    Abstract Plant malectin/malectin-like receptor-like kinases (MRLKs) play crucial roles throughout the life course of plants. Here, we identified 23 SiMRLK genes from foxtail millet. All the SiMRLK genes were named according to the chromosomal distribution of the SiMRLKs in the foxtail millet genome and grouped into five subfamilies based on phylogenetic relationships and structural features. Synteny analysis indicated that gene duplication events may take part in the evolution of SiMRLK genes in foxtail millet. The expression profiles of 23 SiMRLK genes under abiotic stresses and hormonal applications were evaluated through qRT-PCR. The expression of SiMRLK1 , SiMRLK3 , SiMRLK7 and SiMRLK19 were significantly affected by drought, salt and cold stresses. Exogenous ABA, SA, GA and MeJA also obviously changed the transcription levels of SiMRLK1 , SiMRLK3 , SiMRLK7 and SiMRLK19 . These results signified that the transcriptional patterns of SiMRLKs showed diversity and complexity in response to abiotic stresses and hormonal applications in foxtail millet.

    Abstract Drought is a misfortune for crops. Wheat is a staple crop and its sustainability and adequate supply are vital to food security around the world. The development of drought-tolerant cultivars in wheat is a major challenge to breeders, therefore there is dire need of time to determine the genetic components of drought tolerance in wheat crop. To overcome intense drought stress, wheat plants undergo certain morphological and physiological changes and develop certain genetically adaptive mechanisms. Since wheat is an allotriploid with three sub-genomes, its adaptability molecular mechanisms to drought, particularly needs scientific attention. Here, we systematically and comprehensively reviewed the causes of wheat drought tolerance and the consequences for wheat physiology and genetics. The quantitative trait loci (QTL), which be function on the control of wheat drought tolerance, were comprehensively summarized by a meta-analysis and total 75 meta-QTLs (MQTLs) were identified. In addition, we summarized the genes tightly involved in wheat drought tolerance, and several important genes were selected to elucidate signaling networks related to the wheat drought tolerance. This review is integral to growing suitable strains in the worldwide arid regions to improve wheat yields under recent global climate change scenarios.

    Abstract Chitosan is a naturally occurring compound and is commercially produced from seafood shells. It has been utilized in the induction of the defense system in both pre and post-harvest fruits and vegetables against fungi, bacteria, viruses, and other abiotic stresses. In addition to that, chitosan effectively improves the physiological properties of plants and also enhances the shelf life of post-harvest produces. Moreover, chitosan treatment regulates several genes in plants, particularly the activation of plant defense signaling pathways. That includes the elicitation of phytoalexins and pathogenesis-related (PR) protein. Besides that, chitosan has been employed in soil as a plant nutrient and has shown great efficacy in combination with other industrial fertilizers without affecting the soil’s beneficial microbes. Furthermore, it is helpful in reducing the fertilizer losses due to its coating ability, which is important in keeping the environmental pollution under check. Based on exhibiting such excellent properties, there is a striking interest in using chitosan biopolymers in agriculture systems. Therefore, our current review has been centered upon the multiple roles of chitosan in horticultural crops that could be useful in future crop improvement programs.

    Abstract Although cytokinin response-regulators (RRs) are key components in cytokinin (CK) signal transduction pathway that modulate diverse developmental processes in plants, little is known about apple RR genes and their potential function in floral induction. In the present study, 34 putative RR genes were identified in apple and divided into three types: 19 A-type MdRRA, 11 B-type MdRRB, and 8 pseudo-response regulators (MdPRR). The expression pattern of all of the MdRRB genes, two MdRRA genes, and flowering-time genes were investigated in response to CK during floral induction in two different apple varieties. Results indicated that two MdRRA genes were immediately induced by the 6-BA treatment, while none of the MdRRB was. However the MdRRB genes were expressed at higher levels in 6-BA-treated buds and ‘Yanfu No. 6’ buds at most sampling time points. Moreover, the expression of MdSOC1a and MdSOC1b were also affected by the 6-BA treatment. Promoter regions of MdSOC1a and MdSOC1b were identified and analyzed; indicating that extended ARR1-binding sequences are located in the MdSOC1a and MdSOC1b. These results suggest that some B-type MdRR genes (MdRRB9 and MdRRB11; which were grouped into a cluster with ARR1) and flowering-time genes may be involved in the positive effect of CK on apple floral induction.

    Abstract Melatonin (N-acetyl-5-methoxytryptamine) is a nontoxic biological molecule produced in a pineal gland of animals and different tissues of plants. It is an important secondary messenger molecule, playing a vital role in coping with various abiotic and biotic stresses. Melatonin serves as an antioxidant in postharvest technology and enhances the postharvest life of fruits and vegetables. The application of exogenous melatonin alleviated reactive oxygen species and cell damage induced by abiotic and biotic stresses by means of repairing mitochondria. Additionally, the regulation of stress-specific genes and the activation of pathogenesis-related protein and antioxidant enzymes genes under biotic and abiotic stress makes it a more versatile molecule. Besides that, the crosstalk with other phytohormones makes inroads to utilize melatonin against non-testified stress conditions, such as viruses and nematodes. Furthermore, different strategies have been discussed to induce endogenous melatonin activity in order to sustain a plant system. Our review highlighted the diverse roles of melatonin in a plant system, which could be useful in enhancing the environmental friendly crop production and ensure food safety.

    Abstract BBX proteins play important roles in regulating plant growth and development including photomorphogenesis, photoperiodic regulation of flowering, and responses to biotic and abiotic stresses. At present, the genomes of seven Rosaceae fruit species have been fully sequenced. However, little is known about the BBX gene family and their evolutionary history in these Rosaceae species. Therefore, in this study total, 212 BBX genes were investigated from seven Rosaceae species (67 from Malus × domestica, 40 from Pyruscommunis, 22 from Rosa Chinesis, 20 from Prunuspersica, 21 from Fragariavesca, 22 from Prunusavium, and 20 from Rubusoccidentalis). The chemical properties, gene structures, and evolutionary relationships of the BBX genes were also studied. All the BBX genes were grouped into six subfamilies on the basis of their phylogenetic relationships and structural features. Analysis of gene structure, segmental and tandem duplication, gene phylogeny, and tissue-specific expression with the ArrayExpress database showed their diversification in function, quantity, and structure. The expression profiles of 19 MdBBX genes in different tissues were evaluated through qRT-PCR. These genes showed distinct transcription level among the tested tissues (bud, flower, fruit, stem, and leaf). Moreover, expression patterns of 19 MdBBX genes were examined during flowering induction time under flowering-related hormones and treatments (GA3, 6-BA, and sucrose). The expressions of the candidates BBX genes were affected and showed diverse expression profile. Furthermore, changes in response to these flowering-related hormones and treatment specifying their potential involvement in flowering induction. Based on these findings, BBX genes could be used as potential genetic markers for the growth and development of plants particularly in the area of functional analysis, and their involvement in flower induction in fruit plants.
