Mechanisms and Applications of Fungal Plant Growth Promotersfor Increased Crop Yields

Abstract

The soil fungus known as Trichoderma longibrachiatum may be found in almost every warm
environment. Wheat growth promotion and induction of plant resistance to parasitic nematodes have both
been attributed to the plant-growth boosting fungus Trichoderma longibrachiatum T6, however whether
or not T6 may also increase plant tolerance to salt stress is uncertain. Reduced agricultural output is a
global concern caused by soil salinity. It is uncertain, however, whether the plant-growth stimulating
fungus Trichoderma longibrachiatum T6 (T6) can improve plant tolerance to salt stress, despite evidence
that it stimulates wheat growth and induces resistance to parasitic nematodes.Wheat seedlings'
physiological, biochemical, and molecular responses to NaCl stress were studied, along with the impact
of the plant-growth-promoting fungus T6 on these responses.The nitrogen needs of legumes are mostly
satisfied by symbiotic nitrogen fixation, which also has some positive effects on subsequent crops in the
system by enriching the soil. The United Nations designated 2016 as the "International Year of pulses" to
draw attention to the crop's environmental benefits and boost its production. Extreme yield losses occur
regularly in grain legumes due to abiotic and biotic stressors. Despite widespread use of conventional and
molecular breeding techniques during the last five decades, global yields of legumes have remained
mostly unchanged. Use of biological solutions for crop production and protection is essential due to the
rising prices and bad effects of pesticides and fertilizers. One promising approach to creating
environmentally friendly, low-cost, and resource-conserving agricultural systems is to employ the plant
growth-promoting (PGP) fungus T6 to boost soil and plant health.
