Summary
High-yield sugarcane genotypes exhibit superior metabolic balance, efficiently utilizing nutrients and maintaining antioxidant capacity. This balance promotes growth without activating costly defense systems, leading to increased sugarcane yield and sucrose accumulation.
Area of Science:
- Agricultural Science
- Plant Biochemistry
- Genetics
Background:
- Sugarcane yield and sucrose content vary significantly among genotypes.
- Biochemical traits influencing this variation are not well understood.
Purpose of the Study:
- To investigate the association between ionomic, hormonal, flavonoid, and photosynthetic pigment profiles and sugarcane yield.
- To identify biochemical markers for high-yielding sugarcane cultivars.
Main Methods:
- Profiling of six contrasting sugarcane cultivars for ionomic, hormonal, flavonoid, and pigment composition.
- Multivariate and canonical correlation analyses to link biochemical traits with yield and morphological data.
Main Results:
- High-yield cultivars (ZZ14, GL1215) showed enrichment in potassium, magnesium, and calcium, and lower levels of growth hormones.
- Genotypes with high hormone levels (LT1790) exhibited suboptimal yield due to trade-offs with defense systems.
- Nutrient balance and metabolite profiles strongly correlated with plant height, stem diameter, and sugar concentration.
Conclusions:
- High-yield sugarcane genotypes achieve superior metabolic balance through efficient nutrient uptake and antioxidant capacity.
- Favorable hormone profiles promote growth without excessive defense activation, crucial for maximizing yield and sucrose accumulation.

01:56Plant Hormones
27.2K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

01:58Fruit Development, Structure, and Function
24.9K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

02:02Phloem and Sugar Transport
39.7K
Like many living organisms, plants have tissues that specialize in specific plant functions. For example, shoots are well adapted to rapid growth, while roots are structured to acquire resources efficiently. However, sugar production is primarily restricted to the photosynthetic cells that reside in the leaves of angiosperm plants. Sugar and other resources are transported from photosynthetic tissues to other specialized tissues by a process called translocation.

02:04Regulation of Transpiration by Stomata
30.9K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

01:02Glucose Homeostasis: Regulation of Blood Glucose
3.8K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
