Summary: This study examined the frequency and patterns of allele-specific expression (ASE) in the highly polyploid sugarcane genome. The analysis revealed that most genes were expressed in proportion to the frequency of the allele in the genome, with a lower level of ASE reflecting the recent origin of polyploid hybrid sugarcane. ASE was found to be more common in defense-response genes and processes related to cell wall biosynthesis.

Summary: Through a meta-analysis of multiple studies, it was found that intercropping with legumes led to a decrease in sugarcane yield, with a high degree of variation. The study also revealed that higher annual temperatures and soil organic carbon reduced the competition of legumes on sugarcane yield, and late sowing and early destruction of legumes mitigated their negative impact. Furthermore, it was observed that the negative effect of legumes on sugarcane yield increased over years of intercropping. Further research is needed to better synchronize legume sowing and destruction dates in sugarcane agrosystems according to the climate and soil context, while balancing expected services and disservices.

Summary: The study optimized the identification of SNPs in sugarcane and recommended the use of long read size and paired-end reads, medium sequencing coverage, and Illumina NovaSeq6000 platform. Functional analysis showed that most of the SNPs landed within regulatory regions. The protocol demonstrated robustness in analyzing replicated genotypes.

Summary: The study evaluated the recent upgrade of APSIM-Sugar for the most cultivated Brazilian variety under water-limited conditions and projected the potential impacts of future climate changes on sugarcane crop performance. Results indicated that cane yields would decline in rainfed areas due to increased water stress and slightly decline in fully irrigated sites. The future projections showed variability between climate models, with large uncertainty towards the End-of-Century period.

Summary: This study aimed to assess the root colonization of sugarcane in intercropping systems with legumes or spontaneous weeds. The presence of legumes or weeds reduced the length of sugarcane fine roots, mainly in the topsoil, leading to a decrease in the soil volume colonized by sugarcane roots.

Summary: Large amounts of straw remained in the sugarcane fields after harvest. Indiscriminate straw removal or high amounts of straw on the field can negatively affect soil functions and crop yields. Leguminosae species grown during the sugarcane renewal period can potentially offset the negative implications of unsustainable straw management on soil and crop yield.

Summary: Ethanol derived from sugarcane has the potential to replace fossil fuel in Brazil, but it is important to balance greenhouse gas emissions. This study found that maintaining a certain amount of sugarcane straw in the field can reduce emissions and protect the soil while still using it for bioenergy production.

Summary: The study found no significant differences in crop and soil attributes under single and double row spacing configurations, but with the advancement in age of sugarcane crop, a potential superiority in performance of the double row spacing over single row spacing was observed. Adoption of the triple row spacing configuration caused negative effects on all crop and soil attributes.

Summary: This study evaluated cold tolerance in sugarcane progenies in Brazil by measuring physiological and biometric characteristics after frost events. Genetic variability for cold tolerance was detected within and between progenies, with the genotypic values highest in certain progenies such as RB996962 x RB016916.

Summary: RNA interference (RNAi) technology is a promising approach for pest control due to its high species selectivity. Recent advances in engineering plastid genome have shown that it is an effective way to protect plants from arthropod pests. This review discusses the progress, factors influencing efficacy, and strategies for improving efficiency of plastid-mediated RNAi (PM-RNAi) approach. The challenges and biosafety concerns of PM-RNAi technology for commercial production are also addressed.
