Abstract
Plant pigments, particularly chlorophyll, are
crucial for photosynthesis and overall plant health, impacting not only the
plants themselves but also other organisms within the food chain. This study
investigates the effects of Groundnut Bud Necrosis Virus (GBNV) infection on
the chlorophyll content of cowpea leaves (Vigna unguiculata L. Walp).
Field samples of healthy and GBNV-infected cowpea leaves were collected from
the Jhunjhunu district of Rajasthan, India, and subjected to chlorophyll
pigment analysis. The results revealed a significant reduction in chlorophyll
a, chlorophyll b, and total chlorophyll in virus-infected leaves compared to
healthy ones. Specifically, chlorophyll a content decreased from 15.23±1.70
mg/g to 8.09±2.19 mg/g, chlorophyll b from 9.40±1.23 mg/g to 5.91±0.66 mg/g,
and total chlorophyll from 24.62±3.16 mg/g to 13.99±1.65 mg/g. The findings
align with previous studies on the chlorophyll-suppressing activities of plant
viruses, highlighting the profound and detrimental effects of GBNV on
photosynthetic efficiency and plant health.
