“…This is further supported by adoption of GM crops by 29 countries over 190 million ha with recent double digit growth in developing countries (ISAAA, 2019). It is estimated that 1.95 billion people have benefited from these technologies (Verma et al, 2022). Modern biotechnology provides options for diversification where a crop gene pool lacks needed diversity or is impossible to access (Van Etten et al, 2023).…”

Modern agriculture, especially monocultures, is increasingly blamed by proponents of agroecology for loss of biodiversity in agroecosystems through loss of natural vegetation and crop genetic diversity. However, loss of natural vegetation to agriculture has slowed in recent years, and the claim for 75% loss of crop genetic diversity due to the widespread use of improved crop varieties lacks evidence. The main objective of this perspective paper is to identify and analyze the kinds of diversity already developed by agricultural research in the context of their function, need and relevance to particular agroecological elements and principles related to biodiversity. The paper shows that biodiversity is already incorporated into agroecosystems in a multitude of ways such as improved crop varieties with functional traits; crop mixtures and dual-purpose crops in monocultures; inter-crops, strip crops or relay crops; cover crops; crop rotations; field margins; landscape diversification; crop-livestock systems; and agroforestry. Emphasis is also given to crop-associated biodiversity above ground and soil biodiversity. The paper highlights that more research is needed to (a) breed crops for multi-cropping systems; (b) improve understanding of how components of diversity interact within or across systems and scales; (c) understand the role of soil biodiversity in soil function; and (d) successfully use crop-associated biodiversity to manage pests and beneficial organisms. In the future, the promotion of agroecological principles should incorporate inputs from crop breeders, agronomists, ecologists and crop protectionists for the benefit of farmers, or such principles will remain aspirational.

“…Since the first commercialization of genetic modified (GM) tomato in 1996, the plantation area of GM plants is increasing dramatically. The GM plants have been cultivated more than 190 million hectares till 2021, benefiting 1.95 billion people in main GM plant production countries (United States, Brazil, Argentina, Canada, and India; Verma et al, 2021 ). The usage of GM crops has been proposed as the potential approach to solve the potential crisis of food shortage, climate change, sustainable development, and environment protection.…”

Evaluating the potential alteration of microbial communities is a vital step for biosafety of genetic modified plants. Recently, we have produced genetic modified Ma bamboo with increased cold and drought tolerance by anthocyanin accumulation. In this work, we aim to study the potential effects on microbial communities in rhizosphere soils during the cultivation of genetic modified bamboo. Rhizosphere and surrounding soil were collected at 3-month post-transplant. The amplicon (16S rDNA and ITS1) were sequenced for analysis of bacterial and fungal communities. Multiple software and database (Picrust2, FAPROTAX and FUNGulid) were applied to predict and compare the microbial functions involving basic metabolisms, nitrogen usage and presence of plant pathogens. There were no substantial change of the structure and abundance of rhizosphere soil microbial communities between genetic modified and wild type bamboo. For the surrounding soil, the bacterial biota α-diversity increased (chao1: 1,001 ± 80–1,276 ± 84, observed species: 787 ± 52–1,194 ± 137, PD whole tree: 75 ± 4–117 ± 18) and fungal biota α-diversity decreased (chao1: 187 ± 18–145 ± 10) in samples of genetic modified bamboo compared to those of wild type bamboo. The microbiota predicted functions did not change or had no negative alteration between genetic modified and wild type bamboo, in both rhizosphere and surrounding soils. As a conclusion, the growth of genetic modified bamboo had no substantial change on rhizosphere soil microbial communities, while minor alteration on bamboo surrounding soil microbial communities with no harmful effects. Moreover, the genetic modified bamboo had no negative effect on the predicted functions of microbiota in soil.
