    Javed Rashid1,2, Imran Khan1, Irshad Ahmed Abbasi3, Muhammad Rizwan Saeed4, Mubbashar Saddique5,*, Mohamed Abbas6,7

    CMC-Computers, Materials & Continua, Vol.76, No.3, pp. 3897-3920, 2023, DOI:10.32604/cmc.2023.040356

    Abstract Many plant species have a startling degree of morphological similarity, making it difficult to split and categorize them reliably. Unknown plant species can be challenging to classify and segment using deep learning. While using deep learning architectures has helped improve classification accuracy, the resulting models often need to be more flexible and require a large dataset to train. For the sake of taxonomy, this research proposes a hybrid method for categorizing guava, potato, and java plum leaves. Two new approaches are used to form the hybrid model suggested here. The guava, potato, and java plum plant species have been successfully… More >

    Biological Analysis and Response to Low Phosphate Stress of Phosphate Transporter Family 1 (PHT1)) Genes in Solanum tuberosum L.

    Yangyang Du1, Yuanyuan Bao2, Lu Zheng1, Qinglong Tian1, Xinyong Zhang1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2325-2348, 2023, DOI:10.32604/phyton.2023.027642

    Abstract Inorganic phosphate (Pi) is one of the main nutrients necessary for plant growth. Phosphate transporters mediate the acquisition, transport and recycling of phosphate, which is essential for plant growth and development. Although PHT1 has been reported in many plants at home and abroad, it is rarely studied in potato. Therefore, it is of great significance to study the PHT1 family members in order to understand the molecular response mechanism of potato in low phosphate state. In this study, a total of 6 potato PHT1 genes were identified and isolated. It was found that after the expression of different members of… More >

    In silico Prediction and Analysis of Potential Off-Targets and Off-Target Mutation Detection in StERF3-Gene Edited Potato Plants

    Hafiza Arooj Razzaq1, Siddra Ijaz1,*, Imran Ul Haq2, Faisal Saeed Awan1

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2451-2460, 2023, DOI:10.32604/phyton.2023.030501

    Abstract The imperative aspect of the CRISPR/Cas9 system is a short stretch of 20 nucleotides of gRNA that control the overall specificity. Due to the small size, the chance of its multiple occurrences in the genome increases; however, a few mismatches are tolerated by the Cas9 endonuclease activity. An accurate and careful in silico-based off-target prediction while target selection is preferred to address the issue. These predictions are based on a comprehensive set of selectable parameters. Therefore, we investigated the possible off-target prediction and their screening in StERF3 gene-edited potato plants while developing StERF3-loss-of-function mutants using CRISPR/Cas9 approach. The 201 off-targets… More >
