Vizcaya, Isabela, and Bohol were characterized using forty-two morphometric parameters and forty microsatellite markers. Twenty-six morphological characters using the Shannon-Weaver diversity index showed high variability (H’ = > 0.76) and were able to characterize the fifty-three sugarcane accessions. Cluster analysis of morphological traits based on sequential agglomerative hierarchical test and Euclidean distance revealed two groupings at 0.3 coefficient of dissimilarity. The clustering of some accessions was irrespective of their geographical origin indicating a high degree of phenotypic similarity in some accessions. Out of the forty microsatellite markers, twenty-five (63%) have a PIC value …

Poor grain filling is still a major problem in rice production. Recent attention in crop varietal improvement is focused on heritable delayed foliar senescence, enhanced root system, and fast-synchronous grain filling pattern. Nine genotypes were characterized for these three enhanced grain-filling traits to determine the role of these traits on grain yield. Based on heritable delayed foliar senescence, NSIC Rc436 and NSIC Rc512 were characterized as Type A, while PSB Rc18 and NSIC Rc514 as Type B. These genotypes had a significantly higher yield than IR64, owing to their high spikelets number. Data suggested a positive correlation between the delayed …
