Dolores A. Ramirez (born September 20,1931) is a Filipino geneticist. She specializes in plant breeding and plant cytogenetics. She was named a National Scientist of the Philippines in 1998.
Dolores A. Ramirez was born on September 20,1931,in Calamba,Laguna to Leonor Altoveros and Augusto U. Ramirez. She was the oldest of eight children and her father died when she was young. She graduated from Laguna Institute in 1952 with a First Honorable Mention award. [1]
She attended the University of the Philippines Los Baños,earning a bachelor of science in agriculture,magna cum laude,in 1956. Her thesis,under Dioscoro L. Umali,concerned the nature of lodging in rice. She received a Rockefeller Foundation scholarship and attended the University of Minnesota in the United States. She studied under cytogeneticist Charles Burnham and earned her MSc in cytogenetics in 1958. She continued on to Purdue University,studying under geneticist Mark L. Tomes. She received her PhD in biochemical genetics in 1963,minoring in plant pathology and plant physiology. [1]
After Ramirez completed her PhD,she returned to the University of the Philippines where she conducted research into the breeding and cytogenetics of plants. [2] She was hired by the College of Agriculture of the University of the Philippines Los Baños as an assistant professor in 1964. She attained the position of associate professor in 1969 and full professor in 1974. She was named a full University Professor in 1995. [1]
Much of Ramirez's research has been into plants important to agriculture in the Philippines. She researched the genetic basis of chemical resistance factors of Cercospora ,which causes the formation of leaf spots in mung beans. She also studied the cytogenetics of hybrids of rice,tracing the cause of sterility from crosses with wild strains. Her plant research led to improved varieties of fruit,sugarcane,rice,coconut,and ornamentals. She conducted research with Evelyn Mae Tecson-Mendoza on how macapuno coconut genes that characterize endosperm cell walls are affected by high galactomannan metabolism. [1]
Ramirez served as an associate editor of the Philippine Journal of Crop Science and the Philippine Phytopathological Journal. She was the editor-in-chief of The Philippine Agriculturist for 10 years. She served on the Board of Trustees of the International Maize and Wheat Improvement Center [1] and held the Professorial Chair for Genetics of the Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA) from 1974 to 1976. [3]
In August 2023,she was featured on the cover of Vogue Philippines. [4]
The coconut tree is a member of the palm tree family (Arecaceae) and the only living species of the genus Cocos. The term "coconut" can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a nut. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics.
Barbara McClintock was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock received her PhD in botany from Cornell University in 1927. There she started her career as the leader of the development of maize cytogenetics, the focus of her research for the rest of her life. From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis—a mechanism by which chromosomes exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of genetic information. She was recognized as among the best in the field, awarded prestigious fellowships, and elected a member of the National Academy of Sciences in 1944.
Golden rice is a variety of rice produced through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice. It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A. Genetically modified golden rice can produce up to 23 times as much beta-carotene as the original golden rice.
The University of the Philippines Los Baños, also referred to as UP Los Baños or colloquially as Elbi, is a public research university primarily located in the towns of Los Baños and Bay in the province of Laguna, some 65 kilometers southeast of Manila. It traces its roots to the UP College of Agriculture (UPCA), which was founded in 1909 by the American colonial government to promote agricultural education and research in the Philippines. American botanist Edwin Copeland served as its first dean. UPLB was formally established in 1972 following the union of UPCA with four other Los Baños and Diliman-based University of the Philippines (UP) units.
Mankombu Sambasivan Swaminathan was an Indian agronomist, agricultural scientist, geneticist, administrator and humanitarian. Swaminathan was a global leader of the green revolution. He has been called the main architect of the green revolution in India for his leadership and role in introducing and further developing high-yielding varieties of wheat and rice.
Gnetum gnemon is a gymnosperm species of Gnetum, its native area spans from Mizoram and Assam in India down south through Malay Peninsula, Malay Archipelago and the Philippines in southeast Asia to the western Pacific islands. Common names include gnetum, joint fir, two leaf, melinjo/belinjo (Indonesian), bago (Filipino), and tulip.
Chlorogenic acid (CGA) is the ester of caffeic acid and (−)-quinic acid, functioning as an intermediate in lignin biosynthesis. The term chlorogenic acids refers to a related polyphenol family of esters, including hydroxycinnamic acids with quinic acid.
Centella asiatica, commonly known as Indian pennywort, Asiatic pennywort, spadeleaf, coinwort or gotu kola, is a herbaceous, perennial plant in the flowering plant family Apiaceae. It is native to tropical regions of Africa, Asia, Australia, and islands in the western Pacific Ocean. It is consumed as a culinary vegetable and is used in traditional medicine.
Petiveria is a genus of flowering plants in the pigeonberry family, Petiveriaceae. The sole species it contains, Petiveria alliacea, is native to Florida and the lower Rio Grande Valley of Texas in the United States, Mexico, Central America, the Caribbean, and tropical South America. Introduced populations occur in Benin and Nigeria. It is a deeply rooted herbaceous perennial shrub growing up to 1 m (3.3 ft) in height and has small greenish piccate flowers. The roots and leaves have a strong acrid, garlic-like odor which taints the milk and meat of animals that graze on it.
Science and technology in the Philippines describes scientific and technological progress made by the Philippines and analyses related policy issues. The main agency responsible for managing science and technology (S&T) is the Department of Science and Technology (DOST). There are also sectoral councils for Forestry, Agriculture and Aquaculture, the Metal Industry, Nuclear Research, Food and Nutrition, Health, Meteorology, Volcanology and Seismology.
Agriculture in the Philippines is a major sector of the economy, ranking third among the sectors in 2022 behind only Services and Industry. Its outputs include staples like rice and corn, but also export crops such as coffee, cavendish banana, pineapple and pineapple products, coconut, sugar, and mango. The sector continues to face challenges, however, due to the pressures of a growing population. As of 2022, the sector employs 24% of the Filipino workforce and it accounted for 8.9% of the total GDP.
Grona triflora, known as creeping tick trefoil or three-flower beggarweed, is a plant in the family Fabaceae. It is native to tropical regions around the globe and introduced to subtropical regions including the southern United States.
