Summary
Sugarcane genotype and soil type significantly influence beneficial bacteria (PGPB) recruitment and plant gene expression. This soil-genotype interaction reveals adaptive strategies for nutrient-poor conditions.
Area of Science:
- Plant Science
- Microbiology
- Genetics
Background:
- Soil properties critically influence sugarcane growth and its associated microbiome.
- The impact of soil type and sugarcane genotype on plant gene expression is not fully understood.
Purpose of the Study:
- To investigate the combined effects of soil type (clayey and sandy loam) and sugarcane genotype on microbiome composition and plant transcriptional profiles.
- To understand how soil and genotype interact to shape microbial recruitment and gene expression in sugarcane.
Main Methods:
- Analysis of bacterial communities from soil and sugarcane stalk tissues using 16S metataxonomic sequencing.
- Transcriptome analysis of sugarcane buds to assess gene expression patterns.
- Cultivation of sugarcane for 10 months under different soil and genotype conditions.
Main Results:
- Sugarcane genotypes exhibited distinct endophytic microbiota recruitment patterns dependent on soil type.
- In sandy loam, IACSP-5503 promoted diverse plant growth-promoting bacteria (PGPB) linked to nitrogen fixation and stress tolerance.
- In clayey soil, IACSP-6007 recruited PGPB associated with nutrient acquisition and defense, with both genotypes showing enhanced defense gene expression.
Conclusions:
- Sugarcane employs soil-dependent, genotype-specific microbial recruitment strategies, particularly the IACSP-5503 genotype in nutrient-poor conditions.
- Transcriptional plasticity in sugarcane is shaped by the interplay between soil properties and genetic makeup.
- Combined metataxonomic and transcriptome data provide insights into plant-microbe-soil interactions and adaptive responses.

02:27Background and Environment Affect Phenotype
8.0K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:57Adaptations that Reduce Water Loss
28.5K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

02:02Phloem and Sugar Transport
40.5K
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.

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

02:16Light Acquisition
9.8K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
