Abstract Recycling carbon dioxide (CO 2 ) into chemicals or fuels presents a promising avenue for mitigating carbon emissions and addressing the energy crisis. Plants serve as the ideal platform for the production of materials and chemicals, thanks to their innate capacity to directly use CO 2 in the synthesis of various organic compounds. While conventional methods for enhancing plant CO 2 fixation may reach their limits, novel technological solutions are imperative. Synthetic biology has illuminated the potential for biosynthesising multiple carbon sources through artificial CO 2 fixation pathways in vitro. Recent breakthroughs in photorespiratory bypasses and artificial carboxylation modules offer significant promise for engineering plants to improve carbon fixation, guiding the design and development of plants with more efficient CO 2 utilisation. In this context, we begin by summarising recent progress in designing or engineering in vitro CO 2 fixation pathways, as well as those solely established in microbes. Subsequently, we delineate strategies employed to enhance CO 2 fixation in plants. Finally, we explore potential methods for introducing artificial CO 2 fixation pathways into plants. These advancements are critical in advancing synthetic biology's efforts to tackle future challenges related to food and energy scarcity.
摘要:回收二氧化碳(CO 2)到化学品或燃料提出了一个有希望的途径,以减少碳排放和解决能源危机。植物是生产材料和化学品的理想平台,因为它们天生具有直接利用二氧化碳合成各种有机化合物的能力。虽然提高植物二氧化碳固定的传统方法可能达到极限,但新的技术解决方案势在必行。合成生物学已经阐明了通过体外人工co2固定途径生物合成多种碳源的潜力。最近在光呼吸旁路和人工羧化模块方面的突破为工程植物提供了改善碳固定的重大希望,指导了更有效利用二氧化碳的植物的设计和开发。在这种背景下,我们首先总结了最近在设计或工程的体外co2固定途径方面的进展,以及那些仅在微生物中建立的途径。随后,我们描述了增强植物对二氧化碳固定的策略。最后,我们探讨了将人工co2固定途径引入植物体内的潜在方法。这些进步对于推进合成生物学应对未来与粮食和能源短缺相关的挑战至关重要。

Abstract As the population expands livestock industry faces challenges including protein inadequacy and infectious diseases. Natural alternatives can help mitigate these issues, for example, by incorporating plant‐derived metabolites containing appropriate concentrations of natural antibiotics and health‐promoting agents into feed supplements. One promising source is cottonseed, a fat‐ and protein‐rich by‐product of cotton plant ( Gossypium spp.). During processing, gossypol, a natural substance with potential adverse effects when consumed long‐term, is often eliminated. However, gossypol has broad‐spectrum antiviral and antimicrobial properties, making it a potential solution to feed safety and animal health concerns. Here, we outline the challenges faced in animal husbandry and discuss how cottonseed may address diverse scenarios.
随着人口的增长,畜牧业面临着包括蛋白质不足和传染病在内的挑战。天然替代品可以帮助缓解这些问题,例如,将含有适当浓度的天然抗生素和健康促进剂的植物衍生代谢物加入饲料补充剂中。一个有希望的来源是棉籽,一种富含脂肪和蛋白质的棉花植物副产品(棉属植物)。棉酚是一种天然物质,长期食用会产生潜在的不良影响,在加工过程中,棉酚通常会被消除。然而,棉酚具有广谱抗病毒和抗菌特性,使其成为解决饲料安全和动物健康问题的潜在解决方案。在这里,我们概述了畜牧业面临的挑战,并讨论了棉籽如何解决各种情况。

The world is at a crossroad when it comes to agriculture. The global population is growing, and the demand for food is increasing, putting a strain on our agricultural resources and practices. To address this challenge, innovative, sustainable, and inclusive approaches to agriculture are urgently required. In this paper, we launched a call for Essential Questions for the Future of Agriculture and identified a priority list of 100 questions. We focus on 10 primary themes: transforming agri‐food systems, enhancing resilience of agriculture to climate change, mitigating climate change through agriculture, exploring resources and technologies for breeding, advancing cultivation methods, sustaining healthy agroecosystems, enabling smart and controlled‐environment agriculture for food security, promoting health and nutrition‐driven agriculture, exploring economic opportunities and addressing social challenges, and integrating one health and modern agriculture. We emphasise the critical importance of interdisciplinary and multidisciplinary research that integrates both basic and applied sciences and bridges the gaps among various stakeholders for achieving sustainable agriculture.

For millennia, agricultural science has been an integral part of humancivilization. From thefieldof “agriculture” to the practice of “cultivation”, these concepts have been fundamental in shaping human “culture”. As modern humans have existed for around 50,000 years, the total number of people who have ever lived on Earth is estimated to be over 108 billion. However, more than 99%of those people were born within the last 8000 years, following the first agricultural revolution. From “slash‐and‐burn” to “primitive agriculture”, the agricultural revolutions have been significant steps in raising humanity's capabilities. Today, agriculture stands as one of the most vital industries in the world, providing food, fibre, and energy to billions of people every day. However, the field also faces some of the more pressing challenges of our time, including climate change, chemical pollution, soil degradation, water scarcity, and biodiversity loss. Addressing these issues requires innovative, interdisciplinary, and sustainable approaches. This is why we are thrilled to introduce Modern Agriculture, a comprehensive, high‐quality journal that will serve as a leading platform for discussions, discoveries, and development in the field of agriculture. By prioritising cutting‐edge research and sustainable practices, the journal is poised to make significant impacts on the industry and beyond. It will bridge the gap between excellent scientific research on the bench and the pressing challenges facing the agriculture, bringing together scientists, engineers, farmers, entrepreneurs, policymakers, and the public society. Modern Agricultureaims toprovidea comprehensive perspective on innovative agriculture and its impact on society by publishing high‐quality articles related to various aspects of agricultural sciences, which can be outlined in three layers. First, the functions of agriculture in modern time, such as producing sufficient food and other products, promoting human health, and ensuring resource and environmental sustainability. Second, fulfiling these functions requires expertise from several disciplines, including green agriculture, smart agriculture, soil science, microbiology, pathology, chemistry, agroecology, economics, policies, social science, and veterinary science. Third, the journal's scope covers cutting‐edge sciences and technologies in each of the disciplines, such as agricultural biotechnology, engineering, crop design, breeding, informatics, and farming techniques. The journal's multidisciplinary and interdisciplinary approach aims to bridge the gap between different disciplines, facilitate collaboration and innovation, and promote the development of modern agriculture. In this very first issue, we are excited to present an article that lists “100EssentialQuestions for theFuture of Agriculture”. These questions were rigorously selected from over 400 submissions gathered from diverse communities around the world. Our objective was to explore t
几千年来,农业科学一直是人类文明不可分割的一部分。从“农业”领域到“耕作”实践,这些概念是塑造人类“文化”的根本。由于现代人类已经存在了大约5万年,因此地球上曾经生活过的总人数估计超过1080亿。然而,其中99%以上的人是在第一次农业革命之后的近8000年里出生的。从“刀耕火种”到“原始农业”,农业革命是提高人类能力的重要步骤。今天,农业是世界上最重要的产业之一,每天为数十亿人提供食物、纤维和能源。然而,该领域也面临着我们这个时代的一些更紧迫的挑战,包括气候变化、化学污染、土壤退化、水资源短缺和生物多样性丧失。解决这些问题需要创新、跨学科和可持续的方法。这就是为什么我们很高兴引进现代农业,这是一本全面的,高质量的期刊,将作为农业领域讨论,发现和发展的领先平台。通过优先考虑前沿研究和可持续实践,该杂志准备对行业内外产生重大影响。它将把科学家、工程师、农民、企业家、政策制定者和公共社会聚集在一起,弥合在板凳上的优秀科学研究与农业面临的紧迫挑战之间的差距。现代农业旨在通过发表与农业科学各个方面相关的高质量文章,提供有关创新农业及其对社会影响的全面视角,这些文章可以分为三个层次。第一,现代农业的功能,如生产足够的粮食和其他产品,促进人类健康,确保资源和环境的可持续性。其次,实现这些功能需要来自多个学科的专业知识,包括绿色农业、智慧农业、土壤科学、微生物学、病理学、化学、农业生态学、经济学、政策、社会科学和兽医学。第三,该期刊的范围涵盖了各个学科的前沿科学和技术,如农业生物技术、工程、作物设计、育种、信息学和农业技术。本刊采用多学科、跨学科的方式,旨在弥合不同学科之间的差距,促进合作与创新,促进现代农业的发展。在这第一期,我们很高兴地提出了一篇文章,列出了“农业未来的100个基本问题”。这些问题是从来自世界各地不同社区的400多份意见书中经过严格挑选出来的。我们的目标是探索农业面临的所有挑战,并优先考虑研究和解决问题的努力,促进社会经济发展和应用,以实现现代农业的关键功能。评选委员会选出的这些问题,不仅能启发和激励农业研究人员和实践者,还能为未来的农业创新提供蓝图。我们希望这篇文章能激发新的想法和合作,推动我们走向一个更高效、更健康、更可持续、更公平的农业未来。此外,我们还发表了一篇展望文章,讨论了减少呼吸二氧化碳以维持作物生产力和管理大气碳的可能性,一篇关于垂直农业最新突破的评论文章,以及几篇评论文章,以及其他涉及现代林业、智能育种、碳氮相互作用和现代农业中的硒等主题的文章。有多种文章类型供作者选择,包括报告新科学发现的原创研究文章,为农业研究或实践提供有用资源或工具的资源文章,概述或分析与农业相关的特定主题或领域的评论/观点,对先前发表的文章作出回应或评论的信函,发表作者对与农业有关的特定问题的意见或观点的评论,报道与农业有关的最新发展或新闻的新闻和观点,以及报道与农业创新有关的新专利的专利文章。更多的文章类型和解释可以在作者指南中找到。通过提供创新农业及其更广泛的社会影响的整体观点,现代农业将站在全球努力寻找解决当今世界面临的一些重大挑战的最前沿,例如

The interplay of carbon and nitrogen distribution: Prospects for improved crop yields 碳氮分布的相互作用:提高作物产量的前景
Pub Date : 2023-03-01 DOI: 10.1002/moda.7

Growth and productivity of plants primarily depend on the balanced distribution of carbon (C) and nitrogen (N) among different organs. Previous studies on crop improvement have focussed on the C or N assimilation and distribution. However, recent findings reveal that C and N form a complex integrated network and are often dependent on each other to affect crop productivity. The underlying physiological and molecular mechanisms involved in the coordinated distribution of C and N among different plant organs are yet to be fully uncovered. Crucial roles in regulating C and N balance are played by transporters that mediate their movement across different organs. In Cotton, which has an indeterminate growth pattern, source–sink assimilate distribution could be a major bottleneck impeding fibre productivity. This review summarises our current understanding of C and N transport mechanisms, explores and compares different physiological and molecular approaches involved in the C–N distribution cascade, including cotton and other plant species. A comprehensive understanding of these integrated regulatory mechanisms is crucial for improving crop yields and fibre productivity.
植物的生长和生产力主要取决于碳(C)和氮(N)在不同器官中的平衡分布。以往对作物改良的研究主要集中在碳氮的同化和分配上。然而,最近的研究结果表明,碳和氮形成了一个复杂的综合网络,并且经常相互依赖来影响作物生产力。C和N在植物不同器官间协调分布的生理和分子机制尚未完全揭示。转运蛋白在调节碳氮平衡中起着至关重要的作用,转运蛋白介导它们在不同器官之间的运动。在生长模式不确定的棉花中,源库同化物的分布可能是阻碍纤维生产力的主要瓶颈。本文综述了目前对碳氮转运机制的认识,探讨并比较了包括棉花和其他植物在内的碳氮转运级联的不同生理和分子途径。全面了解这些综合调控机制对于提高作物产量和纤维生产力至关重要。

Forest is the most important terrestrial component of the Earth's biosphere, containing nearly 80% of terrestrial biodiversity. However, climate change and population growth are exacerbating deforestation and forest degradation. Reforestation efforts aim to restore ecosystems, but the effectiveness of traditional tree plantations in repairing the ecological function of native forests is controversial. The ideal scenario for forestry in the future is to meet the growing demand for forest products while keeping forest sustainable development. One possible way forward is to greatly improve the productivity and adaptability of forests through molecular breeding to use fewer Short Rotation Intensive Culture (SRIC) plantations to produce sufficient forest products. In the last 2 decades, advances in biotechnologies such as high‐throughput sequencing and genome editing are transforming tree breeding and forestry. Here, we propose possible future directions for modern forestry, including molecular design tree breeding, agroforestry and mixed farming, sustainable and biosphere friendly forestry.
森林是地球生物圈最重要的陆地组成部分,包含近80%的陆地生物多样性。然而,气候变化和人口增长正在加剧森林砍伐和森林退化。重新造林的目的是恢复生态系统,但传统人工林在修复原生森林生态功能方面的有效性存在争议。未来林业的理想情景是在满足日益增长的林产品需求的同时保持森林的可持续发展。一种可能的方法是通过分子育种大幅度提高森林的生产力和适应性,减少使用短轮作集约栽培(SRIC)人工林来生产足够的林产品。在过去的20年里,高通量测序和基因组编辑等生物技术的进步正在改变树木育种和林业。在此,我们提出了现代林业未来可能的发展方向,包括分子设计树木育种、农林业和混合农业、可持续和生物圈友好型林业。

However, climate change and population growth are exacerbating deforestation and forest degradation. Reforestation efforts aim to restore ecosystems, but the effectiveness of traditional tree plantations in repairing the ecological function of native forests is controversial. The ideal scenario for forestry in the future is to meet the growing demand for forest products while keeping forest sustainable development. One possible way forward is to greatly improve the productivity and adaptability of forests through molecular breeding to use fewer Short Rotation Intensive Culture (SRIC) plantations to produce sufficient forest products.
