In botany and horticulture, parthenocarpy is the natural or artificially induced production of fruit without fertilisation of ovules, which makes the fruit seedless. The phenomenon has been observed since ancient times [ 1 ] but was first scientifically described by German botanist Fritz Noll in 1902.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". [1]
Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles. The production of golden rice in 2000 marked a further improvement in the nutritional value of genetically modified food. [6] GM livestock have been developed, although, as of 2015, none were on the market. [7]
The banana plant is the largest herbaceous flowering plant. [2] All the above-ground parts of a banana plant grow from a structure called a corm. [3] Plants are normally tall and fairly sturdy with a treelike appearance, but what appears to be a trunk is actually a pseudostem composed of multiple leaf-stalks ().
Known as saging matsing and saging chonggo (both meaning 'monkey banana'), [17] saging na ligao ('wild banana'), and agutay in Filipino. Found in the Philippines. It is a significant maternal ancestor of many modern dessert bananas (AA and AAA groups). It is an attractive subspecies with blue-violet inflorescence and very pale green unripe fruits.
GM crops grown today, or under development, have been modified with various traits. These traits include improved shelf life , disease resistance , stress resistance, herbicide resistance , pest resistance , production of useful goods such as biofuel or drugs, and ability to absorb toxins and for use in bioremediation of pollution.
The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one. Genetically modified crops engineered to resist herbicides are now more available than conventionally bred resistant varieties; [ 20 ] in the USA 93% of soybeans and most of the GM maize grown is glyphosate tolerant ...
Gastric brooding frog: (2013) The gastric brooding frog, Rheobatrachus silus, thought to have been extinct since 1983 was cloned in Australia, although the embryos died after a few days. [76] Macaque monkey: (2017) First successful cloning of a primate species using nuclear transfer, with the birth of two live clones named Zhong Zhong and Hua ...
