The objective of this study was to estimate CO2-eq emissions from milk production and evaluate the potential of integrated livestock-forest system to mitigate emissions via Carbon stocked in soil and eucalyptus trees in Santa Barbara Farm located in the State of Goiás, Central West region of Brazil, within the savanna biome (Cerrado). Tropical soils in the Cerrado are one of the most ancient in the world and therefore long-date weathered. In 2016, integrated livestock-forest system (ILF) was implemented in a pasture on a Geric Xanthic Ferralsol (Dystric Humic). Soil organic C (Corg) stocks in the Ferralsol were around 6 to 7 Mg ha-1 within 0.0-0.3 m layer. In the 4-year old ILF system, there were an extra 0.441 Mg ha-1 Corg stock related to same soil under continuous pasture within 0.0-1.0 m layer. The estimated total emission due to dairy production per year at farm level was around 520 Mg CO2-eq or 142 Mg of C emitted to atmosphere. Most of emissions were related to animal feeding (58%). Considering total Corg stocks in 1-m depth of soil and 2-years old eucalyptus trees in the ILF system, yet the C balance was positive, indicating emission of 102.93 Mg of C to the atmosphere due to the present dairy production system conducted at Santa Barbara farm. At 4 years after implementation, the ILF system was a sink of 38.94 Mg of C from atmosphere, offsetting around 28% of total emissions, a significant number once the farmer intends to keep and increment the ILF area in order to sustain milk production levels due to thermal comfort delivered to the cows by trees.

Nematodes of the genus Meloidogyne pose a challenge to worldwide agricultural production, especially to economically relevant crops, such as cotton and soybean. They induce feeding sites on plant roots, leading to reduced crop yields due to impaired water and nutrient absorption. Current control methods are insufficient for this phytopathogen management. Chemical nematicides are highly toxic, crop rotation is inefficient for population elimination, and commercially resistant or tolerant cultivars are scarce. Thus, the development of less susceptible biotechnological cultivars for efficient nematode management is required. The GmGlb1-1 gene of Glycine max encodes a protein related to nitric oxide metabolism that accumulates in roots during nematode parasitism. Studies have shown that overexpression of GmGlb1-1 enhances plant resilience to oxidative stress and improves cellular homeostasis. In addition, the GmEXPA1 gene encodes an enzyme involved in cell wall lignification processes and, when overexpressed, promotes adaptability to adverse conditions. Independent overexpression of both genes has been associated with reduced susceptibility of Arabidopsis thaliana and Nicotiana tabacum to M. incognita. However, the combined effect of such genes in increasing plant resistance to nematodes has not yet been investigated. Here, we proposed to overexpress the GmGlb1-1 and GmEXPA1 genes in cotton to confer reduced susceptibility to M. incognita. Eight independent transgenic events were generated with a 1% transformation efficiency. Characterization of transgenic plants was performed by PCR and enzyme-linked immunosorbent assays. Five independent transformation events with high transgenic protein accumulation were selected for generation advancement. Progenies of T2 generation were inoculated with 2000 ppJ2 juveniles of M. incognita at 15 days after seed germination in an assay performed in greenhouse with 20 replicates of each event. After 90 days, the roots were evaluated for the incidence of galls using a qualitative rating scale. Two transgenic events stood out by having superior scores, indicating a reduction in the number of galls. Additional analyses are in progress to determine quantitative effects of the parasitism in transgenic plants. Biotechnology approaches offer great potential for application in commercial crop cultivars aiming to reduce plant susceptibility to root-knot nematodes and develop sustainable agriculture with less dependence on pesticides.
