Eight genes were targeted by at least two miRNAs; for example, MYB33 and MYB81 were targeted by miR159 and miR319, and SPL2 and SPL13b were targeted by miR156 and miR535.

Many of these targets encode transcription factors; for example, they include the SPL (target of miR156 and miR535), MYB (miR159, miR319 and new-18), HAM3 (miR171), NAC (miR164), ARF (miR160, miR167 and miR169), TCP (miR319), GRF (miR396 and miR477) and SIGMA (new-11) genes.

Several miRNAs are involved in starch accumulation in rice [6], and five of them (miR159, miR160, miR164, miR167 and miR319) also had the same targets in cassava.

It was inferred that miR159 could directly or indirectly affect starch biosynthesis in cassava.

Both miR159 and miR319 shared sequence identity at 20 of 22 nucleotides, and the expression level of miR159 was far greater than that of miR319 in two cultivars and the wild progenitor.

A previous study reported that miR159 regulated MYB mRNAs, and miR319 predominantly acted on TCP mRNAs in Arabidopsis [27].

Therefore, similar to the case in Arabidopsis, MYB transcription factors were mainly regulated by miR159 in cassava.

In vitro binding assays [77] revealed the ability of AC4 of ACMV to bind single stranded forms of miR159 and presumably inactivate the mature miRNAs, thus blocking the normal miRNA -mediated regulation of target mRNAs and thus resulting in developmental disturbances.

Interestingly, in this study the miR156, miR159, miR160, miR164, miR169, miR170, miR171, miR395 and miR395 were predicted and their expression was detected, which also were found in Jatropha, cassava, Ricinus communis and Hevea brasiliensis in response to abiotic stress, development, transcription factors and metabolism [82]– [87].

Induction of disease symptoms after infection of plants with ACMV has been attributed to the accumulation of miR159 and miR164 [98].

Both miR159a and miR159b shared overlapping binding sites in AC1 and AC4 at position 2242.

This transcription factor is a well-documented target for the miR159 family.

Twenty-one miRNA families (miR156, miR159, miR160, miR162, miR164, miR166-169, miR171, miR172, miR319, miR390, miR393-399, and miR408) seem to be universally expressed among diverse plant species (Fig 8).

Also, there were 3 miRNA families that were identified in bothbases, miR159, miR166 and miR399.

Eight miRNA families (miR156, miR159/319, miR160, miR166, miR171, miR408, miR390/391, and miR395) have been identified in the common ancestor of all embryophytes.

The miR166 family was the largest family with 11 members, while the miR399, miR2275 and miR159 families were the smallest only containing 2 members each (Fig 2B).

For example, miR156 targeted genes in the squamosa promoter -binding family, miR159 targeted a MYB-like regulatory protein [17], and mir160 targeted several auxin response factors (ARF10, ARF16, and ARF17).

For example, two miRNA families (miR159 and miR167), which had more than 7 K reads, can also be detected in qRT-PCR validation (Figure  1B, Additional file 2: Tables S4 and S6).

Another 10 annotated miRNA families – miR159, miR162, miR164, miR167, miR168, miR169, miR172, miR393, miR396, and miR398 – were also conserved in at least eight species (Table  2).

The repertoire of known bacterial-responsive miRNAs has increased and includes several families known to regulate hormone signaling, such as miR160, miR167 and miR390 involved in auxin signaling, miR159 involved in ABA signaling and miR319 involved in jasmonic acid signaling [13- 15].
