“…There are also differences in disease and nematode resistance among the various MGs depending on the major biotic factors limiting yield in the intended growing regions (Hartman et al, 2005;Vuong et al, 2013). For instance, a study of 128 soybean plant introductions, including three MGs observed a difference in the amount of seed infected by Cercospora kikuchii (T. Matsumoto & Tomoy.)…”

Growers across theU.S. Southeast use a diversity of soybean [Glycine max (L.)Merr.] planting dates, maturity groups, and seeding rates for soybean production depending on their rotational complexity. Studies were conducted across seven North Carolina environments in 2019 and 2020 to determine the effect of planting date (mid-March through mid-July), maturity group (MG 2-8), and seeding rate (185,434 seeds ha -1 ) on soybean emergence, stand, and yield. Across environments, soybean typically emerged more quickly with later planting dates; however, there were location-specific variations in soybean emergence due to weather conditions around the time of planting. The longest and shortest emergence periods were 26 d for soybean planted in mid-March and 4 d for soybean planted in June and July, respectively. In the higher yielding environments, yield was maximized with MG 3-4 cultivars planted at early April planting dates and yield declined as planting was delayed. In the low yield environments, yield was maximized with late April to mid-May planting dates, typically with MG 5-7 cultivars. There was a penalty in both yield environments to planting past mid-May and in the low yield environments for planting before mid-April. Across environments, yields tended to be more similar among cultivars higher than MG 3 at planting dates in June and July. The effect of seeding rate on soybean yield was variable across planting dates, maturity groups, and yield environments. Future research is needed in North Carolina to validate the planting date and maturity group interactions on yield observed in this experiment to capture more variation in weather conditions.

“…are not only a major pest on soybean, but also attack hundreds of other important crops, placing them amongst the most common and damaging crop pests world‐wide (Mitkowski and Abawi, ). Although sources of resistance to cyst nematodes and RKNs have been identified in soybean, they are unlinked, and elite cultivars with resistance to both nematodes are currently lacking (Vuong et al ., ). Thus, in soybean production areas in which cyst nematodes and RKNs coexist, these pests pose a particular challenge for growers because they are typically managed with different cultivars as well as different rotation strategies.…”

Plant elicitor peptides (Peps) are widely distributed among angiosperms, and have been shown to amplify immune responses in multiple plant families. Here, we characterize three Peps from soybean (Glycine max) and describe their effects on plant defences against two damaging agricultural pests, the root-knot nematode (Meloidogyne incognita) and the soybean cyst nematode (Heterodera glycines). Seed treatments with exogenous GmPep1, GmPep2 or GmPep3 significantly reduced the reproduction of both nematodes. Pep treatment also protected plants from the inhibitory effects of root-knot nematodes on above-ground growth, and up-regulated basal expression levels of nematode-responsive defence genes. GmPep1 induced the expression of its propeptide precursor (GmPROPEP1), a nucleotide-binding site leucine-rich repeat protein (NBS-LRR), a pectin methylesterase inhibitor (PMEI), Respiratory Burst Oxidase Protein D (RBOHD) and the accumulation of reactive oxygen species (ROS) in leaves. In addition, GmPep2 and GmPep3 seed treatments up-regulated RBOHD expression and ROS accumulation in roots and leaves. These results suggest that GmPeps activate plant defences through systemic transcriptional reprogramming and ROS signalling, and that Pep seed treatments represent a potential strategy for nematode management.

“…The current best management strategy to control SCN infection in soybean fields is the use of nematode‐resistant cultivars coupled with effective cultural practices. However, the frequent use of the same resistant germplasm has provoked the ability of SCN to adapt to these strategies and readily overcome resistance (Vuong et al, 2013).…”

Protein kinases phosphorylate proteins for functional changes and are involved in nearly all cellular processes, thereby regulating almost all aspects of plant growth and development, and responses to biotic and abiotic stresses. We generated two independent co‐expression networks of soybean genes using control and stress response gene expression data and identified 392 differentially highly interconnected kinase hub genes among the two networks. Of these 392 kinases, 90 genes were identified as “syncytium highly connected hubs”, potentially essential for activating kinase signalling pathways in the nematode feeding site. Overexpression of wild‐type coding sequences of five syncytium highly connected kinase hub genes using transgenic soybean hairy roots enhanced plant susceptibility to soybean cyst nematode (SCN; Heterodera glycines) Hg Type 0 (race 3). In contrast, overexpression of kinase‐dead variants of these five syncytium kinase hub genes significantly enhanced soybean resistance to SCN. Additionally, three of the five tested kinase hub genes enhanced soybean resistance to SCN Hg Type 1.2.5.7 (race 2), highlighting the potential of the kinase‐dead approach to generate effective and durable resistance against a wide range of SCN Hg types. Subcellular localization analysis revealed that kinase‐dead mutations do not alter protein cellular localization, confirming the structure–function of the kinase‐inactive variants in producing loss‐of‐function phenotypes causing significant decrease in nematode susceptibility. Because many protein kinases are highly conserved and are involved in plant responses to various biotic and abiotic stresses, our approach of identifying kinase hub genes and their inactivation using kinase‐dead mutation could be translated for biotic and abiotic stress tolerance.
