“…Some of the tree species used can be easily characterized as ''wonder-trees'' by their multiple environmental role and products. For example, Moringa oleifera (Lam) (Boumenjel et al 2021) represents a promising choice in arid zones where water is a limiting growth factor. Based on the results from greenhouse and field research conducted in Tunisia, it appears that Moringa oleifera can withstand severe water stress while maintaining sufficient root and foliar growth, rending this species a valuable candidate to rehabilitate and enhance soil quality in arid zones.…”

Agroforestry is a traditional land use system that may contribute to the solution of environmental problems in agriculture. Agroforestry is the practice of deliberately integrating woody vegetation (trees or shrubs) with crops and/or animal systems to benefit from the resulting ecological and economic interactions. Recent research indicates that a wider adoption of agroforestry principles and practices is a key means by which the global agri-food sector might achieve more sustainable methods of food and fiber production by producing both economic benefits for farmers and environmental benefits for society. Agroforestry provides numerous provisioning, regulating, cultural and supporting ecosystem services and environmental benefits while promoting eco-intensification based on a more efficient use of the resources. Nevertheless, there is only little published recent information on the contribution of agroforestry to the environment in general and on climate change, carbon sequestration and forest fires in particular. In this special issue a number of articles are included that provide a kaleidoscope of the environmental benefits that agroforestry provides to the environment.

“…Worldwide demands for food entail the cultivation of drought stress-resistant, medicinally, and nutritionally important plants such as M. oleifera [ 17 ]. M. oleifera grown under water stress of −1.5 MPa triggered by polyethylene glycol (PEG-6000) showed a positive stress resistance response but the overall growth and development were compromised compared to control [ 18 ]. Keeping in view the importance of M. oleifera as a global miracle tree, the current study was rationalized to enhance the drought stress resistance of M. oleifera with better growth performance.…”

Endophytic Fungal Consortia Enhance Basal Drought-Tolerance in Moringa oleifera by Upregulating the Antioxidant Enzyme (APX) through Heat Shock Factors

Global climate change has imposed harsh environmental conditions such as drought. Naturally, the most compatible fungal consortia operate synergistically to enhance plant growth and ecophysiological responses against abiotic strains. Yet, little is known about the interactions between phytohormone-producing endophytic fungal symbionts and plant growth under drought stress. The existing research was rationalized to recognize the role of newly isolated drought-resistant, antioxidant-rich endophytic fungal consortia hosting a xerophytic plant, Carthamus oxycantha L., inoculated to Moringa oleifera L. grown under drought stress of 8% PEG (polyethylene glycol-8000). Under drought stress, the combined inoculation of endophytic strain Microdochium majus (WA), Meyerozyma guilliermondi (TG), and Aspergillus aculeatus (TL3) exhibited a significant improvement in growth attributes such as shoot fresh weight (1.71-fold), shoot length (0.86-fold), root length (0.65-fold), dry weight (2.18-fold), total chlorophyll (0.46-fold), and carotenoids (0.87-fold) in comparison to control (8% PEG). Primary and secondary metabolites were also increased in M. oleifera inoculated with endophytic consortia, under drought stress, such as proteins (1.3-fold), sugars (0.58-fold), lipids (0.41-fold), phenols (0.36-fold), flavonoids (0.52-fold), proline (0.6-fold), indole acetic acid (IAA) (4.5-fold), gibberellic acid (GA) (0.7-fold), salicylic acid (SA) (0.8-fold), ascorbic acid (ASA) (1.85-fold), while abscisic acid (ABA) level was decreased (−0.61-fold) in comparison to the control (8% PEG). Under drought stress, combined inoculation (WA, TG, TL3) also promoted the antioxidant activities of enzymes such as ascorbate peroxidase (APX) (3.5-fold), catalase (CAT) activity (1.7-fold), and increased the total antioxidant capacity (TAC) (0.78-fold) with reduced reactive oxygen species (ROS) such as H2O2 production (-0.4-fold), compared to control (8% PEG), and stomatal aperture was larger (3.5-fold) with a lesser decrease (-0.02-fold) in water potential. Moreover, combined inoculation (WA, TG, TL3) up regulated the expression of MolHSF3, MolHSF19, and MolAPX genes in M. oleifera under drought stress, compared to the control (8% PEG), is suggestive of an important regulatory role for drought stress tolerance governed by fungal endophytes. The current research supports the exploitation of the compatible endophytic fungi for establishing the tripartite mutualistic symbiosis in M. oleifera to alleviate the adverse effects of drought stress through strong antioxidant activities.

“…The species tolerates harsh environmental and climatic conditions and does not rely on moisture from immediate rainfall as it stores water within the roots and other succulent tissues for utilization during periods of water scarcity [5]. M. oleifera is a promising species in agroforestry systems [6].…”

There is increasing narrowing of the genetic base of exotic species introduced in many parts of the world. This is causing a restricted genetic diversity and consequential loss of biotic and abiotic tolerance of these species. Hence, there is need to establish the genetic stability of such species for future genetic broadening. One such plant is Moringa oleifera Lam. which belongs to the family moringaceae; a monogeneric family of shrubs and trees consisting of 13 species and is native to India. M. oleifera is the most economically useful species in the genus and is widely cultivated and naturalized in tropical and subtropical areas and in over 60 countries worldwide. In Kenya, M. oleifera is widely cultivated in coast and some parts of Eastern Kenya. A provenance trial was set up at South Eastern Kenya University (SEKU), located at Kwa Vonza location, lower Yatta Sub-County, Kitui County. The aim of the provenance trial was i) to determine whether the collected Moringa exhibited different growth and fruiting habits and ii) if so, select the best performing provenances for large-scale propagation of the species in Kenya. The trial involved fifteen provenances selected from a wide geographical region in Eastern and Coastal regions of Kenya. Each provenance consisted of 200 seedlings at a spacing of 2m by 2m and was replicated three times. The experiment was laid in a randomized complete block design (RCBD). Growth data (diameter and height), fruiting and fruit maturation were measured for a period of 12 months. Monthly growth data were used to generate horizontal and vertical growth curves. Duncan Multiple Range Test (DMRT) and test of homogeneity of variances were used to detect existence of statistically significant differences in the fifteen provenances. The results indicated statistically significant differences (p<0.05) between the provenances with the Mwakiki provenance being the most significantly different and the Mackinnon one being the least. Intra-seasonal fruiting and fruit maturation peaked in the months of November and December. Pearson and Spearman correlation analysis showed very strong positive correlations between growth and yield traits. The results also showed that the Mwakiki provenance had a stable performance in the three traits studied and is recommended for adoption especially where fruit production is the preferred end product. Molecular analysis of all the species should also be done to determine the genetic base status and correlate them with this phenotypic analysis.
