The light-harvesting chlorophyll a/b-binding proteins of photosystem II family members are responsible for temperature sensitivity and leaf color phenotype in albino tea plant

•The 20 CsLHCB gene family members were comprehensively identified in the genomes of SCZ and LJ43.•The difference of amino acid of CsLHCB5 was a standard for identifying green and albino tea cultivars.•CsLHCB1.1, CsLHCB1.2, and CsLHCB2 may be the vital genes regulating the response to low-temperature stress.•CsLHCB2 protein served as an indicator of temperature sensitivity differences in albino tea cultivars.•The less accumulation of CsLHCB1 and CsLHCB5 proteins had a potential influence on albino leaves.
