Causes significant crop losses

Citrus production is declining worldwide due to several biotic and abiotic factors. The diseases caused by Phytophthora spp. present major economic risks since they are soil-borne and spread quickly if environmental conditions are favorable, or irrigation is poorly managed. Phytophthora species are present in all citrus-producing areas around the world causing significant losses in crop yield and affecting tree health.

Hypoxia induced by flooding causes significant losses to crop production almost every year. However, the molecular network of submergence signaling pathway is still poorly understood. According to previous studies, transgenic plants overexpressing the WRKY33 gene showed enhanced resistance to submergence stress.

Mediterranean cereal cyst nematode (CCN) Heterodera latipons is considered as one of the main CCN that causes significant economic losses in the production of intolerant cereal crops in Turkey. Accordingly, this study aimed at evaluating the effect of different storing temperatures and durations on the emergence of second-stage juveniles (J2s) of the nematode populations obtained from the eastern Mediterranean (Adana and Hatay) and south-eastern (Gaziantep and Kilis) regions of Turkey. The obtained results revealed a variation in the J2s hatching profiles of the regional nematode populations.

Cotton (Gossypium hirsutum) is considered a fairly salt tolerant crop however, salinity can still cause significant economic losses by affecting the yield and deteriorating the fiber quality. We studied a salt-tolerant upland cotton cultivar under temporal salt stress to unfold the salt tolerance molecular mechanisms.

Citrus is India's third-largest fruit crop, boosting production of 1.07 million hectares to 10.48 million tonnes (2013-14). Therefore, yields of 20-25 tonnes/ha have been recorded by some progressive growers, but average productivity is 9.78 tonnes/ha. In other countries where citrus is grown, these numbers are 40-50 tonnes, and the production life in orchards is much longer. High-strength cultivation with automatic fertilization has contributed significantly to the commercial citrus cultivation revolution in many countries.

Antitranspirants are the compounds or the substances applied to the leaves of the plants for the purpose of reducing water loss (transpiration) without causing a momentous change in the various important processes of the plant such as growth and photosynthesis. Antitranspirants are generally classified into four distinct categories viz., stomatal closing type, filmforming type, reflecting type and growth retardant.

Cowpea (Vigna unguiculata (L.)Walp.) is a poor men’s protein source. It is one of the most ancient human food sources and an important grain legume and hay crop in many tropical and subtropical regions. It is grown in Tamil Nadu and Andhra Pradesh widely as rainfed crop. Cowpea is affected by many diseases caused by viruses, bacteria and fungi. Among the fungal diseases, the charcoal rot caused by Macrophomina phaseolina (Tassi.) Goid causes significant loss in yield. M. phaseolinais a soil borne plant pathogen with a very wide host range.

Begomoviruses being the largest genera of Geminiviridae cause significant economical losses in a wide variety of crops in several tropical and subtropical regions of India and a major threats to food security. Begomoviruses are transmitted by the whitefly (Bemisia tabaci) in a circulative persistent manner. Begomoviruses as of their small genomes (ssDNA) and limited coding capacities, rely heavily on host machineries for infection. They interact with a wide range of plant proteins and process them to support viral DNA replication, gene expression, movement, and to neutralize host defenses.

Root parasitic weeds are a major constraint to crop production worldwide causing significant yearly losses in yield and economic value. These parasites cause their destruction by attaching to their hosts with a unique organ, the haustorium, that allows them to obtain the nutrients (sugars, amino acids, etc.) needed to complete their lifecycle.

Banana and plantains is the most important tropical fruit crop in the world, which serves as a major food and source of income in many countries. Bananas are severely infected by several pathogens one such Fusarium oxysoporum f. sp. Cubense which causes significant crop losses in the fields. In this study fusarium wilt screening was carried out on chemically induced mutants and molecular analysis was done to assess the acquired resistance to Fusarium oxysoporum f. sp. cubense.

Plants are constantly exposed to biotic stresses, which cause changes in plant metabolism including physiological damages, leading to crop productivity losses. This study was conducted to investigate bio-fertilizer applications (i.e., phosphorein, microbein, and combination of them at a ratio of 1:1 for seed before sowing) influences on two varieties (i.e., Giza 429 and Giza 40) of Vicia faba (L.) plant performances on borne diseasesinfected soil. Growth, yield and its quality, physio-biochemical attributes, nutrient contents and disease assessment were investigated.
